During our 11 minute plus discussion with Dr. Don Yeomans of the NASA Near Earth Object Program Office at JPL, we talked about the 17,500 mile approach to Earth of Asteroid 2012 DA14. This asteroid will be this close to Earth on Feb. 15, 2013. We discussed the asteroid's orbit, possible collision with our satellites, and how we might deflect or mitigate the damage of an object this size that might be headed for Earth impact. This particular asteroid is probably made of rock and has a 45 meter diameter. Dr. Yeomans also talked about the search for potential NEOs that could impact the Earth, breaking the search down by the size of the space object. Our guest suggested the best viewing spots for trying to see Asteroid 2012 DA14 but unfortunately the sites are not in the U.S. To really see it, one would need binoculars or a telescope.

Zac Manchester, Tuesday, 2-5-13 (43.24MB; download) -- Guest: Zac Manchester. Topics: Zac's KickSat project, cubesats, crowd-funding, & more. 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.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information. We welcomed Zac Manchester to the program to discuss his KickSat CubeSat open source mission using 200 Sprite ChipSats. You can learn more by visiting www.kicksat.net, www.spacecraftresearch.com and http://www.kickstarter.com/projects/251588730/kicksat-your-personal-spacecraft-in-space. From these websites you can visit the KickSat wiki as well as the KickSat blog. We started our discussion with Zac Manchester with his providing us with an overview of his KickSat project and Kickstarter as a tool to fund some types of space ventures. Zac talked about launches being provided by the NASA Educational Launch of Nanosatellites (/ELaNa) program plus the lack of traditional financing which caused Zac to give Kickstarter a try. The KickSat team started out wanting to raise $30,000 but instead raised nearly $75,000. He had much to say throughout both segments regarding crowd-funding and the use of Kickstarter. Zac also described the cubesats and the Sprite ChipSats. He talked about the importance of reducing the size of the unit and what this meant for mission design, propulsion, technology advancement, lower launch costs, and more. Several listeners emailed him questions including space debris questions since the 200 Sprite ChipSats would have a short life expectancy and then return to Earth. He said all would burn up in the atmosphere but he also talked about future missions where the units would float back to Earth as would a piece of paper. Technology advancement for this to happen must take place but he said it was certainly plausible. Other issues discussed in our first segment included secondary payments and payload integration. Regarding payload integration, he said their project goes to Cal Poly for peapod integration and then to the Cape from Cal Poly for vehicle integration. Cal Poly does the peapod integration for academic cubesat projects. A listener saw the project plans on one of the websites and inquired about making the hardware or buying a kit from Zac's group. As you will hear, the project is open source and people are encouraged to buy the off the shelf parts and make their own unit. Zac mentioned several online stores where the parts could be bought. We talked about the difficulty in getting a launch for a stand alone cubesat someone might build. In the second segment, we took a call from Charles Pooley who talked about building a small launchers to get away from secondary payloads and potential launch delays we he said were the barriers to this industry. Check out www.microlaunchers.com for more on the Pooley idea. Zac then told us about the March 16 workshop at the Hacker Dojo in Silicon Valley on how to set up KickSat ground stations. Zac described the ground station using Ham bands and suggested the cost would be around $200.00. Another listener asked Zac for his background & how he got interested in space & a cubesat project. Zac had much to say about the academic research that inspired him as both a Cornell undergrad and masters student. Please post your comments/questions on The Space Show blog above. You can contact Zac through his project websites and blog. Selected by: David Livingston [ stations ], Wed, 06 Feb 2013 17:11:30 UTC

Michael Laine, Monday, 2-4-13 (61.54MB; download) -- Guest: Michael Laine. Topics: Lunar space elevator updates. 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.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information. We welcomed back Michael Laine for LiftPort Group updates regarding the lunar space elevator. For more information, visit www.liftport.com. Michael started our two hour discussion talking about his very successful Kickstarter campaign last year. LiftPort started the campaign asking for $8,000 but raised $110,000! During this first segment, Michael talked about the plans to use the $110K, the experiments LiftPort would do and why additional funding was needed to advance the lunar space elevator project. I asked Michael lots of questions about the lunar space elevator market, his time table for transitioning away from being a Power Point project, & the LiftPort labor force. LiftPort is mostly volunteer labor. For now it is working on tether and balloon experiments. We talked extensively about using Kickstarter and even talked about the tax consequences for Kickstarter revenue. Michael did say that he thought the project would be a private project in that government would not be a major supporter, if at all. Michael then talked about his fact finding global missing seeking new financing and partners after the Kickstarter campaign. He had much to say about his visit to Iceland and the company CCI Games. When pressed, Michael suggested 8 years from last August to completion. Listen to the details supporting this timeline. Michael also outlined four areas needing resolve to move the lunar elevator project forward. In our second segment, Michael described more of the elevator project, including the use of EML1 and why & how the elevator ribbon would work, including its logistics from EML1 to the lunar surface and EML1 back toward Earth. He also talked about their lunar surface elevator contact point on Sinus Medii. A listener asked him about the Google Lunar XPrize & Michael told us how a GLXP mission could benefit the LiftPort project. Also in this segment, we talked about costs. Michael estimated about $800 million for a robotic mission and maybe up to $1.2 billion for three astronauts roughly every three weeks. He compared these costs to the cost of shuttle launches and flights to the ISS. When asked about lunar markets that might economically justify the lunar elevator, he talked about the potential of HE3 mining and new uses for the material here on Earth, plus lunar SSP and solar panel manufacturing. Alex asked Michael to be specific about the transitional steps from Power Point to the beginning of a systems engineering project to develop the elevator. Emory emailed in more questions about tether use, Tim called (sorry for phone line issues on Tim's call) regarding tethers and more. David Ben wanted to know about the Falcon Heavy and I expanded that to include SLS. A question came up about LiftPort's interest in a Mars space elevator. Our discussion concluded with Michael suggesting that Kickstarter & similar crowd source funding organizations will play a bigger & more important role in funding space ventures in the future. Please post your comments/questions on The Space Show blog. Michael can be reached at info@liftport.com. You can also subscribe to the LiftPort free newsletter from their website.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information. We welcomed Nino Pollizzi back to the program to discuss his STEM outreach educational program, Rocket Science Tutors (www.rocketsciencetutors.com). Rocket Science Tutors is a program for middle school students, currently in the Santa Ana school district in Orange County, CA, to teach STEM subjects to students after school. During the first part of our program, Nino described Rocket Science Tutors in detail, starting with the all volunteer staff from within the industry and the University of California Irvine (UCI) graduate students. He described the after school problem, the need for a teacher advisor, parental approval, and the demographic of the kids enrolled in the program. He said the program has been in place for eight years and they are open to expanding it to other schools and districts around the country. In fact, he received listener questions about expanding it to St. Louis and Los Angeles. Nino said the program was ready to be replicated. He has invited interested parties to contact him about this. We talked about some of the programs and projects taught in their classes including pulleys, basic electrical systems, Ohm's Law, parabolas, the need for algebra, and more. In our second segment of this 1 hour 42 minute program, we talked about the DC-X as Nino worked on that program when he was with McDonnell Douglas. DC-X is having their 20th reunion this August in New Mexico, an event which Nino talked about during our discussion. We also talked about the DC-X vehicle, its problems, the plans to scale up the demo to the two more advanced models, and ultimately its cancellation and the NASA selection of the X-33. Nino also took some questions about the possibility of a single stage to orbit vehicle with a useful payload. If you have comments/questions for Nino regarding this program, please post them on The Space Show blog. You can also contact Nino using www.rocketsciencetutors.com/contactus.php or directly by email at nino@rocketsciencetutors.com.

Alan Steinberg, Friday, 2-1-13 (52.62MB; download) -- Guest: Alan Steinberg. Topics; Protecting our space assets, weapons in space, space policy and public opinion. 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. We do not permit the commercial use of Space Show programs or any part thereof, nor do we permit editing, YouTube clips, or clips placed on other private channels & websites. Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information. We welcomed Alan Steinberg to the program to discuss both is latest Astropolitics article, "Weapons in Space: The Need to Protect Space Assets," and his 2011 Space Policy article, , "Space policy responsiveness: The relationship between public opinion and NASA funding." Both of these articles are available for purchase by using Google the full title of the article. During the first half of the program, we focused on Alan's Astropolitics article. As you will hear, the issue of protecting our space assets is not an easy one to address or solve. Furthermore, as Alan and listeners suggested, the response the U.S. might make to an attack on space assets is unclear, especially if the attacking party or nation had an excuse, said it was an accident, or denied intentionally doing the deed. Alan and listener Michael defined the term space weapon and Michael provided us with the PPWT proposed treaty language defining space weapons. Alan had much to say about protecting space assets and weapons in space in the context of the U.N. treaties. We talked about U.S. as well as international enforcement here and in other countries. Space debris was discussed, especially in light of the difficulty in diplomatic action leading to tangible action against a debris causing country or party. Also discussed was government being responsible for commercial space assets under its flag. In the second segment, we mostly talked about Alan's 2011 Space Policy article, "Space policy responsiveness: The relationship between public opinion and NASA funding," although many listeners via email and the phone kept returning to the space weapons topic. Alan took lots of questions about the role and impact on policy of space advocacy and as you will hear, its not easy or clear to pin down. Alan had much to say on how best to influence members of congress but was clear in pointing out that space advocacy does not have the numbers of the larger and more powerful lobbying groups that are far more effective in influencing policy than is the space community. Another of his points focused in on the significant influence of the aerospace industry as compared to space advocates and enthusiasts. We also learned from his concluding paragraph that when researching this issue, "research on what influences space policy attitudes and even space policy public opinion is in short supply." In addition, we learned that while Americans like our space program and NASA, they don't have a good understanding of it, the actual amount of funding NASA gets in relationship to the budget, and that their liking of the space program simply does not translate to more funding and more programs. Please post your comments/questions on The Space Show blog. If you want to contact Alan Steinberg, you can do so through drspace@thespaceshow.com.

Doug Messier, Tuesday, 1-29-13 (55.43MB; download) -- Guest: Doug Messier. Topics: Spaceport America and Virgin Galactic informed consent, liability, & contract issues per www.parabolicarc.com & much more. 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.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information. We welcomed Doug Messier back to the program to discuss his reporting on Spaceport America and Virgin informed consent issues and possible contract issues. We also talked to him about his management of Parabolic Arc, his possible expansion of the blog and even accepting guest contributors. Check out his reporting and stories at www.parabolicarc.com. Our first subject was on Spaceport America and Virgin starting with Doug's most recent post about possible Virgin rent payment disputes followed by the informed consent issues which may now have been resolved through negotiations with Virgin, the NM legislature, and NM trial attorneys. We took listener calls and emails and as it turned out, the spaceport and Virgin story was controversial with listeners all over the board on these issues ranging from Charles who believes the spaceport and the industry are way ahead of their time to others who believe success will definitely prevail for the spaceport, Virgin and the industry. Another issue discussed in the first segment was the hybrid rocket engine, possible Virgin problems with it, and related items. Doug shared his information with us on the subject and provided us with a brief history & overview on the hybrid engine. We talked about powered test flights and the difficulty in doing these ventures given they always seem to be about two years away from operations. In the second segment, Doug told us about activities at the Mojave Air and Space Port including the construction for Stratolaunch. Somehow we ended up again discussing hybrid engines and informed consent. Doug was asked about Virgin and XCOR differences and he spoke as much as he could about the Lynx but said he was under NDA with XCOR as he is working on an XCOR book. He seemed to favor the XCOR approach. We talked about his future plans for Parabolic Arc. He is thinking of broadening it to other areas and accepting guest contributions. I asked him about his visits to see the ATK five segment SRB tests and his thoughts on solids, ATK, etc. He had much to say about it and SLS. He continued talking about Mojave, I asked him if he had ever seen the Orbital L1011 and he told us about his tour of it and hearing Bill Weaver speak about his SR-71 breakup and survival. A listener asked him about Interorbital out of Mojave, we talked about Dream Chaser, and more. If you have comments/questions for Doug, post them on The Space Show blog. You can email him through me at drspace@thespaceshow.com. Selected by: David Livingston [ stations ], Wed, 30 Jan 2013 18:51:19 UTC

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information. We welcomed Dr. Erik Seedhouse back to discuss his latest book, "Pulling G: Human Responses to High and Low Gravity. I strongly recommend this book as it is a terrific resource on the subject of G-force on the human body. If you buy it using this URL from Amazon, Amazon will make a contribution to The Space Show: http://www.amazon.com/Pulling-Responses-Gravity-Springer-Popular/dp/1461430291/ref=onegiantlea20. Our 1 hour 42 minute discussion was in two segments but as our topics overlapped segments, there will be no part one and part two for today's program summary. Dr. Seedhouse began the discussion talking about the different types and sources of gravity on the human body. This included acceleration, lateral, reentry, vibrational, and more. We talked about helmet restraint issues, Formula One race cars and taking corners at high speed producing a high lateral G force, jet fighters, rocket flight, roller coasters, and more. Erik went over the proposed flight profile in g terms for Virgin Galactic and other proposed vehicles. He also talked about centrifuge research and findings with the general public at the NASTAR facility. He then switched to g-load force, fighter pilots and the Anti-G straining maneuver and breathing that they do to help counter excessive g's. Suborbital flight came up and here, Dr. Seedhouse had much to say given the small amount of suborbital human spaceflight history. We also talked about bone loss and density issues, osteoporosis, and obesity. Erik said the best physical profile for resisting high g force was short and stocky. The worst was tall and thin. Don't miss his explanation for this. He also said smokers do better in high g's over nonsmokers. Erik got lots of question about the Bill Weaver SR-71 ejection. Then he mentioned the Armstrong Line and said above that point, blood boils without a pressure suit. Erik also talked about orthostatic intolerance (OI) in the context of g tolerance. He talked about professional astronaut training for suborbital missions such as with Astronauts4Hire. We then discussed the financial problems hitting the Canadian aerospace industry with layoffs, closures, and the possible sale of valuable space hardware. Listeners wanted to know about anti g countermeasures, if any, and laser eye surgery was discussed although Erik said it was no longer a problem. Please post your comments/questions on The Space Show blog.
