Guest: Dr. Robert Fitts. Topic: "Prolonged Space Flight and Human Muscles." We welcomed Dr. Robert Fitts to the program to discuss his new research on astronaut muscle atrophy as a result of space flight. The full title of the study for which he was the P.I. is "Prolonged Space Flight-Induced Alternations in the Structure and Function of Human Skeletal Muscle Fibres." The study was published in the Journal of Physiology, Vol. 588, pp. 3567-3592 in the September 2010 edition.

Guest: Mary Roach. Topics: Mars, space medicine, microgravity, human spaceflight issues. We welcomed Mary Roach, author of "Packing For Mars: The Curious Science of Life in the Void." You can purchase this book from Amazon by using the One Giant Leap Foundation (OGLF) book page and Amazon then contributes to OGLF/The Space Show.

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.
