Kurt Eberly, who helps lead the Antares rocket program at Orbital ATK, recently spoke with Spaceflight Now about the launcher’s return-to-flight with newly-built engines later this year.

A United Launch Alliance Atlas 5 rocket, flying in its basic two-stage configuration with no strap-on solids, was stacked aboard a mobile launch platform at Cape Canaveral’s Vertical Integration Facility on Feb. 22 and 23 in preparation to send Orbital ATK’s S.S. John Glenn cargo ship into orbit for the International Space Station.

SpaceX scrubbed a launch Thursday to investigate a “tiny glitch” in an upper stage engine actuator on the company’s Falcon 9 rocket, delaying liftoff from Florida of a Thai communications satellite at least 24 hours.
