Analog to Focus on Optic Health in Astronauts

Posted on by .

Optic health in astronauts is the focus of NASA’s upcoming campaign at :envihab at the DLR (Germany’s space agency) in Cologne, Germany. Twelve volunteers will spend 30 days in bed with a head-down tilt of negative six-degrees and will live in a five percent carbon dioxide atmosphere. This will mimic microgravity giving researchers a way to study the effects of pressure on astronauts’ eyes and optic nerve in space.

NASA has been concerned with astronaut’s vision since many (but not all) have returned from six-month stays in the International Space Station complaining of vision impairment that seems to be permanent.
