It’s such a harsh message to propagate, though. A lot of these smaller countries have been really pushing their space programs, and they don’t need “LOL, lander upside-down” memes to accent their recent failure any further.

At this rate, Japan may be able to actually land on the moon in a few more years, take some great pictures, and shove Mashable’s “space photo of the decade” quote directly up their ass. Where it belongs.

Yep, totally agree

I clicked on this post hoping to see something cool. Didn’t realise they were being pricks.

Getting shit into space is impressive, full stop. Ridiculing failure on the frontier is just sad.

ringwraithfish,

I’ve been binging on For All Mankind and it’s been a great reminder of how difficult space exploration actually is and how quickly things can go wrong.

The fact that they accomplished their goal of pinpoint landing within 10 meters of their target should be the lede.

I bet people in the industry are amazed by this accomplishment.

dustyData,

It’s the sad part of science communication. The pop culture sees difficulties and failures as indictments of character. In science, failures are the fuel of progress. In this case, especially in scientific circles, this was a massive success and is being celebrated as such. The upside down part is laughed at as just the price of making the unimaginable, possible. But most publications who don’t belong to science journalism just don’t understand.

SaiPenguin,

Why would that lead to shoving a quote anywhere? Much of the marvel of this photo is the unusual circumstances around it.

We’ve already got photos of the moon.

This, afaik, is the first photo we have a lander that suffered a significant complication in the landing but was still able to deploy a rover to take a picture.

“The lander was at most 10 meters off its mark, according to space agency officials, which is comparable to 11 yards or less.” Lol

Are we adding yards to clarify the distance for the benefit of American football players?

remotelove, w 'Old smokers': Strange new type of star discovered in Milky Way
@remotelove@lemmy.ca avatar

Betelgeuse is a red giant doing the same thing as described in this article? I wonder what the difference is.

Boddhisatva,

Good question. According to this article, the process going on with Betelgeuse does sound like the same or very similar to the process described in OP’s article.

The great dimming [of Betelgeuse] was caused by the star spitting out a lump of gas and dust, like chewing gum: or what scientists call a “surface mass ejection” caused by an “anomalously hot convective plume”.

OP’s article doesn’t say that the Old Smokers they found are red super-giants but since they called them old smokers, I’m inclined to think that they are. Also because they say that smoke contains much higher levels of heavy elements than is common in the region which would also be consistent with older stars. The article doesn’t say whether or not the stars puff out smoke on a regular schedule like Betelgeuse does, but then maybe they haven’t been watching them long enough to see a pattern yet.

It does seem like they found a bunch of older stars that are pre-supernova, just like Betelgeuse is, and burping out clouds of gas and dust.

remotelove,
@remotelove@lemmy.ca avatar

I missed it at first as well. The second paragraph implies they are red giants. However, there is a distinction between a red giant and a red super-giant, if that is what you mean.

The “peculiar” puffing behavior of these stars has never been seen before in such red giants, astrophysicist Philip Lucas told AFP.

Boddhisatva,

Ah, yes, I missed that. Thank you.

@remotelove@lemmy.ca avatar

So, in my typical nature, I went right to the source and shot off an email to Professor Philip Lucas from the University of Hertfordshire. He was one of the primary researchers for the original paper. (P.W. Lucas et al.)

If he responds, I’ll post it here.

@remotelove@lemmy.ca avatar
Boddhisatva,

Awesome! Thanks for contacting the professor and posting the reply.

@remotelove@lemmy.ca avatar

Of course! I was super curious myself.

Teachers generally want to teach so I have had great success reaching out to various people like that.

I don’t abuse that, of course. Keeping questions short and being respectful of their time is a huge plus, in my experience.

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.

Deceptichum,
@Deceptichum@kbin.social avatar

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,
@Tetra@kbin.social avatar

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

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.
