Orbital ATK conducts test of Antares first stage

Orbital ATK (NYSE: OA) has conducted a full-power, hot fire test of the upgraded first stage propulsion system of its Antares medium-class rocket using new RD-181 main engines today at NASA´s Wallops flight facility, the company said.

The 30-second test took place May 31, 2016 at Virginia Space´s Mid-Atlantic Regional Spaceport (MARS) Pad 0A. The Antares engineering team will review test data over the next several days to confirm that all test parameters were met. Assuming the success of the test is confirmed, it will clear the way for the resumption of Orbital ATK´s cargo logistics missions to the International Space Station (ISS) from Wallops Island, Virginia, currently scheduled for July.

The primary goal of the test was to verify the functionality of the integrated first stage, including new engines, modified Stage 1 core, avionics, thrust vector control and pad fueling systems in an operational environment.
