We welcomed back Robert Walker from the UK to discuss artificial gravity with us given our recent Space Show programs on the subject.  There was an audio issue with this program so listen carefully so you don’t miss anything.  During the first segment of our 90 minute program, Robert went over some of the basics such as the Coriolis effect, the gravity gradient, tethers, centrifuges, the vestibular effect, and more.  He also went over linear acceleration, spin rates, Russian experiments, issues facing space tourists, and spinning a Dragon capsule.  Robert has written many articles on artificial gravity which can be found at www.science20.com/space.  One such article was discussed yesterday. See  www.science20.com/robert_inventor/blog/ingeious_idea_soyuz_crew_tether_spin_way_iss_artificial_gravity_almost_no_extra_fuel-131278.  Also, check out www.science20.com/print/131279; www.science20.com/print/131278 & www.science20.com/print/129424.

In our second segment, Robert talked about both Inspiration Mars and Mars One as it relates to spinning to create artificial gravity, the number of revolutions per minute, simulate programs, and his favorite, a 2-3 year precursor mission at Earth L2.  He wants the mission designed to be a comprehensive test bed for artificial gravity.  Later in the segment while discussing Mars, he suggested we orbit Mars and not land on the planet.  Listen to his reasoning for this type of human Mars mission.  For one thing, he said its much safer to be in orbit.  We then focused on the possibility of microbial life on Mars, we talked about the Viking Labeled Release experiments.  Robert was asked a question about the sleeping centrifuge (you sleep horizontal as one does on Earth).  Partial gravity was discussed as well.  Robert said many times that we must find out what is going on with Mars. He mentioned the Phoenix mission which Mars One is planning to copy to some degree with its robotic mission to Mars in 2018.

Please post your comments/questions on TSS blog.  You can reach Robert via his articles or through me.

Guest:  Jay Barbree.  Topics:  Overview of the space program today, SLS, presidential politics and NASA.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, https://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed NBC veteran space reporter Jay Barbree back to The Space Show for a conversation that focused on our best options for today’s space program.  Our discussion was one hour forty minutes without a break.  We started out discussing Jay’s thoughts when he reported on the last shuttle flight given he had reported on every shuttle flight ever made.  He also told us he had updated and reissued his best selling book “Moonshot” which he co-authored with Alan Shepherd and Deke Slayton.  Remember, if you buy it from Amazon with this specific URL, Amazon makes a contribution to The Space Show: www.amazon.com/Moon-Shot-Alan-Shepard/dp/1453211977/ref=onegiantlea20.  Other topics discussed included a comparison of the original astronauts to astronauts today and the need to return to the Moon.  In fact, Jay told us about ideas being discussed to use the ISS to do a figure 8 loop to and from the Moon rather than crashing it into the ocean at the end of its life.  To do this, he said nuclear propulsion was needed and this led him to discuss the overall need for the nuclear rocket, especially for going to Mars.  A listener asked him if he favored a one way trip to Mars and he said yes.  Don’t miss his complete answer.  Next, we started talking about the Space Launch System which ended up as the main discussion topic for the balance of the program.  Jay strongly supports SLS and is concerned that it might be cancelled.  We talked about what the Obama administration would likely be doing with space and then he talked about his conversations with the Republican candidates and his impressions of each one and their interest in space.  He talked at length about Newt’s Florida primary comments and returning to the Moon in general. He also talked about the need for space settlement given the vulnerability of Earth.  Later, a listener asked Jay if he was familiar with the accusations being made against NASA for how they dealt with the chimps in the early space program and their idea to get KSC to donate space for a chimp museum documenting abuse during their NASA days and dedicating to stopping lab research.  Jay was not familiar with the story but listener Tim found the story on the PETA website:  http://www.peta.org/b/thepetafiles/archive/2012/02/29/peta-to-launch-memorial-at-space-center.aspx.   Jay talked more about the SLS but also about Falcon 9, Dragon, the Boeing CTS 100, and the Atlas 5.  He expressed his concerns many times that the politicians might actually mess up NASA and our future, specifically by cancelling SLS, Orion, or both.  At the end, he told us about his MSNBC.com series “Getting to Mars” which is already underway.  Post your comments/questions on The Space Show blog URL above.
