Okay stranded might be the wrong phrase but not being able to get home for 9 months doesn’t seem like the right outcome for a 10 day itinerary to me. I’m glad everything is working out the end though.
"not being able" is just another way of saying "stranded" again.
Please read up on the details of this adventure and you'll come to realize that whoever is putting this phrasing into the media is trying to lie to you!
It's a "holy shit, two cakes" situation. I don't think anyone who's devoted enough to being an astronaut to go through all it takes is going to mind more time in space doing space stuff.
Or maybe the astronauts, who themselves stated they weren't stranded, are big fat liars. Personally, I'll take them at their word.
