Lockheed Martin and United Launch Alliance Statement about Launch Scrub
Cape Canaveral Air Force Station, Fla., Dec. 4, 2014 - The launch of the United Launch Alliance Delta IV Heavy rocket carrying NASA’s Orion spacecraft for Lockheed Martin was scrubbed today when, after an extended hold for ground wind conditions, the liquid hydrogen fill and drain valves on both the port and center common booster cores did not properly close within the allotted time. The Orion spacecraft has no technical or operational issues and remains ready for launch.
Pending resolution of troubleshooting, the next launch is scheduled for Friday, Dec. 5 from Space Launch Complex-37 at Cape Canaveral Air Force Station, Florida. The launch window on Dec. 5 would open at 7:05 a.m. EST and remain open for two hours and 39 minutes. The forecast for Dec. 5 shows a 40 percent chance of favorable weather conditions for the launch tomorrow.
