space hard MCQ

Aerocapture uses atmospheric drag to insert spacecraft into orbit around a planet in a single pass, unlike aerobraking which requires multiple passes.

  1. True - saves significant propellant
  2. False - synonymous terms
  3. True - but only for Earth
  4. False - never successfully demonstrated

Answer: True - saves significant propellant

Aerocapture achieves orbit insertion in one atmospheric pass requiring precise guidance; aerobraking gradually lowers apoapsis over weeks/months. Aerocapture remains unflown but studied for Mars/Venus/Titan.
