    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

    SCRUBBED!! (Starliner issue)

    This thing is snake-bit

    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.

    Starliner OFT-2 in "fall of 2022" could put the Crewed Flight Test (CFT) in early 2023 and Starliner-1 in late summer of 2023.

    With only 6 Crew Dragon missions currently under contract and Crew-5 in fall 2022 (now with 3 astronauts transferred from a Starliner mission), NASA needs to decide soon on contracting more Crew Dragon missions.

    What a cluster-frack

    Here's the reality: Until the sticky valve root cause is found, there will be no credible date for and OFT-2 launch. It probably will be awhile. They have to disassemble the valves. I've heard dates ranging from early 2022, to May to Fall of 2022 for possible launches of OFT-2.

    Boeing will be ready to send it up the day after it is donated to the Smithsonian's Udvar Hazy Museum of Flight... after which the "Udvar Hazy Museum of Flight" will be renamed the "Udvar Hazy Museum" to denote the change...

    Agreed, this turkey will be lucky to survive CFT-2 if it launches, and that's a big if.

    Atlas V is capped at 28 more launches before retirement, with most remaining birds dedicated to DoD and Amazon (for their Kuiper satellites), and there are no plans to human-rate Vulcan. Even if the 2 Starliners actually fly for NASA commercial missions are out due to there not being a 3rd vehicle as a backup and nothing to launch it with.

    And here comes an update.

    Last we heard it could be as late as mid-2022, which would put the crewed test around December 2022 and the first operational mission in 2023.

    ----------

    MEDIA ADVISORY M21-132

    NASA, Boeing to Provide Update on Boeing’s Orbital Flight Test-2

    NASA and Boeing will hold a joint teleconference at 2:30 p.m. EDT Tuesday, Oct. 19, to update media on the company’s CST-100 Starliner spacecraft. Teams will discuss work on the oxidizer isolation valve issue that was discovered ahead of the planned uncrewed Orbital Flight Test-2 (OFT-2) mission to the International Space Station in August.

    Participants in the briefing will be:

    Steve Stich, manager of NASA’s Commercial Crew Program

    John Vollmer, vice president and program manager, Boeing Commercial Crew Program

    Michelle Parker, chief engineer, Boeing Space and Launch

    Audio of the teleconference will stream live online at:

    https://www.nasa.gov/live

    To participate in the teleconference, media must contact ksc-newsroom@mail.nasa.gov by 1:30 p.m. Oct. 19 for the dial-in information.

    The OFT-2 mission will launch Starliner on a United Launch Alliance Atlas V rocket from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. Starliner will dock to the space station before returning to land in the western United States about a week later as part of an end-to-end test flight to prove the system is ready to fly crew.
