Q&A with Opher Doron, general manager of IAI’s space division (members only)

Keeping with its mantra of fly, fix and fly again, SpaceX says it has resolved a valve problem that kept one of its Falcon 9 boosters from successfully touching down on a barge in the Atlantic Ocean in April, ahead of another landing attempt after a launch from Cape Canaveral set for Sunday.

A SpaceX-owned Dragon cargo craft departed the International Space Station at 1011 GMT (6:11 a.m. EDT) Friday, and made a parachute-assisted splashdown in the Pacific Ocean at 1547 GMT (11:47 a.m. EDT) with more than 3,000 pounds of cargo, research specimens and other hardware.

A Chinese Long March 2D rocket launched Venezuela’s second Earth-observing surveillance satellite Monday, adding a new space-based reconnaissance asset the country’s government says it will use to aid security forces, emergency responders, farmers, and health professionals.
