Welcome to our first May 2016 Open Lines program.  During the first segment of our very long 2 hour 26 minute program, I suggested 13 topics for discussion.  While we did manage to discuss most of them, the most popular included remembering Charles Pooley and talking about the EM drive.  Many listeners called in during both segments to remember Charles Pooley.  Also in the first segment, the EM drive came up for discussion with John in Ft. Worth.  He had much to say about the potential of the EM drive, plus he commented on why many traditional scientists say nothing is there, that any results are only on the margin.  I cited a recent article at www.nasaspaceflight.com/2015/04/evaluating-nasas-futuristic-em-drive.

 

In the second segment, we started off with Steve Nixon talking about Charles but it soon evolved to a discussion about space solar power and the upcoming ISDC conference.  In touting SSP, Steve referenced the work by Keith Henson and others, the SunSat Competition, and more.  I was extremely skeptical of his SSP claims which depended on Skylon working and significantly lowering the cost of space access. That claim made me even more skeptical.  I told him Keith was welcome back on the show to discuss his latest SSP analysis, assumptions, and claims so we will see if Keith wants to return after ISDC which is later this month in Toronto.  I recall earlier comments & analysis by Keith which were certainly in the skeptical range from my perspective.  I do hope he returns as we can have a good discussion with lots of listener participation.  Based on listener emails and some phone comments, I was not the only one skeptical about the latest SSP claims.  BJohn emailed us to say that Pooley’s idead were coming into their time, plus he commented on EM drive.  Dr. Dwayne Day called in and somehow we got to talking about high price art auctions and the Picasso that just sold at Christies for $179 million +.  I also referenced the Christies auction last year of James Bond movie items including the original Moonraker Space Shuttle model which sold for $89,000+.  Dwayne then addressed his reason for calling which was a recent Jeff Foust article reporting on the status of the NTSB investigation and report regarding both the Virgin Galactic and Orbital Antares accidents.  Dwayne’s comments on the investigation were interesting so make sure you hear them.  We talked more on the EM drive, then Tim called to refute SSP as well as terrestrial solar power. He also said the EM drive could be used as a doomsday weapon!  Dr. Doug called and said kind things about Charles, then he wanted to talk about home grown space experiments.  He briefly mentioned one he did regarding eating dried foods.  He will have more to say about this on the next Open Lines show at the end of this month.

We welcomed Dr. Doug Plata back to the show to discuss his Return to the Moon (RTM) segment within the Space Access Society (SAS) meeting last week in Phoenix, plus space policy and other topical issues.  Due to a server glitch and phone line issues in connecting with Doug, this 100 minute show does not have a break as we took our breaks to reconnect to the server and Doug.  As we started out our discussion, Doug gave a shout out to Space Access and to the founder of it, Henry Vanderbilt.  Doug then turned his attention to his Return to the Moon conference within the Space Access Society conference. Doug also provided us with his specific definition for Lunar Cots.   He mentioned the key speakers including Jeff Greason, Jim Muncy, Erik Seedhouse, and Dave Masten.  He summarized each of their presentations, plus he mentioned the SAS lead in speaker to his segment, Dennis Stone of NASA JSC, and the speaker after the RTM segment, Bruce Pittman.  Doug said both speakers were so on topic that in reality they could have easily been part of the RTM segment.  Doug discussed lunar lander options, powering rovers on the lunar surface, especially after taking a call from Jon in New Jersey.  He went into some detail on the presentations within the RTM segment.  BJohn in Sweden asked several quality questions via email so pay attention to them when I read them on air.  Space policy and politics came u as Doug was concerned that a NASA RTM effort might be part of a larger international effort, not a public private partnership effort and it would result in footprints on the Moon all over again without sustainability.  Near the end of the program, he discussed this with Dr. Lurio who called in to raise issues around Doug’s comments & concern.  Doug also reported on the rest of SAS including the Virgin Galactic talk/update.  Again, I apologize for the streaming and phone line issues early in this show.

We welcomed Hannah Kerner to the program to discuss the upcoming NewSpace 2015 Conference in Silicon Valley at the Doubletree Inn, San Jose, CA, from July 16-18, 2015. For more information, the conference agenda, registration and contact information, visit https://newspace.spacefrontier.org. During our one hour discussion, we talked about Hannah deciding to work this summer for Planet Labs rather than Google and why. We then talked about the first day keynotes including Pete Worden who just retired as the director of NASA Ames and NASA Administrator Charles Boden who will be at the conference for his talk. We then took a look at some of the panel discussions planned for the conference as this year’s NewSpace event consists of all panel discussions. While the conference agenda is filling up, Hannah did say there might still be room for panel speakers/participants so if one or two of the panels matches your expertise or area of interest and you would like to participate, send her or Curtis an email. You will find their email addresses on the conference contact page which is https://newspace.spacefrontier.org/contact. We also talked conference logistics, registration, hotel availability, and airport transportation from San Francisco airports to the conference hotel in San Jose. A listener asked about family and tourist activities in and around San Jose in case he decided to bring his spouse and children with him. Thus, we talked tourist attractions for a few minutes. Hannah also went over the lunch, networking, evening and gala details and registration as they are separate from the conference registration. Near the end of our discussion, I asked Hannah for her favorite panels. She told us her two favorites were the alternative launch panel on the first day and the Saturday panel, “The Users and Futures of Low Earth Orbit.” A listener asked about there being a business plan competition this year. Hannah said details would be announced soon and that it was being worked into the existing conference agenda. Listeners asked about the SFF annual Advocates meeting and Hannah gave us a teaser about several special announcements to be made at the conference including one that pertains to NewSpace 2016.

We welcomed UCSD freshman aerospace engineering student Darren Charrier to the show to discuss his UCSD SEDS projects including building a 3D rocket motor and a 6U cubesat communications center for their lunar lander. Make sure you see the video of his TED talk, www.youtube.com/watch?v=e9umkenQDoY.  In the first segment of our 1 hour 27 minute program, Darren started off explaining his interest in space, the Moon, and mining lunar HE3 to solve energy problems around the world.  He also explained why he decided to attend UCSD over other aerospace engineering schools.  We then got into the specifics of the three SEDs projects being worked on at UCSD by Darren’s team, the 3D printed rocket motor which was an existing program before Darren came to UCSD, plus the lunar lander and the 6U cubesat lunar orbiting communications satellite needed for their lunar lander.  The group intends to ride share to the Moon but it was too early to announce anything specific about that.  The timeline is by Darren’s graduation from UCSD in approximately four years.  We also learned that the 3D rocket motor will enter the competition later this summer in Green River, UT (we usually do a Space Show program on this event once the winners are known), plus their 6U cubesat bird will be entered in a NASA competition.  Darren was asked about his team and the UCSD administrative support for their projects, plus he was asked for specifics regarding the 3D printed rocket motor including its performance specs.  Darren talked about fuels that will likely be used by the 3D motor plus they may use a version of it to propel the lunar lander which they want to make a soft landing on the lunar surface.  Abut the lander, I inquired what it would do on the surface.  He said they would be pleased if it accomplished the soft landing plus survived a lunar day.  They want it to call home and take photos.  Our guest received several questions about the UCSD SEDS chapter as well as SEDS on a national level.  One listener asked him if they had ITAR issues, especially with foreign students.  Don’t miss his response to this question.  Bill called from Chicago to talk about Darren given he knows hm.  We learned much about this young, inspired student and future industry leader.

In the second segment, I asked Darren if he wanted to carry out his lunar plans as a private company or with government. He wants to be a private company with the government as a customer.  We also talked about Darren’s larger set of plans for the Moon including his starting a lunar landing business, servicing lunar tourism, additional mining over and above HE3 and more.   When asked about going to Mars, he said the path to Mars was through the Moon.  He supported asteroid mining but thinks it is far from being ready now and the path again goes through the Moon.  Doug called to ask more questions about the 3D motor and mining HE3 on the Moon. This latter subject was a major part of the Part 2 discussion with listeners as there were many questions about mining HE3, fusion development, HE3 on Earth, and even seriously using thorium rather than trying to develop lunar HE3 resources.  John from Ft. Worth called in on this and suggested using lunar HE3 for advanced spacecraft propulsion from the Moon rather than bringing it back to Earth.  There was plenty of listener interest in the fusion-HE3 discussion.  Returning to asteroid mining, Darren said one of his goals was to mine asteroids but that it was still a very long ways off.  He said “mine the moon first!”.  As the show was ending, we talked some more about thorium here on Earth, appropriate conferences for Darren to attend and he gave a shout out to his team members.

We welcomed Bruce Pittman back to the show to discuss the upcoming ISDC 2015 Conference to be held in Toronto, Canada from May 20-24, 2015.  During our one hour program, Bruce talked about ISDC events in general, then the Toronto location for this year’s conference and the conference location, the Hyatt Regency Toronto.  ISDC is a multi-track conference with workshops and an excellent exhibit hall.  For more information, registration, hotel bookings, visit the ISDC 2015 website, http://isdc2015.nss.org/wordpress.  From time to time during our discussion, Bruce mentioned a separate event needing separate registration, The Space Innovation Business Summit (http://isdc2015.nss.org/wordpress/the-space-innovation-business-summit).  Bruce also went over the list of the keynote speakers, all of which are listed on the ISDC 2015 website.  In fact, I strongly suggest you open the website and follow along with us during our discussion about the event.  Bruce also said there would be upwards of 300 students present from around the world as a result of the Space Settlement Contest.  Bruce highlighted both India and Romania for their student participation in the contest and ISDC 2015.  Listeners asked many conference questions including networking, Q&A sessions, and inquiring if there was both a propulsion track topic and a human factors track topic.  Toward the end of our discussion we took a call from Doug regarding EML2, depots, fuel, Mars transportation, etc.  If you are planning to attend, remember you need a passport to enter Canada. Reserve early for the hotel, the conference and your transportation.  ISDC is a terrific event. If you attend, I want to hear from you about it on The Space Show.

SPECIAL ANNOUNCEMENT, MONDAY, MAY 4, 2015

In Memoriam

The Space Show lost a good friend and I lost a good personal friend this weekend as Charles Pooley passed away.  At this time I have no additional details.  All Space Show programs this week will be dedicated to the memory of Charles. On our Tuesday, May 12 Open Lines show, those of you who wish to email or call in and remember Charles, please do so.  We lost a really good guy this weekend, a space advocate and solid engineer thinking guy who was very special.  Charles Pooley will be missed and remembered for years and years to come.

Rest well my friend.  We will always remember you, miss you, and treasure your Space Show programs and moments,

Your friend,

David

We welcomed Damian Peach, well known amateur astronomer from the UK to the show.  Visit his website for more information and to see his work, www.damianpeach.com.  During the first segment of our 90 minute program, Damian talked about his early interest in space and the definition for an amateur astronomer. We learned most are self taught as was the case with Damian, that the field was not as math intensive as a professional astronomy career and that amateur astronomers significantly contribute to the field of astronomy and work well in harmony with professional astronomers.  During this segment, listeners had many questions for our guest including asking if he had sponsors, the cost of amateur equipment, his typical viewing schedule on the South Coast of the UK where he lives and his other location, Barbados.  In fact several questions came in about viewing conditions in Barbados and the effect of weather and humidity on his viewing in that location.  Damian likes to photograph Jupiter and Saturn and the bigger outer planets.  Don’t miss the why behind this.  As you will hear and you can see on his website, he has also done lots of excellent imaging of the Moon.  I asked him about his interest in going to Mars, human spaceflight, and more, all of which he said he was interested in.  Other first segment topics included wanting to know more about his techniques, amateur spectroscopy, and amateur peer review.  Regarding his interest in Jupiter, he talked at length about the always changing Jupiter weather that he liked to document in his Jupiter photography.

 

In the second segment, he talked about the upcoming JUNO Mission to Jupiter & the need for amateur astronomers to take images and submit them to the JUNO team.  Other topics in this session included cubesats, amateur astronomy groups in Europe, the U.S. and elsewhere, plus Pluto and New Horizons.  Listeners asked about amateur solar and deep space astronomy, cosmic rays, and more.  Science fiction came up as did the movie Interstellar.  Later, Ben sent in a note while looking at Damian’s Mars images on his website and asked about color enhancing and photo touchups.  Imaging Mercury and Venus came up in the discussion as did light pollution, viewing & searching for comets & NEOs.  Near the end of the program, we talked about Ceres and the Dawn Mission from the amateur perspective.  Near the end, I asked Damian his first choice mission were he the space mission guru.  I bet you will be surprised by what he said.  Dr. Dewar asked about making space access available with space based telescopes through nuclear propulsion given the cost of launch would be so much cheaper. Don’t miss Damian’s response.  Marshall called at the end to talk about technology advancement & more.

We welcomed back Brent Sherwood for updates to his human spaceflight analysis work previously presented on The Space Show.  During the first segment of our 1 hour 48 minute discussion, Brent started out with a brief discussion on scientific missions and the year 2015 being the Year of the Dwarf Planet.  He talked about the Dawn Mission and Ceres, New Horizons and Pluto, and the oceans on the outer planet moons.  Exoplanets and the habitable zone were also part of this discussion which included an assessment of just how our knowledge has changed regarding the compositing of the solar system.  To redirect the conversation to the purpose of today’s show, human spaceflight (HSF), I asked Brent when we would see HSF beyond LEO (BLEO). I asked about what seemed to be a new space advocacy push for space settlement. Brent then examined why HSF and referred us to his earlier work and the four reasons for HSF which were explore, exploit resources, to experience space, and settlement.  He said settlement was clearly part of the debate, talked about earlier workshops which would avoid the topic and then spoke to the recent Pioneering Space meeting held in Washington, DC where there was a consensus reach for space settlement.  He had good things to say about the meeting and the consensus resolution and talked about the broad space industry representation at the meeting as it was not just NewSpace.  Don’t miss what he had to say about it and space settlement.  Brent was also asked if our National Space Policy Act needed to be amended to reflect space settlement as the official goal of NASA.  Later, he was asked about the stepping stone or incremental approach to HSF development.  He supported this approach, spoke to the challenges for HSF such as life support and more.  As we were closing out the first segment, he offered us valuable insights on this topic so don’t miss what he had to say.

In the second segment, John from Florida called in to ask about grand space visions like an O’Neill orbital colony.  Brent proceeded to discuss grandiose visions in the context of how challenging they were plus their replacement cost.  Here, he used the replacement cost for Manhattan as an example of what he was talking about.  He cited a different type of example, the NASA Ames Space Settlement Contest that had nearly a thousand entries this year from 21 countries with the winner writing a 247 page grand space vision report.  Brent also spoke to the inspiration factor when talking about this contest.  A variety of listener emails were read on air for Brent to respond to, then I asked him if he thought Mars was the Holy Grail for HSF.  He said no so don’t miss why he said that.  He was asked about nuclear propulsion, then we talked about returning to the Moon , cislunar development, and then back to Martian settlement.  He was asked about going to the moons of Mars and he said there were two ways to settle Deimos.  Don’t miss his comments here either.  Near the end of the program, he said the physics of HSF were good but the problem was centered in being grounded in what he called program or budget math.  The budget math for HSF simply does not work, especially for a commercial venture.  He closed on the reality check of being grounded in budget math and the difficulty in going to Mars with humans.
