Abstract

The Star-Planet Activity Research CubeSat (SPARCS) will be a 6U CubeSat whose mission will be to observe M stars in two ultraviolet (UV) bands—SPARCS far UV (S-FUV: 153-171 nm) and SPARCS near UV (S-NUV: 260-300 nm). SPARCS would be the first mission to provide time-dependent spectral slope, intensity and evolution of M dwarf stellar radiation; measurements that are critical to deciphering observations of planetary atmosphere from missions such as JWST. The baseline UV camera for SPARCS (SPARCam) includes the electronics boards and two UV detectors, one optimized for each of the SPARCS bands. The camera’s low-noise electronics are based on JPL’s compact, modular design and provide dynamic observation capabilities. For its detectors, SPARCam uses 2D-doped (i.e. delta-doped) CCDs for both channels. Here we present SPARCam development and characterization results prior to payload integration. Copyright 2019.
