Targeted observations of atmospheric trace gases at high spatial resolution are important for characterizing the sources, distribution, and evolution of anthropogenic pollution. The Compact Hyperspectral Air Pollution Sensor (CHAPS) is an imaging spectrometer designed for a 6U CubeSat to fill this need. Miniaturization of this instrument was enabled through the use of freeform optics, additive manufacturing (AM), and topology optimization (TO). We developed the CHAPS–Demonstrator (CHAPS-D) with support from NASA’s Earth Science Technology Office and will demonstrate the feasibility of AM and TO in reducing volume and mass while advancing its technology readiness level (TRL) for future space instrument applications.
