SCRUBBED: Russia's new Nauka module misbehaved during docking.

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...
