Mars Once Habitable on This Week @NASA
[vid_tags]
Analysis of the first ever sample of rock powder collected by the Mars Curiosity rover has proven that the Red Planet location it’s exploring once had everything needed to support microbial life including a lakebed filled with not salty or acidic but fresh water. Also, innovative space technology; students help space exploration; women aspiring, inspiring; IceBridge preps; SLS @ TennTech; career day; and more!

Freakin Awsome
Good job !!
Like … 🙂
didn’t a rock from mars fall to earth with microscopic fossils in it proving this idea a long while ago?
It hasn’t been confirmed that they are fossils of bacteria yet.
why have the images stopped coming?? seems a little suspicious the images stopped coming the same time they made the initial announcement
fascinating journey
the subtitles are all wrong and say some stupid things at times.
I dont no how they would do this but they should think about having a ozone generator on a out side layer of the spaceship to protect them from solar radiation.
Hi
or just a electron magnet running the length of the ship with solar wind generators so the stronger the wind got the more powerful the field would get.
6:51 — 7:02: “They” have been helping “us”. Sounds kinda wrong…
These scouting trips are all fine and dandy, but this is just a drop in the ocean. We NEED to get up there and find out, when, how, and why all that water disappeared.

Who’s John Klein?
so mars was once habitable many years ago, my question is… what happened, why is it no longer habitable?
Solar wind stripped the lighter compounds like gaseous water and oxygen/hydrogen from the atmosphere and therefore the planet as a whole. Leaving behind the heavier carbon dioxide and solid water. Earth does not experience this atmospheric loss because of her magnetic feild. Hope this helps!
oh…ok; thanks : )
There are tons of things that need to be locked down in design and sustainability to make the trip worthwhile. No one wants to launch a multi-million dollar vessel up and shoot it towards mars to find out the astronauts dont have enough resources to survive getting there, let alone are protected by the craft during the transition. That is why these probes and rovers are extremely important. Without proper research, it’s a suicide mission and waste of money, time, and energy.
I feel that Mars is not the way for us to go. I feel that we should concentrate on building and developing human habitats on Luna (the moon) and developing bigger space stations. When we can build stations that can house 500 to 1,000 permanent crews and do R&D on advance avionics; then we can go off and settle and explore the rest of the solar system. The environment between Earth and Mars are a lot more dangerous than the space between Earth and the Moon; outside the protective sphere.
Look, I could be the doomsayer, but you can see the trends in money flow and it is looking very very ill indeed. So tell me, launch in 15 with what we have now, or wait for 25 and pray that the funds are going to be there? That’s the hell of this dilemma.
I don’t mean to the the downer on your party guys …
But seriously …
You are surprised to find an area with rocks that have sedimentary environmental similarities to … say … Lake Erie? Carbon Dioxide, Carbon, Oxygen, in the right levels?
Really?
That’s surprising?
Let me make it offical: Throughout the universe, on ANY planet from 10% to 150% Earths Mass, you’ll find areas with similiar rocks. Guaranteed.
On How the Universe Works (the series on disc.science) they think a giant asteroid got caught in mars’s orbit and charged the core over millions of years giving it a magnetic field therefore sustaining a rich atmosphere. Then after many millions of years the giant asteroid that give mars the magnetic field crashed into the planet and destroyed the top half of mars (there is evidence in this because most of the north area of mars is smooth and the south is rocky and covered in craters).
without a magnetic field to protect a planet from solar wind, the water turns to vapor and then blows away into space, the same could happen to earth. perhaps mars once had a magnetic field to protect its atmosphere but then lost it, and its water as well. i would like to know the exact reason as well.
You are Absolutely Perfectly Right and I simply couldn’t agree with you more! Chief Administrator Charles Bolden has recently declared that we Will & that we Shall go to a (yet not fully defined or more in detail pointed-out) Asteriod of some sort — but not until in about 2025! That is honestly VASTLY too late & way too modest; we Definitely need some whole a lot more Courageous deep Space goals to head on towards and MUCH sooner! Bring some more Budgetal Strenght to this!

Sorry, I hail from a background in physical chemistry and saying “water ice” is too vague in my opinion as water ice can exist in at least 15 different physical states.
Hey man thats really cool- i will need to watch it. Can you remember what episode it was?
No sorry, but it wont be hard to find if you google it 🙂
Kid at 5:34 looks like Forest Gump to me.
