Orbital Set to Launch Company-Built NuSTAR Astrophysics Spacecraft for NASA Aboard Pegasus Rocket

Orbital Sciences Corporation (NYSE: ORB) today announced that it is in final preparations to launch the Nuclear Spectroscopic Telescope Array (NuSTAR) satellite that the company designed, manufactured and tested at its Dulles, VA production facilities. The NuSTAR satellite will be launched aboard Orbital’s Pegasus® air-launched rocket in a mission that will originate from Kwajalein Atoll in the Marshall Islands located near the Equator in the mid-Pacific Ocean. The targeted launch date and time is Wednesday, June 13 at 11:30 a.m. (EDT), subject to final pre-launch preparations and testing activities, as well as acceptable weather conditions at the time of the launch.

Orbital’s The L-1011 “Stargazer” aircraft will depart from the Ronald Reagan Test Facility on Kwajalein Atoll approximately one hour prior to the targeted launch time. Following a pre-planned flight path, the Pegasus rocket will be released at approximately 39,000 feet and first stage ignition will occur approximately five seconds later. The powered flight sequence for the NuSTAR mission is expected to take just over 13 minutes, from the time the Pegasus rocket is released to the time that the satellite is separated from the rocket’s third stage and is deployed into orbit.
