I was a space kid, followed every space shot since 1965, was a super fan of Apollo 11, I had a subscription to Nat Geo growing up, just for the Space photos.

So I can't believe I'm saying this: Maybe we've gone far enough for now, and we should have a moratorium on space for the next 50 years.

We should concentrate on Earth for awhile, dontcha think?

Who needs the night sky when you can download the old night sky via satellite internet with gig speed downloads in vr? /s

Elon Musk is such a goddamned literal supervillain that he managed to make the theme of Firefly wrong.

Apparently, they can take the sky from you.

Ads on the fucking moon are going to do it for me.

Billionaires don't give a fuck about anyone but themselves, not even their kids. And, we've all agreed to let billionaires run the world, it seems.

They might put a million satellites into orbit, but they're certainly not going to be orbital data centers. At least not as we currently understand data centers. The idea that space is cold and therefore a great place to put data centers that get hot is the idea of a stoned moron talking out of their ass. Space is a vacuum, you know what else is a vacuum, the part of your portable coffee mug that keeps your beverage warm or cold for ages, because vacuum is a crazy good insulator. Just because space is cold doesn't mean the heat from an orbital data center can dissipate into it. This dumb idea is never going to happen unless data canter technology improves to the point where they aren't environmental disasters anymore.

It's either data centres in space or giant mirrors to reflect sunlight.

Presumably his engineers have explained this to him but he didn't listen

[–] fishy@lemmy.today 1 points 13 minutes ago

To cool the iss they're exchanging heat into water pumping to ammonia exchangers then radiated through infrared. The radiators for a space data center would need to be prohibitively massive as I understand it.

While this very well might fuck up land-based stuff looking at space, people are often overlooking what this would mean to stellar photography from space.

If they can truly launch these million data center sats profitably, that means starship works. That means payload to space is relatively cheap.

That means we could also send large quantities of large telescopes into space on the cheap, and avoid the crazy expensive cant fail telescopes because the cost to get them up there isnt prohibitive and a technical failure in the telescope isnt a disaster.

Things very well might change, but it will also open up possibilities in the same area.

[–] pigup@lemmy.world 9 points 50 minutes ago

Elon will not make it cheap. Falcon 9 prices keep rising. He's an exploiter and will enshitify his service once enough people are hooked on it.

[–] brucethemoose@lemmy.world 3 points 40 minutes ago* (last edited 37 minutes ago) (1 children)

Theoretically, even if we assume SpaceX is overshooting, that's an interesting thought:

launch cost chart

In practice? I'm more concerned about interest in funding astronomy in the first place.

That, and big fat telescopes are fundamentally expensive. And (at least for the optical variety) "swarming" them with a bunch of cheaper units isn't as effective as building a big one.

I'd love to be wrong though. There are some interesting papers on swarms of optical telescopes for a larger effective aperture, but I'm not qualified to assess them.

[–] NotMyOldRedditName@lemmy.world 2 points 33 minutes ago* (last edited 29 minutes ago) (1 children)

Oh, I wasn't thinking swarms the same way these million sats will be, I was thinking just using the whole payload diameter of around 9m for the lens/mirror (minus any housing) but they could potentially just buy the whole starship and be cheaper than past options and that is the housing.

James Webb cost billions because of it's complexity and launch costs, none of which is needed when there's 9meters to work with without any complexity at all.

If you wanted, you could make a super crazy expensive satellite that worked just like James Webb and have a massive mirror as well, but that's a bit different than my large quantity of cheaper telecopes in space. I wonder how big you could get the mirror if you did it James Webb style in starship.

[–] brucethemoose@lemmy.world 1 points 17 minutes ago* (last edited 15 minutes ago) (1 children)

I wonder how big you could get the mirror if you did it James Webb style in starship.

Presumably 7x ~8m hexagons folded up?

That is a good point though. And if one were to design a "budget" 9m space telescope, they could amortize the R&D dramatically by launching the same design many times, perhaps with different sensors for different purposes? Amortization is why the Falcon Heavy and such are so cheap, and why the Space Shuttle and JWST are obscenely expensive.

Okay, you've sold me. I hope this does happen.

[–] NotMyOldRedditName@lemmy.world 1 points 13 minutes ago* (last edited 12 minutes ago)

Ya, that would get costs down further if they were able to amortize it over a larger quantity.

We could also get them pretty far out with starship refuelling, but refuelling a starship back to full capacity to then go somewhere would raise the cost a lot. But imagine a 7x 8m folded hexagon one sent out into deep space. That would be super expensive though, we wouldn't get a lot of those haha.

This is all a massive big IF though. Starship being fully reusable like they think is still very far from a given, so none of this might come true in our lifetimes.

There are roughly 15,000 total at the moment ? I wonder what that will do to animals and insects lives.

[–] thedirtyknapkin@lemmy.world 14 points 3 hours ago

is already so bad. i do astro timelapses and it's all you see anymore. they stand out so much now, if the quantity gets 100x'd it'll be a nightmare.

it will blot out the stars...

exactly nothing as most animals and insects can't even see the stars; their sense of vision isn't good enough for that.

[–] some_designer_dude@lemmy.world 6 points 3 hours ago (1 children)

There aren’t many animals or insects in low-earth orbit though, thankfully.

[–] TheReturnOfPEB@reddthat.com 7 points 3 hours ago (1 children)

Yeah but they use the light to navigate too. They use this planet too.

[–] echodot@feddit.uk 3 points 2 hours ago

I think local illumination is probably going to be more of a problem than reflected light of a satellite.

[–] THE_GR8_MIKE@lemmy.world 23 points 5 hours ago (1 children)

Well that wannabe nazi took everything else, so why not the sky?

I thought they couldn't take the sky from me!

We haven't even finished burning the sky and boiling the sea!
