Summary

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.

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?
