radiation

uests: Dr. Ted Bateman, Dr. Jeff Willey. Topics: Microgravity environment of space and bone loss in astronauts due to radiation. Our guests for today, Dr. Ted Bateman and Dr. Jeff Willey, both of Clemson University, are involved in bone loss studies at the radiation levels astronauts will probably encounter on long duration spaceflights, space settlement, and possibly even on a flight to Mars. Their research flows from a project funded by the National Space Biomedical Research Institute (NSBRI) in Houston.

Guest: Dr. Robert Zubrin. Topics: Goals and vision for space program, Augustine Commission. Dr. Robert Zubrin returned for this Space Show program to provide us with his assessment of the Augustine Commission's report and to put in context his goals and vision for our space program. In our first segment, Dr. Zubrin said that the Augustine Commission failed by not presenting a plan of action . Our entire segment was devoted to this discussion as was much of our program. Heavy lift was brought up and he said we would go nowhere in space without it.

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.

Guests: Dr. Henry Helvajian, Dr. Siegfried Janson. Topics: Small satellites, satellite history, present and future satellite technology, launch rate. We welcomed Dr. Henry Helvajian and Dr. Siegfried Janson, editors of "Small Satellites: Past, Present, and Future," to the program. This book is available from the One Giant Leap Foundation (OGLF) website at www.amazon.com/dp/1884989225?tag=onegialeafou-20. Remember, buying books through the OGLF Amazon partners page helps in supporting The Space Show.

Guest: Ralph Nansen. Topics: SSP, economics, low cost space access, RLV, policy and political leadership. Ralph Nansen was our guest today to discuss space solar power (SSP) and his new book by Apogee, "Energy Crisis: Solution From Space." This book is available on the One Giant Leap Foundation website at www.onegiantleapfoundaton.org/books. Please purchase your copy using this link so that Amazon contributes to The Space Show. In the first segment, Mr.

Guests: Brent Sherwood; Dr. A Scott Howe. Topics: Space architecture, space development, life support systems, human spaceflight missions. Brent Sherwood and Dr. A. Scott Howe were with us to discuss their new AIAA published book, "Out Of This World: The New Field Of Space Architecture." During the first segment, space architecture was defined. This is important so make sure you hear it as it is applicable to our discussion of the subject. We talked about some of the issues that differentiate space architecture from its terrestrial counterpart.

Guest: Dr. James Dewar. Topic: nuclear rocket, breaking the taboo, private space development and industrialization. Dr. James Dewar was our guest to discuss his new Apogee published book, "The Nuclear Rocket: Making Our Plane Green, Peaceful and Prosperous." This book and his earlier book, "To The End Of The Solar System: The Story of the Nuclear Rocket," will soon be on the One Giant Leap Foundation book page as an Amazon partner. Buying these books from the One Giant Leap Amazon link allows Amazon to financially support The Space Show.

Guest: Dave Ketchledge. Topics: "Rocket Science," nuclear power, space policy, space education. Dave Ketchledge was our guest to discuss his new book on CD, "Rocket Science." You can order this book and find out more about it by visiting his website, www.rocketengineer.bravehost.com/. During Segment 1, Dave talked about the need for space engineering and rocket education, how his book fills this need, and what it means for future engineers in all disciplines, not just those related to space.

Guest: Dr. Petra Illig. Topics: aerospace medicine, passenger health and safety, FAA, spaceflight participants, and pre-existing medical conditions. Dr. Petra Illig was our guest today to discuss with us aviation and personal spaceflight medicine from the perspective of the spaceflight participant. Our discussion started out by asking Dr. Illig to extrapolate from her body of work on aviation passenger health to the health factors concerning the spaceflight participant.

Guest: Alfred Zaehringer. Topics: rocket science, rocket equation, Mars, chemical rockets, space tourism, low cost space access. Al Zaehringer returned to The Space Show to discuss his two books. Al was the editor of "Rocketscience: The Journal of the Detroit Rocket Society, Inc. 1947-1952," which is available from http://www.apogeebooks.com. This is a must have reference book, one of the very best of its kind.
