Scientists say parts of the Moon may be set aside as spacecraft graveyards for defunct satellites.
Lunar orbits are expected to fill rapidly as space agencies and companies expand Moon activity.
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 sites and historic landmarks.
Designated impact zones would limit debris and protect sensitive areas.
The European Space Agency and UK Space Agency support planned disposal zones.
Some scientists add controlled impacts could help study the Moon’s internal structure.
