Launch managers now are targeting the drop and launch of the Orbital ATK Pegasus XL rocket with NASA's CYGNSS spacecraft for 8:40 a.m. EST. The L-1011's anticipated departure time is now 7:37 a.m., allowing time for the pilot to navigate around some precipitation on the way to the drop point. This adjusted timeline keeps NASA …
Fog Situation Beginning to Improve

Now that the sun has risen, the fog already has lifted to a half-mile of visibility at the Skid Strip runway at Cape Canaveral Air Force Station and in other areas has improved a bit beyond that, according to NASA Launch Commentator George Diller. The L-1011's engines are being powered on and we're standing by …
Ground Fog May Delay Takeoff

At the Skid Strip runway at Cape Canaveral Air Force Station in Florida, the Stargazer aircraft and a NASA F-18 chase plane provided by the agency's Armstrong Flight Research Center in California are preparing for takeoff.

A Day of CYGNSS Activities

It is L-2 days here in Florida for NASA's CYGNSS mission and there are several events scheduled that can be seen on social media and NASA TV this afternoon. We've also released a pair of launch preview videos which you can see at the bottom or on Kennedy's YouTube page. The CYGNSS mission is to …
The Winged Pegasus: An Unusual Launch Experience

Orbital ATK's Pegasus rocket gets its payloads into space just like a conventional rocket, but instead of lifting off from the ground, the Pegasus starts its trip already in the air. That's because a modified L-1011 airliner carries the Pegasus and its payload – CYGNSS in this case – to about 39,000 feet. Pegasus begins …
Forecast Worsens to 40 Percent ‘Go’

A revised forecast from the U.S. Air Force 45th Weather Squadron predicts deteriorating conditions and a 40 percent chance of favorable weather for the launch of NASA's CYGNSS spacecraft. Launch is scheduled for 8:24 a.m. EST Monday, Dec. 12 aboard an Orbital Sciences ATK air-launched Pegasus XL launch vhicle, seen on the right beneath the L-1011 …
