We welcomed Bob Zimmerman back to the show to discuss a variety of space news items and events.  During the first segment of our 2 hour 2 minute show, Bob opened up talking about Comet 67P, the Rosetta mission, and the Philae lander which will land on the comet on Nov. 12, 2014.  Bob spent some time describing 67P, the lander, the landing site, and the topography of the landing zone.  Next, I asked Bob about the recent court decisions in Italy regarding the appeals court decision on the seven scientists accused of incorrectly predicting an earthquake that led to lots of damage and death. Bob clarified the issues for us and the decision  of the appeals court.  We talked some about the possible impact on space policy for the recently held mid-term elections.  Bob was asked by a listener if he thought the election result would lead to the cancellation of SLS as well as the NASA ARM project.  See if you are surprised by Bob’s analysis.  Ken in San Diego asked Bob about negative press articles regarding stopping space tourism in light of the SpaceShipTwo accident.  The USA Today editorial of today was cited as an example.  Bob did not think these articles would have any serious or long lasting impact and had much to say about the authors and publications writing them.  Before our break, Rob in Denver emailed in about Comet Siding Spring changing the Martian atmosphere when it swung by Mars.

In the second segment, Jeff emailed in about comments that Virgin has said it would be flying by April.  Bob was very skeptical about that timeline.  He had much to say about the investment and more regarding Virgin.  Bob then spoke about the upcoming Orion test flight set for Dec. 4 and heat shield issues.  Our guest spent some time dwelling on the heat shield issues which he said helped make his case that SLS/Orion were not sustainable projects.  Ben called from Orange County to talk with Bob about the Bigelow module going to the ISS in 2016, then they talked a bit about solar sales.  Ed emailed Bob to see if he knew what alternative launcher Orbital might choose given the Antares problems.  Bob spoke about the upcoming Russian rocket test for the new Angara 5 rocket.  SLS John called in about earlier comments Bob made regarding the Saturn 5, then they talked about SLS.

We welcomed Michael Belfiore back to the show to discuss a variety of space news and current events items, plus trends in the industry.  During the first segment of our 1 hour 41 minute program, Michael talked about DARPA given his recent book on the agency, then we turned to the recent commercial crew down select NASA announcement naming the Boeing CST100 and SpaceX Dragon as the two companies that NASA will continue supporting for commercial crew.  We spent lots of time talking about Boeing and SpaceX plus everyone was wondering if Sierra Nevada and Dream Chaser would find a way to stay in the game.  The next topic was the Google Lunar X Prize challenge. Michael pointed out that a government had gotten to the Moon fist with a rover, the Chinese, thus the rules of the contest were changed to allow the contest to continue.  Marshall called to talk about the down select process and winners. SLS John called to tell us that he thought Dream Chaser and SpaceX would be the winners.  He and others suggested Boeing was the conservative choice.  He also asked about the news that a Boeing-Bezos deal was in the making for the new American made RD180 engine replacement.  Michael suggested throughout our discussion that the old guard or the traditional aerospace industry and participants were under lots of pressure from NewSpace.

In the second segment, we took a call from Doug who commented on the down select process.  Michael then talked about the Tesla deal for Nevada and their proposed gigafactory for electric car batteries.  We talked about electric cars in general, then Tim called to suggest a conversion kit for conventional autos to turn them into electric cars.  I questioned that from a market perspective.  Michael then introduced space manifesting and we talked about the 3D printer on the way to the ISS.  Michael mentioned Maven which was to be inserted into Mars orbit Sunday evening, 9:37 EDT.  News update:  Maven’s orbital insertion was a big success!  Congrats to NASA and the entire Maven team.  We also talked about Comet Siding Spring,  Suborbital flights came up and we heard Michael express concerns about Virgin Galactic & confidence with the Lynx and XCOR.  He talked about the early spaceflight participants and the risks they would be taking.  Visit his website, http://www.michaelbelfiore.com.

Guest:  Dr. David Brain.  Topics: Mars MAVEN Mission, Mars science.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, https://thespaceshow.wordpress.com.  Comments and questions should be relevant to the specific Space Show program.

We welcomed Dr. David Brain of the NASA MAVEN Mission team to the program for a discussion about MAVEN and Mars science.  In the first segment of our 1 hour 22 minute program, Dr. Brain provided us with an overview of the MAVEN Mission which was launched on Nov. 18.  As we heard, it is on track for its orbital insertion around Mars on Sept. 22, 2014.  I asked Dr. Brain if he thought Mars orbits were getting crowded and also if he knew if there were traffic management issues in orbiting Mars.  We also talked about the Indian Mars mission, Mangalyaan, as it was launched a few days before MAVEN and will arrive shortly after MAVEN arrives at Mars.  Dr. Brain, in describing MAVEN, said it was going to answer two questions:  1) What happened to the atmosphere of Mars and 2) What happened to the water and where did it go?  We then talked about the absence of a Martian magnetic field but we learned that there are strongly magnetized rocks along the edges and such rocks are 10-20 times the magnetic strength of similar rocks on Earth.  Dr. Brain provided us with theories on this.  We extrapolated that it was possible for something similar to happen on Earth.  He also talked about magnetic fields, how one might generate a magnetic field on Mars & more.  This latter point was in reply to a listener question asking if terraforming included creating a Martian magnetic field.  Our next topic dealt with how these types of missions are developed, the hardware and scientific tool risk issues, the use of heritage hardware and instruments, program funding, and review panels.  Marshall called and talked about instrument redundancy, electronic improvements from mission to mission and more.  We also talked about sending data back to Earth using the Deep Space Network (DSN).  This brought up questions about private Mars missions using the DSN for their communications.

In the second segment, Doug called to ask how MAVEN was impacted by the government shutdown. Dave relayed the shutdown stories to us which were most interesting, especially since it went right up to the minute for possible mission delays of 18-24 months.  In fact, MAVEN did get an exemption from the shutdown but not because of its science.  It was exempted because of its function as a communications relay satellite.  Also in this segment, Dave responded to listener questions asking how the instruments are designed, tested, and protected for their trip to Mars so they would be sure to work.  Dave took us through the entire process for planning, designing, developing and testing hardware & operating components  over and over again.    This is a fascinating inside look at what is involved in a successful Mars, lunar, or planetary mission.  Doug then asked about methane on Mars and here Dave had much to say about competing methane theories and the latest findings from instruments on Mars including Curiosity.
