Which one of the following statements best reflects the idea behind the â€œFractional Orbital Bombardment Systemâ€ often talked about in media?

A)

A hypersonic missile is -launched into space to counter the asteroid approaching the Earth and explode it in space.

B)

A spacecraft lands on another planet after making several orbital motions.

C)

A missile is put into a stable orbit around the Earth and deorbits over a target on the Earth.

D)

A spacecraft moves along a comet with the same speed and places a probe on its surface.

Correct Answer : A missile is put into a stable orbit around the Earth and deorbits over a target on the Earth.

Note :

A Fractional Orbital Bombardment System (FOBS) is a warhead delivery system that uses a low earth orbit towards its target destination. Just before reaching the target, it deorbits through a retrograde engine burn.

The idea behind FOBS is, a warhead is put into a stable orbit and it deorbits over the target.

If the target and the launch position is lined up and the warhead keeps going round, it will complete a circle.Obviously, with the earth moving during this, it is more of a spiral than a ring, but the horizontal movement is countered in such a way that the warhead still goes over the target.
