It's radio waves. Takes about 125 mSec for a request to reach the satellite (it's 36,000 km up there) and then the same amount of time to come back down.
If you can reach a terrestrial data center in 10 mSec over fiber, the flying data center is 12x slower. And now, like the other replay said, do a TCP handshake and see how long it takes.
