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 Emily Lakdawalla to the program to discuss space science missions, The Planetary Society, space & outer planet geology.  During the first segment of our 90 minute program, Emily went over her background and how she came to have an interest in space and in particular space science and geology.  Some of our topics included the tectonics of Venus, asteroid mining, her interest in the outer planets of the solar system, and science missions either ongoing or to be conducted in the future.  I mentioned a possible Europa mission which led to a Europa discussion and Emily talking about the ESA JUICE mission (JUpiter ICy moons Explorer).  We talked about being able to cut the travel time to the outer planets for science missions and our guest mentioned the possible use of SLS to do that.  Don’t miss this discussion.  Also in this segment, we talked about upcoming comet and asteroid mission, then we switched gears to discuss robotic challenges.  Here, Emily pointed out the time lag for communications to Mars and beyond makes telerobotic control difficult at best.  We talked about having a Mars orbiter to control surface robots.  Were we doing this, the robots could be simpler as they would not need as much autonomous capabilities as they need now based on Earth communications.  Emily told us about Planetary Society projects and programs, we talked about man in the street interviews regarding space & our guest shared her experiences with us when Shuttle Endeavour came to Los Angeles.  Near the end of this long segment, Kepler came up, questions came up about Earth geology being similar to the geology of the planets, the lack of fossil fuels on other planets, then Doug called with a question about coalition building & the NASA science budget.  As the segment ended, we asked Emily about robotic exploration as compared to having a human geologist on the surface of the planet. BJohn from Sweden sent us emails about Curiosity on Mars and Venus.

In our second segment, we talked about relevant time spans and how missions get prioritized.  Emily went over the Venus challenges.  She was asked if the Planetary Society would try another Phobos-Grunt mission and we talked about their project, the Mars Microphone to bring back to Earth the sounds from Mars.  Toward the end of the program, Emily was asked about the importance of lowering launch costs for science missions and the promotion of space advocacy.
