Not really either. The astronauts were stuck on the ISS, which is designed for long-term occupation. As long as they can get (unmanned) supply missions, they can remain there indefinitely. The Space Shuttle was not designed to remain in space for an extended time, nor to be resupplied in orbit, meaning that being unable to safely return to Earth is a very difficult situation to deal with.
