Q. Consider the following statements about Halo Orbit:
1. These are influenced by the gravity of two bodies.
2. These orbits are highly unstable, maximising the amount of propellant needed to keep a spacecraft circling the moon.
Which of the statements given above is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: A
Notes:

Explanation: Halo Orbit:

  • Halo orbits are those influenced by the gravity of two bodies like in Gateway’s case, the Earth and the moon.
  • The influence of two bodies helps make the orbit highly stable, minimizing the amount of propellant needed to keep a spacecraft circling the moon.
