Chasing Life with Dr. Sanjay Gupta

Four astronauts returned to Earth recently, after a historic 10-day lunar flyby mission in which they ventured farther into space than any human has before. They were part of Artemis II, NASA’s flight to test how well the agency’s Orion spacecraft, and the astronauts, operate in deep space — all in preparation for longer-term trips to the moon and beyond. CNN Chief Medical Correspondent Dr Sanjay Gupta answers some of your health-related questions about the mission, including: How do they sleep in zero gravity? What’s up with all those hot sauces?
