NASA is working to reestablish contact with one of the eight spacecraft that make up its Cyclone Global Navigation Satellite System (CYGNSS) constellation, which monitors hurricanes. CYGNSS is the first space-based system to collect frequent measurements of wind speeds from the ocean's surface near the eye of storms such as tropical cyclones, typhoons and hurricanes. However, the CYGNSS team last received data from the satellite designated FM06 at around 4:32 p.m. EST (2132 GMT) on Nov. 26, according to a NASA statement. The remaining seven satellites that comprise the CYGNSS constellation remain operational and have continued collecting scientific data since FM06 went incommunicado last month, according to NASA's primary statement about the incident. The constellation's science work can continue without FM06, but if the team can't reconnect with the spacecraft, the loss will reduce the spatial coverage of CYGNSS, which until November provided nearly gap-free coverage of Earth.
