John Batchelor and I did a quick 2015 year in review. We both agreed that the latest Falcon 9 launch by SpaceX was a potential game changer with the success of their flyback booster landing upright at the Cape. We also talked about the rest of this particular SpaceX mission which was just as impressive. For planetary science, we selected several mission for our 2015 best including New Horizons, Dawn, Akatsuki which started orbiting Venus after being lost for five years, and the Japanese Hayabusa 1 and 2 missions,. We commented that we were disappointed in the suborbital industry progress other than for Blue Origin and their recent successful test flight with their rocket return to the pad. John liked the European Rosetta Mission for Comet 67P and specifically the Philae lander. We summarized our short discussion by wishing everyone a very Merry Christmas and Happy New Year, plus we look forward to 2016 being another exciting year for space.

We welcomed Don Nelson back to the show for this 90 minute discussion regarding his Commercial Space Shuttle Freighter (CSS Freighter) concept.  During the first segment, Don provided us with an overview of our current launch and human spaceflight situation, he talked about safety and reliability, then he started describing his CSS Freighter Concept.  You can learn more about it at his website, www.spacetran21.org.  He spent time explaining why wings were needed despite the common misconception that they become worthless mass in space.  He said over and over again that if one does the trades, wings come out far better than carrying additional propellant for a vertical landing.  He also said he was a strong proponent of full reusability, not just first stage reusability.  In response to several questions, he said his CSS Freighter was modeled after the shuttle but with new upgrade designs and technology though to save money and reduce development time, the freighters were to be based on existing technology.  He had much to say about the difficulty they had in upgrading space shuttle systems so this time around he said upgrades would be modular and as close to plug and play as possible.  His idea is that the freighters will be built and operated by the private sector.  He suggested the extensive use of composite materials to save on mass and to use reusable Space Shuttle Main Engines (SMEs).  He referenced the Air Force X-37B program, he talked about the advance state of the thermal protection systems (TPS) for this top secret spacecraft suggesting it would be the TPS of choice for the freighters.  Our guest was challenged in both segments regarding other reusability options including the advancement toward success represented by SpaceX and the Falcon 9.  Don said it was first stage only, he was talking about full vehicle reusability and making the case for his approach with wings.  Don’t miss the challenges and the replies. Don also spelled out the advantages of horizontal as compared to vertical vehicle landing regarding reusability.

In the second segment, BJohn asked about the Soviet version of the shuttle, the Buran.  Don mostly talked about lessons learned by their not having a reusable space shuttle main engine (SME).  Don was asked about international vehicle participation in his freighter project. He said not with this Congress and referenced our policy on not talking with China.  Don was also asked for the rational for doing this and he focused on competition.  Make sure you hear this discussion.  He said he was including the Air Force in his plan given the rapid turnaround time for the vehicle (five days).  He explained the Air Force market in detail and is in touch with key Air Force people.  In addition, he has made presentations to members of Congress and their staffs plus key people at NASA.  I asked him how they responded to the concept.  You don’t want to miss what he said about that.  Alex asked an email question about launch pads and NASA having altered or gotten rid of the shuttle launch pads.  Don said launch pads were not an issue, even suggested foreign launch sites, but did say KSC was a prime launch location in the U.S.  Don attacked expendable rockets over and over again in both segments so Ben from Seattle pressed him as to why his reusable freighter would be more reliable than an expendable rocket.  He said each flight of an expendable rocket was a test flight.  Our guest received a questions about suborbital flight evolving to orbital flight, listeners asked about private Bigelow space stations, and one listener wanted his thoughts on the Skylon.  Tim called in and talked about chemical rockets and rocket fuel. He also inquired about scramjets and Big Dumb Boosters.  Doug called in to challenge his reusability comments citing the Falcon 9 to make his case that wings were wasted mass.  Don’t miss this discussion.  When asked if he thought things would change as a result of the coming elections, he suggested that a new congress would likely terminate SLS given our budget & SLS problems.  Don’t miss the balance of his concluding comments.

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, 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.  The Space Show/OGLF is now engaged in its annual fundraising drive. Please see & act upon our appeal at https://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.  Please post your comments/questions on The Space Show blog URL above.
