This is pretty exciting. More than what I was expecting actually.

 

[SJRB]

HOLY SHIT DUDE

 

[Omegasquash]

Not to mention the huge doses of radiation. Humans would have to live underground or in a bubble. At least until we terraform the planet.

Which would take a very, VERY long time.

 

[everyday math]

Since when is liquid water flowing on the surface. Not exciting?

NASA deserves to show it off however they desire.

 

[EASTC0AST_GH05T]

No, an unprotected human would die pretty fast on Mars. If it was an environment someone could walk around comfortably in, it probably would already have trees and stuff. However, it is theoretically possible to make it into an environment that people could comfortably walk around in, with a few centuries worth of planetary engineering. That's probably not worth the effort though. On the other hand, you could build an air-tight shelter on the surface of the planet fairly easily and just live in that. It wouldn't be as difficult or dangerous to live in as a spacecraft, since you would have some gravity and no risk of being sucked into a vacuum.

Understandable, another fun fact is Mars has a very low thermal interia which means the surface heats up really fast when the sun shines on it.

People say this, but I am wondering what they expect to do about the magnetic field issue? Mars is a dead planet, all the alien ice-melters on the planet are not going to protect against solar storms.

 

[viHuGi]

When are NASA going to Mars? 2020?

 

[Clefargle]

NASA confirmed it! Stay losing hard g'ers.

Yes! Anyone using a hard g is a science denier from my point of view

 

[everyday math]

When are NASA going to Mars? 2020?

Nope. Not till like 2030+ I believe. Correct me if I'm wrong.

Another rover is scheduled for Mars around 2020 tho.

 

[Slayer-33]

Fuuuuuuck

Also it's GIF not JIF

 

[Bronx-Man]

Hard g'ers get rekt

 

[Epsilon-delta]

A rover is going to Mars by 2020. If you're talking about a manned mission to Mars then that's up in the air.

 

[Wind's Howling]

This is quite asthonishing news and anyone who expected anything remotely bigger needs to get their reality checked.

 

[cdyhybrid]

Water on Mars. Get a probe up there to analyze the water!

When is the Martian summertime?

 

[KingSnake]

I know the implications, read what I said, just announce it without the theatre.

They need financing, so the theatre is a must have.

 

[EASTC0AST_GH05T]

Matt Damon will be on Mars this friday at a theater near you.

 

[everyday math]

Yeah I just edited it. I guess they do want to do a manned flight to Mars around 2023. Didn't know about that.

Boots on the ground won't be until around 2030 unfortantly.

 

[Einchy]

Aw shit, we infected Mars with our germs. I give them ten years before they have a nuclear war.

 

[KingSnake]

Even of this was suspected before, having the proof for it is big step forward. I guess being sure about the source of it will be the next step.

 

[andycapps]

Sweet, can't wait to take summer vacations to the beaches on Mars.

But really, this is cool to know.

 

[cameron]

From the Q&A, Jim Green said they now know what to search for with MRO/HiRISE due to this science finding. Also,

*points at you, thumbs up. wink*

I seriously doubt we'll go to Mars in any of our lives time. Isn't the travel time like... 2-3 years? Or am I exaggerating the distance?

The distance to Mars varies, but trips are planned for when it is closest to Earth. It took 253 days for Curiosity to reach Mars.

Depends on when you go, but it's under a year.

It will happen in our lifetime. Unless something catastrophic happens in the next 20+ years that would prevent NASA from landing there.

 

[Mufc1427]

Man that's a huge discovery.

It will happen in our lifetime. Unless you're 50+, you'll see a boots on ground manned mission to Mars.

Probably not humans, no. It's a drone/robot/android/rover future. We won't go unless we really, really have to.

 

[Busaiku]

NASA confirming soft g is pretty major.
It's science now.

 

[commedieu]

Welp. Thats that then... so we've got the building blocks of life on another planet.

That is significant to the history of mankind. Props to those involved in the discovery.

 

[oti]

Okay. You go and find us a planet for us to live in.

 

[Tinfoilhatsron]

Oh hell yeah, so damn exciting!

 

[Epsilon-delta]

Scientist on the stream said NASA knows there's an underwater ocean on Europa and they'll be exploring that within the next decade.

let's start planting some goddamn trees already

16 HiRISE images with captions about RSL. http://www.uahirise.org/releases/rsl/

Recurring slope lineae (RSL) may be due to active seeps of water. These dark flows are abundant along the steep slopes of ancient bedrock in Coprates Chasma.

 

[EASTC0AST_GH05T]

definitely could see myself living there.

 

[Fury451]

What were you expecting, a Mass Effect relay?

This got me good. Legit lol.

 

[lawnchair]

i would drink this water

 

[HelloMeow]

So what. Water is on Mars. That doesn't mean humans can live there let alone go and survive there.


Does Mars even have an oxygen-based athmosphere? I don't think so.

It's very easy to turn water into oxygen + hydrogen. It's what they do on the ISS.

Mars isn't protected against solar radiation that well. Thats another contributor to why life isn't there.

Seems that it would need a magnetic field, and an atmosphere.. but, I wonder if one comes with the other.

 

[Bit-Bit]

OH SHIT.

Time to pour all of our money and engineering towards getting our ass to Mars to gather samples.

The former is never happening, so the buck stops there.

The only use Mars will have in the future is resources and a stop gap.

 

[Apath]

Wouldn't any water on the surface just evaporate?

 

[darkazcura]

Wouldn't any water on the surface just evaporate?

The salt/perchlorates in the water raises the evaporation point.

Still better than being on a spacecraft. Besides, for the most part you just need a sufficient amount of mass to block space radiation. An O'Neill cylinder built in space could block the radiation from solar storms just with the mass of its structure. If it is an issue on Mars, they could just live in a sufficiently shielded structure. People won't be out wearing straw hats and farming with a hoe on Mars after all. They will be living indoors.

You said people can go for a walk after a few centuries of planetary engineering, I'm saying that's not happening. Mars is a gonner .

No worries, Matt Damon is going to science the shit out of this.

I never use the word "cringe" and I try so hard to ignore cringe culture but that line makes me scrunch my face into a two-dimensional plane. Shame on you matt
