    Default Atlas V: Boeing Starliner Orbital Flight Test-2 (OFT-2)

    Boeing's re-do of the December 20, 2019 OFT-1 un-crewed mission, which was nearly lost twice due to dozens of system malfunctions, design issues, and corporate hubris.

    Key were the Starliner Mission Elapsed Timer starting at Atlas V launcher power-up at T-11 hours instead of liftoff, and the attitude control thruster map (tells the avionics computer which thruster points where) being incorrect. They used the default map instead of adjusting it for the new vehicle configuration. Downhill from there...

    =====================

    Mission: un-crewed flight test to the International Space Station; launch, approach, dock, stay a few days, undock and return to Earth.

    Date: July 30, 2021
    Time: 1453.Eastern (1853 GMT)
    Launcher: ULA Atlas V
    Pad: LC-41, Kennedy Space Center
    Landing: White Sands Space Harbor (WSSH), White Sands Missile Range, New Mexico.

    Webcast: NASA TV, NASA YouTube channel

    We're standing down from today's #Starliner Orbital Flight Test-2 launch.

    During pre-launch preparations, our engineers detected unexpected valve position indications in the propulsion system.

    Oh, good Lord....

    Michael Sheetz @thesheetztweetz (CNBC)
    Nield: However, "there were some rather significant differences in how several safety issues were assessed between NASA and Boeing" before launch. "We got very close to launch without having identified the valve problem" with OFT-2.
