We welcomed Dr. Bruce Damer back to the show to discuss his two new TEDxSantaCruz talks regarding sustainable space exploration and new theories on the origins of life.  Watch the first of his two TEDx talks on sustainable space exploration at www.youtube.com/watch?v=wLMHcUg36yc.  His second TEDx talk addressing new theories on the origins of life can be viewed at www.youtube.com/watch?v=6qiW4aUqtvA.  In the first segment of our 1 hour 28 minute discussion, Dr. Damer introduced us to his concept for sustainable space exploration, including round trips to Mars.  His spacecraft is the S.H.E.P.E.R.D   which he fully explained with great animation in the TEDx talk.  This is a method for capturing and enclosing a small but valuable asteroid between Mars and Jupiter, using a chemical process to mine it for volatiles and to fill special tanks with the volatiles and return the cargo to where it is needed, Mars, the moons of Mars, cislunar space, the Moon, or an orbiting space station.  Bruce spent the first segment of our program discussing this technology and the concept, plus explaining how it can be used to facilitate and enhance human spaceflight including human exploration of the solar system.  The YouTube video is just under 10 minutes so be sure to watch it.  Listeners asked him many questions to fully understand the concept so the YouTube talk and his Space Show discussion go hand in hand with one another.

 

In the second segment, Bruce as asked about the cost to develop, launch, and operate S.H.E.P.E.R.D for a humans to Mars mission.  Bruce did not have costs available but used the Rosetta Mission as an approximate guideline for estimating costs. Also in this segment, he noted the use of inflatables in space and the long history of success in using them back to the early days of the space age and the Echo communication satellites.  He also referenced Genesis 1 and Genesis 2 on orbit through Bigelow Aerospace.  He then said that inflatables would be safer for humans due to less radiation.  Don’t miss his comment on this issue.  Bruce then talked about water and shielding.  As the program was nearing its end, Dr. Damer discussed the second TEDx talk regarding new theories on the origins of life.  He also connected the dots for us with both talks so don’t miss what he had to say. By the way, the sustainable space exploration talk opened the TEDx session and his origins of life talk was the closing talk at the event.  Toward the end, he talked about outreach with his new idea and said he would be giving a FISO talk on S.H.E.P.E.R.D June 24 so those of you who listen to FISO talks be sure to catch this one live or on archives.  Before the show ended, Bill emailed in a question asking him if he had a compelling rational for Martian HSF.  Don’t miss what he said about this.  A Phoenix listener asked Dr. Damer if his concept would help Mars One.  Then a series of questions came in asking Bruce about the use of his idea for going to the Moon, cislunar development, the moons of Mars or someplace else in the solar system.  Bruce said it would support all of these missions and explained why.  Jim asked Bruce to explain why he thought mining an asteroid would be so difficult and far out yet he was mining volatiles from the asteroids he covers up with his plan.  Bruce explained that he was using a chemical process to free up the volatiles, not mining them.

Guest:  Josh Hopkins.  Topics:  Stepping Stones for affordable human exploration missions & lunar far side exploration at Earth-Moon L2.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, https://thespaceshow.wordpress.com. Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

We welcomed Josh Hopkins back to the show to discuss his Stepping Stones approach to affordable human spaceflight from Earth orbit to the Martian moons.  We also discussed exploring the lunar far side from the Earth-Moon L2 point.  In our first segment, Mr. Hopkins introduced us to a potential list of missions in sequence from LEO to the Moon and beyond.  We zeroed in on the lunar farside, both from the L2 Earth-Moon point and from the lunar surface.  Our guest focused our attention on the Aitken Crater Impact Basin and rock sampling for lunar and solar system science regarding different theories about the age and origins of the universe, all of which can tell us much about the Earth, the possibility for life elsewhere, and provide valuable science to further our understanding of the universe.  Mr. Hopkins was both detailed and comprehensive in this discussion, then we switched to robotic as compared to human missions, orbiting missions as compared to lunar surface missions.  Callers inquired about how such missions would be paid for and from which part of the NASA budget.  For example, does the NASA science budget fund the mission, does the cost come from the human spaceflight side if humans are involved, how would they share costs, & is there international cooperation.  One of the important issues brought up in this discussion dealt with the fact that in the science part of NASA, missions are competed for against one another, a process that seems to work well. Inquiring about mission competition with human spaceflight involvement is yet to be determined. Telerobotic missions were discussed and communication latency concerns were brought to our attention.  Josh talked about planned ISS telerobotic demos back on Earth at NASA Ames & with ESA.
      In our second segment, Josh talked about orbital telerobotic cost issues as compared to being on the lunar surface. A listener wanted to know about traversing the Moon from a habitat to the farside & Josh explained the challenges in doing that.  Josh talked in some detail about a radio astronomy observatory at the L2 point & on the lunar surface.  He talked about noise issues at each location & the advantages each brings to the table. Josh was asked about lunar tourism & its potential impact on a radio telescope observatory on the farside. A listener asked about the Google Lunar X Prize for sample return, another inquired about the lunar space elevator, and yet another called in to ask about Stepping Stones as part of the Flexible Path. ISRU lunar development was also a discussion topic.
