Orbital Begins Antares Rocket Operations at Mid-Atlantic Regional Spaceport

Orbital Sciences Corporation, one of the world's leading space technology companies, today announced that it has commenced Antares launch vehicle operations at the liquid-fuel launch complex at the Mid-Atlantic Regional Spaceport (MARS). Following a four-year design, development, construction, test and inspection process, the Virginia Commercial Space Flight Authority (VCSFA), which oversees MARS, has authorised Orbital to begin on-pad operations leading up to flight demonstrations of its Antares medium-class launch vehicle and Cygnus cargo logistics spacecraft, the vehicles Orbital will use to fulfil a $1.9 billion NASA contract to deliver essential cargo to the International Space Station (ISS). The MARS launch complex is located at NASA's Wallops Flight Facility in eastern Virginia and is owned and operated by MARS, under the auspices of the VCSFA, which receives its funding from the Commonwealth of Virginia.

NASA Wallops set to launch its biggest rocket

Virginia's "Space Coast" ambitions are getting a big boost as NASA's Wallops Flight Facility on the Eastern Shore prepares to launch the biggest rocket in its 67-year history.
Called the Antares, the rocket is expected to become a workhorse in the commercial space industry over the next several years, ferrying cargo to the International Space Station.

Orbital's Antares Medium-Class Launch Vehicle On-Ramped to NASA's NLS-II Program

Orbital Sciences Corporation today announced that it has successfully completed contract negotiations with the National Aeronautics and Space Administration (NASA) to "on-ramp" its Antares medium-class launch vehicle onto the NASA Launch Services-II (NLS-II) program. The NLS program is a contracting mechanism that allows NASA to procure qualified launch vehicles that have completed stringent technical and pricing reviews. The Antares rocket joins other Orbital launch vehicles, as well as those from other launch services providers, on the NLS program. Under the NLS program and other contracts, Orbital rockets have carried out 27 successful missions for NASA since 1996, including the recent successful launch of Orbital's small-class Pegasus rocket, which carried the company-built Nuclear Spectroscopic Telescope Array (NuSTAR) satellite into orbit earlier this month.

Orbital Successfully Test Fires First Stage Rocket Engine for Taurus II Rocket

Orbital Sciences Corporation, one of the world's leading space technology companies, today announced the successful test firing of the liquid fuel AJ26 engine that will power the first stage of the company's TaurusŪ II space launch vehicle. In a test conducted yesterday at NASA's Stennis Space Centre in Mississippi, Orbital and its engine supplier Aerojet, a unit of GenCorp, test fired an AJ26 engine at the E-1 test stand. The E-1 test stand was refurbished by Stennis over the past year specifically for Orbital's Taurus II program. The AJ26 test firings at Stennis are being conducted to verify the upgrades made by Orbital and Aerojet to the baseline NK-33 engine and overall engine performance in its final flight configuration.

Taurus II is a two-stage launch vehicle designed to provide responsive, low-cost, and reliable access to space for medium-class payloads weighing up to 5750 kg. Currently under development to demonstrate commercial re-supply of the International Space Station under a NASA Commercial Orbital Transportation Services (COTS) contract, the Taurus II launch system utilises identical management approaches, engineering standards, production and test processes common to Orbital's family of highly successful small-class PegasusŪ, TaurusŪ, and Minotaur launch vehicles.
