NASA engineers finished a small science station for the Moon. The device is about the size of a suitcase. Astronauts will place it near the lunar south pole. It will listen for ground movement from moonquakes and meteorite impacts. The station can collect information during very cold lunar nights.
A light, flexible solar panel wraps around the instrument. It is designed to work through the cold lunar night without outside power or heat. NASA tested its parts before saying the hardware was complete. The long project should help researchers understand the Moon's inside. Its results may also support safer science work on the lunar surface.
