Christopher Ferguson, commander of the final space shuttle flight and now a Boeing executive, has stepped down as commander of the first piloted test flight of the company’s troubled CST-100 Starliner commercial spacecraft, he and Boeing announced Wednesday. He has been replaced by NASA astronaut Barry “Butch” Wilmore.
Engineers are troubleshooting a small air leak aboard the International Space Station that was discovered last September, NASA reported Thursday. While it poses no safety threat, the lab’s three-man crew plans to seal themselves in the Russian segment of the station this weekend to help engineers pin down the leak’s location.
Crew Dragon astronauts Douglas Hurley and Robert Behnken thanked their space station crewmates for a productive two-month visit, readied their SpaceX capsule for departure and stood by for a final “go” from flight controllers to undock Saturday night, setting up a Gulf of Mexico splashdown Sunday afternoon.
Space station commander Chris Cassidy and Robert Behnken floated back outside Tuesday for their fourth spacewalk in less than a month, completing preparations for future upgrades including the eventual installation of an airlock that will allow commercial experiments to be moved into and out of vacuum as required.
NASA has completed an exhaustive review of software problems and procedural oversights that prevented an unpiloted Boeing Starliner capsule from docking with the space station last year. The agency is implementing 80 recommendations to clear the way for a second test flight later this year and, if all goes well, Boeing’s first piloted flight next spring, officials said Tuesday.
Space station commander Chris Cassidy and Robert Behnken plan to float outside Friday for the first of up to four spacewalks needed to complete the replacement of aging batteries in the lab’s solar power system. NASA managers hope to get the work done in time for Behnken and crewmate Douglas Hurley to return to Earth aboard their Crew Dragon capsule by around Aug. 2, officials said Wednesday.
