The astronauts who came home from the International Space Station last month experienced some drama on the high frontier, and some of it accompanied them back to Earth. In orbit, the astronauts aborted two spacewalks, both under unusual circumstances. Then, on October 25, one of the astronauts was hospitalized due to what NASA called an unspecified "medical issue" after splashdown aboard a SpaceX Crew Dragon capsule that concluded the 235-day mission.
