Q&A with Mark Sirangelo, leader of Sierra Nevada Space Systems

An automated SpaceX supply ship parachuted into the Pacific Ocean on Saturday, bringing more than 3,800 pounds of cargo — including a NASA robot requiring repair — back to Earth after a month-long mission at the International Space Station.

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 Falcon 9 rocket fired into a late-night sky Friday night over Cape Canaveral with a Dragon supply ship bound for the International Space Station. Eight minutes later, the booster returned to Florida’s Space Coast for SpaceX’s 50th landing of a Falcon first stage.
