NASA, Orbital ATK and United Launch Alliance (ULA) have postponed Orbital ATK’s seventh commercial resupply services mission to the International Space Station. ULA discovered a new booster hydraulic issue during prelaunch testing. The ULA team is developing a plan to resolve the issue and a new launch date will be determined.
Orbital ATK has contracted with ULA for its Atlas V rocket for the launch service, which will lift off from Cape Canaveral Air Force Station in Florida. Orbital ATK’s Cygnus cargo spacecraft is packed with 7,600 pounds of supplies and research for crew aboard the orbiting laboratory. The Atlas V and Cygnus remain secure.
