NASA has awarded $3 million to a team of five University of Hawaiʻi at Mānoa scientists in support of a system that will search for widespread ice deposits beneath the lunar surface. The mission, called the Cosmic Ray Lunar Sounder (CoRaLS), aims to be the first to find ice more than a meter underground by analyzing the refracted radio signals of cosmic ray particles striking the surface of the Moon.
