Guest: Dr. Jeffrey Hoffman. Topics: space walks, space tourism, solid rocket boosters, space policy, space vision. Dr. Jeffrey Hoffman was our guest for this Space Show program. In our initial segment, we discussed the Hubble Space Telescope and its repair missions, training for the repair missions, and what its like to do work in space outside the spacecraft. We asked Dr. Hoffman about any sense of speed or height when doing a space walk and if space tourists could do an EVA.
