Antares poised on the pad.
Orbital's Antares rocket will launch the Cygnus spacecraft from the Mid-Atlantic Regional Spaceport's Launch Pad 0A at NASA's Wallops Flight Facility in Virginia today at 12:52 p.m. EDT.
Cygnus will carry some 3,300 pounds of cargo to the station, including crew food and supplies, hardware, and scientific equipment and experiments.
Wallops' Weather Office reports that the forecast is 90-percent favorable for Sunday's launch.
NASA Prelaunch Briefing
The prelaunch status of the upcoming Orbital-2 Mission to the International Space Station was discussed during a pre-launch briefing seen on NASA Television.
This and future commercial cargo resupply flights will ensure a robust national capability to deliver critical science research to orbit, significantly increasing NASA's ability to conduct new science investigations to the only laboratory in microgravity.
