Flight Engineer Sunita Williams conducted another session of an
experiment that measures cosmic radiation and its effects on astronauts’
central nervous systems. A specific focus of the experiment is abnormal
visual perceptions, known as phosphenes or light flashes, while the eyes
are closed and the impact of particles on brain functions in micro-gravity.
The three station residents completed their fourth session with an
experiment of hand-eye coordination. This experiment tests the idea that
the decrease in motor skills reported by some astronauts is due to the
brain adapting to being in space. Scientists hope to test the theory
that while the brain is adapting to space, it is unable to fully provide
the resources necessary to perform normal manual skills.
On Feb. 27, the International Space Station Independent Safety Task
Force issued its final report. It was released simultaneously to
Congress, NASA and the public.
