urn:nasa:pds:psyche.grs:data_raw 3.0 1.22.0.0 Product_Collection 2026 Psyche Gamma Ray Spectrometer GRS This data collection contains the raw spectrometer and engineering products returned by the Gamma Ray Spectrometer (GRS) instrument flown aboard the Psyche spacecraft of NASA's Psyche mission. These data products are formatted as binary tables of time series data. The Psyche mission is a planetary mission to investigate the Psyche asteroid and accomplish several scientific objectives, among them determining whether the asteroid is the exposed core of a proto-planetary body.
