How long will the footprints on the moon last?

User Avatar
The footprints on the moon will likely be there for as long as the moon is. Unlike Earth, there’s no liquid water, no volcanic activity, and no weather to speak of on the moon, so aside from the occasional meteorite and solar wind (which takes ages to have an effect), there’s nothing on the moon to mess with the footprints. They’re still there—along with spacecraft, scientific equipment, mementos, bags of human waste, and a lot more.
