We welcomed back Emily Lakdawalla for a far ranging planetary science and mission discussion.  During the first segment of our 90 minute program, Emily was asked questions about the Planetary Society’s solar sail mission, LightSail.  Look forward to a special Space Show program about this project in the near future.  I asked her about her Cassini Icy Moons article on her Planetary Society blog which can be found at http://www.planetary.org/blogs/emily-lakdawalla.  We talked about the photo mosaics and Emily told us about the software and how any of could easily do similar mosaics.  As you will hear, we talked about icy moons throughout our program.  The Dawn mission with its approach to Ceres was an important discussion topic as was New Horizons on the way to Pluto.  As all of you have heard before, this is the year of the Dwarf Planet!  Dan called with questions about Mars 2020 and the sample return mission.  We touched on human spaceflight and addressed the NASA planetary budget.  Roy called to ask about the Thursday press conference about Ganymede, then before the break we got a question about the Rosetta mission and the Ceres bright spot.

In the second segment, Emily had more to say about New Horizons, how photos and data would be sent back to Earth, and the upcoming cliff hanging moments with New Horizons and why they are considered cliff hanging.  Don’t miss our New Horizons discussion.  Callers and questions came in about Europa, the overall cost of planetary missions for the American taxpayer, the Dawn orbit around Ceres and limitations due to hydrazine.  One listener even asked if there would be public events around New Horizons arriving at Pluto.  Near the end of the segment, Doug sent in several emails asking about Uranus and Neptune and here Emily had much to say in support of such missions.  I asked our guest about her preference between inner and outer planets.  We also talked about returning to the Moon.  Near the end of the program, Carl wanted to know what was going to happen with planetary science after New Horizons.  A series of lunar questions came in with one asking about a lunar sample return.  I asked Emily if a lunar sample return was needed given the quantity of Moon Rocks that we have from the Apollo era.  Don’t miss her most interesting reply with a focus on possible contamination from the lunar Imbrium event.  As our program was ending, Barry wanted to know why we were using radio communications from the outer planets rather than light.

We welcomed Dr. Arlin Crotts back to the show to discuss his new book, “The New Moon: Water, Exploration, and Future Habitation” plus lunar related science and development issues & concerns. For more information, visit Dr. Crotts website, http://user.astro.columbia.edu/~arlin/research.html.  In the first segment of our 93 minute program, I asked Dr. Crotts to summarize lunar science and development progress since his last appearance on TSS, Oct. 27, 2009 through today.  Dr. Crotts had much say in this summary, especially with lunar water, hydroxyls, minerals, LCROSS, volatiles, and more.  Don’t miss this summary. Listeners asked many questions about INSITU Resource Utilization on the Moon, polar ice, water ice, volatiles, fuel possibilities, and more.  I asked if he had detected an increase in the public’s awareness of the Moon and many of these issues plus I wanted his thoughts on the private sector commercial opportunities and plans opening up for the Moon.  The balance of this segment featured calls and listeners emails asking about the lunar poles, volatiles, craters & the Resolve Mission.

In the second segment, Dr. Crotts was asked about the Lunar Mission One Kickstarter project and their wanting to drill 100m into the Moon.  Dr. Crotts did not comment on the project but did talk about why we needed more and deeper lunar drilling exploration.  Our guest also talked about his book in detail in this segment, saying it was very detailed, well documented and supported, and that readers would learn things about the Moon not previously known or written about given his access to original lunar exploration and Apollo documents.  Other topics in this segment addressed humans to Mars or the moons of Mars, the timing of human lunar settlement which he supported but not until we know much more about the Moon to do it safely and correctly.  We talked about this approach in some detail.  Space settlement was discussed and he said it would happen sooner or later but that we needed more lunar science first before we settled the Moon.  Near the end of the segment, Dr. Crotts was asked about NASA’s ARM project.  Space mining came up and then just before the program ended, Eric inquired about Transit Lunar Phenomena (see http://user.astro.columbia.edu/~arlin/TLP).  Tim was our last caller asking about the use of RTGs.  Dr. Crotts talked about reactors on the Moon and mentioned the smaller Toshiba 4G reactor.

Guest:  Michael Paul.  Topics:  The Penn State Google Lunar X Prize entry, the Lunar Lion.  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.

We welcomed Michael Paul to the program, the leader of the Penn State Google Lunar X Prize team, the Lunar Lion.  For more information, visit their team website, http://lunarlion.psu.edu.  Michael brings to the table his experience with NASA and the Applied Physics Lab at John Hopkins as he was the spacecraft systems engineer for the NASA Messenger mission.  During the first segment of our 95 minute program, Michael talked about the Lunar Lion project.  We discussed launch contracts and vehicles, secondary payloads, landing sites, hoppers as opposed to rovers, and what happens to the hardware at the end of the mission.  We talked about the Penn State students working on the project and listeners and I asked questions about his experiences on Messenger being applied to a GLXP project.  The listeners seemed to think this was a step or two down but listen to how Michael explained lessons learned and applications to the Lunar Lion project.  We also talked about funding for their project and that if they win, the money goes to Penn State to endow further space related research and students. We also had a treat in the first segment in that Michael’s 10 year old son was with him. We invited him to the program and it appears we may have a future space guru in the making!

In the second segment, we talked about space education and general audience space enthusiasm and awareness given Michael’s public talks.  He had some interesting comments and experiences to share with us.  We also talked about potential regulations adversely impacting their mission, sample returns, lunar activities and such.  Charles called to talk about up and downstream communications and the use of lasers.  Spacecraft quality control was another issue along with the development of commercial tools for a much broader application than the Penn State GLXP entry.  He also mentioned efficiency in spacecraft design and management but used the term, “a frugal approach.” He explained the difference between frugal and efficiency in terms of spacecraft design & management.  As our program ended, we talked about thermal protection, radiation hardening, film and space subjects and topics.  Our final topic was oversight and 3rd party eyes on their project for review & quality control.

We welcomed Yonatan Winetraub as our guest to discuss SpaceIL, Israel’s Google Lunar X-Prize entry.  Mr. Winetraub founded SpaceIL through an interesting set of experiences and conversations at a local Israeli establishment.  He tells us this interesting story as we begin our one hour discussion. At age 26, Yonatan proves that much can be done with passion, commitment, education, volunteers, and local industry support.  During our discussion, Yonatan told us about the SpaceIL plans, the lunar hopper that they will land on the Moon, and their process in procuring a secondary launch contract for the launch capable of putting their lander on a trajectory to the Moon and landing in time to win the Google Lunar X-Prize contest.  One issue we discussed in detail was the fact that their secondary payload would have propulsion on board making it challenging to be approved as a secondary payload by the primary payload on the launcher.  In fact, Charles both emailed and called at the end of the program to raise the propellant issue for secondary payloads.  SpaceIL as a nonprofit, is also engaged in STEM and education outreach in Israel and this too was a significant part of our discussion.  Yonatan got questions about commercial space and space attitudes in Israel and the treatment of their venture by the Israeli general public and press, both in Israel and internationally.  The Google Lunar X-Prize competition was discussed as well as their funding and plans for after the contest ends. Given that SpaceIL is consulting with American companies, we talked about our ITAR laws as well as the Israeli ITAR laws and regulations.  The SpaceIL website is www.spaceil.com and I urge you to follow along on the site while listening to this discussion.

If you have comments/questions for Yonatan Winetraub, please post them on the blog and I will call them to his attention.  You can also email him through drspace@thespaceshow.com.  We will certainly be talking with Yonatan again as they progress in the competition.
