Psyche gamma-ray instrument hums to life, marking next generation for space exploration

Set 6.5 feet (2 meters) away from NASA's Psyche spacecraft on the tip of a boom, the mission's gamma-ray spectrometer (GRS) hummed to life on Nov. 6 for the first time since launch in mid-October. The GRS is one half of the Gamma-Ray and Neutron Spectrometer (GRNS) instrument on the Psyche mission.
