PolarCube is a 3U CubeSat based on the ALL-STAR platform and featuring an Earth-sensing passive microwave instrument with suborbital aircraft flight heritage that is currently being miniaturized for an orbital opportunity to provide atmospheric temperature profile measurements and sea ice/ ice-free ocean detection and mapping. This instrument, already prototyped, will be the first passive microwave sensor flown on a small satellite.
