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.

 

Please post your comments/questions on TSS blog above.  You can reach Ben through the Planet Labs website or The Space Show.

We welcomed Rex Ridenoure back to the show to discuss Ecliptic Enterprise, LightSail, the NewSpace Conference & more. During the first segment of our 1 hour 33 minute discussion. I started our discussion by asking Rex how Ecliptic got the LightSail contract from The Planetary Society. Rex relayed the story to us of their involvement with LightSail & I am sure you will find it interesting. This discussion led Rex to update us on Ecliptic activities with their size reduction program for their avionics and their work on cubesat projects. Rex talked about their customer and project base and why they don’t have foreign launcher contracts or relationships. ITAR!! He talked about their having been denied ITAR clearance in the past so they don’t even bother obtaining it anymore. Rex talked about some of their camera space projects including LCross, transmitting data back via the DSN and the limitations because their cameras could work all the way to Pluto and beyond but the data transmission rate and capacity to do that for video is not available. We then returned to the LightSail project which Rex described in some detail during the balance of our segment. Rex also has suggested we read the blog articles on LightSail via Jason Davis on The Planetary Society website. www.planetary.org/about/staff/jason-davis.html and look for his posts on LightSail. By the way, it is an excellent blog and I recommend you add it to your regular reading list.

 

In the second segment, Rex provided us with an overview of the SFF NewSpace Conference and I totally agreed with what he said having also attended it. In my opinion, it was the very best of all the SFF-NewSpace conferences I’ve attended since the late 90’s. As part of his summary of the conference, I asked his opinion on the Dr. Linda billings Scientific American article that attacked SFF, NewSpace, space settlement, etc. Here is the article in case you missed it: www.scientificamerican.com/article/the-inexcusable-jingoism-of-american-spaceflight-rhetoric. Let us know on TSS blog what you think of Dr. Billing’s article and what Rex had to say about it. Please be respectful and civil, no name calling, even if you strongly disagree with either Dr. Billings or Rex. Since our show ended, Shubber Ali, the original Space Cynic, posted a reply to Dr. Billings on the Space Cynics website. Check it out as I will add all of this to the Open Lines discussion for Sunday, August 2: https://spacecynic.wordpress.com/2015/07/27/the-inexcusability-of-poor-reading-comprehension. As the show neared the conclusion, Rex summarized key points & highlights of discussion.

We welcomed Brent Sherwood back to the show to discuss NASA planetary science missions and in particular the Discovery class missions.  During our nearly two hour discussion without a break, Brent started out by telling us how NASA selects Discovery class missions.  He talked about the two kinds of science but focused on the Discovery missions which have a $500 million budget not including launch or operating costs.  He said it was open season on the solar system other than the sun or Earth as they were covered by other NASA programs.  In speaking about the history of Discovery missions, he named a few that we are all familiar with such as Kepler, Grail, Deep Impact, Stardust, the Phoenix Mission, Dawn and the upcoming Insight Mission to Mars.  Brent then explained the proposed missions under the auspices of his team.  These proposed missions include VERITAS, BASiX, CORE, Pandora, Proteus, Psyche, Kuiper, and ELF.  Brent explained each proposed mission to us, talked about the P.I. for each mission, and the science to be gained from the mission.  Listeners had many questions for him including how the principal investigator (PI) was selected.  Brent explained the process, where the PIs come from, how a mission is proposed, is it coming from a university or academic setting, has it been proposed before, or is it coming from JPL or another NASA center or the Applied Physics Lab (APL).  Brent was clear that Discovery missions, given their limited resources, were not about developing and proving out new technology so in answer to my question about the TRL of completing these missions, he said they were all coming in with very high TRLs though the missions sound very futuristic, even bordering on science fiction.  As for timelines, Discovery missions approved now would fly in 2021 so they have about a six year time frame to be developed and flown.  In response to questions, our guest addressed this six year time line in some detail.  All of these missions sounded very exciting but as Brent said, it is a very competitive process and only one or two if any of them may be selected as other teams are proposing their Discovery projects as well and they are equally exciting.  Later in the segment, Brent was asked about the choice of launch vehicle for each project.  This was a very interesting discussion, don’t miss it as our guest explained in detail the role of the PI regarding the launch vehicle and how NASA actually selects a rocket for the mission.  In response to BJohn’s question about launch costs, they certainly factor into the mission planning. Doug asked a question about the Photos-Deimos mission and if the mission could identify a favorable small crater which could later be the site for a covered habitat and if it could identify frozen volatiles in the polar craters of those moons if they exist.  Brent said it might have such capabilities but that these missions only do the work specific to their actual project.  He had more to say on this so don’t miss all his comments.  BJohn asked why not a Uranus mission.  Brent said Uranus was too far out and too costly for a Discovery class project.  Near the end of the segment, BJohn also asked about the importance of miniaturization now and for the future with NASA and these missions.  Brent said it was very important and then updated us on all the cubesat opportunities and uses being integrated into NASA missions.  He spoke about the significance of cubesats for several minutes so don’t miss what he had to say about them.  Doug asked a question about realizing economic value from these missions or at least what was the rationalization behind these purely science missions.  Brent provided an excellent answer to Doug’s questions so don’t miss it.  We ended the show after Brent’s response.  See what you think of it and post your comments on TSS blog.  Doug sent in a final note saying “I agree with his answer re: the value of science.  I believe that it is worth a certain amount of our money to increase our knowledge for its own value.”

We welcomed Dr. Richard Binzel to the show to discuss asteroids, the NASA ARM, and completing the NEO survey.  During the program, Dr. Binzel referenced two items. The first, his article in Nature is at http://www.nature.com/news/human-spaceflight-find-asteroids-to-get-to-mars-1.16216.  The National Academies study he mentioned is at http://www.nap.edu/openbook.php?record_id=12842.  During the first segment of our 90 minute program, Dr. Binzel introduced us to the asteroid topic, the asteroid belt, 1 km size asteroids and he responded to my questions about Asteroid UR 116.  Our guest then addressed the NASA ARM and explained why he is not supportive of it.  He referenced his above article in Nature on the subject.  You can get this article at the above URL.  He talked about visiting asteroids in their natural orbit rather than bringing a small one back to orbit the Moon.  He had much to say that was positive about visiting an asteroid, explaining as well why such a visit is on the path to HSF to Mars.  He then explained his program for completing the NEO survey which is to find and catalog specific NEOs.  Listeners asked him many questions including if radar was a good tool for finding asteroids.  He said no because it uses a very narrow beam.  He also said that were the NEO survey completed, most of the most accessible destinations for HSF and science missions would be cataloged and would open up space.  He goes into detail on this near the end of our show.  We talked about international NEO survey and planetary defense issues.  While the U.S. remains the leader, ESA is doing more and more.  He also said that rather than spending just $20 million on asteroid detection, we should be spending $200 million annually until the survey is completed.  Joe in Houston sent in a series of questions starting in this segment and ending when the show ended.  His questions, all of which were read on air, centered around ways to bring an asteroid into orbit around the Moon.  Listen to what our guest had to say about his multiple suggestions/questions.  Professor Binzel clearly likes and welcomes fresh ideas & also insists on running the numbers and doing the trade analysis.  John called from Ft. Worth asking about the size of an asteroid that should be getting our attention.  Time lines were brought up as we need time for the best way to deflect an asteroid on an Earth collision trajectory.  Near the end of the segment, our guest talked about a NASA Grand Challenge Mission around asteroid detection and intervention methods starting first with the survey, the concepts on how best to deflect an asteroid and then about 30 years out, a contest on an ISRU test for resource extraction on an asteroid.

 

In the second segment, Doug sent in multiple questions, then after I asked our guest a few of them, he called in to talk about some of the other questions on his list.  Doug asked Dr. Binzel good questions so listen carefully to their discussion.  One thing of note was that the size of an asteroid presenting the greatest risk to Earth is 140 meters.  Joe continued emailing evolutions of his initial three questions from the first segment.  Asteroid ISRU was again discussed in this segment, so was the likelihood of a comet impact on Earth, & a privately funded mission to complete the NEO survey was also discussed. As the program was ending, Dr. Binzel spoke to the issue of the NEO survey being a game changer and opening the gateway to our future.  This is important so do listen to his comments on this issue.

We welcomed back Dennis Wingo for this 93 minute discussion. PLEASE NOTE THAT WE ARE NOW CONDUCTING OUR ANNUAL FUND RAISING DRIVE.  WE NEED YOUR SUPPORT FOR THE SPACE SHOW AND ITS PROGRAMMING EFFORT.  During our first segment, Dennis talked about his recent blog article at http://denniswingo.wordpress.com, To ARM or Not To ARM: Is That Really Our Question.  I urge you to download and read this article as Dennis refers to it many times over during our discussion.  He started out with an analysis of what was thought to be the NASA ARM mission as compared to what it has become today.  As you will hear, he was supportive of the initial mission, not the current evolved mission.  He explained why the shift in his position which was based on making the ARM mission a minimalist type mission.  He explained the differences in detail.  Budget reasons were cited as a primary reason for the mission being downgraded.  Dennis offered us an historical analysis & perspective of the NASA budget.  SLS, Falcon Heavy, & lots of space policy made it to this segment.  Dennis talked about solar electric propulsion for ARM, then he was asked about the likelihood of the next president initiating an RTM program.  Doug emailed about a COTS like program with ULA & Masten for a lunar lander.  Dennis had much to say about a lunar lander dating back to the Gemini era up to new, lower cost ideas coming from the commercial space industry.

In the second segment, Dennis continued talking about the upcoming new Congress and what might emerge as a different type program with a different budget though he thought we were more likely to entertain the status quo.  Several listeners wanted to know if it would boil down to the Moon vs. ARM or the Moon vs. Mars.  Don’t miss his response to these questions.  Our guest suggested we all watch the “Wanderers” video which you can see at http://vimeo.com/108650530.  Dennis mentioned that we did not need a government program as such for space but he did speak in favor of public/private partnerships.  We spoke much about the need for space and lunar infrastructure.  Sally asked him to explain the difference with the economic development of the solar system and space settlement.  He said space settlement was very much a part of a space economic development effort.  In response to another set of listener questions, Dennis talked about the 90-10 rule when has about robots in space as compared to astronauts.  Doug called to talk about investment capital for commercial space plus other issues.  I then asked Dennis if Lunar Cots or industrialization was included in solar system economic development and if so, at what stage?  Kirk emailed in a question challenging the role played by offering prizes.  Don’t miss what Dennis had to say in response to Kirk’s email.  Before we ended the program, Dennis mentioned his latest blog article about Apollo betrayed by the very people who made the Apollo mission happen.  You can read this article at http://denniswingo.wordpress.com.

Please post your comments/questions on TSS blog above.  You can reach Dennis through his blog and articles or through me.

We welcomed Amnon Govrin to the show to discuss his thoughtful op-ed, “Is Microsoft the NASA of Software Companies.”  You can read this op-ed at http://www.spacepirations.com/2014/10/is-microsoft-nasa-of-software-companies.html.  During the first segment of our 100 minute discussion, Amnon shared his background with us and what led him to write this article.  He listed attributes of both organizations that made them similar, plus he provided his own background as a space enthusiast as well as working in the software industry and in recent years for Microsoft.  To establish the groundwork for his article, he talked to the amazing things both organizations have done as well as the innovations they have brought to not just the industry but to humanity.  He was asked about differences with one being a private company and the other a government agency plus he addressed politics which he said were plentiful for both organizations though different.  He looked at historic big projects for both organizations & the innovation of such projects.  He suggested common traits including research and technology.  Amnon talked NewSpace, also he went back to the early days of our space program with rockets and hardware, then he did the same with some of the Microsoft early projects and products.  Another topic in this segment dealt with layoffs for both organizations, consolidations, and positioning their respective organizations for the future.  He said the verdict was out on the success in doing this for both organizations.  Our guest talked about and  identified what he referred to as Black Sheep, a section of his op-ed.  Black Sheep referred to products and projects that don’t make it for one reason or another.  He said both NASA and Microsoft had a history of many Black Sheep projects and products and he identified a few including Vista and Constellation.  Michael Listner called to talk about the denaturalized approach of both organizations.  Amnon and Michael has much to say about decentralization.  About this time, we started getting breaking news information regarding the Virgin SpaceShip2 accident. We continued to report breaking news on this story during the rest of our program.

In the second segment, in addition to the breaking news reports, we talked about both organizations becoming stale meaning irrelevant, heavy, and even wasteful.  Again, our guest cited many examples for both organizations.  More interruptions took place over the Virgin accident story and news, then we moved to the conclusion section of the last segment.  He talked about the difficulty for both organizations going into the future and what may impact the future of both Microsoft and NASA.  For NASA, he mentioned NewSpace.  Then we talked competition and for NASA, he mentioned the private sector launch industry as this competition may force changes in the way NASA does thing.  He questioned if innovation was in decline.  In the final minutes of the program, I asked our guest for his 5 year view for both Microsoft and NASA.  We also talked Astronauts for Hire as our guest was a co-founder of the organization.

Please post your comments/questions on TSS blog.  You can reach our guest through me or his own blog above.

We welcomed Greg Cecil back to the program for this 1 hour 37 minute discussion.  During our first segment, Greg summarized his space shuttle experience when working on the thermal protection system at KSC, talked about keeping in touch with former shuttle employees and letting us know that in his opinion, shuttle was retired too early.  After the shuttle program was closed down, Greg began consulting and teaching science to middle school students.  He talked about the difference in a public inner city school as compared to teaching in a private school.  His observations are important, especially about parent involvement  & support in the student’s education.  Greg devised space related projects for the students & created scientific experiments to fly with the J.P. Aerospace high altitude balloon flights.  Greg described some of the experiments and the benefits in working with John Powell of J.P. Aerospace.  We talked about the impact of the flights and making the payloads.  I asked if the impact will remain with them as they go through school, possibly in selecting a space or science education and career.  Greg also attended the recent Explore Mars Humans2Mars Conference and here he offered us many valuable observations.  Listen to what he had to say about NASA Administrator Charlie Bolden’s talk, then later the talk given by NewSpace advocate and co-founder of the Space Frontier Foundation, Rick Tumlinson.  The differences between the two talks and approaches led to Greg’s conversion to being a NewSpace proponent.  Greg talked about SpaceX and suggested it was risky for any one company to be the face of NewSpace, either intentionally or by chance.

In the second segment, Greg talked about the movie, “I want To Be An Astronaut.”  Doug emailed in a comment based on our first segment discussion given Greg’s comment about NASA budgets being tight & being a show stopper for grandiose HSF missions such as those to Mars & as reported in the NRC Pathways HSF study.  Greg responded to Doug, then I let got with one of my infamous rants directed not just at Doug but we space enthusiasts in general for having lousy communication skills.  In this instance, my rant was about Doug focusing on technology and never ever making the case for the WHY or the need to do what he suggested in his question.  Greg then spoke to the importance of knowing your customer, congressman, market, and effectively communicating the WHY & the NEED.  Later, after the rant and aftermath of the volcanic eruption, Greg spoke to how best to approach members of congress and state legislatures.  We then talked about the RD-180 engine, SLS, & HSF spaceships.  As our discussion was ending, Greg pointed out the risks associated with putting all our HSF eggs in one basket and one company.  He closed by saying never give up plus he provided his email address at the end of the show.

Please post your comments/questions on TSS blog.  You can reach Greg through me or the address he gave out on air as the show was ending.

We welcomed James Pura and Aaron Oesterle to the program to discuss The Space Frontier Foundation’s Space Settlement Enabling Test (see http://spacefrontier.org/settlement-enabling-test).  During the first segment of our 90 minute program, James and Arron went over the history of how the Space Settlement Enabling Test got its start within the SFF.  We also learned that it is in response to public space programs, not private programs though parts of the test would be applicable to private ventures but applying it that way is not a purpose of the Foundation.  The SFF Board votes on the projects being applied to the test with the results being published on the SFF website (http://spacefrontier.org).  We learned that the test consists of 21 questions in seven categories with each question having a voting range of 1-5.  There is a score for the project being subjected to the test but there is no pass or fail.  For example, the Foundation applied the test to the now defunct Constellation program and its score was 36.5%.  Our guests explained in detail how the test worked and during this segment and part of the second segment, they went through the questions in each of the seven categories.  Listeners had many questions for them including how they planned on measuring the effectiveness of the test and the outcome.  Our guests talked about both the inside and outside means of using the test and getting the results out to the market, policy makers, etc.  One listener asked James & Aaron if the test was jumping the gun since space settlement is far off into the future.  Don’t miss the reply to this question offered by both our guests.  Doug called to talk about applying his Cis Lunar 1 project to the Space Settlement Enabling Test.  Prior to the end of the segment, our guests talked about the importance of insuring sustainability for space settlement and how that was reflected in the test.

In the second segment, we finished going through the balance of the test and then we opened up the discussion for questions.  In discussing the final categories, our guests brought up the issue and importance of space property rights, competition, and the need for a tax payer ROI on public space ventures.  We talked about what may contribute to a public sector ROI.  In the question segment, nuclear propulsion was brought up, our guests were asked if they had applied SLS to the test.  Each of our guests offer us important closing comments and take aways from our discussion.

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 https://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.
