Lift-off of the Antares rocket occurred today at 12:52 p.m. (EDT) from the Mid-Atlantic Regional Spaceport’s Pad 0A located NASA’s Wallops Flight Facility in eastern Virginia. Following a 10-minute ascent, the Cygnus spacecraft was successfully deployed and placed into its intended orbit of 120 x 180 miles (190 x 290 kilometers) above the Earth, inclined at 51.6 degrees to the equator. Orbital’s engineering team has confirmed that reliable communications had been established and that the solar arrays are fully deployed, providing the necessary electrical power to command the spacecraft.
The launch of Orbital’s Antares rocket and Cygnus cargo logistics spacecraft will culminate in rendezvous and berthing with the ISS on July 16 at approximately 6:39 a.m. (EDT). Cygnus will deliver 3,669 pounds (1,664 kilograms) of cargo to the Expedition 40 astronauts and remain attached to the station approximately 30 days before departing with approximately 2,950 pounds (1,340 kilograms) of disposable cargo for a safe, destructive reentry over the Pacific Ocean approximately five days later.
