Moving a 6,000-pound spacecraft is tricky, like when we maneuvered @EuropaClipper into JPL's thermal vacuum chamber, where teams simulated the conditions it will experience in space. Up next: Moving the spacecraft from our California clean room to @NASAKennedy in Florida. pic.twitter.com/t6UqtTuHHE

NASA, @BoeingSpace, and @ULALaunch are targeting no earlier than Friday, May 10, for launch of the agency’s Boeing Crew Flight Test to the @Space_Station, pending resolution of the technical issue that prevented the May 6 launch attempt: go.nasa.gov/3wrilzq pic.twitter.com/HNoNic3d7Q

The astronauts have begun ingress into #Starliner — taking their seats in the spacecraft. They'll undergo a series of checks, including umbilical hook ups, communications checks and suit checks. They'll also do spacecraft checks so they are ready for flight. pic.twitter.com/GsE2lEzJXa
