During our 11 minute plus discussion with Dr. Ed Stone & John Batchelor, we discussed the current status of the Voyager 1 and 2 spacecraft and their soon entry into interstellar space. Dr. Stone, who has been the Chief Scientist of the Voyager project since the beginning with the project development in 1972, then the launches in 1977, talked to us about the Voyager mission, the Golden Record onboard Voyager 1, the role of Dr. Sagan, and what it will mean when the spacecraft finally leaves the heliosphere and enters interstellar space.  We also talked about the rest of Voyager’s life after the power goes out for good around 2020.  When Voyager was launched in 1977, it was able to do a flyby of the giant gas planets in a special orbit that comes about once every 176 years.  This orbit also made it possible for Voyager to reach Neptune in just 12 years!  Also discussed were total Voyager 1 and 2 mission & development costs plus their annual operating costs which run around $5 million.

Guests:  Kimberly Arcand, Megan Watzke.  Topics:  Touring our Solar System with our two guests.   Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, http://thespaceshow.wordpress.com.  Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information.  We welcomed Kimberly (Kim) Arcand and Megan Watzke to the program to discuss their new book, “Your Ticket To the Universe: A Guide To Exploring The Cosmos” published by Smithsonian Books.  Visit their website for more information our guests and this amazing book, www.yourtickettotheuniverse.com/Index/Home.html.  Also check out this YouTube video for the book, www.youtube.com/watch?v=3-KamC0Plro.  If you order the book using this Amazon URL, Amazon will make a contribution to The Space Show:  www.amazon.com/Your-Ticket-Universe-Exploring-Cosmos/dp/1588343758/ref=onegiantlea20.

During the first part of our 90 minute discussion, our guests explained why they wrote this book and how they came up with its unique structure, format & famous person quote at the beginning of each chapter.  We talked about the pictures used in the book and a few of the items that stood out to me including “Taking an Alien to a Baseball Game” which helps us understand visible light along with all of the other types of light.  A listener with a copy of the book emailed in to ask about the use of the terms light second, light minutes, and light hours when describing objects in our Solar System.  Their discussion of Pluto as a dwarf planet came up in addition to my talking about the book as an excellent teaching tool for school libraries, students of all ages, even adults.  Our authors talked about art and I noticed the inclusion of the famous painting Starry Night in the book.  Don’t miss what Kim and Megan had to say about why Starry Night was used in their book and the overall subject of art, space science, aesthetics, and the night sky abundant with stars.  As our segment was ending, we talked about Mars analogs here on Earth such as Svalbard and Rio Tinto among the many Earth Mars analogs referenced in this book, plus the book’s astrobiology focus.

In our second segment, I asked our guests if space exploration was worth it and why.  Don’t miss what each had to say in answering the question.  We talked about the NASA budget, what is accomplished with the budget, and general population misunderstandings about the actual amount of the NASA budget.  I mentioned a TV documentary on the Dutch East Indies Company and the necessity of human exploration.  I asked our guests what they thought our world would look like had we sent robots out instead of humans in those very early and risky exploration missions.  A listener asked about the description of the book as both a coffee table book and a science book, and we talked about that hybrid description.  Near the end of our discussion, I asked each guest for their favorite place mentioned in the book where they would want to hang out.  You might be surprised by their choices.  Both Kim and Megan signed off with excellent closing comments that you will want to hear and remember.

If you have comments/questions, please post them on The Space Show blog.  You can contact both guests through their website, Twitter, and Facebook, as well as through me.

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, 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.
