We welcomed Ben Haldeman of Planet Labs to the show.  During the first segment of our 87 minute show, Ben introduced us to Planet Labs, told us about the company history, goals, and Dove satellite imaging program wherein they want to image the entire Earth every day.  You can find out more about this at their website, www.planet.com.  Ben described the size and nature of their satellite fleet, how they can cover the entire planet once a day, their agnostic launch  policy, and their cubesat manufacturing process for their 10cm x10cm x by30cm finished product.  He explained the company’s iterative approach, the company employee growth, and their recent payload losses on the Antares and the Falcon 9.  We talked at length about the ISS process of getting the Dove satellites, launching them from the ISS, and the astronaut training needed to carry out the Planet Labs mission.  Also discussed was the orbital decay profile for their satellites at the end of their life, altitudes for their Dove satellites, and plans to use the preferred sun synchronous orbit given the ISS may have a limited remaining life expectancy.  Ground stations were described as was the satellite pointing process.  Listeners asked many email questions including the use of off the shelf GPS and  the range of optical spectrum/wavelengths for the cameras/sensors being able to detect images.  Listeners also wanted to know if Planet Labs had plans to make satellites via 3D printing and if any radiation hardening was being used with their onboard electronics.

 

In the shorter second segment, we talked about Planet Labs hiring and their internship program.  The company mostly hires engineers but about 25% of their hires are from different disciplines.  They also hire a person a day so if you are interested, be sure to check it out.  They are located in a truly exciting and creative part of San Francisco, known as SOMA (South of Market) and this is the area to be in if you like technology, want to be on the leading edge of the cutting edge, and be surrounded by peers that redefine the meaning of the word.  You can find out more about their hiring and intern program by checking their website.  Adrian asked another question about solar sails and CCD cameras.  I asked Ben the question Debra was asked by a Mom on the Friday show regarding her child studying engineering but preferring Apple Computer for example over a space company.  I asked Ben to respond to that Mom’s question.  Don’t miss what he had to say about it as our discussion involved Silicon Valley, being located in the San Francisco Bay Area which is a highly evolved tech market place, including the Bay Area universities, and more.  Ben ad some very interesting observations about this and was able to address what is happening in other parts of the country that are not as tech dominated as Northern California.  Before the show ended, Ben was asked about the future financial plans for the company, plans to work with Bigelow private space stations, and polar launches from Vandenberg.  Don’t miss his concluding comments as he told us what excited him about his work.  Remember, while he liked space, he did not come to Planet Labs from college as a space geek or advocate, thus his perspectives were most interesting and we thanked him for sharing this information with us.

Guest:  Wayne White.  Topics:  Space real property rights, salvage law and mining law 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. 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 welcomed back Wayne White, noted space attorney, for an excellent discussion on real space property rights, space salvage law & space mining law.  Given the amount of email and listener calls during the program, we went to  2.5 hours! Wayne started us out with about a 20 plus minute overview of space and related property rights today, the governing U.N. treaties, & the problems ambiguity causes in the financial and investment worlds. He also gave us good working definitions for both common law and natural law.  He spent some time discussing this in terms of establishing property rights in space.  This discussion included territorial property rights stemming from sovereignty as well.  I believe Wayne’s introduction to the subject was most useful in giving us the basic understanding of the issues so we could move forward with our discussion in the program to possible solutions and why some possible solutions would not work.  After Wayne finished his introduction, I offered some challenges to his assumptions and we fielded several listener emails and a call from Marshall.  My assumption challenges were based on a different outcome for private sector financial & economic growth & investment should governments continue with economic problems or face a much worse set of economic conditions than we see today.

In the second segment, we talked orbital debris and mitigation issues, the reality of satellite service and much more. Wayne also cited the Nimitz law suit against NASA for parking fees re asteroid 433EROS as evidence that the courts need a property right legal format to even hear such cases.  He also mentioned one of Rand Simberg’ s recent property rights ideas around the Space Settlement Prize Act.  Wayne went into details as to why in his legal opinion, this idea would not work.  We talked about the U.N. treaties, benefit sharing per the U.N. treaties as being part of the property rights issue, and the idea of establishing a legal Authority for issuing property rights.  Listen to why Wayne was not enthusiastic about any of these suggestions or alternative ideas.  Near the end, Bethany sent in the question I referred to in my earlier comments in that she suggested the resolution re space property rights rests with the companies that want to go to space for commercial purposes and need property rights for their businesses  That in fact, it was not our responsibility to do this as the responsibility belonged to those wanting to commercially operate and profit through space commerce.  We discussed Bethany’s question & Wayne agree with her. We talked about company lobbying & other things they could do to influence policy makers.  Our last call came in under the wire from Charles to suggest Antarctica as a model for space property rights.  Wayne explained why that was not a good model.  At the end, Wayne suggested some actions for space enthusiasts interested in this issue.

Guest:  Gil Moore.  Topics: New CubeSat program including POPACS, Rampart, PrintSat, 3D Printing and more.  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.  We welcomed Gil Moore back to the program to talk with us about his new CubeSat projects including Rampart, PrintSat and POPACS (Polar Orbiting Passive Atmospheric Calibration Spheres).  We also talked about 3D printing, the previous Starshine Project plus small satellite elliptical and circular orbital concerns, trajectories, and issues. Rather than writing this summary per the program’s two segments, I am doing it as one continuous summary for the nearly two hour discussion as our topics and themes did not change much.  Gil provided us with an excellent understanding of these programs which also offer terrific student opportunities for both high school and college students to get involved in satellite and space projects.  As you listen to the program, Gil provides names and email addresses for people to contact, including himself.  If you have questions, want to know how to participate in these projects, or just want more information about cubesats and the industry, do make use of the contacts.  Not only did Gil take us through complicated cubesat orbital dynamics, he stressed the need to give students the space and “the opportunity to do their own thing.”  If you want to research areas Gil talked about during our program use Google for the following key words and topics which are just a few of those mentioned in our discussion:  , Project Starshine, POPACS (Polar Orbiting Passive Atmospheric Calibration Spheres), 3D Printing, Rampart Cubesat project, Cubesats, PrintSat, Windform XT, elliptical orbits, circular orbits, N-Prize, See Sat, CelesTrak, Satellite Tool Kit, Dr. T. S. Kelso, polar orbits, secondary propulsion, and the NASA Get Away Special Program, a program referred to by Gil as the best student outreach program ever for Nasa but it was eventually cancelled.

If you have comments/questions regarding this program, please post them on The Space Show Blog.  Gil did provide his email address so feel free to contact him at GilMoore12@aol.com.  The abstract for the paper he referred to which he gave at SmallSat this year can be found at www.smallsat.org/technical-program/sessionx.pdf.

Guest:  Dr. Lewis Fraas.  Topic:  Mirrors in space for affordable solar electric power.  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. We welcomed Dr. Lewis Fraas to the program to discuss his MiraSolar Satellite Concept for mirrors in space for solar electric power.  I have posted two of his presentation papers and slides on The Space Show blog for your review.  You can find more about his concept by visiting his website, http://jxcrystals.com/lendrupal.  At his website, go to the lower right corner for links to MiraSolar.  As our discussion addressed common topics throughout our 90 minute program, I’m writing this summary without regard to program segments.  We started our discussion by asking Dr. Fraas to provide us with an overview of his mirrors in space concept.  This he did, drawing from time to time upon comparisons with space solar power concepts placing their satellites in GEO while the mirrors would be in LEO around 1,000 km.  Dr. Fraas made comparisons with SSP and mirrors in space throughout our 90 minute discussion.  We talked about optics and physics as well as the power generating size of the ground stations used in his concept, comparing those to nuclear power plants and other power generating facilities.  I believe you will find the power comparisons most interesting.  We spent a considerable time going over the launch and project economics as well as due diligence from a mostly economic perspective.  As you will hear, there are some blanks yet to be filled in but since this project is a decade or so out in the future, it is challenging to project values and costs that far into the future, let alone what launch vehicles we will have along with their flight, payload, and price characteristics.  Another important part of the discussion focused on ground stations.  Dr. Fraas zeroed them out of the economics when the ground station was built for or was being used for terrestrial solar as the mirrors in space project can make use of the same station.  In cases where the mirrors program needs its own ground station, those costs would be factored into the total project costs.  Listeners asked about environmental issues, an EIR and its challenges. Dr. Fraas made a point of being clear that this was an international project, not just focused on the U.S.  He also suggested that there was a possibility of limiting or restricting U.S. regulations down the road but that other countries might be more interested in mirrors in space, including China, Japan, and India. We had an interesting discussion about the U.S. and the space progress being made in other countries.  Tony asked a series of questions pertaining to using more not fewer mirrors for terrestrial solar farms.  He also wanted to know the launch price that made the project viable.  Dr. Fraas referred to NASA and other studies and cited two reference launch prices.  See what you think when you hear this discussion.  Another topic dealt with radiation at the orbit Dr. Fraas discussed. Here, we talked about the inner Van Allen belt and thanks to a listener, we got some info on debris issues at the desired orbit.  Don’t miss this discussion.  As we heard, it might be advantageous to shift the orbit to 1200 KM for debris mitigation purposes.  Another discussion topic addressed competition with always improving terrestrial forms of energy under development and in the process of coming on line.

You can email Dr. Fraas for more information at lfraas@jxcrystals.com.  Please post your comments/questions on The Space Show blog and I will be sure to call them to the attention of our guest.

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.
