CUMULOS Achieves First Major Milestone

EL SEGUNDO, Calif., July 3, 2018 – The Aerospace Corporation achieved first light on an infrared sensor suite named CubeSat Multispectral Observing System (CUMULOS).

An impressive view of the Earth centered on Lake Superior was captured by the first CUMULOS short wave infrared camera image on June 11, 2018 exhibiting strong contrast between cloud, water and land features from Ontario across the great lakes to the Earth limb. 

CUMULOS was flown as a secondary payload on the Integrated Solar Array and Reflectarray Antenna (ISARA) CubeSat—a mission managed by NASA’s Jet Propulsion Lab (JPL),  operated by Aerospace, and sponsored by NASA’s Small Spacecraft Technology Program. The CUMULOS is the first infrared sensor flown as part of the corporation's AeroCube program, which allows infrared weather imagery to be studied by the small satellite.

“This is the first infrared imaging sensor payload that we’ve launched on a CubeSat and its successful turn-on and operation is a major milestone for us,” said Dee Pack, principal investigator for the CUMULOS mission and director of Aerospace’s Remote Sensing Department. “We appreciate Caltech’s Jet Propulsion Laboratory and NASA’s Small Spacecraft Technology Program for extending us the opportunity to fly CUMULOS as a secondary payload onboard the ISARA mission.”

CUMULOS was able to fly as a secondary payload on ISARA due to the space-saving reflectarray. Made of three compact cameras with lenses an inch or less in diameter, CUMULOS has a visible wavelength camera, a short-wavelength infrared camera, and a long-wavelength infrared, microbolometer camera.

Designed for weather and Earth environmental monitoring, the CUMULOS cameras can measure surface temperature, detect environmental hotspots, take cloud cover pictures, and provide nighttime lights imaging. 

Aerospace will continue on-orbit checkout for the CUMULOS mission during July 2018 and then commence science mission operations. Its success will lead to the possibility of executing weather forecasting and other Earth observation missions with small satellites in the future.
