Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Not much remains of them upon reentry. At least nothing that can be called e-waste.

That's the company line, but they're finding big pieces in fields in Canada.

I thought Kessler-syndrome was the real kicker, not greenhouse gasses.

LEO items can't Kessler. They can barely keep themselves from falling back through the atmosphere.

they just aerosolize creating even faster global warming

Wouldn't high-altitude metallic aerosols do the opposite?

[–] Quill7513@slrpnk.net 5 points 2 days ago (1 children)

unfortunately no. per my understanding the problem with starlink satellites burning up on re-entry are two fold:

  1. the aerosolized aluminum retains heat, not reflects it
  2. the aerosolized aluminum reacts with ozone, damaging a critical protective layer against the greenhouse effect

Should have made their frames with zinc alloy instead!
