Launch day everyone! The launch window has been shortened to 1700-1900 UT. Weather doesn't look promising, broken clouds at 4,000 feet - everything else looks fine though. Tomorrow will feature less clouds, but with an increase in winds.
Statement Regarding the Antares Launch Postponment
April 2013
Orbital announced that a premature separation of a launch pad umbilical connection to the Antares upper stage used for data communications halted today's countdown of the Antares test launch at the Mid-Atlantic Regional Spaceport at NASA's Wallops Flight Facility on Wallops Island, Va. Engineers are currently analyzing what occurred to determine what measures will be taken to resolve the issue.
During a launch countdown, safeguards are put in place to periodically verify that all systems are functioning as planned. With twelve minutes left in the count, the launch team identified the anomaly and called a scrub of today's test launch attempt.
The next launch attempt is tentatively set for no earlier than Friday, April 19, pending final resolution of the issue and acceptable weather conditions.
"We are still examining all of the data, but it appears that the issue is fairly straightforward," said Mr. Frank Culbertson, Orbital's Executive Vice President and Mission Director for the Antares Test Flight. "With this being the first launch of the new system from a new launch facility we have taken prudent steps to ensure a safe and successful outcome. Today, our scrub procedures were exercised and worked as planned. We are looking forward to a successful launch on Friday."
