Miniaturizing technology to study spectral irradiance
The Compact Spectral Irradiance Monitor (CSIM) is a 6U CubeSat launched in late 2018 and decommissioned in February 2022. It will demonstrate next-generation technology for monitoring spectral solar irradiance. CSIM is a two-channel 6U CubeSat that includes a miniaturized version of the SIM instrument that flew on both SORCE and TSIS missions. It is designed to measure the solar spectral irradiance twice a day with amazing accuracy. The key detector that enables this level of accuracy, a vertically-aligned carbon nanotube electrical substitution radiometer, was developed jointly with the Sources and Detectors Group at NIST Boulder.
