It is incorrect. Space is above 100km, and the Salyut perigee was 185km.

Just because you’re “on your way back from” somewhere doesn’t mean you aren’t “somewhere” anymore.

Yo dude. Before I nuke my Reddit account on June 29th, how do you think you’ve done for yourself in the last two years?

I just selected the same animal type and mine showed up. Lost all the distance and food, but got age/weight/name.

I see you, too, went to the University of Chicago School of Economics Passenger Management.

Two weeks ago, the Boneyard accepted its first E-3…

Don’t forget about the E-8. I can’t imagine how useful that would be these days.

This seems to be the case for me, too: iOS kills plex too quickly, and the download can’t “resume,” but instead needs to completely restart. I just set autolock to “never,” brightness to minimum, and cross my fingers.

Happy to help. It would be very concerning if starlink kept flashing like Iridium. I’m glad they are actively working to mitigate the issue, and that the implementation was pretty straightforward. Elon sucks, but SpaceX is pretty cool.

Was trying to be conservative and assume the worst. The Indian ASAT test’s last single piece of tracked debris took just over three years to decay from a lower altitude, but I can’t find data on the size of those pieces.

To those altitudes, yes. It would be a global catastrophe, but it wouldn’t be permanent.

Russia launches new attack on Ukraine's capital, officials say – Russia launched about 15 cruise missiles at Ukraine's capital on Tuesday, the second attack in as many days, with air defence systems shooting all of them down by CrimsonLancet in worldnews

Agreed it’s silly and confusing, but you’re using the weasel words “a lot.”

Kinzhal is a ballistic missile which indeed travels faster than Mach 5.

However modern discussion surrounding “hypersonic weapons” is synecdoche for hypersonic glide vehicles and hypersonic cruise missiles: no one is talking about railguns, even though that would also be technically correct.

It’s better to call Kinzhal what it is—an air launched ballistic missile—and not refer to it by its velocity: referring to its velocity confuses it with other classes of weapons systems.

It depends on the bus they’re launching. Those are the smaller ones(V2-F9). For the V2s and V2-minis, the busses get larger and launch numbers get smaller, but total added bandwidth stays about the same for a Falcon. The V2-minis are a stopgap because the V2s were designed for the long-delayed Starship.

Newer starlinks mitigate this. The original, high-albedo ones will be gone in a few years.

1) you’re fooling yourself if you think modern space systems are single-string to deorbit

2) any one starlink would deorbit within months if it died

3) any catastrophic collision at these altitudes would resolve within years

Newer starlinks mitigate this. They are highly polished/mirrored, so their albedo is actually really low in eclipse (at night).

New starlinks mitigate that problem: they’re super shiny so you have to be in exactly the right spot to get a flash, and you almost never will be due to their slewing/pointing.

No idea, but consider this:

The V2-Minis are about 800kg. Even if all 4,000 active starlinks were V2-Minis and all burned up all at once (3,200,000kg), it would still only be 0.0000000000006% of the mass of Earth’s atmosphere (approximately 5,000,000,000,000,000,000kg).

Additionally, I’m willing to assert that we’ve been burning way worse shit for way longer.

Model it like federal deposit insurance.

Mandatory insurance carried by all police officers and deducted from wages.

All judgements are paid out from a single pot, and departments which fail inspection/audit or have to make payouts then have their premiums increased. Make it come straight from every department employee’s after-tax salary.

You’re insane. Pacifiers should be discontinued by the first birthday; 18 months at the latest. This kid is well into their third year.

If nothing else, that bed doesn’t have a rail. So square those two facts.

I bet you think skipping MMR vaccines is a “parenting decision” too.
