NASA to resume ISS supply mission launch today

Orbital Sciences has confirmed it will proceed with a 1:07 p.m. EST launch attempt of the Orbital-1 cargo resupply mission to the International Space Station (ISS) on Thursday, Jan. 9, pending closeout of all remaining pre-launch reviews and tests. Orbital conducted a comprehensive review of data related to the radiation environment in space, further reviews and modeling of the rocket’s avionics systems, and the forecast for favorable terrestrial weather conditions at NASA's Wallops Flight Facility in Wallops Island, Va. As of this evening, weather is 75% go with a 25% chance of weather prohibiting launch. The main concern is thick clouds.

Upon a deeper examination of the current space weather environment, Orbital’s engineering team, in consultation with NASA, has determined that the risk to launch success is within acceptable limits established at the outset of the Antares program. NASA Television coverage of launch will begin at 12:45 p.m. EST. A post-launch news conference would follow at approximately 2:30 p.m. A Thursday launch would result in the Cygnus spacecraft arriving at the ISS on early Sunday, Jan. 12. NASA TV coverage of rendezvous and berthing will begin at 5 a.m. EST for a 6:02 a.m. capture. Coverage of installation of Cygnus will begin at 7:00 a.m. EST.
