Researchers say parts of the Moon will be set aside as spacecraft graveyards for defunct satellites.
Lunar orbits are expected to fill rapidly as space agencies plan bases, mining, and science missions.
Unlike Earth, the Moon lacks an atmosphere, leaving crash-landings as the main disposal option.
Uncontrolled impacts could damage historic sites, instruments, and sensitive scientific locations.
Experts from University of Durham and Birkbeck, University of London warn planning is needed now.
More than 400 Moon missions are planned, including projects led by NASA and the European Space Agency.
Designated impact zones or deep craters are seen as the safest solution.
Controlled crashes could also help scientists study the Moon’s internal structure.
