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 back Dr. Chris Impey to the program for this 63 minute program discussing his latest book “Beyond: Our Future In Space” and related policy, economic, and technical space questions.  Visit his website, www.chrisimpey.com for more information.  Please remember if you buy his book through TSS/OGLF Amazon portal, Amazon will donate a percentage of the sales price to The Space Show.  Instructions are on the website and all archived show summaries.  We began our discussion with Dr. Impey providing us with the background to his latest book in that many people believe that our space program is in the doldrums, that NASA is beset with many problems and for some, they wonder why even bother with space.  Dr. Impey wanted to show the audience that this was not the case so he wrote his latest book to show the benefits of space development and why we must have a future in space.  The book mostly focuses on the human spaceflight potential but we discussed science missions and a space program that would be much broader than just human spaceflight.  He also said the new industry was ready to go viral but had not done so yet.  He suggested some dramatic events might be the turning point in changing the momentum so don’t miss what he had to say about this.  We talked about NASA and NewSpace and he said it was no longer either or and that NASA was now partnering with NewSpace companies and the private sector.  Dr. Impey highlighted the growth in the cubesat industry as an example of things changing.  We talked about international space missions and he mentioned both Russia and China.  With regards to China, ITAR was discussed as was the potential militarization of space.  A listener asked our guest about an economic model and he said that was still troubling.  He thought mining asteroids would not be viable if at all for a very long time.  Listen to his explanation behind this conclusion.  On the other hand, he thought space tourism was shaping up to have a robust market and was optimistic that the companies would soon be flying.  I asked him for his five year timeline for big events.  He listed operations with SpaceShip2 and Virgin and that SpaceX will commercialize reusability.  He also expected to see fleets of commercially operating nano and microsats.  Next,, he said the Moon or Mars was harder with people and that would take place over the next 10-15 years.  He suggested China would visit the Moon with taikonauts in about a 15 year time frame.  He said the Moon would happen when we have a new generation of talent and innovative people pushing it at the ground floor level.  Listener Larry asked him about the regulatory risk.  He thought it would be relatively stable as it is now.  BJohn asked him about planetary science, astrobiology, geology, and biology along with the Big Bang Theory.  Next, we discussed astronomy, including Earth astronomy but also exoplanets and the habitable zone.  A listener asked him about finding life on Mars, either past or present and how that might impact the public with supporting space.  Chris had very interesting comments about this so don’t miss them.  Another listener asked him for his preference in destinations, the Moon or Mars.  He said the Moon.  Listen for the why.  Space settlement was discussed, more on the NASA budget and a question came up about the use of nuclear propulsion.  Near the end of the show he was asked about efforts in pursuing Faster Than Light Travel (FTL) and warp drive.  He was not optimistic in this area.  As the program was ending, I asked our guest how university teaching had changed over the course of his career.  This led us to talking about student loans and university funding from the state and federal government.

This program is archived on The Space Show website, podcasting, and blog sites with permission from John Batchelor. Please visit the John Batchelor Show website for more information about this fine program, www.johnbatchelorshow.com. The topics in this 11 minute segment focused on the origins of our Moon and finding microbial life on Mars.  We talked about the lunar impact theory and why it is still preferable to competing theories for the origins of our Moon.  After exploring the lunar origin theories, we focused on finding microbial life on Mars and talked about Earth analogs including asteroid craters, the Antarctic dry valleys, methane plus a few others.  Toward the end of the segment, John asked Chris about our technology for finding life, comparing what robots of today and the near future can do versus what humans can do at this time.  Chris provided a most interesting response, including a brief analysis of the cost benefits of each type of mission.  If you have questions or comments, please post them on The Space Show blog.  If you would like to send an email to either Mr. Batchelor or Dr. Impey, do so through me at drspace@thespaceshow.com and I will forward it for you.

Dr. Chris Impey, Sunday, 4-15-12

http://archived.thespaceshow.com/shows/1752-BWB-2012-04-15.mp3

Guest:  Dr. Chris Impey.  Topics:  We discuss Dr. Impey’s new book, “How It Began: A time-Traveler’s Guide To The Universe” along with astronomy, physics, and cosmology topics. We also discussed space policy and the future of human spaceflight plus science missions. 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 Dr. Chris Impey back to the program to discuss his new book.  Remember, if you buy the book from Amazon using the following URL, Amazon makes a contribution to The Space Show/OGLF:  www.amazon.com/How-It-Began-Time-Travelers-Universe/dp/0393080021/ref=onegiantlea20.  For the Kindle version, use www.amazon.com/How-It-Began-Time-Travelers-ebook/dp/B005LW5J30/ref=onegiantlea20.  During the first half of the program, Dr. Impey talked about the book’s structure which is a bit different from other books addressing similar topics.  For example, the further outward in the universe you go via reading the book, the more backward in time you go which is why the book is a time-traveler’s guidebook to the universe.  Dr. Impey explains this to us and the going back in time is with us for the entire Space Show discussion.  Our first stop was our Moon and our guest had much to say about it, including its origins, why and how it orbits Earth at about 240,000 miles, and more.  We also learned what Earth would probably be like without the Moon.  As we went into deeper space after leaving the Moon, we talked about the Kepler Space Telescope (KST) and finding exoplanets plus searching for exomoons.  A listener asked about the delay encountered with supernova 1987A and our guest explained this to us.  I also asked our guest about his statement on page 19 at the bottom about time and Apollo becoming a “distant cultural memory.”  This turned into a lively discussion you don’t want to miss.  We then talked about human spaceflight (HSF) with Dr. Impey suggesting that due to the high cost of HSF and the constant improvements with robotics, we might very well see advanced robotic missions over the coming years rather than human missions which may prove unaffordable.  Don’t miss this conversation, it may very well be an accurate forecast for the future for HSF and robotic missions.

In the second half of our program, we moved out into the universe and talked about the Big Bang, First Light, and the James Webb Space Telescope (JWST).  We also talked about large Earth-based telescopes, Hubble, and looking back close to 13 billion years with JWST while the universe is about 13.7 billions years old.  We talked about why one cannot see the origins of the Big Bang with optical telescopes, but what we can “see” with microwaves.  A listener asked about the Cosmological Principle and another asked about human time travel.  This brought up the topic of black holes.  Questions came up about string theory and the Multiverse, and then John called in to discuss both dark energy and dark matter which turned out to be another fascinating discussion led by Dr. Impey.  Later, we went back to discussing HSF and we learned about the potential for nanobot probes for interstellar missions.  Fleets of such probes acting in a sort of relay fashion might just be real someday.  Near the end of the program, Dr. Impey discussed geopolitics as a driver for space exploration and said more about the early time after the Big Bang for the first 100 million years or so.
