The 2nd one. It took me a while to figure this out myself, so I hope this helped. :D
The space shuttle is traveling at a speed such that its fall to earth matches the curvature of the earth. As a result, it is "falling" to the earth at the same rate that the earth's surface is rotating away, so it stays in orbit.
The entire space shuttle orbits the Earth, not just a specific part. The shuttle moves around the Earth in a controlled manner, following a specific trajectory set by its thrusters and guidance systems.
the space shuttle takes off like a rocket flies around the earth like a bird and lands like an airoplane
It takes 90 min to go around the earth in space.
This is known as free fall or microgravity. In this state, astronauts and objects inside the shuttle experience a sensation of weightlessness because they are falling at the same rate as the shuttle around the Earth, creating the illusion of being in a state of weightlessness.

54kg in newtons on earth weighs 529.2 newtons.
If your weight on Earth is 545 newtons then on the moon your weight will be 1/6 as much or about 9.6kg

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.
Horsepower is not used in space shuttles. Instead, the thrust produced by the engines is measured in Newtons or pounds-force. This thrust is essential for propelling the shuttle into space and overcoming Earth's gravity.
On earth, 504 newtons equates to about 51.4kg or 113 pounds. Dividing newtons by 9.8 gives you the mass (on earth) in kilograms.
A space shuttle can reach speeds of up to 17,500 miles per hour (28,164 kilometers per hour) when in orbit around the Earth. This velocity allows the shuttle to overcome the gravitational pull of the Earth and remain in a stable orbit around the planet.
One Newton on Earth is about 0.1653 newtons on the moon.
