The three-stage, all-solid-fueled Orbital ATK Pegasus XL rocket is the only airborne, commercially developed launch vehicle. At 55 feet long, if stood on its end it would be about half the height of the Statue of Liberty. Its 39,000-foot deployment altitude is 10,000 feet higher than Mount Everest, the highest point on Earth – and …
CYGNSS will utilize a constellation of eight microsatellite observatories that will be placed in a circular orbit more than 316 miles above the Earth's surface. With an orbital inclination of 35 degrees, the small spacecraft will concentrate on the region nearest the equator — the tropics — where these cyclones form. The mission will measure …
NASA's Cyclone Global Navigation Satellite System mission, or CYGNSS, is scheduled to begin this morning with launch aboard an Orbital ATK Pegasus XL rocket at 8:35 a.m. EST. The one-hour launch window extends until 9:21 a.m. Forecasters with the U.S. Air Force 45th Weather Squadron predict a 90 percent chance of favorable conditions at launch …
Today's launch of NASA's CYGNSS spacecraft aboard an Orbital ATK Pegasus XL rocket now is scheduled for 8:35 a.m. EST. The launch window extends to 9:21 a.m. The weather outlook has improved to a 90 percent chance of favorable conditions at launch time, with cumulus clouds the primary concern. Weather currently is "green" on all Eastern Range …
NASA managers have given a GO for the next attempt to launch of the agency's Cyclone Global Navigation Satellite System (CYGNSS) mission now scheduled for Thursday at 8:26 a.m. EST. Mission personnel uploaded new flight parameter data to the CYGNSS spacecraft this morning, correcting an issue discovered during routine testing on Tuesday. There is no …
NASA's CYGNSS mission has been rescheduled for launch Thursday, Dec. 15 at 8:26 a.m. EST. The forecast calls for an 80 percent chance of acceptable conditions during the 1-hour launch window. Mission personnel uploaded new flight parameter data to the CYGNSS spacecraft this morning, correcting an issue discovered during routine testing on Tuesday. The launch …
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 …
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 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 …
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 …
