This will help me bring better programming to the audience. We welcomed Phil Pressel to the show to discuss the Hexagon KH-9 spy satellites cameras used in the Hexagon program 1971-86. During the first segment of this 100 minute program, we had a technical glitch in the first fifteen minutes so we restarted the program working off my notes. You will hear the details of this in the special recorded message I used as part of the replacement program introduction. Mr. Pressel was the project engineer in charge of the design of the formerly top secret Hexagon KH-9 camera as part of the Hexagon program which was finally declassified in 2011. Phil prepared a Power Point presentation with important Hexagon KH-9 photos so you need to access this presentation during this program. You will find the PPT on The Space Show blog, http://thespaceshow.wordpress.com for this program and the Feb. 6, 2015 date. Again, you need to be following along with Phil (he jumps around with different pictures and slides) to get the maximum benefit of this program and to understand Hexagon. Most of the first segment Phil explained the challenges, the mission, and many of the technical aspects of the two cameras, the special film developed by Kodak, and the retrieval process for the film. He focused on some of the specific slides showing us the components of the camera and how it worked, plus he described the workings to us in quite some detail. Near the end of the first segment, questions started coming in about controlling the cameras, telemetry, and more. In the second segment, Phil said the key to the system was the Twister which he explained to us using slide #23. Michael Listner called to congratulate Phil and the team for this project and their service to the nation. After Phil and Michael talked and Phil described the Twister, Dwayne called wanting to know how big of an area was captured by the cameras. As you will hear, it was a big area. They talked about the Push Broom Method of scanning which Hexagon used to some degree, its polar orbit and the huge amount of imaging done by the satellite. Phil also described the process of getting the hardware to Lockheed, & the vibration and shake tests done with the camera and the satellite. BJohn wanted to know how the Soviet spy cameras of the day measured up to Hexagon. Both Dwayne and Phil offered their perspectives and both did not think the Soviets could match Hexagon but not much data has been released on this by Russia. Phil talked about their security and even keeping silent about their real job with their families. Read the rest of this summary at either www.thespaceshow.com or http://thespaceshow.wordpress.com.

Please note that audio and transition issues are a result of copying the John Batchelor broadcast & are not within my control as they stem from the Batchelor studio. John Batchelor and I welcomed Dr. William (Bill) Borucki back to the show to discuss the recently announced discovery of the small five planet system 11.2 billion years old, Kepler-444. This is approximately 2.5 times older than the Earth. We discussed the exoplanet search, rocky planets and their early formation, the surprises contained within the discovery of Kepler-444, and life detection in the habitable zone. As it turns out, the five small planets orbit their sun in 10 days so they are far too hot for life. However, Dr. Borucki did at one point during our discussion estimate the number of planetary candidates that were possible in the habitable zone. One can see Kepler-444 with binoculars so I asked our guest where to look to find it. He also said it was a triple star system! Among the surprises included the discover of dust and metal that early and the discovery that stars formed so very early at all.
Please post your comments/questions on TSS blog. You can email Mr. Batchelor or Dr. Borucki through me at drspace@thespaceshow.com.

This will help me bring better programming to the audience. We welcomed Dennis Wingo back to the show to discuss his outstanding article, "The Quagmire of The Apollo Space Program" (see https://denniswingo.wordpress.com/2015/01/18/the-quagmire-of-the-apollo-space-program). During the first segment of our 1 hour 58 minute discussion, Dennis started out by telling us about his interest in the subject and why he decided to research and write the article in question. He methodically took us through many of his resources and research methods, highlighting a few resources along the way that were instrumental in his analysis and coming to his conclusions. One resource he discussed was Ralph Cordiner, the former General Electric CEO. He also cited many examples in support of his conclusions so I strongly urge you to read his article in association with listening to this program. He also cited the references indicating that entrepreneurial activity was not what they wanted to happen as an outgrowth of Apollo as it was meant to be a national prestige program. Given the dysfunction with government, Doug emailed in asking about public/private partnerships. Dennis offered qualified support for them but listen to what he had to say on this hybrid model. Dennis then talked about R&D tax credits but for start-ups, the Zero G Zero Tax program was better. Much of our ongoing discussion in both segments focused on aspects of the Zero G Zero Tax concept. Doug sent in several emails asking about Zero G Zero Tax before the segment ended. In the second segment, Charles Lurio called and wanted to know if Pro Space or any organization would be pushing for Zero G Zero Tax this year. Dennis did not think so but it might happen. In response to other questions, Dennis explained how Zero G Zero Tax might work because it would only be applicable for new businesses, not existing businesses. Don't miss this explanation. Later, Doug asked if we were running out of resources on Earth that might cause a need for space resource development. Dennis had much to say on this, especially regarding rare earth elements. This prompted a call from Kristophr about thorium as a reason the US does not develop its huge rare earth element resources while China does develop theirs plus they stockpile the thorium for future use. Dennis and Kristophr had a very interesting conversation about this topic and I assure you, you do not want to miss it. As the segment advanced, Dennis spoke to the commercial opportunities arising from the ISS which he said were very important.

This will help me bring better programming to the audience. We welcomed Dr. Cameron Smith to the program to discuss interstellar spaceflight and our distant human future. You can see his lecture on this topic, "Interstellar Voyaging: An Evolutionary Transition" at www.youtube.com/watch?v=CprziVZHqBk. During the first segment of our 91 minute program, we talked about the biological and cultural challenges involving interstellar flight. When asked why he was interested in this field and doing research in it, he talked about how important it was to influence for the good our distant human future. He talked about human success over time in adaptation as humanity is adaptable. He then spoke to the need for species insurance. John in Florida called in with Mars archaeological questions, wondering what may be left of a civilization after a billion years or so. We also talked about models from Earth archaeology around the world in places like the Middle East. Our guest said there were plenty of unknowns in trying to extrapolate Earth archeology to Mars. Another listener asked about robots versus humans, a topic our guest had much to say about. The bottom line is that humans are still a much better tool but robots are also needed. We talked about ways to influence policy makers and the importance of influencing the public. You might be surprised by some of our guest's comments. We talked about Mars and he said it was a good first step. He was then asked about the Moon as a first step. He cited a comment by Dr. Zubrin suggesting that regarding the Moon, "the cops are too close!" Listen to how our guest explained this comment. I asked several questions about student interest in interstellar spaceflight. Other topics in this segment included extra terrestrial life and questions about Cydonia which our guest said he had studied in detail and concluded it was not from a past civilization. In the second segment, Cydonia questions continued to come in and Dr. Smith elaborated on his studies and conclusions. The Swedish website Glanta came up as our guest had an article published on the site. Their English language site is http://glanta.org/?page_id=2. The ISS came up with listener questions and our guest was critical of it since it still does not have closed loop environmental and life support. The field of exobiology was discussed as was the need for low cost space access. Paula in Denver asked about the need to be inspiring and to inspire students and others regarding space, interstellar flight, and our distant human future. Cameron said we needed to start with kids and that it was important to do so. He also spoke to the need to make sure our students have and know how to use the skills of critical thought.

Follow along with this important website. www.cislunarone.com/lunarbaseone.htm. Be sure to click on the link in the upper left hand corner to download the Lunar Base One Reference Material. In the first segment of our 2 hour 1 minute discussion, Doug focused on introducing us to his Lunar Base One concept and Lunar Cots. To follow this discussion, make sure you go to the Lunar Base One website per the above URL as he follows the information on that site for our discussion. During Doug's discussion, he took calls and emails from listeners on a wide range of associated topics, questions, and comments. Listener questions covered telerobotics, wireless power transfer, artificial gravity & the use of a centrifuge at the base, wired power as in missile wire, laser beam power, battery usage, lunar dust, radiation, water, a lunar greenhouse, and check lists re solar panels, propellant, fuel cells, radiation, and more. In the second segment, Eric called using a cell in Florida to discuss robotics over humans. Later, Doug was asked if returning to the Moon would divert resources needed for going to Mars, the moons of Mars, or even an asteroid. Don't miss his response to this question. BJohn asked about line of site communications with Earth or if there would be a need for lots of communication satellites. Doug and John from Ft. Worth had an interesting discussion on several key points, then Doug spoke to lunar tourism, the transportation needs, then I asked him about changing space policy. Specifically, I asked what he would say before Congress re changing our policy as to why the Moon were he to testify before both House and Senate committees. Give your ideas on this on the blog because no matter how cool the technology and engineering may be, without a policy to go back to the Moon, most likely nothing will happen. Rasmus called from Toronto suggesting the use of mylar over a small crater. You don't want to miss this discussion. As the show was drawing to a close, Doug spoke about his return to the Moon track at this year's Space-Access Conference which will be in Phoenix in late April. He finished up his discussion talking about artificial gravity, the use of a long arm centrifuge on the Moon running at about a 5.4 RPM by the lunar team. He also spoke about inflatables and what he learned in his discussions with the University of Maine professor. Please post your comments/questions on The Space Show blog above. You can reach Doug at the address on his website or through me. Selected by: David Livingston [ stations ], Mon, 02 Feb 2015 17:51:34 UTC

This will help me bring better programming to the audience. We welcomed Dr. Edgar Bering to the show to discuss the "Mars Rover Model Celebration and Competition " and his undergraduate student balloon projects to study the Northern Lights and more. During our one segment one hour program, we focused the first half on the Mars Rover Celebration aimed at both elementary and middle school students while in the second part of the segment, we talked about Dr. Bering's balloon projects and even a possible cubesat to Mars project. Dr. Bering explained the Mars Rover Model competition which has the students doing a six week Mars course in preparation for their rover mock-ups. You can learn more about this competition at their website, http://marsrover.phys.uh.edu/about.php. Dr. Bering took us through the requirements, differences in the competition for the elementary school students compared to the middle school students and he even responded to a question as to how to get a six week Mars curriculum into the school program. He said the rover categories included a free form model rover made of "stuff" plus a solar power model, and for the older students a radio controlled model made from the parts of an RC model car. Our guest would asked if the model rover program would work for going to the Moon, not just Mars. He said yes but don't miss his full reply. In the second half of our segment, we talked about his high altitude undergraduate student balloon projects to study the Northern Lights and its effect on the upper atmosphere. He will be taking his students to Alaska to see the Northern Lights and to conduct the balloon studies. He talked about the significant improvements in miniaturizing with the needed electronics, sensors, and cameras, plus today's high reliability of these components. He point out that instruments capable of doing the work of today's instruments would have weighed around 120 lbs. in previous years. Now they are shooting for a total mass for the instruments of less than 6 lbs for doing meaningful science. In 1985, the ultra-lute instrument package would have been 50 lbs. Dr. Bering was asked if his students did cubesat projects and he told us about a possible Mars cubesat project. He was confident they could get telemetry back from Mars with a cubesat and talked about new antenna improvements. Toward the end of our discussion I asked if he had any stats on students doing these programs from elementary and middle school and if they went on to careers in space, science, etc. Don't miss his response. Please post your comments on TSS blog above. You can reach Dr. Bering through the Mars Model Rover website or me. Selected by: David Livingston [ stations ], Sat, 31 Jan 2015 17:29:48 UTC

John Batchelor and I welcomed Michael Listner, ATTY, back to the show to discuss the recently announced settlement in the SpaceX vs. USAF litigation around the block buy, SpaceX certification, etc. Michael took us through the origins of the law suit filed last year by SpaceX, the various motions to dismiss that were filed and the eventual settlement talks by both parties and the settlement reached about a week ago. Michael pointed out that nothing changed regarding the existing block buy of 36 core sole source contract buys awarded to ULA. The settlement did arrange for assistance to SpaceX to earn certification and for future bidding. Michael also provided us with his opinion as to a possible winner in the litigation or was there no winner. See what you think. Please post your comments/questions on TSS blog.

This will help me bring better programming to the audience. We welcomed John Powell back to the show for updates on JP Aerospace (www.jpaerospace.com). During the first segment of our 1 hour 44 minute program, John started out talking about their UAE mission, crossing the desert in the UAE and raising the UAE flag to 102,000'. You can see the video of this recent JP Aerospace event at www.frequency.com/video/uae-flag-in-space-by-al-hilal-bank/212906510?cid=5-8124. Next, John took us through an overview and set of updates for their Airship to Orbit (ATO) venture. He began this by talking about a series of tests they have done and will be doing that will eventually enable ATO. Much of this information is on the JP Aerospace blog at http://jpaerospace.com/blog. John went into some detail to describe the tests, especially those that will lead up to eliminating most of the drag at altitude for ATO. Listeners asked several questions via email about the size of the airship, space diving from Dark Sky Station, and then Charles emailed in a note about air density at 140,000 feet, the altitude of the proposed Dark Sky Station. For the balance of this segment, John explained the different stages of the ATO program, some of the hardware that was needed, and the JP progress to date. Greg Cecil called in as a customer of JP Aerospace. He told us what it was like being a customer, the positive impact on his students with JP programs such a MiniCube, plus he emphasized how important it was for John to be an out of the box thinker looking for alternatives to establishment problems such as the high cost to orbit. In the second segment, John continued talking about the ATO program plus ion engine development. John from Florida called in and went through the basics of how the program was to work. During this discussion, speed dynamics for their winged shaped vehicle were discussed, plus JP said they were working on getting power from batteries. This led to a discussion about JP developing MHD technology which you can see documented on their blog. I asked JP for the biggest challenges and he said engine work, then described the specific challenges in their engine work. He also said it was a challenge to scale up to large vehicles from small vehicles. Tim called in to suggest a reentry system. JP was ahead of the game on this one and described some of the work they were already doing re these systems. Scott sent in an email asking JP how one volunteers to work for JP Aerospace.

To find out more about Dawn, visit http://dawn.jpl.nasa.gov. Also check out Dr. Rayman's blog The Dawn Journal @ http://dawnblog.jpl.nasa.gov. Visit the DS1 site & archives by Dr. Rayman @ http://nmp.jpl.nasa.gov/ds1. During the first segment of our 91 minute program, Dr. Rayman introduced us to the Dawn mission which first went to Vesta & is now closing in on its second destination, Ceres. We talked about the mission being specifically chosen to visit both Vesta & Ceres & that Vesta data is still undergoing analysis. Dr. Rayman described Vesta's Cornelia Crater 300 miles in diameter formed by an impact about one billion years ago. We also talked about Vesta meteorites on Earth. Dwayne called regarding competing theories about Ceres, planets having changed positions at one time, & Dawn mission limitations. Perry wanted to know what information the team most wanted to get from Ceres. Dr. Rayman said they wanted to know basics such as what it looks like, what it was made of, ice, etc. Other listeners wanted to know about Ceres compared to Mars access. Here, Dr. Rayman had much to say as the subject came up again in the second segment. Doug wanted to know about the large bright spot on Ceres plus other questions. In the second segment, Dr. Rayman told us about his Dawn Journal (blog) per the above URL. I asked our guest if he thought of Dawn & other science missions as competitive with human spaceflight missions. Don't miss his reply as I believe it was very special. BJohn sent several emails asking for Dr. Rayman's favorite targets, especially for future missions. He also asked about using nuclear power rather than solar. Our guest described the solar arrays & why solar was chosen for Dawn. Ion propulsion came up & was a major discussion topic for the balance of our program. Dr. Rayman described how ion propulsion worked, why it used a slow but steady acceleration, & its advantages over chemical propulsion. Matt asked about RTG development for future missions . Doug sent us another question based on the low Ceres gravity & landing on Ceres to pre-position supplies in advance of a crew. Our guest pointed out it was far more complicated than Doug implied given that the Ceres orbit was tipped more than 10 degrees from the ecliptic. Make sure you hear this explanation. Among the many questions Matt asked, he wanted to know about the German component of the Dawn mission. As we approached the end of our show, Dr. Rayman gave us a preview of what to expect as we get very close to Ceres, gradually getting as low as Earth & ISS. Please post comments/questions on TSS blog above. The guest, callers, & those sending emails can be reached through me.

During the first segment of our two hour seven minute program, we took several calls starting with John in Florida who wanted to talk about early Mars colonization, one way Mars trips and similar topics. He wondered about buried Martian ruins deep under the ground and I drew an analogy to archaeological digs here on Earth in finding towns and early civilizations buried on top of one another far below the surface of the Earth. John from Ft. Worth called in to talk about the Al Worden interview in which Al did not think there was any reason for returning to the Moon. You can read the Worden interview at www.dw.de/apollo-15-command-module-pilot-alfred-m-worden-nasa-took-a-step-backwards/a-18211468. I also asked John about the release of thousands of UFO documents, www.usatoday.com/story/tech/2015/01/19/air-force-ufo-files/21985651. John and I then returned to discuss more about the Worden interview, his comments on the shuttle, the ISS, Saturn V and more. In the second segment, Michael Listner called to update us on the settlement of the SpaceX Air Force litigation. Michael summarized the mediation and the settlement details for us. Dr. Doug from S. California called to talk about a variety of topics including radiation. He referred to an Al Globus article regarding his view on shielding requirements. You can read Al's article here: http://space.alglobus.net/papers/RadiationPaper2014.pdf. Doug also talked about a permanent base on the Moon and his Mars Return Option. Dwayne was the next caller and he spoke of John Logsdon's upcoming book on Apollo and the Nixon space policy. He talked about all the budget cuts and slashes back then and how they negatively impacted the program. Dwayne also talked about the nuclear thermal rocket and the fact that it can't go active until it out of Earth orbit. Adrian sent in an email about radiation debris putting satellites at risk. Here is the older NY Times article he sent me: www.nytimes.com/1995/02/26/world/radioactive-debris-in-space-threatens-satellites-in-use.html. Tim called to debunk the Mars crew living in a tuna can analogy and instead wanted to compare it to submarines. He got some pushback on his submarine analogy. Earlier, Jon from NJ had sent in a note about the SpaceX satellite plans & what this may mean for SpaceX. Please post your comments/questions on TSS blog. You can reach any of the participants through me. Selected by: David Livingston [ stations ], Mon, 26 Jan 2015 17:46:02 UTC
