Re: Starlink launched
The plan had been for the Dragon astronauts to stay on ISS for only a week before returning. Now NASA is considering having them stay for months, so they can get some actual work done while they are up there and to avoid the US contingent being reduced to a single person. If the extended stay happens, the astronauts will need to be trained on the activities they will be doing. That will delay the Dragon 2 launch by several months.
