Risk of Adverse Health Outcomes and Performance Decrements resulting from Non-Ionizing Radiation during Spaceflight
Sunlight exposure primarily affects the eye and skin and is mitigated by current standards and countermeasures. An increase in the prevalence of high-power ground-based lasers capable of reaching the ISS, and possibly even the Moon, could cause acute laser exposure damaging hemorrhagic retinal lesions resulting in temporary or permanent damage to vision.
Astronaut Joseph R. Tanner, STS-115 mission specialist, looks toward the digital still camera of his space walk colleague, astronaut Heidemarie M. Stefanyshyn-Piper as the two share extravehicular activity (EVA) duties during the first of three scheduled spacewalks. Stefanyshyn-Piper’s full body is reflected as a tiny figure in Tanner’s helmet visor. The STS-115 astronauts and the Expedition 13 crew members are joining efforts this week to resume construction of the International Space Station.
