The Moon is the nearest natural laboratory for Solar System science and human spaceflight. Its surface preserves traces of ancient impacts and geological processes, while its proximity enabled Apollo to make the first human expeditions to another body.

Lunar missions must combine precise navigation, orbital braking, landing, and safe return. The Moon therefore remains a shared point of reference for historic Apollo and new robotic and crewed programmes.

Key context

  1. Synchronous rotation means that we normally see the same side of the Moon from Earth.
  2. Apollo samples provided direct material for studying lunar geology.
  3. Lunar orbit is a transfer point for both landing and returning crews.
