WASHINGTON — NASA ordered two more cargo deliveries to the International Space Station from Orbital ATK under a 2008 Commercial Resupply Services (CRS) contract, a company spokeswoman said Aug. 12.

Orbital ATK, Dulles, Virginia, will fly two more missions under its 2008 contract for a total of 10 flights,  according to Orbital ATK spokeswoman Vicki Cox. The company designated the missions OA-9e and OA-10e, Cox said. She declined to say when those flights will occur, although the company has said it plans to launch any new CRS missions it gets from NASA on Antares once it completes two deliveries using United Launch Alliance’s Atlas 5 rocket. The Atlas 5 launches are slated for December and early 2016 from Cape Canaveral, Florida.

NASA may also order additional  cargo flights from its other CRS contractor, SpaceX of Hawthorne, California. "A modification is in work with both [CRS] providers," NASA spokeswoman Stephanie Schierholz wrote in an Aug. 13 email. "Additional missions for SpaceX are still under discussion."

SpaceX spokesman John Taylor referred questions about the company's CRS contract to NASA.

Neither Schierholz nor Cox would disclose the financial terms of NASA's latest CRS orders. The agency signed CRS contracts with Orbital ATK and SpaceX in 2008. Each of these indefinite-quantity, indefinite-delivery deals runs through 2016 and has a maximum value of $3.1 billion. The eight deliveries NASA ordered from Orbital ATK in 2008 cost the agency $1.9 billion. The 12 missions NASA ordered from SpaceX that year cost $1.6 billion.

NASA solicited CRS-2 bids last September and had planned to make awards in May. That slipped to September, and then again to November.

Both Orbital ATK and SpaceX suffered launch failures on their latest delivery attempts to ISS. On what was to be its third CRS mission, Orbital ATK's Antares rocket exploded moments after its Oct. 28 liftoff from the Mid-Atlantic Regional Spaceport at NASA's Wallops Flight Facility in Virginia. SpaceX's Falcon 9, which launches from Cape Canaveral, exploded about two minutes after liftoff June 28 on what was supposed to be its seventh CRS delivery.

Orbital ATK blamed Antares core stage AJ-26 engines, Soviet-vintage hardware refurbished by Aerojet Rocketdyne of Sacramento, California, for the October failure. SpaceX has yet to come up with a root cause for the June 28 Falcon 9 failure but believes a faulty strut in the upper stage contributed to the mishap.
