Mike Suffredini is leaving NASA after 10 years at the helm of the International Space Station program overseeing assembly of the largest spacecraft ever built. He chatted with Spaceflight Now in his final weeks as space station program manager, sharing his memories and vision for the commercialization of low Earth orbit.

A commercial Dragon cargo capsule wrapped up a four-week stay at the International Space Station on Monday with a departure from the complex at 12:01 p.m. EDT (1601 GMT). The spacecraft splashed down in the Pacific Ocean at 5:48 p.m. EDT (2148 GMT) with several tons of research specimens and equipment.

Sunday’s flight of the United Launch Alliance Atlas 5 rocket from Vandenberg Air Force Base in California was scrubbed due to a wildfire burning south of the pad. The launch delay allows crews to remain in place to battle the blaze. The lack of Range availability this week means the next launch try won’t come until Sept. 26.
