JSC2012-E-211703 (31 Aug. 2012) --- In a training facility at NASA's Johnson Space Center, Timothy Lindsey (left) and astronaut Andrew Feustel put their heads together as they evaluate in Earth's gravity environment some procedures for a possible zero-gravity space walk in the near future. The "real" procedures would be put into play by the Expedition 32 crew members aboard the International Space Station. Personnel from JSC’s Mission Operations Directorate along with a handful of astronauts and engineers spent a good part of the afternoon on Aug. 31 evaluating the procedures. The need for a follow-up session of extravehicular activity eventuated when the two space walkers from Expedition 32 were unable to complete all their objectives on an Aug. 30 space walk.
