Andy's Mission

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.

Avionics

The avionics system controls Andy's many subsystems, including its motors, cameras, radios. Andy's avionics were developed here at Carnegie Mellon and are a novel, low cost, radiation-tolerant design; achieved with a clever mix of custom, space-grade parts and cheap, off-the-shelf ones.

User Interface

Andy's user interface is used to send instructions and to monitor its sensors and health. We have to be very careful and certain with our commands, because Andy experiences at least 1.25 seconds of uplink lag due to the speed of light.

Solar Panels

With an effective area of 0.5 m2, the space-rated, triple junction, high efficiency solar panels produce up to around 100 Watts in direct sunlight on the moon. These are Andy's only source of power on the Moon.

Cameras

These two cameras are Andy’s eyes. They send us back a high definition, panoramic, and near real time view of the Moon. Although we can't go there today, Andy will allow us to experience the Moon from the comfort and safety of Earth.
