The Moon is Still Shrinking as it Cools. That Could Create a Hazard for Lunar Mission.
The Moon is still alive in a geological sense, and that's the part I love. We think of it as a dead rock, but these scarps show it's still settling, still flexing. The shrinkage is tiny, fractions of a meter over millions of years, but the landslides it could trigger are a real problem for anyone trying to build a base camp.
I'd want to know where the scarps sit relative to the proposed landing sites. The study maps these faults, but hazard assessment is different from discovery. If we're going to put humans down near the south pole, we need to know whether the ground will stay put.
This connects to a bigger truth about how little we understand our nearest neighbor. Every time we look closer, the Moon reveals itself as something more complicated than the static relic we assumed. That's the wonder of it, and also the caution.
