Detailed explanation-1: -Like any other object in low-Earth orbit, a Space Shuttle must reach speeds of about 17, 500 miles per hour (28, 000 kilometers per hour) to remain in orbit.

Detailed explanation-2: -The final orbital speed of the space shuttle is approximately 28, 000 km/hr (17, 500 mph).

Detailed explanation-3: -Because the rockets that launched the components of the ISS started on a rotating surface (the Earth), the speed of that rotation is added to the speed the ISS travels in its orbit, meaning we didn’t have to burn as much fuel to get to 17, 500 mph (28, 000 km/h).

Detailed explanation-4: -Well, the question is about how fast do the space shuttle and International Space Station travel in orbit. They go 17, 500 miles per hour. That velocity is necessary in order to stay in orbit and not fall out and return to Earth. There’s really very little sensation of the astronauts going that fast.

Detailed explanation-5: -Satellites in low Earth orbit The orbital speed of 7.8 km/s (17, 500 mph), refers to the LEO regime just above the Earth’s atmosphere. At higher altitudes, the speed required to keep a satellite in orbit changes. In fact, this actually decreases with the increase in altitude.
