Almost two years after its first version of Antares exploded on launch, Orbital ATK returned to flight at the Mid-Atlantic Spaceport with the launch last night of the company's Cygnus cargo ship to the International Space Station.
The Orbital OA-5 mission was the first launch of the remodeled Antares booster. The original Antares used refurbished Soviet-era engines. The new version uses Russian RD-181 engines, a variant of the RD-180 used by the United Launch Alliance Atlas V.
After the October 28, 2014 accident, Orbital contracted with ULA to launch the Cygnus atop the Atlas V on two missions from Cape Canaveral Air Force Station, so as to honor their delivery contract with NASA.
