The New Yorker MEDICINE ON MARS How sick can you get during three years in deep space? BY JEROME GROOPMAN

چکیده
The rocket science will be the easy part. With a projected launch date of 2020, NASA is planning to send astronauts on a three-year mission to Mars—including six months in transit each way—and its technicians are reasonably confident about the mechanical aspects of the trip. The truly vexing problems are turning out to be the medical ones. Can human beings survive long-term exposure to deep-space radiation and zero gravity? Can astronauts who have medical emergencies be treated en route? What about the psychological effects of the stress and confinement? These are questions that various officials at NASA—along with a number of consulting experts—are trying to answer.
