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 has no atmosphere to burn up old satellites.
Most dead spacecraft will eventually need controlled crash-landings.
Scientists warn random impacts could damage instruments, historic sites, or pristine terrain.
High-speed collisions create craters, vibrations, and clouds of abrasive dust.
Experts from University of Durham and Birkbeck University of London say planning is essential.
More than 400 lunar missions are expected, including projects led by NASA and the European Space Agency.
Designated impact zones are seen as the most practical solution.
Controlled crashes could even help scientists study the Moon’s internal structure.
