Then they leave the rest of the ISS owners with a big repair bill. Given the limited lufetime, the recent rental price hikes by NASA would make a lot of sense. Think real estate hardball. Time to read the fine print.

In addition to the fact that man-lifts that can reach the top of an SH/SS stack are insane, if not impossible, there is the fact that using a person in a man-lift to reconnect the crane to the tip of an unstable landed SS (like SN-10) is foolhardy. I was relieved when SN-10 blew up, and I’ll bet some folks at SpaceX were too!

Not as a personal attack on you, but more because IF (and that’s a heavy IF) the ISS has such a catastrophic failure it’ll be a huge black eye for manned spaceflight as a whole.

Hopefully greater minds than ours are on the case! I’m sure I’m not alone in having quality tools, both forged and cast which supplied excellent service for multiple decades until they failed catastrophically and splintered into bits…. The point you bring up is worrying indeed!

I’m no expert but an increasing leak rate may be the result of a propagating stress fracture. Given the criticality of the module, what if any analysis has been done or is in work to quantify the risk of a catastrophic failure.
