We welcomed back Dr. Chris Impey for a one hour one segment discussion about his two recent books, “Dreams of Other Worlds: The Amazing Story of Unmanned Space Exploration,” and his newer book “Beyond: Our Future in Space.” We started our discussion with Dr. Impey describing “Dreams of Other Worlds” which describes 11 unmanned space missions that have made a difference in our understanding of distant worlds. We focused on a few of the 11 missions including Viking, Cassini, Voyager, & the WMAP mission. I asked Dr. Impey what would have been included had the book been written later. The Dawn Mission would have made it, so would the Kepler Space Telescope, New Horizons, Curiosity, and probably others. We then switched to the use of ground based telescopes and here Dr. Impey talked about how many of the telescopes are being repurposed for a new life doing different types of observation astronomy. Dr. Impey was asked about his favorite missions. He mentioned Viking and the WMAP microwave telescope mission and this led to his talking about The Big Bang, dark matter, and dark energy. I asked Chris about the recent article in The Economist about the two Chicago area scientists proposing a new theory on dark matter. Chris had read the article and had some interesting commentary on it and the proposed theory. Robert sent in an email asking our guest why there have been no life detection experiments on the NASA and other planetary missions. This sparked a good conversation on the subject which you do not want to miss. Chris proposed a very plausible reason why no suck experiments have been carried out but let us know what you think by posting on the blog. Another topic discussed was planetary protection. Linda from Austin asked our guest about the UofA astronomy and cosmology programs and students, then Bill asked our guest if he had read “The Martian” or seen the movie. Chris had both read the book and seen the movie which we discussed for several minutes. Don’t miss this discussion as Dr. Impey made some interesting points about both the book and the movie and the plausibility of the story line including the initial dust storm which caused the problems for The Martian. Before the end of the program, Chris fielded some questions about future missions. We addressed the Europa Clipper mission but he said many may be disappointed for what was not being included on the mission so again listen to what he had to say. He suggested a Titan mission would be interesting. In his book “Beyond” Our Future In Space,” Dr. Impey addressed the new commercial missions & human spaceflight. Chris guided us through all sorts of possibilities for future human spaceflight. Nuclear propulsion came up with Dr. Impey having much to say about how beneficial it would be if we had it though it was still futuristic. We spoke of advanced technology & the Decadal Survey and its impact on the type of science projects that get undertaken due to funding. Will sent in a note asking about the recent article about Elon Musk wanting to get to Mars in 10-15 years given the various risks Earth faced, including extremism. Dr. Impey also said it was probably unrealistic to think that one could have a $500k ticket price for Mars, another part of the Elon Musk article. Dr. Impey offered us good summary comments so don’t miss them. The last question dealt with a possible science backlash and referenced the following Huffington Post article: www.huffingtonpost.com/entry/solar-farm-suck-up-the-sun_566e9aeee4b0e292150e5d66.

We welcomed Dr. Erik Seedhouse back to the show for a variety of timely discussion topics. During the first segment of our 1 hour 37 minute program, Erik started out making comparisons with past polar exploration and going to Mars. He also said that going to Mars anytime in the foreseeable future would be a survival trip. We talked about Erik’s books on Virgin Galactic, Polar Exploration and Mars which will soon be released, and additional books on Dragon, Mars One, Mars via the Moon, and XCOR, all to be released over the coming months. Erik then spoke about his ISDC talk re comparing polar exploration to going to Mars and commented on the speaker following him, Dr. Logan (he was not sure of the first name but we think it was our friend, Dr. Jim Logan). He talked about radiation shielding and water per what Dr. Logan had to say including the need for 10 meters of water shielding to equal the protection here on Earth. Erik had much to say about radiation and shielding which prompted multiple emails from Dr. Doug in S. California seeking clarification and adding to Erik’s comments. I read all of Doug’s radiation themed emails throughout the first and second segment of today’s program. Don’t miss Erik’s conclusions regarding the radiation risks and shielding needs for a Mars mission, how astronauts would live and work on Mars as well as the Moon. Erik next talked about Virgin Galactic and XCOR saying he thought XCOR would be the first to fly commercially. When asked about the biggest passenger risk on a suborbital flight, Erik said it would be the cardio-vascular risks. Erik got questions regarding SpaceX, Elon Musk, and the Mars Colonial Transporter. He again stressed the way to go to Mars was via the Moon and that would be his preferred space policy. He also put forth his Mars simulation study plan. Don’t miss it, I think it’s a good one.

In the second segment, John from Florida called to comment on delays and how long commercial suborbital flight was taking since the success of Spaceship 1. John seemed to compare the lack of progress with suborbital flight to how much progress was made with aviation and in particular jet travel. I took the first pass at responding to him, then Erik offered his comments. What do you think? Let us know on the blog. Erik was then asked about other human factor issues than radiation. Dr. Seedhouse went through a laundry list of health risks and concerns for astronauts in deep space and on long duration spaceflight. He was then asked about the regulatory regime for suborbital space, then he wanted to define space given Virgin Galactic may not flight beyond 50km which is not space. Don’t miss what he had to say about this and the overall health risks for astronauts in deep space. Near the end of the show, Erik addressed space settlement. He said it would be a natural expansion and would happen automatically with returning to the Moon and going to Mars via the Moon. In his concluding comments, he suggested that advocates and space enthusiasts need to adjust expectations and understand the technology involved because its harder and more costly to do things in space, including suborbital space, than originally thought and expected.

We welcomed Alan Boyle back to the show for this 1 hour 42 minute discussion on numerous space news items & topics.  During our first segment, Alan talked about the “two year rule” which suggests space tourism & suborbital commercial flights are just two years away.  Throughout the program Alan kept suggesting that 2014 might be the end of the two year rule!   Alan gave us an overview of the spaceflight companies building vehicles.  Our next topic was the Yamato Meteorite, a Mars meteorite that may indicate past life on Mars.  He compared this to the 1996 meteorite announcement and said that some of the Yamato team members were the same as those addressing the 1996 “discovery” (www.nbcnews.com/#/science/space/tiny-blobs-tunnels-meteorite-revive-debate-over-life-mars-n38431).  In talking about Mars, I brought up the Viking experiments by Dr. Gil Levin , then a listener emailed in a question about the UK Tom Bower book on Branson, “Behind the Mask.”  Georgia followed with a question about the forthcoming NASA commercial crew down select, then I asked Alan for his view of SLS.  Alan said it definitely had a role to play.  Allison called from her car to inquire about private space stations & microgravity issues.

In the second segment, we discussed Planet Labs & their recent launch of cubesats from the ISS.  Alan also explained how the cubesats were launched from the station, plus since he had seen some of their images, we got a report on image quality.  Todd emailed in a additional question about cislunar transportation/lunar settlements.  Alan had several questions pertaining to what would actually be done in a lunar settlement.  Elon Musk & his Mars plans came up and we spent a few minutes talking about that subject.  Alan said the biggest dud story of 2013 in his opinion was Comet Ison.  John called from Ft. Worth & I queried him again on SLS but he actually wanted to discuss Mars & present day capabilities.  He then talked about the need for advanced propulsion for Mars flights.  He said he would back off his SLS support had there been plans for a second generation shuttle, depots or something that would be a real program.  He said SLS was a real program & any program was better than no program.  Alan then said he was looking forward to 2015 with New Horizons, Dawn, & SpaceShip2.  He also mentioned the ESA Rosetta mission,  then as the show was ending, he was asked about the Chinese lunar rover.  The final question from Sara was about the value & importance of human spaceflight.
