He's set to return home on Sept. 27 after spending 371 days on the International Space Station. Rubio’s long mission is helping NASA prepare for even longer missions. Throughout his stay aboard the orbital lab, he’s tested new diets loaded with nutrients, new space-based workout regimens, new space gardening techniques, and more. His work is critical to keeping future spacefarers safe and healthy. Congratulations Dr. Rubio!
