I was only half listening to the story this morning, but apparently when our rockets fall back to earth there is some level of guidance or something to make sure it lands in a relative general area.  The Chinese apparently just said fuck it and let the chips fall where they may.  

 

I mean, its not rocket science.

 

OK, it is rocket science, but its not especially difficult rocket science.

It’s not a meteor. 

Yeah, it’s part of a rocket.   We know, it’s all over the news today.

Chinese Checkers is a racist provincial term, okay?

Now, if you'll excuse me---I have a tournament of Oriental Othello to prepare for.  It's reague night.

Is that YT right? The damn thing is climbing about 3 km/min.

It's natural for an object in orbit to gain altitude as it reaches its apoapsis, which is the "highest" part of the orbit. Then the altitude decreases as it approaches the periapsis. If the periapsis is low enough to where the object in space encounters some drag by brushing against the atmosphere, that decreases the altitude for the entire orbit over time until the object gets completely snagged by the atmosphere and plummets to earth.

So for satellites it is apogee and apoapsis applies to spacecraft? TIL.
Not exactly.

Apoapsis and periapsis are the generic terms.

*-gee means around Earth (perigee and apogee).

*-lune would be around the moon (perilune and apolune).

So, around Earth, both apogee and apoapsis are correct, but apogee is more specific for the body being orbited.

So, apoapsis is around your sister?
