AIR & SPACE MAGAZINE The World’s Newest Rocket Orbital Sciences debuts the mid-size Antares to deliver cargo to the space station. Scott Andrews April 22, 2013 (Wallops Island, VA 21 April 2013) – Orbital Sciences Corporation Antares rocket lifts off for it's first flight from Mid-Atlantic Regional Spaceport (MARS) located at NASA’s Wallops Flight Facility in eastern Virginia. Lift-off took place at 5:00 p.m. (EDT) followed by payload separation approximately 10 minutes after launch. The mission was completed about 18 minutes after launch, once the rocket’s upper stage completed planned maneuvers to distance itself from the payload. The test flight demonstrated all operational aspects of the new Antares launcher, including the ascent to space and accurate delivery of a simulated payload to a target orbit of approximately 150 by 160 miles, with an inclination of 51.6 degrees, the same launch profile it will use for Orbital’s upcoming cargo supply missions to the International Space Station (ISS) for NASA.
