❓ Frequently Asked Questions
What is the Moon's role in space navigation?
The Moon provides a stable celestial reference and a gravity source used to calibrate spacecraft tracking, plan trajectories, and execute gravity-assist maneuvers.
How can missions use the Moon for gravity assists?
A spacecraft can swing by the Moon to gain or lose speed and change direction, enabling fuel-efficient routes to other destinations or to enter lunar orbit.
What is Lunar Laser Ranging and why does it matter for navigation?
By bouncing lasers off mirrors left on the Moon, scientists measure the Earth–Moon distance precisely, improving orbital models and timing used in navigation.
How does the Moon affect spacecraft in Earth orbit?
The Moon's gravity perturbs Earth-orbiting spacecraft, so navigation models account for its pull to keep precise positioning during maneuvers and station-keeping.
