❓ Frequently Asked Questions
What is gravity assist and how could the Moon contribute to it on an interstellar mission?
A gravity assist uses a celestial body's gravity to change a spacecraft's speed and direction without using propellant. The Moon could provide small trajectory tweaks or help shape the solar-system leg of a mission, but its effect is limited compared with larger planets.
How could the Moon serve as a base for fuel and supplies for long journeys?
The Moon hosts resources like water ice and oxygen in regolith that could be processed into rocket fuel and life-support consumables, enabling depots or refueling points before leaving the inner solar system.
Why is the Moon a good place to test habitats, life support, and robotics for long-duration space travel?
Its proximity and lower cost make it ideal for repeated testing of habitats, EVA systems, robotics, and autonomous operations, helping validate designs before venturing farther.
How can lunar materials help with radiation shielding for interstellar journeys?
Lunar regolith and water ice can be used as shielding around crew modules or fuel tanks, reducing exposure to cosmic rays and solar radiation on long interstellar voyages.
