NASA’s Mars Orbiter Launch Delayed 24 Hours

The launch of NASA’s Mars Reconnaissance Orbiter (MRO) has been postponed. The new launch window is 7:43 to 9:43 a.m. EDT, Friday, August 12.

The delay was called after engineers saw an anomalous reading in the hydrogen propellant loading system on the Atlas V. There was insufficient time in the launch window to fully investigate the reading. The Atlas V vehicle is being de-tanked. The rocket will remain on the launch pad, and the MRO spacecraft is secured.

Tomorrow’s weather forecast calls for a chance for isolated coastal showers. There is a 20 percent probability of not meeting the launch weather criteria.

On launch day, August 12, the KSC News Center will open at 4:30 a.m. EDT. Foreign national news media should meet at Gate 1 at Cape Canaveral Air Force Station at 5 a.m. to be escorted to the KSC Press Site. NASA TV live coverage of the launch begins at 5:15 a.m. EDT.
