How fast does the shuttle rocket have to accelerate to get into space?

Answer 1

The orbit insertion velocity near the Earth's surface is practically the same as the Earth escape velocity of 11.2 kilometers per second, or 25,805 miles per hour, or Mach 37!

Answer 2

The shuttle rocket needs to accelerate to about 17,500 miles per hour (28,000 kilometers per hour) to reach low Earth orbit. This acceleration allows the rocket to overcome Earth's gravity and achieve the necessary speed to enter space. The acceleration rate can vary depending on the rocket design and mission requirements.
