3 month, the other construction crews will all be 6 month each.Thats a lot of unpacking to do. They really drew the short end of the stick for doing all this heavy work
Do we know for how long they will stay up there, is it 3 or 6 months?
I imagine Shenzhou-14 and 15 will be similarly busy, as they each will be dealing with a new big module no doubt also similarly filled with boxes.
