Scientists say parts of the Moon will be set aside as graveyards for dead satellites.
Lunar orbits are expected to fill rapidly as space agencies expand Moon missions.
Unlike Earth, the Moon lacks an atmosphere to safely burn up old spacecraft.
As a result, many satellites will need to be deliberately crash-landed.
Researchers warn uncontrolled impacts could damage scientific equipment and historic sites.
Designated impact zones would limit debris and protect sensitive regions.
International agencies are working on rules for safe lunar satellite disposal.
