Which one of the following statements best reflects the idea behind the “Fractional Orbital Bombardment System” often talked about in the 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.
▶ Answer & Explanation
Correct answer: C. A missile is put into a stable orbit around the Earth and deorbits over a target on the Earth.
The Fractional Orbital Bombardment System (FOBS) involves launching a missile into a low Earth orbit, from which it can then deorbit and descend upon a target. This allows for a less predictable trajectory compared to traditional ballistic missiles, potentially bypassing missile defense systems. The system prioritizes flexibility and surprise by utilizing orbital mechanics for delivery.
