NASA, Orbital ATK and United Launch Alliance (ULA) are now targeting April 18 for the launch of Orbital ATK’s seventh contracted commercial resupply services mission to the International Space Station. ULA has developed a plan to resolve an earlier booster hydraulic issue, and is moving forward with launch vehicle processing. Both the Atlas V rocket and Cygnus spacecraft remain secure. Several tons of cargo including crew supplies and science experiments packed aboard Cygnus remain in good shape.
