Nasa Doctors Tackle The Medical Challenges Of Extended Space Travel

摘要

Space travel takes a toll on the human body. Not only are astronauts exposed to cosmic radiation, they also contend with bone loss and muscle atrophy after long periods in reduced gravity. As NASA engineers grapple with the transportation and logistical challenges of missions to the Moon and Mars, space agency doctors are tackling the physiological challenges.rnUnlike terrestrial medicine, which relies on enormous hospitals using heavy equipment, astronauts conducting exploration missions will need lightweight devices for prevention, diagnosis, treatment and rehabilitation.
