back to article Second Soyuz springs a leak, astronauts stuck on ISS for an extra month

Russia's space agency will hold off returning three astronauts from the International Space Station as it works with NASA to investigate a coolant leak issue that impacted an uncrewed freighter spacecraft last weekend. The Progress MS-21 – also known as the Progress 82 spacecraft – arrived at the floating space lab in October …

    one possibility that has been floated is that a micrometeoroid pierced an exterior radiator.

      A second theory

      It's been reported else where (sorry, I don't recall where) that it would be very unlikely for micrometeoroid damage to have affected two radiators in such a short time frame*, so the possibility of a manufacturing defect is also being considered.

      * although everyone knows that the fact that the probability is vanishingly small makes it a certainty!

      Surely all they have to do is crack a space hen egg into the radiator?

    Is a Progress a Soyuz?

    If not, how much commonality is there in those systems?

      Soyuz is the crew-rated version; Progress is the cargo version.

      There's a lot of commonality if you exclude the life-support systems.

    If I were a manager at SpaceX, I think I'd have a crew getting a Dragon capsule prepped, just in case.
