This will help me bring better programming to the audience. We welcomed back Bob Zimmerman to discuss current and hot topics happening in space at this time. During the first segment of our 2 hour 6 minute discussion, Bob asked me about the recent Bay Area-NAPA earthquake on Sunday morning, August 24, then we switched over to space topics starting with SpaceX and the Falcon 9R test launch explosion. Next, Bob talked about the failure of the ESA Galileo GPS launch involving the Soyuz-Arianne. Several questions came up regarding the ESA GPS system. We also talked about other regional GPS systems. Bob moved us to the launch failure (booster rocket) for the Air Force Hypersonic vehicle, then to the decision by Sea Launch to take a break. Bob had much to say about the Sea Launch partnership now involving mostly Russia and the Ukraine. Russia and the ISS came up and here Bob also had much to say, including going over the news that Russia may now be interested in extending the life of the ISS. Bob suggested some important Russian reasons for wanting to do this, see what you think. The Atlas RD-180 rocket engine came up for discussion as did the upcoming NASA down select for commercial crew with Dream Chaser, SpaceX, and Boeing with their CST 100. Next up was SLS which I permitted to be discussed for a while, including a call by SLS John in Ft. Worth, then I stopped it and said that SLS was a beaten to death topic on the show and that listeners and I were sick of it. I said no more SLS talk unless there was something new on one side or the other of the SLS issue. At one point I even assigned SLS John a new topic to research and call in about. Let us know with your blog comments, are you sick of SLS discussions on TSS? Do you want to keep hearing them or not? Luis emailed in about having GPS redundancy and backup systems re the European system as an example. Bob had specific ideas about this but thought the better route would be to be able to quickly replace a lost or destroyed satellite. As the segment neared its end, Joe asked about CST and Falcon 9/Heavy & Bob had more to say about ISS modules & Doug asked a series of questions about the benefits of extending ISS to 2028. Don't miss Bob's response. In the second segment, Joe asked about small sats taking over market share from the previous big satellites. Bob provided an interesting short discussion on this topic. SLS John called back about the Falcon Heavy flying and then somehow the discussion focused in on presidential candidates and their space policy in upcoming elections. After a short non-partisan review of what Bob thought might unfold depending on which party wins in November, we moved on to Rosetta and 67 P.

This will help me bring better programming to the audience. We welcomed Michael Listner back to the program for this update regarding specific space law issues and theories. In the first segment of the this 1 hour 48 minute program, Michael talked about the proposed Asteroid Bill in Congress and how to maybe get some limited property rights for asteroid mining by being able to move a small asteroid as in the NASA ARM project. Michael theorized that if one moves an asteroid, its no longer in its natural orbit and then no longer defined as a celestial body. We spent most of the first segment and a good part of the second segment discussing this theory and why it might work. When asked if it would apply to lunar property rights or other space property rights, Michael was clear that it only applied to a small asteroid that could be moved. He also said it would require an administration to endorse such a plan and that it would be difficult to establish as customary and it would certainly be an uphill effort. BJohn and others sent in email comments about this. As you will hear from BJohn's emails which I read on air, not every thought positively about Michael's idea. Michael also talked about other forms of international agreements being much easier to obtain than treaties. He also said the property rights policy battles would be fought diplomatically. In the second segment, we talked about the SpaceX-US Air Force litigation and the AF Motion to Dismiss. Next, we covered the RD-180 rocket motor issue and Michael noted that a new shipment of RD-180 motors had been received. He also said there was new information suggesting Russia might want to expand the mission time for the ISS (http://www.parabolicarc.com/2014/08/25/russia-agree-iss-extension). Property rights and moving an asteroid came back as a topic in this segment & Michael again talked about treaties which he said were top down in policy making while transparency, etc. was considered bottom up policy making. We talked quite a bit about property rights being US one sided and he said that the Asteroid Bill actually enabled those outside the U.S. to put their projects under U.S. law for U.S protection. We moved on to cubesats and oversight/regulation issues. Near the end, Michael updated us on the Code of Conduct in which there should be another draft emerging in the near future. As the program was drawing to a close, I asked Michael for remaining 2014 legal issues that might get a 2014 resolve. We looked forward to early next year & our guest commented on issues involving Russia, China, and ESA. Please post your comments on TSS blog above. You can reach Michael through me or using the email address he gave out on air as the program was ending. Selected by: David Livingston [ stations ], Tue, 26 Aug 2014 16:31:39 UTC

For those listening to archives using live365.com and rating the programs, please email me as to why you assign a specific rating to the show. This will help me bring better programming to the audience. We welcomed Dr. Alan Stern back to the program to discuss New Horizons which is on target for its summer rendezvous with Pluto and new Uwingu projects relating to Mars (www.uwingu.com). During our hour long program, Dr. Stern started with New Horizons and he mentioned the 10 AM PDT, 1 PM EDT NASA press conference today regarding New Horizons passing Neptune's orbit plus it being the 25th anniversary of Voyager passing the Neptune system. The press conference is at www.space.com/17933-nasa-television-webcasts-live-space-tv.html but if you miss it, I'm confident it will be archived. Alan reported that New Horizons was in good health, we talked about the course corrections it has made along its trip to Pluto, plus special events planned for its arrival in the Pluto system. Other topics included the Kuiper Belt and Ort Cloud, dwarf planets and just how many planets are in our solar system per a question asked by a listener regarding his son's science class. BJohn asked questions about the Gaia telescope and comparisons of New Horizons to Dawn and the Rosetta mission. Another listener asked about the New Horizons team and its costs so far. We talked about the need for advanced propulsion and what missions would be most suited for it. Doug sent in an email regarding Pluto, Ceres, and the start of a new era of exploration. Lots of comments and questions about Pluto being a planet as Alan referred to Pluto as a planet. Dr. Stern did go over the differences and similarities with Rosetta, New Horizons and the Dawn Mission and he said the Gaia telescope could not do the imaging Bjorn asked about but that Earth-based telescopes could do a good job in some circumstances s could Hubble. At the halfway point, we switched over to talking about Uwingu and their latest Mars project (see http://uwingu.com/beam-me-to-mars). I mentioned on air about a Space Show contest which would award the winner a message to Mars so if you have ideas for such a contest, email them to me please. I plan on sending a Space Show message to Mars and will post it on the blog. Alan also talked about the program naming Mars craters which will appear on their Mars map which is planned to go to Mars on the Mars One robotic mission in a few years. Before the show ended, a listener asked Alan about the Next-Generation Suborbital Researchers Conference. Please post your comments/questions on TSS blog.

Dr. Rick Linnehan, Friday, 8-22-14 (54.23MB; download) -- Guest: Dr. Rick Linnehan, NASA Astronaut; Topics: Animals in space, human long duration spaceflight. 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.

For those listening to archives using live365.com and rating the programs, please email me as to why you assign a specific rating to the show. This will help me bring better programming to the audience. We welcomed NASA Astronaut Dr. Rick Linnehan to the program to discuss animals and their place in space in history, the present, and the future, plus human concerns for long duration spaceflight. During this one hour program, we stared off by asking Dr. Linnehan for an overview of the role played by animals in space, including looking to the future for animals for agriculture, research pathology work, comfort, & other purposes. We talked about microgravity issues and countermeasures, then I asked specifically about taking chickens to Mars for feed purposes. Our guest talked about the effect of microgravity on chickens and the egg laying process. He said a few times that while we might likely evolve over many years, decades or even longer to having a larger role for animals in space, most of the ideas and concepts today are pie in the sky. We talked about some of the animals that had been and are in space including lab rodents, fruit flies, some small fish and others. Our guest talked about the space acclimation process for animals, including the small fish, and we learned that in many instances the animals acclimate to microgravity faster than humans. Our guest mentioned the need for advanced propulsion for long duration human spaceflight and suggested that Mars was on the edge of the possible using chemical rockets. Rick mentioned some of the other human factors issues such as radiation and psychological challenges. We also discussed astronaut exercise routines and the countermeasure exercise equipment currently being used with efforts underway to redesign the equipment to be more effective and lighter. Several questions came up about private sector humans to Mars missions and crew health. When asked if we could do a humans to Mars mission now or by the early 2020s, our guest said yes but listen to the details of this discussion. Also, with regards to the private astronaut missions to Mars or elsewhere, several questions arose about the conditioning of the private astronaut crew, what microgravity countermeasures and exercise equipment they would have on board, what routines they would strictly follow and more. Our guest was mostly referring to space agency astronauts in terms of our readiness to do human spaceflight to Mars now or the very near future. He was unable to address private astronaut missions or their details because they are unknown. We did talk about gravity and the absence of it in spaceflight, both for humans and animals. Advanced propulsion questions and comments kept coming up during the entire show. To read the balance of this summary review, visit www.thespaceshow.com or http://thespaceshow.wordpress.com.

For those listening to archives using live365.com and rating the programs, please email me as to why you assign a specific rating to the show. This will help me bring better programming to the audience. We welcomed both Dr. Rygalov and Dr. Jurist back to the program for this one hour 39 minute discussion. Prior to starting, I suggested to the listeners that they follow along on the Power Point that has been posted to TSS blog for this program, http://thespaceshow.wordpress.com. Dr. Rygalov used this PPT during his recent ICES conference presentation in Tucson. During the first segment, Dr. Jurist started off with an overview of this work which began with graduate student USAF Captain Sara Ford several years. Dr. Jurist and Captain Ford were on the program to present her thesis work which is available in the archives from Dec. 20, 2009, http://archived.thespaceshow.com/shows/1277-BWB-2009-12-20.mp3. John also talked about Project Moose, www.astronautix.com/craft/moose.htm, and the more recent Red Bull Felix Baumgartner jump from high altitude. John also talked about the parameters his students use when working on this issue. Dr. Rygalov then explained his focus in the research and the analytical effort to describe the major characteristics of a free falling object from high altitude. Our guests talked about hitting dense atmosphere, the impact of the stratosphere and the issue of avoiding a very dangerous flat spin. Describing the process of stabilizing to avoid the flat spin presented an interesting discussion, especially as Dr. Rygalov explained out Felix Baumgartner dealt with the issue. Both guests then talked about the need to attend to the horizontal velocity if one is escaping from a space vehicle but both our guests did say that such an escape was potentially survivable. Doug called in from S. California to inquire about the Red Bull jump and the use of a drogue chute which he believed he saw in a video. John, Vadim and I suggested to Doug that a drogue chute was not deployed because of how Felix controlled the jump, plus we talked about the ground support, technology, and hardware he had to help in the jump. While Doug was talking about the use of a drogue chute with our two guests, I did a quick Google search on the issue and then read a short paragraph from a technology review of the jump at www.extremetech.com/extreme/137521-the-tech-behind-felix-baumgartners-stratospheric-skydive. The paragraph I read explained why a drogue chute was not deployed though Doug seemed to be skeptical. While I had no way to verify what was in the article I was quoting, I encouraged Doug and others to do their own due diligence on the issue. In fact, we should all remember that if there is something we care about or have an interest in, we owe it to ourselves to do due diligence to validate what we are reading or hearing, To read the rest of this summary, visit www.thespaceshow.com or http://thespaceshow.wordpress.com.

This will help me bring better programming to the audience. We welcomed Jeremy Straub and Dr. Ronald Marsh to the program to discuss the NSF Grant awarded the University of North Dakota (UND) computer science department for undergraduate summer work to design and develop mission critical software for cubesats. During the first segment of our 90 minute program, Jeremy Straub introduced us to the UND programs and Open Orbiter. You can read more about these programs by visiting http://webapp.und.edu/dept/our/uletter/?p=48008. Also, take note of the computer science dept. website where program registration will soon be announced, http://cs.und.edu. Jeremy described the programs, Open Orbiter, the undergraduate student participation and expectations, transfer credits, and more. Dr. Marsh, the Computer Science Dept. Head, talked about the role of the computer science department, & why this program was in this department and not Space Studies or the School of Engineering. Listeners asked questions about the program & the possibility of mission critical software development for BLEO cubesats as well as possible commercial applications. We learned that this was an academic program and it might not lead to the actual launch of a functioning cubesat. Jeremy described the additional key activities associated with the grant including a visit to missile system complex, JPL, and a high altitude balloon launch. In the second segment, Charles Pooley called in to promote Microlaunchers and to again talk about the problem with secondary payloads which cubesats rely upon for their launches. Jeremy talked about government sponsored cubesat launch programs including the NASA ELaNA program, ESA programs, the U.S. CubeSat Program, and the University Nanosat Program. In response to the comments by Charles, I talked about the complex benefits students get from working with these secondary payload launch programs and opportunities. One listener asked if computer wise high school students could participate in the program. To do so, students must be enrolled in a college or university. Jeremy also said all the rules would be published when the application process opens up in the near future. We talked about open source work, the program starting in the summer of 2015, that it would be an on campus 10 week program with no upper limit to the number of students that would be accepted into the program. We talked about gender issues and shortages in computer science with Dr. Marsh and we learned that employers do not accept distance learning students as they want the students they hire to have attended on campus classes.

We welcomed back Chris Carberry, Executive Director of ExploreMars.org and for the first time Joe Cassady to discuss current and new ExploreMars.org projects including the ExoLance Mission and the Time Capsule. During the first segment of this 90 minute program, Chris provided us with a brief overview of ExploreMars.org, then he got into the specifics of their new project, ExoLance. For more information about it and the crowd funding financial program, see www.indiegogo.com/projects/exolance. Both Chris and Joe spent most of this segment with the details of this mission which will flyto Mars on an existing NASA or ESA Mars mission in the 2020s, dropping up to six tungsten penetrators loaded with life detection experiments to penetrate the Martian surface by up to 1-3 meters. Our guests answered many emails as well as phone questions including specifics about the penetrators, the locations they would search, the tungsten penetrators serving as ballast on the main spaceflight missions, the impact velocity, and much more. Chris and Joe several times referenced the work of Dr. Gil Levin for his labeled release (LR) experiments on the Viking missions, plus the work of Dr. Chris McKay at NASA Ames. Both are key to designing the mission and scientific instrumentation for the penetrators. I hope you find this detailed discussion as interesting as I found it. In the second segment, we talked about other ExploreMars.org projects including the student led Time Capsule. For more information, visit www.timecapsuletomars.com. According to the website, the Time Capsule project sends to Mars digital messages from tens of millions of people from all corners of Earth in the form of text, images, audio and video clips. This will Enable tens of millions of people from every country on Earth to upload their pictures, short movies, text messages and other digital media to the time capsule for about $1.00 for 10 mb. Joe and Chris described the project, the student leaders behind it, and they invited all to participate. Later in the segment, our guests talked about the next Humans2Mars conference scheduled for early May 2015. They also talked some about this year's conference and the many people that attended it plus the thousands of others around the world who saw it via streaming. As you will hear, more than a thousand schools worldwide logged in to see the speakers as well. Clearly, going to Mars gets people's attention around the world like nothing else in the space field. We got an email about possible ITAR issues with the crowd funding program and I asked our guests for Plan B-- to see the rest of this review, visit www.thespaceshow.com or http://thespaceshow.wordpress.com.

I asked Dr. Levin about criticisms to the findings published in his paper and he said the controversies centered around liquid water being on mars and for fossil references. Gil also talked about the difficulty in getting NASA information on Mars mission experiments and his use of the Freedom of Information Act. He also told us stories of his efforts to propose Mars life detection experiments with other national space agencies. His theory as expressed in his latest paper is that there are microorganisms on Mars with a similar biochemistry in water similar to what is on Earth. We received lots of email questions from listeners ranging to questioning the significance for us here on Earth in confirming microbial life on Mars, to the impact in our science, academic and religious communities. One interesting email came from Joe in Denver asking if Gil was maybe too close to his own research thus possibly skewing his objectivity. Gil brought this up near the end of the second segment as well but listen to how he responded and the challenge he put out to listeners and others interested in this issue. You decide if you think he is too close to life detection on Mars to be an objective scientist. Near the end of the first segment, Doug emailed in wanting to know if microbes in the rocks could be imaged by a microscope instrument on a rover. He was not satisfied with Gil's response so he asked it again as we started the second segment. Before we ended the first segment, we talked about possible reasons why some life detection experiments that could be done by Curiosity had not been done or at least not reported on were they done. In the second segment, aside from Doug's modified repeat question about microscope image detection, Gil talked about the newer LR analysis using complexity analysis by a scientist at Sienna University. He also mentioned updated analysis by Dr. Joe Miller at USC. Another listener again asked about challenges to his Mars Society paper and Gil listed the three mail areas of challenge for us to consider.
