Confused about Yusaku Maezawa's first "standing on the shoulders of giants" PR photo on the shoulders of Elon Musk in 2018 then launching to the ISS aboard Soyuz, I found that the article lists both a cis-lunar SpaceX mission (planned) and an ISS visit (just launched).
On May 13, 2021, Maezawa announced he would be joining Space Adventures on a trip to the International Space Station in December 2021, via the Soyuz. He aims to spend 12 days on the orbital machine to experience a long duration spaceflight with his assistant, Yozo Hirano, where try to do top 100 things demanded by public as well as recording highlights in preparation to the SpaceX lunar flight.
Twelve days sounds on the short side for an ISS visit.
Of course during the construction phase I would assume that short visits via Soyuz and the Space Shuttle were the norm.
So I'd like to ask:
Question: What was the shortest stay at the ISS once continuous operations and regular crew rotations began? How does Maezawa (planned) 12 days compare?
Since Maezawa is a tourist astronaut rather than a (for lack of a better term) regular crew astronaut, it may be interesting to have a separate number for each.
