The CYGNSS launch planned for Wednesday, Dec. 14 is being delayed due to an issue with flight parameter data used by spacecraft software. The issue was discovered during routine testing Tuesday. The new flight parameter data have undergone verification testing on the engineering model, and will be uploaded to the spacecraft on Wednesday. The uploading …
Weather Improves to 90 Percent ‘Go’ for Wednesday Launch
Meteorologists with the U.S. Air Force 45th Weather Squadron are predicting a 90 percent chance of favorable weather for the launch of NASA's Cyclone Global Navigation Satellite System (CYGNSS) mission, scheduled for Wednesday at 8:25 a.m. EST. The one-hour launch window opens at 8:20 a.m. The CYGNSS spacecraft will ride into orbit aboard an Orbital …
NASA Targets Wednesday for CYGNSS Launch
NASA is rescheduling the launch of its CYGNSS spacecraft for no earlier than Wednesday, Dec. 14, from Cape Canaveral Air Force Station in Florida, during a one-hour window that opens at 8:20 a.m. EST. Live launch commentary will begin at 7 a.m. from nearby NASA Kennedy Space Center, and carried live on NASA Television and …
‘Valiant Troubleshooting in the Air’
NASA Launch Manager Tim Dunn of the Launch Services Program recapped today's launch attempt. The hydraulic system problem developed en route, after takeoff, in the last 25 minutes prior to the initial 8:30 a.m. launch time. The hydraulic system in question was not for the L-1011 aircraft itself, but for the system that allows the Pegasus …
‘Return to Base’ Expected at 9:27 a.m. Eastern
The L-1011 is headed back to the Skid Strip runway at Cape Canaveral Air Force Station in Florida with an expected arrival time of 9:27 a.m. EST.
CYGNSS Launch Scrubbed for Today
Today's launch of NASA's CYGNSS spacecraft has been scrubbed due to problems with the hydraulic pump that controls the release of the Orbital ATK Pegasus XL rocket from the L-1011 carrier aircraft. A hydraulic pump aboard the Orbital ATK L-1011 airplane, which is required to release the latches holding Pegasus in place, is not receiving …
Countdown Continues; Weather Currently ‘Green’
The launch team's strategy, according to NASA Launch Manager Tim Dunn, is to continue down to the L-4 minute mark. If the hydraulic pump is not functioning property at that point, the team will not continue the countdown. Although there are some new storm cells that could begin affecting the flight path in the next …
L-1011 ‘Go’ to Recycle for Next Attempt; Troubleshooting Continues
The Stargazer L-1011 is flying west now in its racetrack pattern in order to set up for a second launch attempt at 9:05 a.m. EST. Meanwhile, the team continues troubleshooting a problem with the hydraulic system that controls the release of the Pegasus XL rocket from the aircraft.
New Launch Time: 9:05 a.m. Eastern
Should a second launch attempt be approved for today, the drop time would be 9:05 a.m. EST for release and launch of the Pegasus XL rocket carrying NASA's CYGNSS spacecraft.
