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.

We welcomed Dr. Bruce Damer back to the show to discuss his new concept for enclosing an asteroid with a Xenon gas filled enclosure, the Shepherd concept, to help make human spaceflight sustainable. During the first segment of our 83 minute program, Dr. Damer introduced us to the concept, compared it to the NASA ARM baggie option as well as the boulder option, plus the private sector potential for the mission even without NASA. You can read the paper we talked about during the show which was recently published in New Space, “Shepherd: A Concept for Gentle Asteroid Retrieval with a Gas-Filled Enclosure” at http://online.liebertpub.com/doi/full/10.1089/space.2014.0024. During this segment, Dr. Damer talked about capturing fuel in space and talked about a demo project, possibly in LEO. Doug emailed in several questions and comments about the NASA ARM video, then asking if Dr. Damer’s idea could be used to extract the most valuable volatile thus only having to bring back a portion of the asteroid. Don’t miss what Bruce had to say in response to Doug’s comments and questions. Claire in Boston emailed in to voice her unhappiness with ARM and the fact that many others like her did not like the mission. She asked Bruce what the value was even with his idea rather than using the resources for returning to the Moon or going to Mars. Bruce suggested the mission would produce excellent science and enhance commercial spaceflight. Again, don’t miss his full answer to Claire’s question. One of the later topics in this segment dealt with forces on the asteroid in the baggie concept that could possibly destroy the asteroid. He explained why Shepherd would probably be different.

In the second segment, Dr. Damer talked about the Shepherd mining variant, the Shepherd biological variant, and the Shepherd fuel variant. I asked him if this was similar to 3D printing in space and he said it was, then he explained his answer. He also said the founders of the Shepherd idea were putting it out to everyone as Open Source as he said would be valuable to give it away to industry. Later he said the most likely to develop this technology would be NewSpace entrepreneurs. Jim in Denver emailed in about the applicability of Shepherd to human spaceflight to Mars. Here, Bruce talked about orbiting Shepherd models supplying the surface group below. He also said being on the surface may not be the best way to set up a settlement but listen to the total scope of his comments on this subject. He even cited Von Braun, Bonestell, Willy Ley and others for depicting this idea using a Mars transfer orbit. Tim called in with several questions about short period asteroid. When asked for concluding comments, Bruce said he was very excited about Shepherd as it represented 35 years of simulation and other work and now he was meeting with the right people with the right skills to make a project like this happen.

We welcomed Dr. Bruce Damer back to the show to discuss his 3D real time simulations, the human NEO mission study & design project, planetary protection, astronaut safety and much more.  Here are the websites Bruce mentioned on air:  www.damer.com, www.levityzone.com, and www.digitalspace.com.  In addition, later in our discussion Bruce also talked about a Dave Brody YouTube video that was relevant to our discussion.  You can find this video at www.youtube.com/watch?v=UAm9escDxu0.   In the first segment of our 1 hour 31 minute discussion, Dr. Damer talked about the renewed interest in asteroid projects within NASA and by others, especially after the Russian event a few months ago.  Dr. Damer had lots to say about a recent meeting he attended at AMES, budgets, and the renewed interest in the subject.  Listeners started asking him questions early on, including questions about docking with an asteroid with little or no gravity, the use of aerogel to collect micrometeorite particles, plus the recently announced commercial asteroid missions being planned.  Robots versus humans came up many times, Curt asked about the use of the ISS, prioritizing budgets, lunar basis, etc.  Doug called in regarding the incremental approach Dr. Damer had mentioned or as referred to in our discussion, stepping stones.

In the second segment, we talked about the designs on www.digitalspace.com and the Brody YouTube video per the above URL.  Also discussed was planetary protection with the use of the gravity tractor. We talked about needed lead times to interfere with a potentially dangerous NEO that might be headed for Earth,  then more questions came in about a lunar base and what Bruce thought to be more important, the lunar base, Mars, or the NEO mission.  Doug called in to discuss and challenge some of the mission planning ideas Bruce put forth, especially around trial and error, R&D, incremental development and long time lines.  Near the end, we talked about human spaceflight safety & the ideas put forth by Rand Simberg & others that we needed to take more risks, not make safety the extreme priority.  Bruce had many relevant & important comments on this subject.  Final comments focused on 50-100 years in th future with asteroid & other capabilities but only if we keep moving forward today.
