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.

We welcomed Brian Altmeyer to the program to discuss his Oct. 6, 2014 Space Review article, “The Strange Contagion of a Dream: How Space Visionaries Hijack Governments to Change the World (see http://www.thespacereview.com/article/2611/1). During the first segment of our 1 hour 27 minute discussion, Mr. Altmeyer introduced us to the background behind writing this article, how he got the idea for it, plus he explained the overall impact space visionaries have had on him and his interest in space development.  Our guest took us back in time to the V2 program, Von Braun, and the politics of beating the Soviet Union to the Moon.  He made the case that both the Soviet Union’s and the US space program fed off each other in the form of competition to not only develop military space resources and ICBMs, plus our civil space programs as well.  I then asked our guest if he thought competition with China over their lunar and long range plans would result in a similar push for civil and commercial space.  His response was very interesting.  Ellen in Portland sent an email suggesting we did not have inspirational or effective leaders today like we had with Von Braun and others.  Brian disputed that and made reference to Elon Musk at SpaceX several times during our discussion.  Gerald Driggers called to talk about the impact of the International Geophysical Year on our early program.  Gerald worked in the early space program & had much to say about the main space personalities of the time along with the early rockets.  Our guest was asked about vision and Mars One, again he brought up SpaceX, and then he talked about exoplanets.  I asked him about the second to last paragraph in his paper regarding leadership issues and many waiting or expecting a new leader to come on the scene in a future election.  Don’t miss his comments on this issue.

In the second segment, Brian was asked about space budgets serving as a limiting factor & if SpaceX was carrying too much of the burden for our moving forward with space development.  Listeners asked him about sustainable space projects inspired & pushed by advocacy.  Do the projects continue or eventually die off?  Allison sent in a note asking our guest why we even needed HSF.  For his response, he cited reasons often provided by Elon Musk when he gets this question or one like it.  Near the end of the program, Ron emailed our guest to challenge his visionary outlook by asking if he had considered the reality of applying  human medical factors, engineering realities, orbital mechanics, & the known science for rockets & human spaceflight regarding the type of visionary statements made by Brian during the show.  This proved to be an interesting discussion as Brian said there were two ways to resolve such issues.  One way would be through testing and incremental progress to resolve or mitigate problems and the other way would be to just do the flight and sort of learn on the job, realizing there would be lots of casualties but at least we would be flying and learning.  I asked our guest if he was dismissing the known engineering &science including medical science.  He said he was not but clearly he preferred the second approach to problem solving. What do you think?
