Psyche’s Spectrometer

Engineers at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, continue to make progress on Psyche’s spectrometer while observing COVID-19 safety procedures. Engineers John Goldsten (left) and Sam Fix work on the Gamma-Ray/Neutron Spectrometer (GRNS) instrument that will launch aboard the Psyche spacecraft in 2022 to detect, measure and map the asteroid Psyche’s elemental composition. The instrument’s team at APL moved the majority of its work to video conferencing, which has enabled the team to whittle operations down to requiring just one or two staff members on campus once or twice a week.

Arizona State University leads the Psyche mission. NASA’s Jet Propulsion Laboratory in Southern California is responsible for the mission’s overall management, system engineering, integration and test, and mission operations. Maxar Technologies is providing a high-power solar electric propulsion spacecraft chassis. For more information about NASA’s Psyche mission go to: or
