Trailblazing Medicine

To prepare for the day when astronauts leave low-Earth orbit for long-duration exploration missions, space medicine experts must develop a thorough understanding of the effects of microgravity on the human body, as well as ways of mitigating them.

Looking forward to the day when astronauts depart on extended exploration missions, this assessment of the future of space medicine analyzes what is necessary to keep a crew alive in space as well as the medical challenges faced by interplanetary astronauts.

Second Suns is the unforgettable true story of two very different doctors with a common mission: to rid the world of preventable blindness. Dr. Geoffrey Tabin was the high-achieving “bad boy” of his class at Harvard Medical School. Dr. Sanduk Ruit grew up in a remote village in the Himalayas, where cataract blindness—easily curable in modern hospitals—amounts to an epidemic. Together, they pioneered a new surgical method, by which they have restored sight to over 100,000 people—all for about $20 per operation.
