CLEARFIELD - ATK, which has Utah operations in Clearfield, Promontory in Box Elder County, and in Salt Lake County, provided second stage propulsion for last week's successful Orbital Sciences Corporations Antares rocket launch.
A press release from ATK noted that the rocket was launched on its first NASA Commercial Resupply Services mission to the International Space Station.
The mission's purpose is to deliver critical supplies on-time to the only laboratory in microgravity.
"ATK's CASTOR second stage motor played an important role in successfully launching Orbital's first CRS mission to the ISS," said Scott Lehr, vice president and general manager of ATK Aerospace GroupÕs Defense and Commercial division.
"CASTOR 30B's greater performance was achieved by making several innovative, cost effective changes to the baseline motor, which provided additional thrust," he said in the press release.
