CYGNSS Launch Aboard Pegasus XL Rocket Postponed

The planned launch of NASA’s CYGNSS spacecraft aboard an Orbital ATK Pegasus rocket has been postponed. A hydraulic pump aboard the Orbital ATK L-1011 Stargazer aircraft, which is required to release the latches holding Pegasus in place, is not receiving power. Teams will assess the issue after the Stargazer lands at the Cape Canaveral Air Force Station Skid Strip. The next possible launch opportunity is Tuesday, pending resolution of the pump issue. The CYGNSS satellites are designed to make frequent and accurate measurements of ocean surface winds throughout the life cycle of tropical storms and hurricanes.
