How fast is the space shuttle?

Answer 1

== == Max speed so far is a little more than 17,500 miles per hour which is about mach 11-12. It achieves this speed when it separates from the external fuel tank, at the end of the burn of its main engines when it sets up for orbital insertion. It takes care of business up there, and then a short burst of the maneuvering thrusters slows the vehicle down and it begins losing altitude and setting up for reentry all the while decelerating. From the moment the engines are fired to take the shuttle out of orbit to bring it back to earth, it is slowing down.

Answer 2

The space shuttle could reach speeds up to 17,500 miles per hour (28,160 km/h) in orbit around the Earth.
