Guest:  Robert (Bob) Zimmerman.  Topics: This was a wide ranging discussion starting with climate change & ending with budget, CR, & commercial crew issues.  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 Bob Zimmerman back to the show for this one hour 55 minute discussion starting with the announcement regarding climate change and the upcoming IPCC report which has been leaked to the press.  The primary topic for this first segment was climate change, the leaked IPCC report and an analysis of it.  Bob fielded listener comments and questions including Marshall’s who had hands on experience with the very first computer climate model in the early 70’s.  Bob summarized all his comments saying that science needed to be skeptical and he was optimistic that skepticism was coming back to the field of climate science.  We then switched to space and NASA for the balance of this program.  As a transition, Bob talked about solar activity and the solar max.  In response to a listener question, he commented that if Mars or anyplace in space were developed using the Antarctica model, it would doom commercial space activity.  He stated over and over again that the model needed was the profit model for space and planetary development.

In the second segment, we talked about new commercial contracts for Arianne 5 recently announced, and how important these were to Arianne who needs to show a profit for the first time.  I asked Bob about NASA’s Redirect Asteroid Mission given all the attention it got last week at AIAA Space 2013.  Bob had much to say about this mission, most of it not supportive or positive, and then I mentioned the NASA press conference which is archived as part of the Space 2013 taped interviews and the fact that it is to be SLS dependent. This started Bob and others on SLS rants, mostly not supportive of it, and also Orion.  Bob was emphatic that Orion with SLS would not be a deep space mission & at one point he cited comments by Russian that their next generation Soyuz would have bathroom facilities on board and Bob said with Orion, it was strictly diapers for the crew.  We talked about Inspiration Mars and Mars One.  Bob was skeptical about both happening. Listen to the reasons he cited for his perspective.  Bob also talked about Bigelow Aerospace and its potential, listeners asked about Planetary Resources and the Redirect Mission, then we talked about the need to lower the launch costs to LEO.  Bob brought us current with SpaceShip2 & the latest powered demo flight, then John called in to argue about SLS with Bob.  This was an interesting give and take.  As Bob has done on other programs, he continued saying he does not want a space program which is a government program which in his eyes is doomed to failure.  He wants the private sector to prevail.  As the show was ending, I asked Bob for this thoughts on the budget, CR, and future commercial crew funding .

Guests: John Batchelor, Dr, Pal Brekke, Dr. David Livingston:  Topics: The Northern Lights, solar cycles, Solar Max & Earth’s climate.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, https://thespaceshow.wordpress.com.

During our 11 minute plus discussion with Dr. Pal Brekke & John Batchelor, we discussed the current solar cycle 24, the Solar Max, sunspots, climate change, and the Northern Lights (Aurora Borealis).  Please note that John Batchelor spoke with Dr. Brekke in Norway via a cell phone so the audio is up to its usual quality.  Dr. Brekke explained the Northern Lights, answered many questions and then we connect our discussion to the current solar cycle, the issue of fewer sunspots at this time and why, plus what does it mean to see fewer sunspots.  Near the end of the segment, I asked Dr. Brekke about the impact of the double peak which is making the Solar Max quite different.

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, 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.  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.  Please post your comments/questions on The Space Show blog URL above.
