Our Growing, Shrinking Moon New images from NASA suggests our moon is growing as well as shrinking. We often think of the moon as a geologically dead fixture in our sky. That isn’t a bad thing; scientists have long looked at the moon a perfectly preserved slice of our solar system’s history. But new images returned from NASA’s Lunar Reconnaissance Orbiter (LRO) suggest that our natural satellite isn’t dead at all.

The first evidence of an active moon came in 2010 when LRO’s camera returned high resolution pictures of landforms called lobate scarps.
