We welcomed both Dan Freyer and Tabor MacCallum to discuss the upcoming Space Tech Expo to be held in Long Beach, CA from April 1-3, plus Tabor told us about World View near space balloon rides and their work on HSF missions to Mars.  There was only one segment for this one hour program.  We started with Dan who gave us an overview of the Space Tech Expo (www.spacetechexpo.com).  He talked about the free program, the paid program, the exhibits, and the B2B focus of the conference.  We went through the paid Expo agenda which you can find at http://www.spacetechexpo.com/conference/conference-program-2014.  Dan stressed the business 2 business focus of the expo, talked about the mix of aerospace, defense, military, satellite, launch vehicle companies and executives that will be attending. We also talked about the exhibitors and their ability to tell attendees about their products and services.  Taber jumped in to talk about the World View near space balloon rides which they will be talking about at their booth #4042.  Dan also went over the conference logistics and fielded several questions asking about NewSpace representation at the expo, the possibility for students & interviews, networking opportunities, lunches with the paid program, plus more.  Later in the segment, Tabor received several email questions about his work on the life support systems for human spaceflight missions to Mars.  He talked about going to Mars, Inspiration Mars, Mars One and a stepping stone approach that might include going to an asteroid and the moons of Mars.  We discussed the possible need to first go to the Moon to learn how to go to Mars.  We talked about closed loop systems, radiation & microgravity issues, plus the complexity of landing large payloads on Mars. We concluded our hour discussion by reviewing the Expo logistics, registration on their website, and the strong business focus for this conference.

We welcomed back Dr. Doug Plata to the show to discuss his selected trades for his Cis-Lunar One Transportation Architecture.  You can find Doug’s Choices of Selected Trades document on The Space Show blog at http://thespaceshow.wordpress.com under the summary for this particular program and date.  In the first segment of our 2 hour 6 minute discussion, Dr. Plata started out giving us an overview of his project, mostly by reading to us the “Overview of the Cis-lunar One Architecture” which is part of his document on our blog.  In addition, Dr. Plata wants your feedback regarding his project, including constructive criticism.  You can email Dr. Plata at dougspace007@gmail.com.  After discussing the project overview with us, Doug started addressing the trades listed in his document.  We started with Trade 1 Launcher.  Doug went through all of his considerations for launchers, was clear that he was not ruling any particular rocket out of the question.  Make sure you note his “Table1: Choice of Launcher & Fuel.”  The led us to discussing payload issues for the mission.  Also note that Doug has named his lunar craft the Condor upper state LL as you will see that name show up throughout our discussion.  Doug then went to Trade #2 and discussed propellant choices.  Note his Table showing the specifics of his Choice of Fuels assuming 53 tons at LEO and a 15% dry mass.  He received several listener questions, including questions about where to on the Moon.  See Trade 8 Initial Landing Sites for his choices and reasoning.  We skipped to Trade 12 Power in Shadows.  He discussed power options in some detail and went through the four options listed in this trade.  Mary Beth sent in some questions asking Doug about his propulsion discussion and Marshall called in with a series of questions about ice and the regolith.  Doug then took us to Trade 17 Repairs.

In our second segment, Doug started with Trade 17 repairs, focusing on redundancy, spare parts, & surface equipment easy designs.  Later in the segment, Dr. Plata was asked about lunar dust and maintenance/problems for the equipment.  A listener emailed him about market possibilities, our guest fielded other listener email questions and then Doug addressed Trade 9 Landed Configurations including belly landings and tail landings. Trade 14 Surface Equipment was discussed, then John called in to talk about a needed detailed lunar surface survey.  I asked our guest for his detailed cost projections for his mission followed by his next step in promoting his architecture.  He talked about having called his Congressman, Representative Mark Takano.

Please post comments/questions/feedback on TSS blog per above.  You can also email Dr. Plata at his above email address, plus its on his trade document which is on TSS blog.

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.

    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.
