NASA to Study the Moon’s Interior

As part of the Artemis program, NASA is developing a series of increasingly complex missions to ultimately build a sustained human presence at the Moon for decades to come. Firefly's Blue Ghost Lander will head to the Moon's Mare Crisium for a 14-day lunar lander mission to help understand the Moon’s subsurface in a previously unexplored location.
The Lunar Magnetotelluric Sounder (LMS) will probe the interior of the Moon to depths of up to 700 miles or two-thirds of the lunar radius. The measurements will shed light on the differentiation and thermal history of our Moon, a cornerstone to understanding the evolution of solid worlds.

LMS was funded and delivered to the lunar surface through NASA’s Commercial Lunar Payload Services (CLPS) initiative. Southwest Research Institute built the central electronics and leads the science investigation. Goddard Space Flight Center provided the LMS magnetometer to measure the magnetic fields, and Heliospace Corp. provided the electrodes used to measure the electrical fields.
