We welcomed back Dr. John Jurist to present his popular talk, “The Space Program of the 1960s.”  I have uploaded to The Space Show blog his Power Point presentation that he uses with this talk  so be sure to visit it.  He refers to many of the Power Point slides during this two hour Space Show program, especially slides featuring historical pictures.  The specific URL for this program on our blog is https://thespaceshow.wordpress.com/2015/10/24/dr-john-jurist-sunday-10-25-15.  During the first segment of our two hour program, Dr. Jurist discussed the origins of our space program going back to the 1920s with Robert Goddard and his rockets, and even earlier to Tsiolkovsky with the rocket equation.  John then advanced the story through WW2, V2 rockets, the development of the hydrogen bomb, the creation of the NSF, then on to Sputnik and the eventual launch the first American satellite.  During this overview, Dr. Jurist received many listener questions as well as questions from me so this is quite the comprehensive discussion.  John also pointed out the interest in space from the public which drove media coverage.  He referenced Walt Disney, von Braun’s popular work, sci fi films, & Colliers Magazine articles.  He mentioned several stand out events such as JFK’s Rice University speech, the Apollo 1 fire and then Apollo 7 which contained thousands of human spaceflight safety advancements and improvements and the testing of many of those advancements with the Apollo 7 flight.  A listener asked about nuclear propulsion and NERVA.  This resulted in a phone call from Dr. Dewar who continued the discussion with nuclear propulsion but advanced it to include the development cryogenic systems to support the H bomb and then these systems making their way to NASA.  John and Jim had much to say about the H bomb and space development connections so don’t miss this discussion.  By the way, Dr. Dewar is returning to The Space Show on Dec. 6.  John talked about the biomedical advancements in aviation that contributed to safer HSF. Here, he mentioned the work by Dr. John Paul Stapp and others, especially out of Holloman AFB in New Mexico.  Don’t miss this discussion or the relevant PPT slides.

In the second segment, John from Ft. Worth called to continue the discussion about the H-bomb and space connections, huge airplanes to deliver the large bombs and the later development of compact warheads which lead to the use of smaller missiles.  They also compared these advancements to the Soviet Union program of the day as the soviets used a different system for the bomb which resulted in it being smaller than the initial American weapons.  The two John’s continued talking about cryogenic development.  Dr. Jurist then advanced the discussion to the economic benefits of space development and how space has advanced the standard of living for everyone on the planet.  Some side discussion topics including space and former V.P. Spiro Agnew, space shuttles, Skylab, and bone metabolism resulting in the DEXA scan.  Dr. Doug called in to talk about baby boomers and the creation of graduate students in STEM and non-STEM fields.  He also asked if a DEXA scan could be made small enough to go to the ISS for real time measurements.  Dr. Jurist offered an easier way for those real time studies.  Several listeners asked Dr. Jurist if we could recreate this type of program today.  John said he was doubtful, especially given the IRB would likely have a total fit with self-experimentation.  He spent more time on the Apollo 1 fire, then he got questions about the opportunity cost of space development asking if we would not have had the same advancements if not more had we spent the money on programs other than space.  Don’t miss how John responded to this question.  Another listener pointed out emergency and trauma medical advancements as a result of recent wars and asked our guest if those advancements would have come about had it not been for the recent wars that helped develop these new treatment protocols.  Again, don’t miss how Dr. Jurist responded to this question.  As our program was ending, Dr. Jurist offered concluding comments that you will certainly want to hear and consider.
