This idea of been stuck til next year seems plausible but extreme.
It was even on the BBC World service with interviews from expert insiders. The capsule is a nightmare design and full of questionable design and quality. More a upgraded 60s design with high tech.
In typical Boeing style the fails are much more than stated. As per the 737 max, safety was a cost option, esp given it was a fixed price contract. The tests done in the capsule naturally included the ability to launch, dock , undock and safely land via parachute. All automatically via programs. As you would expect.
Alas, the mods done for the crewed flight somehow involved those auto systems programs ability had been partially removed for expense/ stupidity, it may have been just a new version of programming for the crewed flights but it somehow is not able to fully Auto return. They are now rushing to try and reprogram for the capsule to be able to undock and fly home without crew for safety. So it's considered unsafe for uncrewed return, at this stage.
Apparently they either
-fix it for safe crewed flight return, which is seemingly a tough task in space with no spare parts and still programming problems are a thing.
- get a lift in the next Dragon, which will need to leave two seats spare for the crew return. That means the Boeing capsule must Auto return or at least undock for the gate to be available for the next Dragon flight.
Apparently they will even need new suits for the Boeing crew as they are not compatible with Dragon.
It seems like the typical litany of fuckups Boeing style. At least NASA are on the job or Boeing would just hit the launch button and safety be damned.
I do take many reports with a big dose of scepticism but it seems to have some legs given Boeing's track record on this program.
Meanwhile NASA are very pissed and have to find a use for two unexpected long term guests which use valuable on board resources and a media disaster.
From here on terra firma is seems a good laugh, but I am sure those Astronauts are not happy about getting in the capsule again.
