| This pic shows the 'Neutral Bouyancy Laboratory' in Houston, where NASA trains astronauts for spacewalking (EVA's). Underwater we can simulate many of the feelings of spacewalking, but not the view. In this facility they can conduct two simultaneous exercises, and they have full-size mockups of the shuttle, as well as Hubble, the ISS modules, and other major pieces of space hardware. This shot shows the US Lab module in the water, with the S0 truss (which will be installed just before Mark arrives) on top of it. |
