Have to pronounce onion like Justin Wilson, the Cookin’ Cajun. I gar-on-tee.

Thinking about grillions now. We BBQ's burgers last night, and I sliced some
onion to char on the side. So is a BBQ-charred onion called a grillion?

Here are some of the variables that will affect deorbit Altitude, mass, speed
and surface area. At the lower orbit aka 500km where starlink is there is still
some atmosphere so they are are getting air resistance and are slowing down. As
they slow down they get more air resistance until they fully deorbit. If I
remember right the starlink satellites need boosting nearly constantly or they
will deorbit and will deorbit in less than 5 years without the active
management. It has been also said the satellites have been designed so
completely break up during the orbit so that nothing reaches the ground.

I think it's about how much delta v required to de-orbit vs. park. For LEO
sats the DV is smaller to deorbit vs. park. For sync sats, it's just about
getting it above the very valuable sync orbit. So a small increase in orbit is
not much fuel. For lower than sync, it's a lot of unused space and a long way
down to deorbit so they usually stay where they are.

I think the best practice right now is to save enough propellant to boost your
old satellite into a parking orbit. The idea is we spent a grillion dollars
putting it up there, and someday we might harvest old satellites for material
rather than launching new stuff for a grillion more. You'd have to burn
propellant to de-orbit too, so if you're going to keep extra gas on the ship
then you might as well use it to park instead.
If Elon Musk wants to waste his own grillions by letting them burn up in the
atmosphere, then he can do that.

is there any accountability for debris left in space? like littering tickets?
why hasnt somebody like elon musk made a space roomba that just goes and pings
each item out of orbit back into the atmosphere since we know where it all is

I have this vague recollection that we currently can't even track all the
space junk. There was some lower limit, in the order of inches(?), below
which there isn't enough of a radar(?) return.
All I want to know, how long until Kessler syndrome? :)

Just because I know a bunch of you guys are interested in space stuff. Check
out this really cool site that shows every object in orbit around our
planet.
