As I understand it, the missions are crew specific. Someone I talked to said they were essentially organizing and doing inventory.
That is incorrect. They bumped two astronauts off of the Crew 9 mission roster so that Sunni and Butch would simply be absorbed into that crew.
I think the typical Crew is 3 or 4 astronauts and typical staffing level of the station is 7.
They are not "stranded" and never were. Even when the Starliner vehicle was in question it was still Sunni and Butch's primary ride home in the event of an emergency or evacuation. Even though the vehicle had questions about it, it was considered safer for those two to ride home in that vehicle than to ride, essentially as cargo, in Dragon. Remember everyone has a space suit that is specific to them AND specific to the vehicle they are set to fly in. That way, if it is necessary they can plug into life support systems on board that craft during reentry. A typical hatch closing and leak test procedure can take an hour or more. I watched the hatch closeout on the Crew Demo1 flight several years ago. It was long and boring as heck. A single piece of dust or something prevented a perfect seal and they had to re-open the hatch, wipe it with a clean lint free cloth, then re-close and monitor as the pressures Dragon pressure was reduced and held steady. IF they station were damaged in a manner that required immediate evacuation (damaged such that life support could not be sustained) they would have to immediately move to their respective vehicles, close the hatches, and get away. There could be a pretty good chance they they do not have a perfect seal and being plugged directly into their ships systems would be the most advantageous move.
The "victims" of this whole ordeal are the two SpaceX NASA crew that were bumped of of the Crew9 mission and are not getting their turn in space.
