Dr. Frank Rubio was the first astronaut to live in space for more than a year continuously. This was only achieved by a radiator malfunction in the spacecraft. Apparently, a meteoroid or “space junk” hit the spacecraft and caused a leak in the radiator (seems like spacecrafts have the same issues as cars). When Rubio finally returned home, he was temporarily unable to walk due to the microgravity effect to his body. This 6 month mission turned into a year long endeavor finally comes to an end. It’s unclear if Rubio will be returning to space anytime soon however, I’m sure he’s glad to be home.
