Designing a compact, self-contained control and power system for a DMD-based spectrograph suitable for the space environment

A NASA-funded technology maturation effort to develop multi-object spectroscopy in space will be performed with a digital micromirror device (DMD) on the Spectroscopic Ultraviolet Multi-object Observatory (SUMO) Prototype. It will be the first DMD-based instrument to operate in space as a secondary payload on the CU Boulder sounding rocket INFUSE. The SUMO Prototype consists of: a DMD manufactured by Texas Instruments, an off-the-shelf camera for the imaging channel, a custom NUV CCD camera developed in-house at the Laboratory for Atmospheric and Space Physics (LASP) for the spectral channel, a Raspberry Pi for the flight computer, a controller for the DMD, and an electrical power system (EPS) with a rechargeable battery. The SUMO Prototype is nominally scheduled for flight in the Spring of 2025.
