VubDapple, w Discovery Alert: A 'Super-Earth' in the Habitable Zone - NASA Science

Only 137 light years away. And that’s at the speed of light. It is out of reach to organic life but we might send AI out there

kowanatsi,

Just under 2 and a half months at warp 9

Why did they use a picture of a space shuttle?

They’re not allowed to show off the anti-grav vehicles yet.

fidodo,

Same reason the shuttles existed in the first place. To look cool /s

“Guardians” I don’t know how to feel about that.

gravitas_deficiency,

Yeah the Space force was created during the Trump administration…

@sramder@lemmy.world avatar

It’s more that it evokes two completely conflicting ideas. The optimistic idealism of my youth or the bitter cynicism of Verhovens Starship Troopers.

Pretty sure Trump just gave himself credit for it.

LesserAbe,

Yeah we would scoff at someone calling a soldier “guardian” even if they’re fighting for us, so let’s scoff at calling space soldiers “guardian” too.

Yeah, the attempts to distance themselves from the military aspect of it is not really engendering a lot of trust… “He’s going up to do *s c i e n c e,*low gravity research or something, various experiments, don’t worry about it.“

cyberpunk007, w ISS astronaut controls Bert the dog-like robot on Earth during simulated Mars mission

They say he can explore small caves, but wouldn’t this little guy be solar charged and they could lose him if he doesn’t have enough juice to get back to the surface?

What the hell is the blue thing going on in the background. That thing looks way cooler.

Tetra, w Map reveals all the space junk we've already littered on Mars

I'm glad the article mentions that in this case, it really doesn't matter; like, there seems to be nothing to 'pollute' on Mars (also 7 tonnes is not much at all). Bit of a strange headline to me.

xor,

if it gets contaminated with earth life the it’ll be harder to detect martian life…

PoopingCough,

You’re not wrong with your sentiment but i think it’s pretty safe to say that if we find life on Mars it’s gonna be trapped in ice somehow or deep below the surface. Besides having next to no atmosphere, it also has no magnetosphere which means it takes the full blast from solar radiation. Nothing living on Earth could survive outside on the surface of Mars.

Tardigrades could potentially survive, but they would starve to death.

xor,

we have quite a bit of life that thrives just under the surface… within nooks and crannies of dust particles… inside Chernobyl… in ocean volcanic vents…

i think mycelia are the only thing that can live off of just raw rock though (the vanguards of life)
but, spores are pretty small and everywhere…

personally i think we should get over looking for life on mars and seed it with whatever has the best chances…

a deep valley has a thicker atmosphere and more shade from the sun, btw…

Tetra,

I suppose so, but I believe they always make sure not a single trace of Earth life is left on the equipement they sent to Mars, for obvious reasons. So they already control for that.

Besides looking pretty messy, I'm not sure this does any harm.

xor,

nasa sure puts a lot of effort into it… can’t say i feel confident about other countries that crash into it…
on top of that, nasa has recently found that they’ve been breeding bacteria that lives off of their disinfectant, and so no they don’t already control for that.

XeroxCool,

Mars is inhabited by robots, but the Moon is inhabited by tardigrades because China crashed a lander.

xor,

this one?

Sad news for the tardigrades that were on board Israel’s Beresheet mission, which crash-landed on the Moon in 2019. Researchers have learnt that the microscopic animals, which can survive the vacuum of space and heavy-duty doses of radiation, wouldn’t have lived through the crash.

XeroxCool,

Wrong country and wrong outcome, I really nailed it. Given how hardy they are, I can’t say I’m convinced they’re all dead. Not that they’d actually be active without air and water

ShittyBeatlesFCPres, w Map reveals all the space junk we've already littered on Mars

Opportunity spent 15 years roving its ass off for this planet and now we have the nerve to call it “Space Junk.” No respect.

XeroxCool,

It proved it’s ass off because it thought maybe, just maybe, if It analyzed one more good rock, we’d let it come home since it’s original mission was only supposed to be 30 days.

WarmSoda,

Evaaaa!
Wallll-eeeee!

Reverendender, w Map reveals all the space junk we've already littered on Mars

Jesus, internet, I don’t want to know this shit anymore

atzanteol,

It’s fine.

Thorry84,

Chill, it’s a handful of stuff on an entire freaking planet. Sure Mars isn’t as big as Earth, but it’s still huge. You would be hard pressed to even find a single trace of man if you’re on that planet.

It’s a clickbait title, look at how bad the humans are. In the grand scheme of things this is a nothingburger. The benefits vastly out way the potential downside of dropping some stuff on another planet. Even if there is some trace of life there, dropping a little bit of stuff doesn’t harm it in any way.

Also remember the scale here, it shows as dots on the map, so you think there is a lot. But in reality the size of the stuff compared to the size of the planet wouldn’t even show up on a picture. It’s not even big enough to be a single pixel. If the resolution was 10x greater, it still wouldn’t be a single pixel. It’s like those maps where they show the space debris around Earth to make it look like there is a lot. It’s tricky to spot anything man made on Mars with high powered optics in a low orbit and knowing exactly where to look. If you can see the whole hemisphere, you ain’t seeing shit.

RizzRustbolt, w Map reveals all the space junk we've already littered on Mars

Kind of difficult to pick up after ourselves over there.

It’s wonderful to see how even at this scale there’s still that fractal-ish, dense and chaotic, but elegant and beautiful aesthetic that nature creates.

These are absolutely stunning. The James Web just brings so much magic of the universe to light.
