They continue to be as important as they were on Monday. None will be flight-ready before this incident is fully evaluated, corrections in process/design applied and the system is cleared to fly again. All safety mechanisms worked as designed and the crew landed safely. The astronauts on the ISS still have their Soyuz if they really need to come down.

Nothing changed. Soyuz is still incredibly reliable. It's a bit old, a bit expensive (Crew Dragon, flying on reused Falcon 9's, will be much cheaper) and very cramped for 3 astronauts, but it does the job and has been doing it for what, 40 years?
