Fuel needs to be continuously supplied externally to keep accelerating the ship. The energy of the fuel that causes the ship's acceleration becomes the kinetic energy and the gamma mass of the ship. The energy in the fuel that accelerates the ship stays in the mass of the ship through its motion. The mass of the ship goes up. When the ship reaches its destination it must use fuel to slow down. So it must turn around and fire its engines. The energy that decelerates the ship causes the ship's energy of motion to decrease. As motion decreases the mass of the ship or its Gamma mass decreases. The energy used to slow the ship down causes the ship to loose total mass. The energy used to slow disappears or is expended. Deceleration reduces the mass of the shiip. The accelerating energy is conserved in the ships energy of motion. Decelerating energy destroys the energy of motion of the ship. The energy going into the deceleration or slowing down the ship causes motion energy to be taken away from the ship..

Einstein thought that Gamma gave the universe a wealth of extra energy. But he was wrong.

Accelerating energy becomes conserved as kinetic energy. And there is more resistance to acceleration as kinetic energy is generated.

Decelerating energy once used disappears. There is less resistance to deceleration because the mass is slowing down.

Energy and mass of matter are its measure of resistance to change of motion. Acceleration creates new motion while deceleration decreases it of which both are dectable by the frame by its experiencing a weight push in the opposite direction.
