The launch of NASA’s Cyclone Global Navigation Satellite System (CYGNSS) spacecraft is scheduled for 8:24 a.m. EST Monday, Dec. 12. News briefings, live launch commentary, photo opportunities and other media events will be held at nearby NASA Kennedy Space Center in Florida, and carried live on NASA Television and the agency’s website.
During the one-hour window, which opens at 8:19 a.m., CYGNSS will take off aboard an Orbital Sciences ATK air-launched Pegasus XL launch vehicle. The rocket is scheduled for deployment over the Atlantic Ocean from Orbital’s L-1011 carrier aircraft.
CYGNSS will make frequent and accurate measurements of ocean surface winds throughout the lifecycle of tropical storms and hurricanes. The CYGNSS constellation consists of eight microsatellite observatories that will measure surface winds in and near a hurricane’s inner core, including regions beneath the eyewall and intense inner rainbands that previously could not be measured from space.
