Q&A with Kurt Eberly, Orbital ATK’s Antares deputy program manager

Repair crews in Virginia have restored the Antares booster’s launch pad — damaged in an explosive rocket crash nearly one year ago — to flight-ready status as the Orbital ATK launcher moves toward a return-to-flight in 2016.

A 154-foot-long solid rocket booster will be ignited for two minutes Tuesday at a remote test site in Utah, wrapping up a series of five ground firings to prove the motor’s readiness for flight on NASA’s Space Launch System.

A typhoon forecast to move near a ground station in Guam on Monday has forced officials to postpone the launch of a Japanese HTV cargo ship loaded with more than 13,000 pounds of supplies, experiments and a replacement set of batteries for the International Space Station.
