Researchers say parts of the Moon will be designated as spacecraft graveyards for defunct satellites.
Lunar orbit is expected to become increasingly crowded as missions, bases, and satellite networks expand.
Unlike Earth, the Moon has no atmosphere to safely burn up old spacecraft.
As a result, many satellites will need to be deliberately crashed into the surface.
Scientists warn uncontrolled impacts could damage historic sites and sensitive instruments.
Designated impact zones would limit debris and protect areas of scientific importance.
More than 400 lunar missions are planned, including projects led by NASA and the European Space Agency.
Space agencies are now working on international rules for safe lunar satellite disposal.
