(Wallops Island, VA 08 January 2014) - Following 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 the Wallops Island launch facility, the Antares launch team has decided to proceed forward with a launch attempt of the Orbital-1 CRS mission to the International Space Station tomorrow, January 9, pending the close out of all remaining overnight reviews and tests. 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.
Tomorrow's target launch time is 1:07 p.m. (EST), which would allow the Cygnus spacecraft to rendezvous and berth with the International Space Station early Sunday morning, January 12.
