As the resolver for a Manifold prediction market, I've been following this story closely for the last couple months. [0]
Back in December, HN user JanSolo wondered if the three astronauts assigned to the leaking Soyuz MS-22 might be evacuated via the Dragon Capsule. [1] Since the default evacuation plan was to send the next Soyuz MS-23 up early and unmanned, Dragon seemed unlikely...unless, of course, the coolant leak was due to a design or manufacturing defect affecting other Roscocosmos craft.
This latest Progress MS-21 news makes the defect hypothesis much more likely, in my view. A joint NASA-Roscocosmos investigation found that the original MS-22 coolant leak was caused by a micrometeroid about 1mm in diameter. I don't expect them to walk that back, so perhaps the defect makes these coolant lines more susceptible to puncture than before?
