I'm just glad they have a ready-to-deploy backup plan. SpaceX is nailing it. I just hope that the future will remember the terrific work that Gwynne Shotwell and many others did while "someone else" where busy tossing money away.

Well, this was actually fkning concerning. Ofk is not like other Company aren't playing to launch thousand of satellites too. There should be a serious regulation and some heavy changes in the metal alloy used at very least. I'm sure that Trump already has a plan about it...

... ofk i'm fking kidding. Vote [everyone else] x president .

So we're starting to look at aluminum debris in the upper atmosphere, when are we going to look at carbon fibre debris? Or rocket fuel in the upper atmosphere? We dont know what any of that shit does. Im going to hazard a guess that it does nothing good.

If you were to light ten thousand Starlink satellites on fire in a bonfire on the ground people would put you in jail. When it happens in the upper atmosphere its called progress.

[–] ekZepp@lemmy.world 4 points 3 months ago (2 children)

Completely stopping the launch of new satellites will simply not happen. The only realistic response is to face the problem and improve the technology.

[–] Infynis@midwest.social 10 points 3 months ago (1 children)

That's the problem with capitalism. They won't improve the technology until we force them

[–] vrighter@discuss.tchncs.de 5 points 3 months ago

and the way to force them is to stop all launches until they fix it

[–] homesweethomeMrL@lemmy.world 9 points 3 months ago (3 children)

Just like they’re doing with the climate catastrophe.

Reasoned, sensible change, carried out quickly and paid for by the companies responsible.

[–] MelodiousFunk@slrpnk.net 5 points 3 months ago

It practically regulates itself!

We need better politicians.

[–] leftzero@lemmynsfw.com 1 points 3 months ago* (last edited 3 months ago) (1 children)

Well, it did work for the ozone hole.

It should work for the current climate catastrophe and the aluminium thing too, if about 50% of the electorate, 90% of its representatives, and 99% of the people in charge of big companies weren't mentally handicapped imbeciles, too (if we count being a psychopath as a mental handicap).

Alas, those were different times

Rocket fuel? You mean that stuff that makes water?

Falcon 9 uses kerosene.

At engine cut off and start up those big clouds coming out of the engines are propellant. The pumps need priming and they don't ignite right away or stop immediately after cut off. And what do you think they mean when they say "venting"?

Remember when Elon wanted to do transpirational cooling? What do you think they were going to "sweat"?

[–] JWBananas@lemmy.world 0 points 3 months ago

I, uh, know some of those words?

[–] yogurt@lemm.ee 2 points 3 months ago

Type of metal doesn't matter, it's any particle that leftover CFCs from the 1970s can stick to and make it more likely for them to react and destroy ozone. The ozone hole is over Antarctica and changes size seasonally because high altitude ice clouds do the same thing, smoke from forest fires also does it.

You can criticise them for that while being glad they are a reliable astronaut transport, unlike Boeing. The world is not black and white.

[–] FlyingSquid@lemmy.world 2 points 3 months ago (1 children)

I am glad of that, but this is what I responded to:

SpaceX is nailing it. I just hope that the future will remember the terrific work that Gwynne Shotwell and many others did while “someone else” where busy tossing money away.

Aluminum is a major element of the 5200 tons of stardust per year. Sadly found no numbers.
