Answer :
the mechanical energy of the shuttle-earth system when the shuttle lands less than when it is in orbit.
Mechanical energy is a matter of physical science. It’s the energy of an object that moves. All systems use mechanical energy to function, and we witness the energy of motion in our daily life. The Space Shuttle is the first reusable spacecraft and spacecraft that can carry large satellites both from and to orbit. It launches like a rocket in order to move int the Earth's orbit like a spacecraft, and at last lands down like an airplane. . The Space Shuttle consists of three components: A large External Tank functions to hold fuel for the main engines, then the Orbiter, which basically houses the crew; and last the two Solid Rocket Boosters which provide the Shuttle's lift for the first two minutes of flight. All of the components are reused but for the external fuel tank, which burns up within the climate after each dispatch.
