Ganymede is one of the best places in the solar system for a space colony. There's plenty of water there and it's the only rocky body outside of earth, with a magnetosphere, to help shield from radiation. Not to mention that you would have an awesome view of Jupiter in the night sky, which would be absolutely stunning. It's also one of the largest moons, so gravity wouldn't be as bad as it could be on one of the smaller moons. It's in the middle of the solar system too, which could some day help provide a launch point for exploration of the outer solar system as well.
It is the largest moon in the Solar System. Not by much, but still :) Watching the Expanse series at the moment, where Ganymede was being used as the granary for the outer Solar System. Also mentioned that if you wanted to have healthy kids then women were sent there to give birth because of Ganymede's magnetosphere.
Why would its position have any advantages compared to Earth? Does it make it any closer to any other solar system? Once you leave Earth's gravity well, you better do not stop anywhere else but keep going until you get to your destination.
@@rd-gi6jw Then again, if you wanted to launch something (or someone) to Titan, or Pluto, or the furthest reaches of the Kuiper belt, you would be much better off launching it from Ganymede as a starting point, rather than Earth. That was my point about it's position to the outer solar system. It's a much smaller gravity well than Earth, and there is plenty of water there to produce rocket fuel, drinking water and oxygen. If there were ever a permanent settlement there, it would have the potential to make a good launch point for other deep missions to the outer solar system. That potential would obviously be some distant point in the future though.
@@nunyobiznez875 I stand corrected since you were actually talking about outer and not other solar system(s). On the other hand, you have neglected gravity pull of Jupiter. In order to get anywhere else in the Solar System you have to overcome gravity field of Jupiter as well. Jupiter though comes handy for the slingshot effect as in case of Pioneers, Voyagers and New Horizons. It helps adding velocity to space probes sent from Earth and heading to distant planets. It took only one year for New Horizons to get to Jupiter and use of Jupiter's gravity helped it reach Pluto in only nine years. On the other hand, as I understand, it will take about seven or eight years to send and insert new Europa probe into orbit of Jupiter. The reason for such a long journey is energy conservation. In other words, the probe travels slower in order not to have to break too much. Now, imagine you are already in the orbit of Jupiter and you want to travel to Pluto. You will still need a lot of energy to achieve the same or higher velocity that a probe from Earth had from the very beginning plus the gravity assist of Jupiter. Without going into math of all this, it may eventually even prove that you were right and that there is some advantage of using Ganymede for such missions but imagine the technology and materials you need to send in the first place to install an industrial facility on Ganymede capable to produce anything sensible that we would use to send farther on in the Solar System. We don't even know if Ganymede has any other accessible minerals except water. What about metals, organic materials and such. Are they present there in sufficient quantities? Imagine smelting iron ore on Ganymede! You will certainly agree with me that it doesn't make any sense to send all that stuff from Earth to Ganymede in order to be sent elsewhere from there. And I have not yet even started talking about threats of Jupiter radiation, which is why other posters mentioned Calisto as the better candidate.
Jupiter produces massive amounts of radiation itself. Maybe Ganymede's magnetosphere isn't strong enough to stop the radiation from such a close source as Jupiter.
Love the video of robots constructing a base. I think this could be a big part of the solution - having a pre-constructed base, while we keep measuring and observing every step of the way. By the time humans arrive, most of the problems should be worked out. A base such as the one visualized in the video might have several levels below-ground, for more shielding effect.
In another decade or two we’ll probably have the technology to be able to do this. We’re really close to having completely self driving cars And that’s the basic tech we’ll need for self operating construction vehicles/robots
@@atsylor5549 need a much better way to get energy to any type of Vehicle to use on mars, I love this Science and technology at this moment in time, I just regret that it took most of a lifetime to finely find my passion for work, 😂
Radiation, gravity (lack of) and the inherent issues with a completely artificial habitat seem like the biggest problems though it’s hard to pick which one would be the worst. Lack of funding perhaps will be the biggest hindrance.
We’d have to cross the lines of genetic modification to be successful I.e nit pick genes that would be most effective on the planet, create around 10k of these individuals, and let them terraform the planets before the mass movement of people may begin
Thats why habitats need to be under the martian surface. Orbital Habitats and surface ones can be shielded by lead and water, but only to a certain degree.
Nasa plans to use a type of structure as the Mars buildings to help protect against radiation, they're also very durable and can almost hold under pressure of some vehicles as tested, but will that be strong enough against other forces of nature on Mars?

And since earth’s 1.7 degree temperature increase in the last century has blown our minds, how would we manage Mar’s negative 100 degree decrease in temperature.
Regarding Gravity, constant acceleration set at +-1g would resolve the gravity problem. We would fix acceleration to 1g though plus start deceleration well in advance so is all nice at 1g....

Humans are viral and behave similarly. Viruses inevitably kill their host when numerous enough. Our host is the earth and there's no place like it within lightyears. We seem to be doing a fair job of sterilizing it despite this fact. So let's press on. Though viral, humans are quite fragile. Without some serious biological re-engineering, leaving the solar system let alone inhabiting local planets & moons long term is a no go.

@@hdaviator9181 yes. Perchlorates found in high concentration in the soil are highly toxic to humans, and the silicate in the fine dust (think talcum powder) can react in the lungs causing other toxins. Planting in the soil as described in The Martian doesn’t seem realistic to me.
@@billneo - What you say makes all sense: Lunar industrialization is needed in order to make portable homes to ship to Mars easily taking advantage of much lower Lunar gravity. Oh, wait, Lunar regolith is also bad, right? And the extremely cold nights last 15 days, right? And we can't hope to either ship fuel in sufficiently large quantities up there nor to extend sufficiently long electricity networks across the Lunar surface, right? So we are stuck with whatever batteries we can ship up there for every other forthnight... not promising for Lunar industrialization prospects, honestly. So, how?
@@LuisAldamiz nuclear power is the solution, pretty much for all space related operations tbh. As for the moon in particular theres the potential for using helium-3 as a fuel source for some fusion reactors, but how viable that actually is for sustaining a moon colony I dont know
A simple rear shielding of water-ice would suffice. This would be between the craft and the Sun, of course. . . . At approach to mars, it would be jettisoned, and useable at the destination.
skywatcher1972 , Wouldn’t water actually become radioactive after enough exposure? Personally, I think the best option is the strong magnetic field around the craft.
Darren Murphy , Yes. Water is a great “absorber” of radiation and the water in nuclear power plants is radioactive. That’s why I asked the question. Until we develop some sort of field to block most, if not all, of radiation, our presence in space will be limited and hampered. On a different subject, I don’t really see humans spending a great amount of time on Mars or even the Moon. The gravity is far too low and will have devastating effects on the human body. That is another problem we need to solve.
@Darren Murphy potentially near future technology could allow a actual fusion generator in large enough ships allowing for a full magnetic field generator
Im very sceptical for travel to Mars in this century. The only positive direction, I can give, is that Im sure that robots are better suited for Mars and longer out.
Probably could not be done . Since a person born on Mar would be only accustom to about 40% of Earth’s gravitational acceleration. Their bones and muscles would not be formed during growth to handle 2.5 times the force of Mars. Just a thought.
"There once was a young lady named bright, She could travel a bit faster than light, She left one day and in a relative way, Arrived the previous night."~Heavens to Murgatroyd
But in reality that could never happen. You can't come before you leave. It's just that information that you left would come after you have already returned. Basically, it's like watching a boxing match that happens on Earth, but you're on Jupiter. The match has ended and the winner is known... just not to you. So you can still bet, because nobody else on Jupiter knows the result, not even the betting place.
Gravity (or lack of it) is also a major problem for space exploration. Just my opinion, but in the near term we should use teams of robots to work on both the moon and Mars. Let them construct habitats and other structures. Then have humans move in. Robots don't care about food, water, radiation or gravity.
@@AtomicPunkBR Really? Then explain how the Mars rovers can function for years and years. Or how the satellites in space continue to function without issues.

@@georgesealy4706 It is easier to overcome the radiation problem in robots than biology of course, but it is still a very significant problem. This is part of why the rovers have very low intensity missions that last for years.
Not mentioned in the video, is spalling, which are flakes of material that spray outwards from an interior surface when the exterior surface is impacted. High energy particles are small, but they have a lot of kinetic energy. If those particles don't penetrate your spacecraft, don't just assume that you are safe.
We need a clear goal to go to Mars. And like the space race, we need something like the Gemini program to prove to ourselves we can survive in deep space. We need to go back to the Moon first and figure it out. Test out our technologies and techniques only a few days out, test the waters before committing to a journey which will take months either way. If we dive right into it, it'll be a disaster.
Totally agree that we first need to experiment with living on our moon for many years and experience all the trials & tribulations on it before we even think we can put people on Mars.....Because if we hurry up and try to put people on Mars it will be a complete disaster.....It's ludicrous to even think we are smart enough to do that.....We aren't!

It is a very bad argument, because travelling to other planets will answere so many questions that could help with problems on earth such as geographic and atmospheric studies which can reduce global warming....
I suspect that living in environments with relatively low gravitational fields will prove to be a health problem in long term or semi-permanent space missions. Rotating stations in orbit around planets or moons may be a necessity for healthy living or healing when needed.
@@skeetsmcgrew3282 Do you have a better idea? Using your supplies as protection from radiation is not that crazy of an idea, especially if you don't want to ship heavy lead or water to space.
Radiation is an important concern, yes, but then *everything* about space travel and visiting other planets is an important concern. Food, water, energy, gravity, boredom, etc. The distance to Mars is a lot greater than the distance to the moon, and they'll still need to carry all the food and water the astronauts need to survive the trip and back, not to mention the energy they'll need to travel there and back. I think we'll manage to do it eventually, but the 2030s seems rather optimistic at this point.
Not really. Once spacex gets starship running experiments in space or on the moon will become easy to conduct. The biggest hurdle in getting people at least to mars is going to be radiation protection. You cant get there if your astronauts are dying from radiation poisoning, which will happen en route if there is no solution.
@@kimjunguny I'm going to assume that radiation is if not solved, its on the way to being solved. Why? Because Elon wants to go to Mars. And he's not stupid enough to even try if he can't solve that problem.
With over 19 years' experience occupying the ISS and the new heavy lift rockets coming out, the food and water and life support gases are the "easy" part of such a trip. We can do that. We've kept individuals in space for many months at a time. We can easily assemble-in-space a large enough ship to get to Mars and back. We can pre-stage a lot of supplies on Mars' surface in advance at the intended landing site so the crew doesn't have to carry it all with them. These are all "stretch challenges" with existing technology, but quite doable. The much bigger problem, by far, is the radiation-in-transit problem. And I think a big part of the solution is to make fortified, hardened sleeping spaces that can be retreated to during solar activity -- much easier than fortifying the entire crew module. Gotta stay in your bunk rack for a few days? Equip the bunk racks for mild to medium sedation to ease the cramped-up times. After you solve for radiation, turn your attention to non-gravity. So far, wayyyyyyy underdeveloped is any kind of spun structures capable of providing gravity needed for such a long trip. Do we need a full 1 G? Doubt it! Even 1/2 G is better than no G.
Permanent settlements should start underground. The surface modules are always very pretty, but impractical. Underground will also allow for expansion.
It would work on the moon as well and we need to practice on the moon before we try Mars and build the space ships on the moon then size won't matter and neither will shape
It’s significantly harder to build a settlement underground than it is on the surface. I’m no expert but the only way that seems practical is if there was already a stable cavern underground that could be used and converted into a settlement. We would probably already need to have a permanent presence on a planet before we could start construction on an underground human settlement.
@@TheLunacyofOurTimes do you realize how long it took them to build tunnels in the 19th century? And the first people to colonize a new planet will be scientists and various experts not laborers. And before you think machines you should look into the size and weight of mining equipment. Like I said before you’d already have to have a permanent presence before building any significant underground structure. But you feel free to think that’s a doable first step.
@@atsylor5549 Limited thinking. A window to a Mars transit only opens briefly every 2 years. Of course initial residents would be highly and muli-qualified scientists and engineers. The first residents should be robots who can get a head start on what will be needed. Scientists are not going to spend 12 hours each day digging a tunnel.
It's amazing to me that the smallest atom, Hydrogen, is a good candidate for radiation shielding when the most common radiation shielding down here on earth is lead. I've heard of water-lined spacecraft proposed, but hadn't heard of the hydrogenated nanotubes. Fascinating! I suppose the key is to have the hydrogen tied up in a molecule in liquid (molecular water), or solid form (lattice, or tube form) as opposed to gaseous form where the atoms are spread far apart. I wonder if cryogenic hydrocarbon rocket fuel would have a dense enough hydrogen concentration to work.
The fear of low-level radiation is mostly superstition. The levels of radiation on the Martian surface may cause cancer or leukemia in 40 or 50 years, but the chances of the first Martian colonists living that long are really pretty slim. If we have learned anything from history, we know that the first colony will almost certainly be wiped out by some accident. However, we also know that we can protect people simply by piling dirt over the colony. There are likely other ways to do it as well that will be thought-of in due course. So, radiation isn't a real danger.
With NASA in charge, we'll be SOL. In my lifetime, NASA has managed to blow up 2 space craft and regress to having NO way to get astronauts into LEO. I look at a Saturn V like a medieval peasant in Rome looking at the Coliseum and saying, "That wasn't built by people, it must have been built by magic." Space companies however, that's more encouraging.
Seriously, though, every time I see something about colonizing Mars, it's all about 3D printed habitats or domes. I think a subterranean habitat would be better. You have the crust/regolith above you as a shield, and depending on the rock you're in, all you need to do is seal up the ends of the excavation. We currently use tunneling machines, here on Earth, that as they dig, they take the excavated material and turn it into wall panels and install them as the machine moves forward. Why not deploy such a system on Mars, or even the Moon. As problematic as the book was, "The Moon is a Harsh Mistress" did have a lot of really good ideas about how to build and maintain a space colony.
Radiation is just one of the many hurdles & risks out there right? Hope every single one of them is considered & prepared for, so that no lives would be lost in the process 🤞
We are in a galactic pin ball machine... nothing new. The planet was created by those things hurling through the universe. Jupiter tends to pull most object toward itself, kind of the guardian of the area. It is inevitable that earth will get hit again though.
An Earth-Mars shuttle that goes back and forth, never lands, and refuels in orbit could have ~any amount of radiation shielding you wanted. It would require cheap launches, to bring fuel to orbit - and we will have those soon.
Yes you are right. But more mass means more fuel needed. If Starship brings fuel up to orbit so cheaply as Musk promise that will not be a problem. So it is possible to have a decent shielding but it increases cost.
Space exploration is ultimately about the Human Race surviving after our star burns out. It's a long way down that "road" right now, but everything we as a species do now will help those who are closer to extinction.
@@xtscarfacem8255 You're thinking small. The issue is economics. The cost for traveling great distances in space are extremely high, and the reward is non-existent, while the risks literally include death. You can turn off all the wars on the planet and it will make no difference. It will be hundreds, probably thousands of years, if ever, before we can economically travel in space competently enough to think about anything beyond mining machines and research stations within our own solar system.

Unfortunately, you are likely substantially correct about that. It is easy to convince politicians to vote for trillions of dollars to build nuclear weapons to end civilization, but extremely difficult to convince them to pony up for moving our civilization (such as it is) to the stars (or for just avoiding turning Earth into kind of a pale imitation of Venus, say at 200 as opposed to 800 degrees F.). It's therefore no wonder that the space aliens haven't paid us a visit... "No intelligent life there, Zorborax... let's try again in say another 4 million Xeltrons and see if those primitive primates on the third planet, have learned anything yet".
We got to the Moon 50 years ago with grit, determination and in the spirit of exploration. Now we have the vision and the excitement back again for space travel, mainly because we have realised that single planet existence will ultimately bring about our extinction, I believe humans will absolutely get to Mars. Humans are a very resilient, inquisitive and persistent creature, never happy to stay in one place for long, now we know we 'need' to move off the Earth. I believe Mars is just a stepping stone to even bigger things. Watch this 'space' :-)
Distance. It is is just extraordinarily overwhelming. I mean for trips outside our own solar system. I always found the idea of colonizing planets on other systems inspiring, until I realized that unless we find a way to literally teleport across the universe, there is no point in colonizing. Lets take the closest earth like planet we know of so far. Scientists say that it is 40 light years away. That means that if we had established a colony on that planet, even if we could send messages at the speed of light between earth and that colony, it would still take 40 years to ask something and another 40 to get an answer!! That makes these two societies virtually unrelated and I find that thought quite sad...
The nearest star to ours - Proxima Centauri - is about 4 and a quarter light years away. With the fastest propulsion systems we have now for space craft - it would take 80,000 years to travel that distance. But on the bright side - if we can make space craft that go twice as fast as we have now - we cut that travel time down to a very reasonable 40,000 years.

Reminds me of the Terra Nova episode of Star Trek Enterprise. Just after Earth got warp drive they sent out a colony ship on a mission to colonize a planet. Getting there took like 20 years. By the time Enterprise got there many years later, the decendents of the colonists had changed quite a bit. And didn't consider themselves Earthers anymore.
@@thomasevans7829 To be accurate, there are a handful of observed planets that might be Earth-like. To claim we know anything more than that is WILDLY optimistic.

I think conquering GCR (Galactic Cosmic Radiation) on Mars is a pipe dream. I think that the dangers are too great to risk any astronauts journeying there. Especially, since Mars doesn't have a magnetosphere.
I think it will be essential for long space journeys, such as a trip to Mars. It shouldn't be too difficult either. All you need is tethered units. Ideally, you'd want a minimum of three. That way, docking and undocking can take place in the central unit while the whole thing is still rotating - no need to stop the rotation at any time. It could remain as an orbiter while a landing vessel makes the trip to and from the surface.
@@Speed001 Spinning up a rotating cylinder is feasible. The current plans are all insanely expensive because they intend to build everything at the bottom of Earth's gravity well and lift it into orbit for final assembly. The first step to anything other than a "road trip" to plant a flag and head home should involve a permanently manned manufacturing facility in orbit or at a Lagrange point using raw materials from the moon.
Artificial gravity has a number of very huge barriers, and the physics of it is not even viable from a theoretical standpoint yet. The physics of Gravity as a force is very isolated from the other fundamental forces of classical physics, and so in order to crack artificial gravity, you would have to generate a grand unified field theory that links gravitation to the other fundamental forces that we have already mastered. Once that is figured out, now you can proceed to design devices that can manipulate the gravitational field and can either amplify it or attenuate it at will and in a controlled and predictable manner. And furthermore, a device that can make use of the other forces which we already know how to operate such as electromagnetics in order to generate a gravitational field of a definite strength and a defined sphere of influence. Only then can artificial gravity become a reality. It may take several Einstein-level geniuses to crack all this.
I've always felt that eventually we will need to gene edit ourselves to have similar radiation resistance that say fruit flies have (fingers crossed we don't end up like Jeff goldbloom).
@Mark Ross That movie was a trip. Makes my skin crawl just thinking about it. Remember when his appendages starting falling off and he put them in jars in the medicine cabinet? Gross!
It’s a pipe dream. Nobody can think of any practical or economic benefit from such a difficult and colossally expensive operation. If a magnetic field can deflect Uranium nuclei at the speed of light, a nuclear reactor could be flown to power it, and it would be needed to have any possibility of powering the building activities shown. Although pointless, it would make more sense to colonise the dry valleys in Antarctica instead.

shielding space craft with water curtain is best. and the way to avoid additional weight is to fill the curtain wall surrounding the starship with water only before heading to MARS and after reaching earth upper orbit using a second starship filled with 100 tons of water instead of cargo!
In the Star Trek series, they used invisible shielding to surround the ship, which makes sense. Also the doctors would give some anti-radiation injections if they were exposed too long outside. Maybe S/F to us now, but gives the geeks something to work on. Our early cell phones were nearly exact copies of the communicator they used, down to the flip up top. 3d printing was culled from them too...just imagine having a food replicator and dialing up whatever you wanted to eat in seconds.

It just blows my mind how fucking perfect our planet is. Like not only did it have water, it was just at the perfect distance from the sun to sustain life. AND a magnetic field with an atmosphere to protect life. Just mind boggling we are this lucky
Is there something more pressing than Space Radiation? Nope, you nailed it. Human error #2. Human psychology would be #3. And smother Murphy's Law all over it.
you forgot the perchlorate.... Thats a big no no for human colonization... Thats why we will have Robot mining Mars and make rocket fuel and oxygen with it and build the real colony on the moon. it'll be our first shipyard for building gigantic colonial spaceship. low gravity,vacuum and lack of atmospheric pressure are perfect condition for building big and send to space easy.
@humanspan you forgot gravity, or rather the lack of it. coming in right after radiation. it'll wreak havoc with the health of long term mars inhabitants.
Gravity is an unknown. IDK, but I bet Martian gravity is perfectly okay for humans - as long as they stay on Mars. Astronauts have suffered some health problems in freefall, but .4G isn't freefall. If I'm wrong and low-G turns out to be bad, it's still not a big problem, just - everyone on Mars has to live on a giant, underground tilt-a-whirl. (Underground because of radiation.) Radiation and perchlorates and even gravity are easy problems to solve. Extracting water from the ground to make fuel and oxygen should be ~easy. So should growing food. Most of it seems "easy." IMHO, aside from paying for it, LANDING on Mars is probably the hardest problem.
Science Junkie 5 by 5 No, it doesn’t. Relax. There are lots of ways to learn about physics to understand for yourself, but the short version is that no, radiation exposure on Earth is not increasing. That was an issue twenty years ago due to ozone depletion (different to climate change), but as humanity has stopped using certain polluting chemicals, the ozone has begun to repair itself.
Some tardigrades are highly radiation resistant, also a fungus found at Fukushima eats radiation. maybe the fungus could be altered into an appealing food for the tardigrades, and a biosuit of pouch pockets could could act like living biotech radiation suit.
I think we will learn SO much once we start expanding into the solar system. We will make mistakes, but we will also make some great discoveries, as with any frontier we've embarked upon in the past.
There are many problems with a Mars mission to over come, like someone said in the comments already, Gravity, problems with the habitat, radiation, and money. But one of the biggest problems that people tend to forget is the mental problem. Serving for over a year (or more) with the same small crew on a different planet will effect the mind. Many people who are qualified in every other field may not be able to go because the fail at the mental part. Sure people have done test that isolated a crew of 3(? not sure how many was in this test) for over a year, but they were on Earth and they knew they were on Earth. NASA and ESA will never fully know the extend of the effect on the mind in a Mars mission will have until they do it. Another awkward problem is should the mission allow men and woman to go? Even if both the men and the woman have the procedure to not have children, romantic relationships are a possibility which could spark competition within the crew. This is not healthy and could be dangerous. So NASA and other have mention maybe having a single sex crew and make sure they are all straight to avoid a romantic relationships. They are many questions to be asked before we go to Mars, and many are tough questions, but we have to ask them otherwise we will never make.
Sounds a lot like a deployment. Lock a group of people in an output located in an isolated, hostile environment for a year or more and watch the fun/drama unfold. Human nature being what it is, certain things always end up happening in a fairly predictable progression.
Thus, Starship will bring large groups of people only. If setteling a new place, having both sexes on board is essential, dont you think? We are not going there to take samples and go home. The most people to fly to mars in the next 50 yeaars will intend to stay, live and prosper and ultimately die on mars. I think we should throw humans at mars until some stick.
Not if you work out hard. I’m talking about Olympic levels of training. I’ve seen how these astronauts work out, and they wonder why they are so weak when they come back from space. They have to train hard with a lot of resistance, but many of these guys don’t have an athletic background so it’s going to be hard.
I think that colonizing Mars will be very difficult. Since the atmosphere is almost gone the ground and soil is highly radioactive too, meaning the layers of ground / dirt they’d use as protection on the colonies is still radioactive.

The single biggest contributor to all the problems facing a manned Mars mission is duration. At three years, this planned mission time is just asking for all kinds of disaster to happen. The one single solution to pretty much all the challenges surrounding interplanetary space flight is a propulsion system that can accelerate the spaceship to about 500,000 mph. You could get to Mars in about 7-9 days, spend a week there, and return again in about 7-9 days. Total duration: about 25 days. The main problem not solved by high speed is, of course, low or zero gravity. However, ISS experience shows that getting through a 3-1/2 week Mars mission, with a week-long sojourn at 0.4g, would be relatively easy to manage.
As a species we have accomplished some amazing feats, but I really don't think we'll ever be able to become a space faring race. The obstacles are too many and beyond our capabilities to combat. My own gut feeling is space travel is too difficult, even for intelligent life forms and that being said we will never survive long enough to find an answer to the question of are we alone.
It is seldom mentioned, but genetically re-engineering ourselves is the better answer to many space travel problems. However once we have met that requirement, we will have also solved many, many of our other problems using it. Space colonization may no longer be of pressing interest. One of the alternative answers to the Fermi paradox is that advanced species would "move inward" rather than physically outward. Or that they adopt forms that are unrecognizable to us. Or another alternative is that if a species masters physics to the point of making long range travel feasible, the act of merely moving bodies to other planets may no longer be necessary or useful.
I don't know who would willingly leave Earth to live permanently on Mars, even scientists would need to return to Earth sooner or later for their own good.
they also plan to send people torwards venus. 50km to 55km above the surface of venus, the conditions are earthlike with air pressure like earth and a temperature that varies from 30°C to 70°C.
Great video. However, sometimes I wonder if we should focus also on projects right here on earth. How about a city under the ocean. Or a Highway under the ocean from the US to England. These projects have benefits to society to off set their costs.
Inculcation of Allah SWT to Space Exploration? Why Creator of skies wants you to look / visit skies? Why Inculcation of Quran to repeat / frequent, space visits. Because, looking at these huge skies and their organization, no mature and reasonable mind can say, it got created on its own and running since Trillions of years on its own. Analyzing skies made Abraham believe in God, so to everyone. If someone thinks this, It is by chance or on its own, he requires medical attention. الَّذِي خَلَقَ سَبْعَ سَمَاوَاتٍ طِبَاقًا مَّا تَرَىٰ فِي خَلْقِ الرَّحْمَـٰنِ مِن تَفَاوُتٍ فَارْجِعِ الْبَصَرَ هَلْ تَرَىٰ مِن فُطُورٍ ﴿الملك: ٣﴾ He is the One, Who created skies in Seven layers.

See how unwillingly and wontedly, all those who rebel Islam and Allah, NASA CSA ISRO ESA are forced to follow Quran and prove Quran authentic ? This is how Allah SWT make is mission go, even by using his Rebels.
Great video and very nicely done. I have no doubt that we will see boots on the Martian surface and eventually colonize the planet. However, the 2030s timeline may be overly optimistic. There are still quite a number of technical and health-related issues that need to be resolved. How to handle galactic cosmic radiation is clearly one of them. Another is how to land heavy (manned) spacecraft on the planet. The Martian atmosphere is thick enough to generate tremendous heat on entry, which is obviously undesirable, but it is too thin to sustain winged flight - even near the surface - or provide adequate atmospheric braking. A third issue is related to the fact that astronauts on long-duration flights may suffer optic globe edemas. With the current six-month missions onboard the ISS, this affects more than 1/3 of the astronauts. On a 2 1/2 year Mars mission, it would likely be more and possibly with far more substantial damage. Could artificial gravity resolve this? If so, what are the options: an on-board human centrifuge used for a few hours a day or a week, or a giant (probably unaffordable) Ferris-wheel type spacecraft like in 2001? It would be great if you could do a piece on one or the other (or both). Once again, great job! fcd
I strongly believe it will be easier and probably necessary to genetically engineer our adaptations to Mars than to adapt a habitat on Mars to our Earth self. We will build a Martian to live on Mars.
Superb animations in this informative video - thank you. The biggest danger to these notional long term missions comes from the human psyche - the isolation and close quarter confines will create incredible inter-personal tensions.
The main issue will be establishing a self sufficient base on Mars. The radiation doses are ‘highly fractionated’ and will not produce acute radiation sickness, however, they may increase the risk of certain malignancies such as acute myeloid leukaemia and lymphoma.
I'm perplexed by a certain scenario and need clarification. If a detector detects an event of these harmful particles and it's traveling close to the speed of light how would the detector be able to warn the occupants of the craft since the signal to warn and the event would both be traveling at the speed of light. I.e. how would they be able to relay the signal faster to warn?
I saw Halley's comet when I was a child, maybe I'll live long enough to see it come back in 2061... or maybe see people land on Mars before that... if it doesn't take too many decades to sort out all the obstacles, costs and people prepared to do it. Or if civilization doesn't collapse into chaos in the mean time. Space exploration would be a much lower priority when there are more urgent problems to solve on our own planet that need money, time, effort and ingenuity.
This makes me appreciate what we have right here on Earth: an atmosphere and magnetic shield.

Ganymede is one of the best places in the solar system for a space colony. There's plenty of water there and it's the only rocky body outside of earth, with a magnetosphere, to help shield from radiation. Not to mention that you would have an awesome view of Jupiter in the night sky, which would be absolutely stunning. It's also one of the largest moons, so gravity wouldn't be as bad as it could be on one of the smaller moons. It's in the middle of the solar system too, which could some day help provide a launch point for exploration of the outer solar system as well.
It is the largest moon in the Solar System. Not by much, but still :) Watching the Expanse series at the moment, where Ganymede was being used as the granary for the outer Solar System. Also mentioned that if you wanted to have healthy kids then women were sent there to give birth because of Ganymede's magnetosphere.
Why would its position have any advantages compared to Earth? Does it make it any closer to any other solar system? Once you leave Earth's gravity well, you better do not stop anywhere else but keep going until you get to your destination.
@@rd-gi6jw Then again, if you wanted to launch something (or someone) to Titan, or Pluto, or the furthest reaches of the Kuiper belt, you would be much better off launching it from Ganymede as a starting point, rather than Earth. That was my point about it's position to the outer solar system. It's a much smaller gravity well than Earth, and there is plenty of water there to produce rocket fuel, drinking water and oxygen. If there were ever a permanent settlement there, it would have the potential to make a good launch point for other deep missions to the outer solar system. That potential would obviously be some distant point in the future though.
@@nunyobiznez875 I stand corrected since you were actually talking about outer and not other solar system(s). On the other hand, you have neglected gravity pull of Jupiter. In order to get anywhere else in the Solar System you have to overcome gravity field of Jupiter as well. Jupiter though comes handy for the slingshot effect as in case of Pioneers, Voyagers and New Horizons. It helps adding velocity to space probes sent from Earth and heading to distant planets. It took only one year for New Horizons to get to Jupiter and use of Jupiter's gravity helped it reach Pluto in only nine years. On the other hand, as I understand, it will take about seven or eight years to send and insert new Europa probe into orbit of Jupiter. The reason for such a long journey is energy conservation. In other words, the probe travels slower in order not to have to break too much. Now, imagine you are already in the orbit of Jupiter and you want to travel to Pluto. You will still need a lot of energy to achieve the same or higher velocity that a probe from Earth had from the very beginning plus the gravity assist of Jupiter.
Without going into math of all this, it may eventually even prove that you were right and that there is some advantage of using Ganymede for such missions but imagine the technology and materials you need to send in the first place to install an industrial facility on Ganymede capable to produce anything sensible that we would use to send farther on in the Solar System. We don't even know if Ganymede has any other accessible minerals except water. What about metals, organic materials and such. Are they present there in sufficient quantities? Imagine smelting iron ore on Ganymede! You will certainly agree with me that it doesn't make any sense to send all that stuff from Earth to Ganymede in order to be sent elsewhere from there.
And I have not yet even started talking about threats of Jupiter radiation, which is why other posters mentioned Calisto as the better candidate.
Jupiter produces massive amounts of radiation itself. Maybe Ganymede's magnetosphere isn't strong enough to stop the radiation from such a close source as Jupiter.
Love the video of robots constructing a base. I think this could be a big part of the solution - having a pre-constructed base, while we keep measuring and observing every step of the way. By the time humans arrive, most of the problems should be worked out. A base such as the one visualized in the video might have several levels below-ground, for more shielding effect.
In another decade or two we’ll probably have the technology to be able to do this. We’re really close to having completely self driving cars And that’s the basic tech we’ll need for self operating construction vehicles/robots

How do we shield ourselves from radiation during the flight to Mars?
NASA: "Build a pillow fort!"
Tin foil hat helps as a deflector shield.
I would think that creating a magnetic shield like the earths that would block much of it in the same way our atmosphere does.
How about shortening the trip by way of Venus. You could knock off about 5 months off the trip with a gravity assist.
Bryan Heagy would take lots of power. Solutions they haven’t figured out yet. The power source needs to be innovated.
All that infancy training was not in vain!
Radiation, gravity (lack of) and the inherent issues with a completely artificial habitat seem like the biggest problems though it’s hard to pick which one would be the worst. Lack of funding perhaps will be the biggest hindrance.
We’d have to cross the lines of genetic modification to be successful I.e nit pick genes that would be most effective on the planet, create around 10k of these individuals, and let them terraform the planets before the mass movement of people may begin
Thats why habitats need to be under the martian surface. Orbital Habitats and surface ones can be shielded by lead and water, but only to a certain degree.
Nasa plans to use a type of structure as the Mars buildings to help protect against radiation, they're also very durable and can almost hold under pressure of some vehicles as tested, but will that be strong enough against other forces of nature on Mars?

@@hdaviator9181 yes. Perchlorates found in high concentration in the soil are highly toxic to humans, and the silicate in the fine dust (think talcum powder) can react in the lungs causing other toxins. Planting in the soil as described in The Martian doesn’t seem realistic to me.
@@billneo - What you say makes all sense: Lunar industrialization is needed in order to make portable homes to ship to Mars easily taking advantage of much lower Lunar gravity.

And we can't hope to either ship fuel in sufficiently large quantities up there nor to extend sufficiently long electricity networks across the Lunar surface, right? So we are stuck with whatever batteries we can ship up there for every other forthnight... not promising for Lunar industrialization prospects, honestly.
So, how?
@@LuisAldamiz nuclear power is the solution, pretty much for all space related operations tbh. As for the moon in particular theres the potential for using helium-3 as a fuel source for some fusion reactors, but how viable that actually is for sustaining a moon colony I dont know
The hydrogen protection idea is interesting, it's an abundant resource so it could be used widely on missions.
A simple rear shielding of water-ice would suffice. This would be between the craft and the Sun, of course. . . . At approach to mars, it would be jettisoned, and useable at the destination.
skywatcher1972 ,
Wouldn’t water actually become radioactive after enough exposure?
Personally, I think the best option is the strong magnetic field around the craft.
Darren Murphy ,
Yes. Water is a great “absorber” of radiation and the water in nuclear power plants is radioactive. That’s why I asked the question. Until we develop some sort of field to block most, if not all, of radiation, our presence in space will be limited and hampered. On a different subject, I don’t really see humans spending a great amount of time on Mars or even the Moon. The gravity is far too low and will have devastating effects on the human body. That is another problem we need to solve.
Darren Murphy ,
Very true.
@Darren Murphy potentially near future technology could allow a actual fusion generator in large enough ships allowing for a full magnetic field generator
Im very sceptical for travel to Mars in this century. The only positive direction, I can give, is that Im sure that robots are better suited for Mars and longer out.

Probably could not be done . Since a person born on Mar would be only accustom to about 40% of Earth’s gravitational acceleration. Their bones and muscles would not be formed during growth to handle 2.5 times the force of Mars. Just a thought.

Gravity (or lack of it) is also a major problem for space exploration. Just my opinion, but in the near term we should use teams of robots to work on both the moon and Mars. Let them construct habitats and other structures. Then have humans move in. Robots don't care about food, water, radiation or gravity.

Not mentioned in the video, is spalling, which are flakes of material that spray outwards from an interior surface when the exterior surface is impacted. High energy particles are small, but they have a lot of kinetic energy. If those particles don't penetrate your spacecraft, don't just assume that you are safe.

We need a clear goal to go to Mars. And like the space race, we need something like the Gemini program to prove to ourselves we can survive in deep space. We need to go back to the Moon first and figure it out. Test out our technologies and techniques only a few days out, test the waters before committing to a journey which will take months either way. If we dive right into it, it'll be a disaster.

Radiation is an important concern, yes, but then *everything* about space travel and visiting other planets is an important concern. Food, water, energy, gravity, boredom, etc. The distance to Mars is a lot greater than the distance to the moon, and they'll still need to carry all the food and water the astronauts need to survive the trip and back, not to mention the energy they'll need to travel there and back. I think we'll manage to do it eventually, but the 2030s seems rather optimistic at this point.
Not really. Once spacex gets starship running experiments in space or on the moon will become easy to conduct. The biggest hurdle in getting people at least to mars is going to be radiation protection. You cant get there if your astronauts are dying from radiation poisoning, which will happen en route if there is no solution.
@@kimjunguny I'm going to assume that radiation is if not solved, its on the way to being solved.
Why? Because Elon wants to go to Mars. And he's not stupid enough to even try if he can't solve that problem.
Agree. At the rate of advancement in AI and robotics, it just makes sense to send probes instead.
With over 19 years' experience occupying the ISS and the new heavy lift rockets coming out, the food and water and life support gases are the "easy" part of such a trip. We can do that. We've kept individuals in space for many months at a time. We can easily assemble-in-space a large enough ship to get to Mars and back. We can pre-stage a lot of supplies on Mars' surface in advance at the intended landing site so the crew doesn't have to carry it all with them. These are all "stretch challenges" with existing technology, but quite doable.
The much bigger problem, by far, is the radiation-in-transit problem. And I think a big part of the solution is to make fortified, hardened sleeping spaces that can be retreated to during solar activity -- much easier than fortifying the entire crew module. Gotta stay in your bunk rack for a few days? Equip the bunk racks for mild to medium sedation to ease the cramped-up times.
After you solve for radiation, turn your attention to non-gravity. So far, wayyyyyyy underdeveloped is any kind of spun structures capable of providing gravity needed for such a long trip. Do we need a full 1 G? Doubt it! Even 1/2 G is better than no G.
Yes I think low gravity and its effects on human body is even more challenging to overcome.
Ditto. Also energy and general material transportation issues, poisonous Martian soil, etc.

Permanent settlements should start underground. The surface modules are always very pretty, but impractical.
Underground will also allow for expansion.
It would work on the moon as well and we need to practice on the moon before we try Mars and build the space ships on the moon then size won't matter and neither will shape
It’s significantly harder to build a settlement underground than it is on the surface. I’m no expert but the only way that seems practical is if there was already a stable cavern underground that could be used and converted into a settlement. We would probably already need to have a permanent presence on a planet before we could start construction on an underground human settlement.

It's amazing to me that the smallest atom, Hydrogen, is a good candidate for radiation shielding when the most common radiation shielding down here on earth is lead. I've heard of water-lined spacecraft proposed, but hadn't heard of the hydrogenated nanotubes. Fascinating!
I suppose the key is to have the hydrogen tied up in a molecule in liquid (molecular water), or solid form (lattice, or tube form) as opposed to gaseous form where the atoms are spread far apart. I wonder if cryogenic hydrocarbon rocket fuel would have a dense enough hydrogen concentration to work.
The fear of low-level radiation is mostly superstition. The levels of radiation on the Martian surface may cause cancer or leukemia in 40 or 50 years, but the chances of the first Martian colonists living that long are really pretty slim. If we have learned anything from history, we know that the first colony will almost certainly be wiped out by some accident.
However, we also know that we can protect people simply by piling dirt over the colony. There are likely other ways to do it as well that will be thought-of in due course.
So, radiation isn't a real danger.
I was privileged enough to see a man step on the moon when I was 8. I so want to see a man or a woman step on the surface of Mars before I die....

With NASA in charge, we'll be SOL. In my lifetime, NASA has managed to blow up 2 space craft and regress to having NO way to get astronauts into LEO.

Hi Alex. I was 7. Think our dream is happening, too many players to fail now I think.
1:04 I want a cute radiation sickness. *frantic whispering in the background* Oh, "acute radiation sickness". Maybe not.
Seriously, though, every time I see something about colonizing Mars, it's all about 3D printed habitats or domes. I think a subterranean habitat would be better. You have the crust/regolith above you as a shield, and depending on the rock you're in, all you need to do is seal up the ends of the excavation. We currently use tunneling machines, here on Earth, that as they dig, they take the excavated material and turn it into wall panels and install them as the machine moves forward. Why not deploy such a system on Mars, or even the Moon. As problematic as the book was, "The Moon is a Harsh Mistress" did have a lot of really good ideas about how to build and maintain a space colony.

Radiation is just one of the many hurdles & risks out there right? Hope every single one of them is considered & prepared for, so that no lives would be lost in the process 🤞
Its almost scary the thought of all these things being hurled at the earth constantly.
We are in a galactic pin ball machine... nothing new. The planet was created by those things hurling through the universe. Jupiter tends to pull most object toward itself, kind of the guardian of the area. It is inevitable that earth will get hit again though.
An Earth-Mars shuttle that goes back and forth, never lands, and refuels in orbit could have ~any amount of radiation shielding you wanted.
It would require cheap launches, to bring fuel to orbit - and we will have those soon.
No need to bring fuel up. Extract hydrogen on oxygen from Phobos and Deimos at Mars and from the Moon back at Earth.
Yes you are right.
But more mass means more fuel needed.
If Starship brings fuel up to orbit so cheaply as Musk promise that will not be a problem.
So it is possible to have a decent shielding but it increases cost.
@@darkkennny1But, once the shuttle is in Space, it could be easy to add mass in the form of additional shielding, fuel, etc?

Unfortunately, you are likely substantially correct about that. It is easy to convince politicians to vote for trillions of dollars to build nuclear weapons to end civilization, but extremely difficult to convince them to pony up for moving our civilization (such as it is) to the stars (or for just avoiding turning Earth into kind of a pale imitation of Venus, say at 200 as opposed to 800 degrees F.).

Distance. It is is just extraordinarily overwhelming.
I mean for trips outside our own solar system.
I always found the idea of colonizing planets on other systems inspiring, until I realized that unless we find a way to literally teleport across the universe, there is no point in colonizing. Lets take the closest earth like planet we know of so far.
Scientists say that it is 40 light years away.
That means that if we had established a colony on that planet, even if we could send messages at the speed of light between earth and that colony, it would still take 40 years to ask something and another 40 to get an answer!!
That makes these two societies virtually unrelated and I find that thought quite sad...
The nearest star to ours - Proxima Centauri - is about 4 and a quarter light years away. With the fastest propulsion systems we have now for space craft - it would take 80,000 years to travel that distance. But on the bright side - if we can make space craft that go twice as fast as we have now - we cut that travel time down to a very reasonable 40,000 years.

I think conquering GCR (Galactic Cosmic Radiation) on Mars is a pipe dream. I think that the dangers are too great to risk any astronauts journeying there. Especially, since Mars doesn't have a magnetosphere.
Mastering “artificial gravity” might be a big one. It’s talked about, but none of these early “space industrialists” seem interested.
I think it will be essential for long space journeys, such as a trip to Mars. It shouldn't be too difficult either. All you need is tethered units. Ideally, you'd want a minimum of three. That way, docking and undocking can take place in the central unit while the whole thing is still rotating - no need to stop the rotation at any time. It could remain as an orbiter while a landing vessel makes the trip to and from the surface.
That's even more of a stretch than an artificial magnetic field.
None of the designs are practical enough yet.
@@Speed001 Spinning up a rotating cylinder is feasible.
The current plans are all insanely expensive because they intend to build everything at the bottom of Earth's gravity well and lift it into orbit for final assembly.
The first step to anything other than a "road trip" to plant a flag and head home should involve a permanently manned manufacturing facility in orbit or at a Lagrange point using raw materials from the moon.
Artificial gravity has a number of very huge barriers, and the physics of it is not even viable from a theoretical standpoint yet. The physics of Gravity as a force is very isolated from the other fundamental forces of classical physics, and so in order to crack artificial gravity, you would have to generate a grand unified field theory that links gravitation to the other fundamental forces that we have already mastered. Once that is figured out, now you can proceed to design devices that can manipulate the gravitational field and can either amplify it or attenuate it at will and in a controlled and predictable manner. And furthermore, a device that can make use of the other forces which we already know how to operate such as electromagnetics in order to generate a gravitational field of a definite strength and a defined sphere of influence. Only then can artificial gravity become a reality. It may take several Einstein-level geniuses to crack all this.
@@techsavannah maybe gravity is not a force but is a side effect
I've always felt that eventually we will need to gene edit ourselves to have similar radiation resistance that say fruit flies have (fingers crossed we don't end up like Jeff goldbloom).
Yeah that would suck. At least we could melt the arms off guys we didn't like as our final act.
@Mark Ross That movie was a trip. Makes my skin crawl just thinking about it. Remember when his appendages starting falling off and he put them in jars in the medicine cabinet? Gross!
Fun for sci-fi, but entirely unrealistic.
Amongst their many amazing attributes, Tardigrades produce proteins that protect their DNA against radiation.
I was a fly who dreamed he was a man but now that dream is over
It’s a pipe dream. Nobody can think of any practical or economic benefit from such a difficult and colossally expensive operation. If a magnetic field can deflect Uranium nuclei at the speed of light, a nuclear reactor could be flown to power it, and it would be needed to have any possibility of powering the building activities shown. Although pointless, it would make more sense to colonise the dry valleys in Antarctica instead.
The astronauts will will be shielded by the thousands of tons of equipment that will need to be sent to Mars. Yes. That will work fine.

Reduce travel time. Start finally using fission propulsion.
Ah yes, fix the problem of radiation with more radiation.
@@theperfectpeanutbutterjell7553 Works on submarine. Why it wouldn't work on spaceship?
@@kamilpotato3764 On a submarine the fission is used to heat water to create steam which in turn is used to turn a steam propulsion turbine which is used to rotate the propeller ... thus creating thrust.
On a space ship, the fission is used to heat ... what? You need to heat a propellant (like water) to be ejected for thrust. The problem is that there would be only a finite amount of the propellant of choice, thereby limiting the usefulness of fission ... at least at this time.
Although it has extremely slow acceleration, ion propulsion is a proven technology where you can run your "engine" for quite a long time before needing more xenon propellant.
Just my 2 cents.
Cheers!
perhaps use element 115 that was "discovered" back in the 80's
or if all true that still have not figured out how to reverse engineer a way to keep it stable
@@kamilpotato3764 this guy suggests cutting travel time by using the efficient nuclear thermal engine, in order to decrease the time astronauts are exposed to radiation, despite the fact that fission in the nuclear thermal rockets produces a lot of radiation.
shielding space craft with water curtain is best. and the way to avoid additional weight is to fill the curtain wall surrounding the starship with water only before heading to MARS and after reaching earth upper orbit using a second starship filled with 100 tons of water instead of cargo!
3.6 Roentgen - not great, not terrible, my people tell me that's the equivalent of a chest -X-Ray
a constant non stop chest x ray
In the Star Trek series, they used invisible shielding to surround the ship, which makes sense.
Also the doctors would give some anti-radiation injections if they were exposed too long outside. Maybe S/F to us now, but gives the geeks something to work on.

Gravity is an unknown. IDK, but I bet Martian gravity is perfectly okay for humans - as long as they stay on Mars. Astronauts have suffered some health problems in freefall, but .4G isn't freefall.
If I'm wrong and low-G turns out to be bad, it's still not a big problem, just - everyone on Mars has to live on a giant, underground tilt-a-whirl. (Underground because of radiation.)
Radiation and perchlorates and even gravity are easy problems to solve. Extracting water from the ground to make fuel and oxygen should be ~easy. So should growing food. Most of it seems "easy."
IMHO, aside from paying for it, LANDING on Mars is probably the hardest problem.
ASTRUM please please tell me. Have cosmic rays comeing into Earths atmosphere increased over the last 1,2 or 3 decades?

Oh, it's just I've heard that with the solar cycles getting weaker & weaker it's allowed in more cosmic rays into Earths atmosphere?
@skem
Indeed.
But the heliosphere does and when that weakens it lets more cosmic rays penetrate deeper into the central solar system.
Science Junkie 5 by 5 No, it doesn’t. Relax. There are lots of ways to learn about physics to understand for yourself, but the short version is that no, radiation exposure on Earth is not increasing. That was an issue twenty years ago due to ozone depletion (different to climate change), but as humanity has stopped using certain polluting chemicals, the ozone has begun to repair itself.
Some tardigrades are highly radiation resistant, also a fungus found at Fukushima eats radiation.
maybe the fungus could be altered into an appealing food for the tardigrades, and a biosuit of

Great video again 😊
There are many problems with a Mars mission to over come, like someone said in the comments already, Gravity, problems with the habitat, radiation, and money. But one of the biggest problems that people tend to forget is the mental problem. Serving for over a year (or more) with the same small crew on a different planet will effect the mind. Many people who are qualified in every other field may not be able to go because the fail at the mental part. Sure people have done test that isolated a crew of 3(? not sure how many was in this test) for over a year, but they were on Earth and they knew they were on Earth. NASA and ESA will never fully know the extend of the effect on the mind in a Mars mission will have until they do it. Another awkward problem is should the mission allow men and woman to go? Even if both the men and the woman have the procedure to not have children, romantic relationships are a possibility which could spark competition within the crew. This is not healthy and could be dangerous. So NASA and other have mention maybe having a single sex crew and make sure they are all straight to avoid a romantic relationships. They are many questions to be asked before we go to Mars, and many are tough questions, but we have to ask them otherwise we will never make.
That wouldn't make for a good movie though.
Prisons are a good example. Msny straight men Just go gey temporarily because of no choice. So even Single gender Crews might feel effects.
Don't over think the "mental" issue. US Navy submariners have been working in similar conditions for a long time.
Sounds a lot like a deployment. Lock a group of people in an output located in an isolated, hostile environment for a year or more and watch the fun/drama unfold. Human nature being what it is, certain things always end up happening in a fairly predictable progression.
Thus, Starship will bring large groups of people only. If setteling a new place, having both sexes on board is essential, dont you think? We are not going there to take samples and go home. The most people to fly to mars in the next 50 yeaars will intend to stay, live and prosper and ultimately die on mars.
I think we should throw humans at mars until some stick.
Zero gravity seems like it might be even more problematic than space radiation, especially for a trip that long.
Not if you work out hard. I’m talking about Olympic levels of training. I’ve seen how these astronauts work out, and they wonder why they are so weak when they come back from space. They have to train hard with a lot of resistance, but many of these guys don’t have an athletic background so it’s going to be hard.
I think that colonizing Mars will be very difficult. Since the atmosphere is almost gone the ground and soil is highly radioactive too, meaning the layers of ground / dirt they’d use as protection on the colonies is still radioactive.

The single biggest contributor to all the problems facing a manned Mars mission is duration. At three years, this planned mission time is just asking for all kinds of disaster to happen. The one single solution to pretty much all the challenges surrounding interplanetary space flight is a propulsion system that can accelerate the spaceship to about 500,000 mph. You could get to Mars in about 7-9 days, spend a week there, and return again in about 7-9 days. Total duration: about 25 days.
The main problem not solved by high speed is, of course, low or zero gravity. However, ISS experience shows that getting through a 3-1/2 week Mars mission, with a week-long sojourn at 0.4g, would be relatively easy to manage.

As a species we have accomplished some amazing feats, but I really don't think we'll ever be able to become a space faring race. The obstacles are too many and beyond our capabilities to combat. My own gut feeling is space travel is too difficult, even for intelligent life forms and that being said we will never survive long enough to find an answer to the question of are we alone.
It is seldom mentioned, but genetically re-engineering ourselves is the better answer to many space travel problems. However once we have met that requirement, we will have also solved many, many of our other problems using it. Space colonization may no longer be of pressing interest. One of the alternative answers to the Fermi paradox is that advanced species would "move inward" rather than physically outward. Or that they adopt forms that are unrecognizable to us.
Or another alternative is that if a species masters physics to the point of making long range travel feasible, the act of merely moving bodies to other planets may no longer be necessary or useful.

Great video and very nicely done. I have no doubt that we will see boots on the Martian surface and eventually colonize the planet. However, the 2030s timeline may be overly optimistic. There are still quite a number of technical and health-related issues that need to be resolved. How to handle galactic cosmic radiation is clearly one of them. Another is how to land heavy (manned) spacecraft on the planet. The Martian atmosphere is thick enough to generate tremendous heat on entry, which is obviously undesirable, but it is too thin to sustain winged flight - even near the surface - or provide adequate atmospheric braking. A third issue is related to the fact that astronauts on long-duration flights may suffer optic globe edemas. With the current six-month missions onboard the ISS, this affects more than 1/3 of the astronauts. On a 2 1/2 year Mars mission, it would likely be more and possibly with far more substantial damage. Could artificial gravity resolve this? If so, what are the options: an on-board human centrifuge used for a few hours a day or a week, or a giant (probably unaffordable) Ferris-wheel type spacecraft like in 2001? It would be great if you could do a piece on one or the other (or both). Once again, great job! fcd

Superb animations in this informative video - thank you. The biggest danger to these notional long term missions comes from the human psyche - the isolation and close quarter confines will create incredible inter-personal tensions.
No wonder our beloved earth is the luckiest of all planets...
I mean, it will probably be delayed again. I doubt we will actually visit Mars anytime before 2040, with habitation not happening before the 2050s.
The main issue will be establishing a self sufficient base on Mars. The radiation doses are ‘highly fractionated’ and will not produce acute radiation sickness, however, they may increase the risk of certain malignancies such as acute myeloid leukaemia and lymphoma.
we need to become resistant as roaches to travel space
hello wonderful Alex
I'm perplexed by a certain scenario and need clarification. If a detector detects an event of these harmful particles and it's traveling close to the speed of light how would the detector be able to warn the occupants of the craft since the signal to warn and the event would both be traveling at the speed of light. I.e. how would they be able to relay the signal faster to warn?
Astrum: Heat is harmless or even beneficial
US: Napalm?
UK: No!
US: What?
UK: White Phosphorus is better!
soon enough we will be needing kit like this on earth
I saw Halley's comet when I was a child, maybe I'll live long enough to see it come back in 2061... or maybe see people land on Mars before that... if it doesn't take too many decades to sort out all the obstacles, costs and people prepared to do it.
Or if civilization doesn't collapse into chaos in the mean time. Space exploration would be a much lower priority when there are more urgent problems to solve on our own planet that need money, time, effort and ingenuity.
I'm not sure why, but I liked this video more than usually. It's the same as the others, but still I liked it more. Strange. :)
