Monday’s Antares rocket launch will mark Orbital Sciences’ third official cargo mission to the International Space Station for NASA under a $1.9 billion contract, which calls for a total of eight delivery missions. The mission, called Orb-3, will launch a robotic Cygnus spacecraft – also built by Orbital – that is filled with 5,000 lbs. of food, water, experiments and other gear for the astronauts currently living aboard the space station.
UPDATE for Monday, 6:53 pm ET: A stray boat in the launch range forced Orbital Sciences to postpone Monday’s Antares rocket launch. The launch is now set for Tuesday, Oct. 28, at 6:22 p.m. EDT, with NASA’s live webcast to begin at 5:30 p.m. EDT.
