Antares Status Report 14 April 2013



On Saturday, Orbital conducted the wet dress rehearsal for the Antares rocket in preparation its Test Flight scheduled for later this week on April 17.

Late in the countdown, at about T-16 minutes, the test was halted because the launch team had detected a technical anomaly in the process. Orbital has determined that a secondary pyro valve aboard one of the two first-stage engines used in the propellant chilldown process was not functioning properly.  

A replacement unit will be installed within 24 hours with the goal of maintaining the April 17 launch date.

Orbital will issue additional updates as warranted.
