The space shuttle needs to go fast in order to reach orbit around the Earth. By going fast, the shuttle can overcome the gravitational pull of the Earth and enter into a stable orbit where it remains in space. This speed is necessary to counteract the pull of gravity and maintain a continuous state of freefall around the Earth.

The space shuttle could reach speeds of up to 17,500 miles per hour (28,000 kilometers per hour) in space. This high speed allowed the shuttle to enter orbit around the Earth.
It was designed to fly in space, and its first mission was another test of the space shuttle.
It takes approximately 3 days for a space shuttle to reach the moon from Earth. This timeline includes the launch, travel time, and lunar orbit insertion.
The Space Shuttle traveled at speeds of up to 17,500 miles per hour (28,000 km/h) in low Earth orbit.
