Private space venture Orbital Sciences is preparing for its second official resupply mission to the International Space Station, hoping for a perfect launch from at Wallops Island, Va, after several delays.

The Antares rocket, carrying an unmanned Cygnus resupply capsule packed with 3,293 lbs. of cargo, including food, science experiments and small satellites is scheduled for liftoff from Wallops at 12:52 ET.

At a pre-launch briefing on Saturday, former NASA astronaut and Orbital Sciences CEO Frank Culbertson said the company was “real proud to be part of the team that is keeping the station flying and providing the crew with cargo and research they need.”

By way of background, Space.com says:

“Orbital [Sciences], which is based in Dulles, Virginia, has a $1.9-billion contract with NASA to carry out eight cargo missions through 2016. Elon Musk’s SpaceX, the only other commercial company with a NASA resupply contract, has been commissioned to fly 12 missions to the station under a $1.6 billion deal.

“The mission, dubbed Orb-2, was originally scheduled for May. It had been postponed due to conflicts with other launches and technical issues, including the failure of an AJ26 engine — the kind that powers Antares’ first stage — during a test at NASA’s Stennis Space Center in Mississippi, which prompted an investigation.

“Then this week, the mission was repeatedly delayed because stormy weather prevented Orbital’s launch team from conducting normal operations to get the rocket ready on the pad.”

Antares made its first successful flight in April 2013.
