Q&A with Keith Gendreau, principal investigator of the first X-ray space communications experiment (members only)

Boeing’s Starliner crew capsule could take off in October on its first unpiloted test flight to the International Space Station, a company official said recently, while SpaceX finishes up the investigation into the explosion of its Crew Dragon spacecraft during a ground test earlier this year.

NASA astronauts Doug Hurley and Bob Behnken returned to Earth Sunday with an on-target splashdown in the Gulf of Mexico at 2:48 p.m. EDT (1848 GMT) Sunday. The astronauts completed a two-month stay on the International Space Station on a test flight of SpaceX’s Crew Dragon spacecraft.

A SpaceX Falcon 9 rocket blasted off Monday from NASA’s Kennedy Space Center, then the launcher’s first stage returned to landing at nearby Cape Canaveral Air Force Station after sending a Dragon supply ship toward a rendezvous with the International Space Station.
