Gamma-Ray Spectrometer
Images of the Psyche Gamma-Ray Spectrometer flight unit lid with its “special part number,” next to the fully-built engineering test unit. This gamma-ray spectrometer was adapted for space flight from terrestrial designs that have been developed by researchers at Lawrence Livermore National Labs (LLNL) over the past two decades. The part number contains the initials of the engineers, scientists, and technicians that worked closely on the design of the instrument. The meteorite pictured in one of the photos is a slice of Muonionalusta, an iron IVA meteorite with an elemental composition relatively similar to something we might find on (16) Psyche.
