Assembly and testing of a significantly upgraded version of Orbital ATK’s commercially developed Antares rocket has kicked into high gear and is on target for rebirth – as the clock ticks down towards its ‘Return to Flight’ by approximately mid-2016 from a launch pad at the Mid-Atlantic Regional Spaceport (MARS) in Virginia, company managers told Universe Today during a recent up close media visit to see the actual flight hardware.Mission integration operations are in full swing right now as technicians were actively processing Antares hardware during my visit to Orbital ATK’s Horizontal Integration Facility (HIF) at NASA’s Wallops Flight Facility in December. “We are working on integrating, processing and testing the Antares rocket hardware,” Mike Pinkston, Vice President and General Manager Orbital ATK’s Antares program, told Universe Today in exclusive interviews at NASA Wallops and the Kennedy Space Center.The cavernous Wallops Island HIF facility was filled from end-to-end with a pair of first stage cores, newly upgraded RD-181 first stage engines, a second stage, interstages, payload fairings and other key components slated to launch on the first two Antares missions in the spring and fall of 2016.“We are planning to resume Antares launches in late May or June 2016,” said Pinkston.The currently planned spring 2016 blastoff will be the first for the private Antares rocket since its catastrophic launch failure on Oct. 28, 2014, just seconds after liftoff from Wallops. It was carrying Orbital ATK’s Cygnus cargo freighter on the critical Orb-3 resupply mission for NASA to the International Space Station (ISS). The launch mishap was traced to a failure in the AJ26 first stage engine turbopump.The revamped Antares 230 launch vehicle has been upgraded with a pair of modern new first stage engines, the Russian-built RD-181 fueled by LOX/kerosene. They replace the refurbished 40 year old AJ26 engines originally —> Read More
