When a stream of charged particles known as the solar wind careens into the Moon’s surface at nearly 280 miles per second (450 kilometers per second), it enriches the Moon’s surface in ingredients that could make water. In the experiment shown in this video, planetary scientists from NASA’s Goddard Space Flight Center test how this process works and the chemical signatures it leaves behind.
