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.

We welcomed Dr. Zubrin back to the show for this 90 minute discussion about everything Mars and the Mars Society.  Dr. Zubrin opened up by telling us about the Mars Artic 365 program (http://ma365.marssociety.org) and their fund raising efforts through Indiegogo and other programs (www.indiegogo.com/projects/ma365-a-one-year-mars-simulation-in-the-canadian-arctic).  Throughout the entire program, Dr. Zubrin received questions/comments about Arctic 365.  He was asked about telepresence and having the sim in a more populated place than the arctic.  Bob dismissed telepresence as not being nearly as effective as having humans work “on Mars” & he stressed the importance of simulating a real Mars working mission.  Bob went over the logistics and scheduling for this first crew for Arctic 365, plus remaining opportunities and ways for people to participate in the program as the crew selection process is closed.  We talked about the costs and crew skill sets, plus Mars Society fund raising efforts for this program.  Jack emailed about radiation on Mars and as before, Bob suggested it was not as big a risk as many claim.  He was also asked about teaming up with Mars One on Arctic 365 program.  Bob said he was open to doing things with Mars One and suggested Arctic 365 would be a perfect training program those who train the Mars One crews.  Later, Bob was asked about doing a completely private mission to Mars.  Bob used this as a spring board to describing the kind of policy & political leadership in government and NASA, both of which he said absent for now.  He even proposed some broad based financing suggestions.  Doug called wanting to know his thoughts on Phobos & Deimos.  Bob used this as an opportunity to support a flyby mission. He was not that supportive of visiting the Marian moons.  Don’t miss his explanation for his position.  As the segment was ending, I asked him about life on Mars.  Bob thinks there probably is life on Mars, don’t miss what he had to say about this.

In the second segment, Steve asked Bob about the Delta V needed for going to the Moon as compared to Mars.  He talked about the Moon being easier than Mars.  Again, don’t miss all of Bob’s response to Steve’s question/comment.  NASA and political leadership were more fully discussed in this segment, then he was asked about the SLS. Here, Bob had a lot to say. While critical of SLS, he would not cancel it.  Again, don’t miss his comments on this topic.  He talked about SpaceX & Falcon 9, heavy lift in general, crew size on a Mars mission, and finally possible threats from the Chinese space program.  Toward the end he talked about electric propulsion for slow cargo missions, then I asked him for his thoughts on the Mars cycler system.
