The air gets very thin the higher up you go, less atmospheric pressure. It is 8.3psi at see level, but greatly reduces as you climb in altitude. This is why car engines lose horsepower as they climb, like in Colorado. In aircraft sense this allows for greater efficiency in turbine engines propelling them faster on less fuel. There is much less wind resistance that allows vehicles to travel in a less dense atmosphere.

The ISS travels at 8km per second.
Per second.
Do you think that is possible with air up there?
Did you verify that with your radar gun, or are you taking Nasa’s word for it?
