Considering I pay for UA-cam premium, having ads embedded in videos is annoying, but having them blast at twice the volume of the documentary is ridiculous. Unsubscribed.
exactly.. that was the reason I got premium.. the ads would wake me up if I fell asleep while watching something.
💯
I totally empathize.
Yes there Ads do appear Twice as Loud as the Video.
I am suprised UA-cam did not Detect it during the Copy Right Scan.
I wonder why the editor or someone in the script room, don't include the first air date? I'm guessing around 20yrs, by some of the statements used.
According to the credits, this was made 2007/2008.
In what decade was this film produced? It seems old.
no u
@ 4:20 temperatures as "extreme" as 14 degrees Fahrenheit? What's so extreme about that?
Great vid!😁
Earth has an ocean inside it's crust right now.
Phoenix operated on Mars for 6 months in 2008.
We've had so many 'accidents' on Earth that led to life yet, 'improbably', it still happened here anyway.
Anybody really done a decent business plan showing the total amount of energy required to get X tons of material and fuel in order to make and operate a livable cocoon on a planet that effectively, has no resources?
(Please include running average daily fuel requirements. Got to transport that too. Estimated ship delivery schedule.)
Methane gas will be the fuel water all so
@@stanleydavidson6543 - The economy can not be based on that. There will never be a self supporting villages, towns or cities on Mars for various reasons, like economy, insurance and last but not least, the 38 % gravity of earth.
Lots of metal and resources
None of that when the new world was discovered
@@stanleydavidson6543 Do what? Uh, there was air, arable land, wood was the chief source of fuel but eventually coal was found. The New World was nothing but resources. Mars will be MUCH MUCH more difficult.
We can still save this planet.
THE WORST most inhospitable places on Earth, are FAR better habitats than any planet humans can land on (that is ONE planet, Mars).
The planet will be fine.. It's us humans who won't be fine.. The planet will revitalize itself once we are all gone.. just like after the Ice Age
Wonder they could introduce CFC's to mars to warm it up or any other really heavy heat trapping gasses
The theory that earth's orbit has been altered by a passing palnet can hold the same for Mars. Mars could have been in the goldilock zone and subsequently pulled from it orbit by this planet. While in the goldilock zone it had the same atmosphere as earth.
So they need to dig a well on mars and find out if there's water underground.
Maybe we had better try to keep our own planet inhabitable.
Exactly what I came to say!
If we can make another planet habitable, we can keep Earth habitable!
Let's do that first
But eventually we need to spread out, so our entire species isn't in one place in case of catastrophic events
We could keep it habitable, but that might not necessarily be in our control. We need a back up.
@@johnjackson8709but there's no profitable way to keep Earth habitable.
At least we shall go down in history of the universe as the Only species that couldn't save ourselves because there's no profitable way to do it.
Every good solution for keeping Earth good isn't profitable anyway so we shall never do it☠️
Giant Elementaries are involving in the background.
6 m is a bit less than 20', 10m is a bit less than 33'. I can't help but question if Mars ever had that much water to begin with.
I think Mars was planet A and Earth is planet B.
Elements certainly formed by water? Uh actual science would disagree with that statement.
How old is this documentary?
It's in the end credits, MMVII/MMVIII.
They are not telling us the real reason why we are going to Mars.
Its obvious Mars had water in the past but it was more than 2 billion years ago when its magnetic field still existed its just a shame Mars wasnt big enough to stay alive.
Mars will be hard for humans to inhabit. Extreme temperature swings from day to night and seasons, nothing to filter solar radiation and the regolith/ground is supposed to be full of toxic salts poisonous to humans and most life. Our bodies would be changed due to the lower gravity. It would take a lot of infrastructure set up on Mars before we can go there. Fish in a fish tank is an example of life support requirements within a confined space, waste needs removed and treated from the habitat constantly, on Mars it will need processed and recycled, food would be needed and propogated and take up a lot of square meters of habitat. Power supply would likely need to be nuclear supplemented with solar power and battery back up. Getting to Mars would be full of risk the body will start to waste in 0 gravity during the trip along with the risk of solar radiation. It will be tough but doable, it will take a very special team of people to take on this trip. Mars is likely far more hostile than we think as a bonus the day night cycle is simmilar to Earth. You would be as well living underground in Earth in a sealed habitat and never being able to go outside, this would simulate a lifestyle on Mars, not much fun.
whats the alternative?
We drag in some ice from the ort cloud and build a nuclear powered magnet to sit between mars and the sun and hey presto.

This is 16 years old.
Venus is the next Earth, Earth is future Mars and Mars future would be end into the Jupiter....
🙊
NASA needs to use the Water on Mars and Split it into Hydrogen and Oxygen and then into a cold Liquified Gas with Solar Power..
Then use thousands of Tuned Rocket Engines and RECONNECT the two Gases into Heat and Water Vapour Clouds, that also Absorb Sun Energy..
Not only would it start to Rain when the temp and pressure increases, it would also Lock In INFRARED "HEAT" to help Warm Up the Planet. ??!!
15 year old news.
No, it will never be "Plan B". Earth is plan B :P
The answer is very obvious: no, mars can not be our planet B. There is no planet B. There is no planet A either. There is only planet earth...
I don't know if we can find water w got everything else we need to colonize

dementia is hard
MARS is the ONLY planet humans can travel to... so Planet B it is,... dauhhhhhh!
Is it? Lol
@@AbortYurfetuses We can, if gov'ts spend enough money. All the other planets, humans can NOT land on.
@@KrustyKlown moons
We could travel to the twilight zone of Mercury if we figured out a super terrific radiation shield. Ya, I guess you are right. Rocky moons of the gas giants are the way to go. Jupiter craps out a load of radiation too, though. Anyways, you're right.
No. The aliens won’t allow humans to waste another planet. Simple as that.
Mars is done. Get over it.
The worst of Planet A will always be better than the best of Mars.
No it couldn't.
Maybe earth is planet 2 and we came from mars 10,000 years ago. Taking all the water with us to a new planet via iceball.
Terraforming will be initiated in Q3 of 2031 and will be completed in Q2 of 2036. It would be financially insane not to secure your patch of Martian land now ! Early adopters get a bonus oxygen pack !
3c will happen faster
Child number limits, NOW!
It's seems like all planets are already changing their own atmosphere since 2012.I believe all planets will just rotate themselves back to Alive.
Or the Earth way instead. Our own is changing to kill life and be like others🤔
That makes ZERO sense.
Bro is high as hell
@@chongli3007 So am I. But I can still think semi logically 😂😂
@@drconflict629 I think he means.. the planet will eventually revitalize itself
Mars too far away. Too cold can't be any life there never gonna happen. Never had water either. If is that cold water will simply freeze not possible to lose it due to thin atmosphere. Nonse the theory mars had water and it lost it in space. Ridiculous they even think about that
There's 1.3 billion cubic kilometres of water on earth 🌎. It's not too late to save the most beautiful place in the universe. Over population is the problem
Ok well you do your part and make sure you don’t have any children.
I believe it would be a death sentence to send anyone to a dead planet.
It took exactly halfway through the video to finally talk about the lack of a magnetic field. This video is way too long to be interesting.
I found it very interesting. No one forced you to watch it. You could easily fast forward or click off of it at anytime. So many negative people in this world.
watch it as you fall asleep.. it should send you into dreamland in no time
Whatever happened to Mask hype Mars settlement?
First
We are already living on B... we moved to earth 4.5 billion years ago, after we completely destroying Mars...!!? We already inhabited Mars billion of years ago and now we inhabited earth as a stop-gap planet while we find a new life....✌️
Tax all religions.
Could we really live on Mars? 100% no. Solar radiation would kill you before you get here. It is too cold, too dry and too toxic a place.
Intense solar radiation and cosmic rays due to lack of magnetic field will kill anyone.
Mars' atmosphere is 95% carbon dioxide, 3% nitrogen, 1.6% argon. Earth's atmosphere is 78% nitrogen, 21% oxygen, 0.9% argon, 0.03% carbon dioxide.
Mars has only about 0.7% of the atmospheric pressure of Earth. Mars' atmosphere is about 6.5 millibar, Earth's atmosphere is 1013 millibar. Surface of Mars is like Earth at 100,000 feet (30 kilometres) in the stratosphere.
Mars' atmosphere's humidity is 0.03%, Earth's average humidity is about 50% (lowest 0.36%, high 100%).
Intense ultraviolet solar radiation, due to thin atmosphere.
Alkaline pH soil at 8.3, due to chlorine in the soil. Earth's average soil pH is about 6.5. Toxic.
Virtually no oxygen at 0.13%. Earth at about 21% oxygen.
Mars is covered in dry iron oxide dust, has seasonal global dust storms, with a duration of about a month.
Mars' average global temperature is −81 °F (−63 °C; 210 K), Earth's average global temperature is 57 °F (14 °C; 287 K).
The seasonal Martian polar ice caps are mostly dry ice, frozen carbon dioxide atmosphere (CO2).
Comets falling on Mars bring some water and ice to Mars. The thin Martian atmosphere means the freezing, evaporation, and boiling point of water is all at the same temperature. Thus liquid water cannot exist on the surface of Mars .
No. Venus is the future Earth. Mars the past earth.
Before we go in to Mars core ejecting. Consider that degrees of a circle 360. That suggests to me that the Earth had a 360 day orbit when degrees were first conceived. The earth has as subsequent moved further from the sun to give a 365.25 orbit. The planets move out from the sun. The orbit extends.. The moon is doing the same right now. Venus will be habitatal in the future.
“The sun is the past, the earth is the present, the moon is the future. ' From an incandescent mass we have originated, and into a frozen mass we shall turn. Merciless is the law of nature, and rapidly and irresistibly we are drawn to our doom” Nikola Tesla
I think we should focus on keeping present earth.... present earth!
@@johnjackson8709 Unfortunately there are greater forces than us at work....
It's asteroids we're avoiding
1.5 c seems to have happened quickly
Boring
