Orbital Science Corp.’s Antares rocket and Cygnus cargo spacecraft will launch from the Mid-Atlantic Spaceport’s Pad 0A at NASA’s Wallops Flight Facility in Virginia.

Live launch coverage is currently airing on NASA TV.

The launch of Orbital’s CRS-3 Commercial Resupply Services mission is the third commercial resupply flight by a Cygnus spacecraft to the International Space Station, and the first night launch of an Antares rocket. Cygnus will transport some 5,000 pounds of supplies and experiments to the orbiting laboratory.

The rocket is scheduled to roll out to Mid-Atlantic Regaional Spaceport Pad 0A at Wallops late in the afternoon on Oct. 24 in preparation for launch Monday, Oct. 27, at 6:45 p.m. EDT.

This mission is the third of eight Orbital flights NASA contracted with the company to resupply the space station, and the fourth trip by a Cygnus spacecraft to the ISS. Cygnus will transport some 5,000 pounds of supplies and experiments to the orbiting laboratory.

The Antares rocket with Cyngus capsule aboard will be rolled out from Wallops’ Horizontal Integration Facility today en route to the MARS launch pad 0A, located about a mile away.

This Cygnus resupply module, dubbed “SS Deke Slayton,” honors Mercury 7 astronaut Donald “Deke” K. Slayton, who flew on the Apollo-Soyuz Test Project mission in 1975 and championed commercial space endeavors after retiring from NASA in 1982. Slayton passed away in 1993.

NASA Television will broadcast live coverage of the event, including pre- and post-launch briefings and arrival at the station. Launch coverage begins at 5:45 p.m. Monday. Coverage of capture and installation will begin at 3:30 a.m. Nov. 2, followed by grapple at 4:58 a.m. Coverage of the installation of Cygnus onto the International Space Station will begin at 7 a.m. The capsule is scheduled to depart the station Wednesday, Dec. 3, and burn up in Earth’s atmosphere during reentry.

This mission is the third of eight Orbital flights NASA contracted with the company to resupply the space station, and the fourth trip by a Cygnus spacecraft to the orbiting laboratory.
