More lunar missions means more space junk around the Moon – two scientists are building a catalog to track the trash

With more than 100 lunar missions planned in coming years, space junk near the Moon could become an issue for humanity. No agency tracks lunar space junk, so two astronomers decided to do it themselves.

If a satellite falls on your house, space law protects you – but there are no legal penalties for leaving junk in orbit

Chances are small that space junk will destroy property or harm a person, and existing space law could deal with such an event. But current law doesn't address the bigger problem of space pollution.
