I love when the math part is explained, showing how it's done is really important. Most science channels avoid math cause it scares people but it only scares us because no one really knows what it is for and how it's used
In truth it takes a lot more time. In editing, I also noticed i said something wrong P^3 instead of P^2 so had to do some on the fly editing to fix. When any math is involved - you need to make sure its right - but it was really fun to do to be honest :-)
Yeah but the radiation is why we cannot. There is a years worth of radiation on earth in one day in deep space. That is why nothing is outside the magnetosphere. GSI and marco durante cover all this, as well does the website nasa debunked
When I was a boy I was convinced I could build a little spaceship that would accelerate with 1g forever. I calculated travel times under that assumption. I did a lot of stuff actually. A lot of physics studies and my own math when I was younger than 10. I was able to calculate how much I would age if I accelerate with 1g towards the Andromeda Galaxy and then slowed down. For some reason I wanted to go there.
Hohmann transfer is the second safest and third most propellant efficient way to reach Mars.... :) Therefore, the best all round way to get there for most crewed missions. Ballistic capture is safer and far more propellant efficient, and has a wider launch window, but is very slow, so unsuited to crewed missions. Using Hohmann transfer + aerobraking is also more propellant efficient, but introduces more risk, so loses out in safety terms. Great work crunching the numbers! :)
Holy Moly, what a fascinating and informative video. I won't pretend to understand all the information presented but understood enough to have a good feel about what's involved getting to Mars. Thank you so much for taking the time!
Thanks for explaining this! I always wondered what calculations are used and how it works. I'm not the best at algebra, but I'm really good at geometry, so the visualizations you did made it easy for me to understand.😎
Fun and useful stuff! I'm nearly done with a sci fi novel, and I was needing the length of journey and launch window frequency to go from Earth to Ceres. Plugging in the numbers for Ceres (2.8 AU and an orbital period of 1,682 Earth days) I get a journey, via Hohmann transfer orbit, of about 478 days with launch windows every 466 days. I flunked out of Algebra 2 forty-five years ago, so the clarity of your math was most appreciated!
really cool video! You made it really simple to understand with the visuals! excellent work! 🌍🚀 now we know how to get to mars... i hope the next video is a DIY spaceship!! 😉
a simpler explaination is that you use the earth's velocity to boost your speed to compensate for climbing farther out of the sun's gravity field to reach mars and then you use the sun's gravity field to assist in catching up to the earth's orbital speed on the return.
Nice explanation! From what I gather faster propulsion would need Mar's degrees to be higher(relative to Earth) in order to close the 180 in shorter amount of time. Fusion rocket here we come!
Thanks Dr Lieu for the explaining the math to get to Mars. Now that I have the math calculations in hand I just need to catch the next Mars Uber and I’m set to go. 🤣
This is great, but we need a nuclear thermal rocket and Nuclear electric propulsion (or something better) or we are not going anywhere near to Mars no matter how much math we do or how much Ellon dreams of it. Excellent explanation, and I believe that it's important that you give people the ability to think. Great job!
An exploration mission to Mars with you Dr Maggie as mission commander would be very exciting because you'd know how to break all the information down so they are easy to understand 😊
Thanks for yet another interesting, educational, and entertaining video Dr. Lieu. I know that I can always count on your content to lift me up and put a big smile on my face. Your enthusiasm is truly infectious. I wish that American school science teachers would start showing your videos in their classes to show that "young" people can be excited and enthusiastic about STEM. Keep up the Great Work. I hope that your dream of one day becoming an astronaut comes true sooner rather than later. Who knows, with so many new launches, you may yet get the chance 💯🙏 😺
Hohmann! Did you see that transfer! That's what I'm taking about! I almost was keeping up with those maths. So cool to aim where something is going to be months ahead of time.
Thanks for the explainer!! When seeing the animation of Earth/Mars on a Hohmann method, for years I've thought of some Fast / Furious action movie where someone jumps from one race car on the inside of the track to another on the next outside lane. Maybe Vin Diesel's character is wearing a jet pack. Anyway, seriously, thanks for the math lesson! It is a reminder how much we depend on orbital mechanics and gravity to do a lot of the work for us. We just have to wait our turn. And do the math!
Interesting math and well explained. So traveling to Mars is a short burst of activity and then about 9 months later some very busy and anxious moments. Sounds familiar.😊
Thanks, that was a lot of fun. Some suggestions have been made of using higher energy motors to get there faster, but I don't suppose a different orbit would be attempted?
@@SpaceMog There was no light pollution back then or street-lights. Being in Cornwall so no smog either. We had the first TV in the street and dad went to work on a RAF issue bicycle.
It depends if you think of the north pole as 'up' or the south pole as 'up' in terms of the plane of the solar system. If you think of north as 'up' then the planets orbit counter-clockwise. If you wanted to orbit clockwise you'd have to cancel out the orbital velocity of Earth, and then add it again in the other direction. It's less energy to flow with the river and paddle sideways to reach the other boat as you pass it.
I didn't actually draw it accurately on direction, like JohnnyWednesday says, it depends on what way is up but the rotation of the Earth acts as an additional boost for any spacecraft. So ideally you would launch east in direction, launching westward would actually work against the rotation, requiring more energy. Great question though thanks!
In principle yes, its called the oberth effect and often used to get to the outer planets, but its never successfully been used to get to Mars, direct trajectories are more energy efficient in tests.
In 2016, the SpaceX founder unveiled his grand ambition to set up a city on Mars. At that time, Musk hoped to see a crewed mission to our planetary neighbor happen as soon as 2024. Since then, the company has made a lot of progress in building its Mars rocket, but not quite fast enough to meet that initial timeline.
Nice video! Do you know if any mission considered a slingshot maneuver around the moon to save some fuel? And what about breaking against Mars atmosphere to enter it's orbit? Intuitively this might work. But then again it all ads complexity therefore raises risks...
@@SpaceMog I was hoping there was something additional set to launch. Escapade's sats are solar powered. They are planned to launch on Blue Origin. People have done some math that if Blue Origin misses the optimal Hohmann orbit dates, Blue Origin could have enough power for a more energetic orbit. Your explanations were good and apreciated.
super, was this after i asked about space flight calculation or just coincidence? the next part though is - space is three dimensional, so how do you calculate from lift off, to orbit, to transfer orbit. i am useless at maths and terrible at algebra, but this was pretty clear - and i think i commented last time that i've done animation work for ESA and (a long time ago) (on a planet far far away) the BBC series "the planets" back in 2000 ish. so, semi literate.
I used quite a few approximations in the numbers and also like i said at the end, Earth's/Mars' orbits aren't perfectly circular, so will also depend year on year :-)
Such a beautiful blouse, Dr. Maggie! Thanks for the math and the topic. I will add that if a rocket has significant enough extra Delta V or propellant, it could launch at any time and wouldn't need to wait for one of the launch windows to Mars that come every 26 months. The upcoming Blue Origin launch of the 2 Escapade satellites is like this. If it doesn’t get launched in the window, I believe there is sufficient Delta V to launch anyway. It's a fairly big rocket and the satellites don't have high mass.
@SpaceMog You're welcome! Yes, fuel is expensive! However, payloads and rockets can face delays. Then, do you wait for the next window if it's been missed? Also, people will eventually be on Mars, and might need supplies ASAP, or a more immediate return to Earth the other way. For these reasons, dates of launch outside of the true windows might be considered.
i have crazy idea for travel to mars its can change space race . we can do a lots of trip on there . not just mars if i can do we can go every where. its not change travel time , it could change the energy requirement in space.
So once we get to Mars, I guess we have wait there for another 2 years before we can come back? That is if we can work out a way of taking all that food and fuel there and having a rocket powerful enough to escape the not-so-insignificant gravity of Mars.
Perhaps I need to employ Dr Lieu to teach me algebra as it is why I failed to pass my 11-plus exam.As I never heard of algebra at 11 I resent that to this day, at 82. If the exam had just used Lit or the general knowledge I'd gleaned from my reading I'd have passed with flying colours & my life must have been entirely different. Or perhaps it was the death of my mother at two & a half years? In that case nobody can make any difference and I fear I must cancel my contract with Dr Lieu.
I wish the language of mathematics was a programming language I knew. And used descriptive variable names. How mathematicians and physicists get away with 'C' is beyond me. If I called something 'C' I'd get an email!
We know Earth's orbital period, and we know Mars' orbital period. Start counting degrees from when Earth and Mars are in conjunction / syzygy. (When both are in line with the sun.) If you've got a good telescope, when Mars is half illuminated by the sun, (half bright, half in shadow,) the angle from Earth -> to sun -> to Mars is 90°.
It is all well and good talking about it, but it is unlikely to happen what with all the problems associated with the trip which will probably be a one-way trip for some if not all. 1 - the amount of food they will require for 2 years 2 - the medical supplies for the just in case scenario, how do you treat a major injury without gravity? 3 - Fuel. If this was a serious endeavour, then it would be much bigger than Musk is telling us. Having garnered a lot of information from The Expanse, Musk's plan is a suicide mission, as you'd need 3 spaceships to go to Mars to ensure you'd be coming back. One in orbit, so you would have gravity if a major injury scenario occurred, one on standby if the main spaceship fell over on Mars, it is fine to land it on a pad on Earth, but it is another thing to land it on unknown ground on Mars. I've known engineers on earth where they could actually conduct tests on the soil still get it badly wrong when they worked on it. There is enough planning to get it out there but to "wing-it" on Mars is another thing altogether.

"How do we get to Mars" is an incomplete question. How do we get to Mars _alive and/or functioning still,_ given current tech, given 6-9 months in space not protected by the Earths magnetosphere, etc., the astronuts will be dead from the radiation many times over, and if not, their bodies would become so weak, they would need a functioning colony UNDERGROUND before they got there because Mars on the surface kills 10% of your brain per year (spoilers), and a way to grow food because the perchlorates in the soil are poisonous to humans and the amount of water needed to clean the regolith is cost prohibitive. Might as well contemplate meeting fairies in the woods of England. I've met a few here in NYC... I asked them how they got here! Talk about popular scientists leading the ignorant and uneducated down the garden path. Ffs.
@@SpaceMog Consider doing a set of short videos attempting to explain away these issues. NASA admitted the eye issues (nothing like going blind to spoil your day) when they came back from the ISS was irreversible, so if the ppl survived they'd be unable to move and see on Mars... and that's in Earth LEO where the radiation issues do exist even for the ISS if the go too far up they had to move the station down again because the retinal flashes from the gamma rays were too much of an issue. With the perchlorates and the "science" of the experiments saying humans can tolerate eating that just begs credulity, Sabine has a video _The Reproducibility Crisis,_ which is a major reason why I left academia, because at least in the US, studies are done _or not done_ whether or not the establishment didn't want the hypothesis (in the negative) against what evolved into today's ESG/DIE proven; so I left academia decades ago. So if you rely on peer reviewed research nowadays just because it's peer reviewed, that's a fool's errand. My gf in the 20th century did her Master's thesis looking at studies and found most were flawed to the point the study's conclusions were unreliable. She did that study while attending the Columbia School of Physicians and Surgeons, School of Nutrition. I would have married her, but God had plans instead for her to slowly die while begging me to find a cure for Multiple Sclerosis. No pressure. In the final analysis given "Rondo has electrolytes," in the current Western _Idiocracy_ I live in here, overlayed with Google's AI censors censoring everyone not just me these days to the point the regular pleb noticies his/her comments disappear, as Hillary once said, ..."does it really matter!?" I don't understand Musk's Pied Piper need to sell going to Mars when it's any life's death sentence, except some ppl need hope and as long as the don't look too deeply into the impossibility of the fairy tale sold, one segment of the population is controlled. The best I understand what Musk's real intent is for the Starships is to harvest the H3 from the Moon's regolith which would provide 1,000 years of fusion power for the remnant of humanity once that gambit is complete... Sry google censor territory. Hoping this reply won't be censored, a fool's errand, I know, but I always dare to dream, that is my nature.

Why is a clock-wise direction not an option or am I missing something basic Maggie?
It depends if you think of the north pole as 'up' or the south pole as 'up' in terms of the plane of the solar system. If you think of north as 'up' then the planets orbit counter-clockwise. If you wanted to orbit clockwise you'd have to cancel out the orbital velocity of Earth, and then add it again in the other direction.

I've known engineers on earth where they could actually conduct tests on the soil still get it badly wrong when they worked on it.
There is enough planning to get it out there but to "wing-it" on Mars is another thing altogether.
This works for unmanned probes too.
balistic xferr orbit is more efficient
Thats true but even longer to get there and won't get you into low orbit
We don't 😅
😭
@@SpaceMogOh! No! 😱
🌹🎁🎂😊
Mars, Pennsylvania?, you might use a bus.
it looks so pretty! I want to visit
Make sure you take coffins because you ain't coming home.
😢
Within kinetic translations towart distribuions towart arivle you youl use math oldo the masines when you start inbetween the troyans our not inbetween troyans and sun your iming pind to reached mars is diverendley do to simulat behavieures as whay the polericed sails satellite whare diamagneticle pushed in to diverend directions as was menten for it to go 🛸🥰🛸🎁🌟🎁🛸🥰🛸
It is not a money problem but a eurth resource problem with oll the money of eurth humans in existance would be without faleu if eurth resources can carry the demand of our presend existence towart our poseble behavieures of existance
You should use the toroidal behavieures within the princeple feildflow behavieures and go in to other direction to reach mars than you use outside eurth the direction fielflow of the kuiperbeld in stade of going axrose the equatorialcoronal towart kuipers demand.
Than you are dragged towart as phisicle trans location without feul
Our do you explained this from the southern side of experiencing this ?👀?
❤1.4 quarter one of the chants of music is not for noting In this harmonics behavieures
In a way when we look to eurth orbiting the sun from imbeeen the sun and galaxy center towart the next sun and inbetween the calaxy center to be inbetween again is devently not the same as the years mens experience as a orbit around the son❤
Go to poleriset translations and directional translations 🥰 and behold🐜
Ask the ETs what type of fuel they use for their flying saucer.. Chances are, the anwser will be, we don't use any.
We need to know!
Mars has Martians, or at least had,,,, on the surface back in the day
Where did they go?
You may ask Trump and Musk. They will move there. This planet is not good anymore
Some people would like that
mars is for amateur, i'm more interesting in going to uranus
When are you going ?
"How do we get to Mars" is an incomplete question. How do we get to Mars _alive and/or functioning still,_ given current tech, given 6-9 months in space not protected by the Earths magnetosphere, etc., the astronuts will be dead from the radiation many times over, and if not, their bodies would become so weak, they would need a functioning colony UNDERGROUND before they got there because Mars on the surface kills 10% of your brain per year (spoilers), and a way to grow food because the perchlorates in the soil are poisonous to humans and the amount of water needed to clean the regolith is cost prohibitive.
Might as well contemplate meeting fairies in the woods of England. I've met a few here in NYC... I asked them how they got here! Talk about popular scientists leading the ignorant and uneducated down the garden path. Ffs.
That would make a super long video, would you watch it to the end?
@@SpaceMog Consider doing a set of short videos attempting to explain away these issues. NASA admitted the eye issues (nothing like going blind to spoil your day) when they came back from the ISS was irreversible, so if the ppl survived they'd be unable to move and see on Mars... and that's in Earth LEO where the radiation issues do exist even for the ISS if the go too far up they had to move the station down again because the retinal flashes from the gamma rays were too much of an issue.
With the perchlorates and the "science" of the experiments saying humans can tolerate eating that just begs credulity, Sabine has a video _The Reproducibility Crisis,_ which is a major reason why I left academia, because at least in the US, studies are done _or not done_ whether or not the establishment didn't want the hypothesis (in the negative) against what evolved into today's ESG/DIE proven; so I left academia decades ago.
So if you rely on peer reviewed research nowadays just because it's peer reviewed, that's a fool's errand. My gf in the 20th century did her Master's thesis looking at studies and found most were flawed to the point the study's conclusions were unreliable. She did that study while attending the Columbia School of Physicians and Surgeons, School of Nutrition. I would have married her, but God had plans instead for her to slowly die while begging me to find a cure for Multiple Sclerosis. No pressure.
In the final analysis given "Rondo has electrolytes," in the current Western _Idiocracy_ I live in here, overlayed with Google's AI censors censoring everyone not just me these days to the point the regular pleb noticies his/her comments disappear, as Hillary once said, ..."does it really matter!?"
I don't understand Musk's Pied Piper need to sell going to Mars when it's any life's death sentence, except some ppl need hope and as long as the don't look too deeply into the impossibility of the fairy tale sold, one segment of the population is controlled.
The best I understand what Musk's real intent is for the Starships is to harvest the H3 from the Moon's regolith which would provide 1,000 years of fusion power for the remnant of humanity once that gambit is complete... Sry google censor territory. Hoping this reply won't be censored, a fool's errand, I know, but I always dare to dream, that is my nature.
I want to go to mars ..But not alone ..anybody wanna go with me ☺😺
I'll be right next to you
??? You Don't?
Why not?
