This morning, the CST-100 Starliner spacecraft, atop an Atlas V rocket, returned to the Vertical Integration Facility (VIF) as work continues for Starliner’s second uncrewed orbital flight test.
Teams from Boeing and United Launch Alliance (ULA) have begun assembly of necessary support structures around the spacecraft to access the vehicle’s Service Module.
Boeing engineers are progressing a systematic inspection and troubleshooting plan to determine the cause of the unexpected valve position indications in the Service Module’s propulsion system, which led to the scrub of Tuesday’s launch.
One of the first steps will be to power on the spacecraft, a process that takes several hours. This step will enable the team to send commands to the Starliner and receive data real-time.
“We’re letting the data drive our decision-making and we will not fly until our integrated teams are comfortable and confident,” said John Vollmer, vice president and program manager, Boeing’s Commercial Crew Program.
Updates will be provided by NASA and Boeing as information is available.
