CYGNSS rockets into orbit atop Pegasus

The first Cygnus launch from Cape Canaveral in nearly 10 years successfully placed NASA’s eight CYGNSS satellite into orbits Thursday, December 15. Pegasus, attached to the belly of Orbital ATK’s L-1011 Stargazer aircraft, lifted off from Cape Canaveral Air Force Station’s Skid Strip runway at 7:38am EDT.  After reaching an altitude of 39,000 feet and within the 10 by 40 mile launch box, Pegasus was commanded for release, falling away from the mothership at 8:37am. Less than five seconds later, the first stage ignited, beginning a 14-minute climb to orbit for Pegasus and the eight CYGNSS satellites. 

CYGNSS, short for Cyclone Global Navigation Satellite System, will use high-fidelity GPS signals to help forecasters better measure and predict hurricanes. In honor of the storm recently affecting the space coast, the Pegasus rocket launching CYGNSS was named Matthew. This was the 43rd launch of the Pegasus rocket, which made history in 1990 as the world’s first successfully-launched commercially-developed rocket vehicle. It remains the only air-launched rocket system in operation. CYGNSS was originally scheduled for launch Monday, but a faulty hydraulic pump in the rocket’s release mechanism promoted a delay into today. P/C: NASA.
