why when the international space station is only 250miles away does it take at least 4 hours to get there?

I’m going to be very disappointed if the rockets top out at 65mph.

Space is only 100km up. It doesn’t take that long to get up there, less than 5 minutes typically.

The Earth’s diameter is over 12,000km.

Blue Origin have been to space. That’s easy. In order to stay in space you have to go really fast around the planet, such that when you fall you miss the ground.

It doesn’t take long to get into space. It takes longer to make sure you stay in space. After that, to get to the ISS you have to rendezvous with it. Throw in a good chunk of safety margins and you get a lot of time.

A well timed ballistic rocket wouldn’t take that long to hit the ISS.

The ISS orbits the earth at 17,100mph relative to the ground.
