"Swelled heads, atrophied legs, radiation threats — space takes a toll on the human body, and some health problems still elude doctors more than 50 years after the first spaceflight.
At the Johnson Space Center here, the home base for NASA’s human spaceflight program, scientists probably have until the 2030s to dissect these problems before the agency sends astronauts to Mars — a mission that would take about three years, or nearly six times the current standard tour of duty on the space station.”
“Astronaut Clay Anderson took this picture during the shuttle orbiter Endeavor mission. Interestingly, NASA explains the curve of the Earth as seen in his helmet as not coming from the curvature of the earth itself, which appears only slightly curved from the height of the space stations, but instead is due to the curve of the helmet visor itself. / Clayton C.
