-- Company to Carry Out Dual Mission as Both Satellite Manufacturer and Launch Services Provider in Support of NASA’s Astrophysics Satellite Programs --
-- Launch to Originate from Kwajalein Atoll in the Mid-Pacific Region Near the Equator --
(Dulles, VA 12 June 2012) -- 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.
About the NuSTAR Mission
The NuSTAR satellite project is led by Dr. Fiona Harrison, the mission’s Principal Investigator from the California Institute of Technology (Caltech). It is part of NASA’s Small Explorer (SMEX) series that is managed by the Goddard Space Flight Center for NASA’s Science Mission Directorate. These low-cost, highly effective small satellite missions have enabled scientists to gather critical data about the Earth’s environment, the solar system and beyond. In addition to Caltech, NASA’s Jet Propulsion Laboratory (JPL) is one of Orbital’s key mission partners on the NuSTAR project.
During its mission, NuSTAR will use high-energy x-rays to detect black holes and other energetic phenomena in the universe with the purpose of expanding our understanding of the origins and destinies of stars and galaxies. NuSTAR will have more than one hundred times the sensitivity of previous instruments to detect black holes and will be the first focusing hard x-ray telescope in space.
For the NuSTAR mission, Orbital is providing the LEOStar-2 spacecraft platform, performing overall system integration, and conducting the launch operations with its Pegasus air-launched rocket, a comprehensive mission support combination that it has previously carried out for numerous successful NASA scientific missions such as the SORCE, GALEX, AIM and IBEX projects.
About the Pegasus Rocket
Pegasus is the world’s leading launch system for the deployment of small satellites into low-Earth orbit. Its patented air-launch system, in which the rocket is launched from beneath Orbital’s “Stargazer” L-1011 carrier aircraft over the ocean, reduces cost and provides customers with unparalleled flexibility to operate from virtually anywhere on Earth with minimal ground support requirements. The NuSTAR launch from Kwajalein is an example of its unrivaled mission versatility. The launch of the NuSTAR satellite will be the 41st Pegasus mission since its introduction in 1990. It remains the world’s only small space launch vehicle that is certified with NASA’s Payload Risk Category 3, which the space agency reserves for its highest value space missions.
Orbital develops and manufactures small- and medium-class rockets and space systems for commercial, military and civil government customers. The company’s primary products are satellites and launch vehicles, including low-Earth orbit, geosynchronous-Earth orbit and planetary spacecraft for communications, remote sensing, scientific and defense missions; human-rated space systems for Earth-orbit, lunar and other missions; ground- and air-launched rockets that deliver satellites into orbit; and missile defense systems that are used as interceptor and target vehicles. Orbital also provides satellite subsystems and space-related technical services to government agencies and laboratories.
