[b]Orbital pressing ahead after issue halts countdown rehearsal[/b] On Saturday (April 13), Orbital Sciences conducted a "wet dress rehearsal" in preparation for its Antares A-ONE test flight scheduled for launch from NASA's Wallops Flight Facility in Virginia on April 17. "Late in the countdown, at about T-16 minutes, the test was halted because a technical anomaly was detected," the company reported. The launch team has since determined that a secondary pyro valve in one of the two first-stage engines was not functioning properly. The valve is used during the propellant chilldown process. Orbital plans to install a replacement valve unit within 24 hours with the goal of maintaining their planned April 17 launch date.
