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: Dr. David Kipping. Topics: Searching for Exomoons and Exoplanets with Kepler Space Telescope (KST). 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. David Kipping to the program to discuss the search for Exomoons and Exoplanets. The primary tool for these searches is the Kepler Space Telescope (KST). We talked about the methods used to search for the exomoons, mainly planet transits. Later in our discussion we talked about the other methods including detecting wobbles and using pulsars. Another discussion issue was the fixed field of view for the KST (about 10 degrees) and the benefit of having multiple KSTs to look at different and broader fields of view of the sky. Dr. Kipping was asked several questions about finding exomoons in the habitable zone (Goldilocks zone). We also discussed the randomness of targets and the small number that are actually in the field of view from Earth. Charles in an email brought up spectroscopy in the searches.
In the second segment, we started out discussing pulsars and their role in these searches. Dr. Kipping went into some detail to explain to us the radiation pulses and how they can be interpreted in the exoplanet/moon searches. As you will hear, pulsars are not likely to be located in the Goldilocks zone but Dr. Kipping did give us an idea of the best targets for a visit were we to have interstellar space travel. Later we talked about the JWST and infrared searches along with the potential the JWST brings to astronomy. This discussion took into account the NASA budget, competition with the science missions and human spaceflight, and making hard choices for this or that funding. Our guest took some listener questions about nanosatellites and swarms of mini-KSTs. Dr. Kipping had much to say about this idea, including that it was a good one. Another issue covered was the international effort in these searches. I asked our guest about amateurs and planet searches. He told us about an interactive website, www.planethunters.org plus other programs that involved non-professionals in the searches. Near the end of the program, Dr. Kipping discussed the differences with the KST public data and private data.

Nicholas (Nick) Johnson. Topics: Space debris issues. 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. We welcomed Nick Johnson back to the show for a comprehensive discussion on space debris issues. We started out with an assessment of the space debris problem as of today. Here, Mr. Johnson talked with us about the impact of sun on space debris through both the solar max and the solar minimum. I referenced the NRC report and asked if concurred that we were at the “tipping” point in the debris issue. We talked about cleaning up debris and our guest said that various options were being looked at but we were not there yet. Nick mentioned a few possible technologies but that funding was needed, demo projects needed to be carried out, and that international cooperation and funding consortium ideas were being explored. Space attorney Robert called in regarding some of the legal issue needing to be addressed based on the Outer Space Treaty, the Liability Treaty and other legal documents. Perhaps the biggest legal issue is that of needing permission from the owner of the hardware to retrieve or do something with it so that it does not add to the debris problem. We did talk about mitigation strategies for newer satellites and I inquired why the 25 year boundary for keeping the satellite from becoming debris. Jerry called in and wanted to know about the possibility of magnetic cleansing and suggested VASMIR. Another listener asked about satellite upset events that happen when a satellite gets hit with really small flakes of debris causing the satellite to reboot. Before the break, we talked about the return to Earth of the Upper Atmosphere Research Satellite (UARS) and Nick talked about tracking the return of objects. Don’t miss this discussion. I also asked him about Burnt Frost, the U.S. satellite shoot down in 2008. We started the second segment with a listener question about possible titanium tanks on Phobos-Grunt and reentry concerns. Nick said that Russia said the main tanks were aluminum and that Russia should be addressing reentry concerns. We talked in general about the problem of hydrazine and it remaining frozen during reentry. Another listener asked about plutonium on board spacecraft and the Russian accident in Canada with Cosmos 954. Another listener asked about cubesat and possible debris issues. Space tugs for debris removal were discussed as were Earth-based lasers. International cooperation was discussed and of course ITAR came up. As the program was ending, we talked about NASA’s reentry plans for both the ISS and the Hubble Space Telescope. Nick also clarified the law for us regarding keeping pieces of satellites or debris that hit the Earth as they remain the property of the launching country.
