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, http://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.

Guest: Open Lines with Dr. David Livingston. Topics: Bone loss issues, Droid podcast suggestions, bisphosphonates in space, reusability, flyback boosters. You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://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. The Space Show/OGLF is now engaged in its annual fundraising drive. Please see & act upon our appeal at http://thespaceshow.wordpress.com/2011/11/21/space-show-2011-fundraising-campaign. During the announcement part of the program at the beginning, I talked about another Droid podcast possible solution from a listener using the DoggCatcher app. I also mentioned recent general press articles about success being claimed with the use of bisphosphonates to stop bone loss in space: www.dispatch.com/content/stories/national_world/2011/12/06/osteoporosis-drugs-helped-astronauts-scientists-say.html. As mentioned on the air, I’m on the nationally syndicated radio show, The John Batchelor Show, tonight, Wednesday, Dec. 7, 6:30-6:45 PM PST discussing this as co-host with John. The expert guest is Dr. John Jurist, a lifetime member of the aerospace medical association and one of the early researchers on this issue back when NASA was starting such research. You can hear us live at www.wabcradio.com/article.asp?id=531472. If you miss the live stream, the segment will be archived the next day at John’s website, http://johnbatchelorshow.com. For your information, I typically do the Wednesday evening segment at either 6:30 PM or at 6:45 PM PST. I am often on air alone with John but sometimes I bring in an expert to discuss a specific topic such as tonight with Dr. Jurist. I also went over my December schedule for programming as my travel plans to Los Angeles are now known as are Space Show plans for the balance of the year. Our first caller was Jeff from the UK who wanted to talk mostly about the new Earth-like planet that Kepler has found, the Kepler-22b. We also talked about faster than light travel, the recent neutrino experiment, photons, and more. Charles was the next caller and we talked more about the new planet found by the Kepler Space Telescope. Charles mentioned the two planet finding methods, the transit and the wobble methods. He also mentioned Armadillo Aerospace and their recent success with the STIGA A launch vehicle. You can read about it and see the video at www.rlvnews.com. Scroll down to this headline: STIG A – another video + recovery info. In the next segment, Tim called in with questions about the Air Force contract for the flyback booster which went to Lockheed and will use Spaceport America. This prompted quite a discussion on reusability, flyback boosters and their payload penalties, ocean recovery for the first stage, and expendable, renewable, and disposable rockets. Our caller also inquired about nuclear power and the plan to do a ballot initiative in California to shut down the California nuclear power plants though they generate 16% of California’s electrical power. John from Atlanta called in to talk about ocean recovery, the faster than light experiment and his thoughts that tachyons provide a reasonable explanation for the faster than light experiment. During the program, we also discussed on orbit repair for both LEO and GEO satellites and what the future might hold for such efforts.
