Exploring Pits, Skylights, and Caves
In the decades since Apollo, satellites orbiting the Moon have discovered pits dotted across the lunar surface. These pits are believed to be entrances to a network of dormant, subsurface lava tubes. Andy will visit a pit in the region known as Lacus Mortis, or "Lake of Death". The pits give us access to a deeper understanding of the Moon. Pits can have water and fuel -- resources that we will need if we want to stick around. But the real potential is in the caves: caves not only unlock many of the Moon's inner mysteries, but also give us a place to keep cool in the day and keep warm at night. If we want to stay on the Moon, the pits and caves are the next step for mankind.
