John Batchelor and I welcomed Dr. Jeff Foust back to Hotel Mars. During our 12 minute Hotel Mars segment, we talked about significant space events and missions during 2014 including the recent methane discovery on Mars, Curiosity findings, Space X & Orbital Science 2014 events, the Rosetta mission, New Horizons to Pluto, and the Dawn mission. Virgin Galactic’s accident was reviewed as was the Antares rocket motor explosion and Orbital making an agreement to get new RD 181 Russian rocket motors for Antares. Also discussed was Venus Express and recently launched Hayabusa 2 mission. Jeff provided us with updates on all of these missions and companies.

We welcomed back Dr. Gil Levin to continue our discussion about Viking 1 and 2, the possibility of finding life on Mars, and the Viking Labeled Release Experiment.  In the first segment of our 1 hour 21 minute discussion, Dr. Levin explained why the name “Labeled Release Experiment” was used rather than his first choice, Gulliver.  Dr. Levin talked about liquid water on Mars with the findings that there is probably 2% liquid water in the surface area.  He compared that to the amounts of water found in in dry soils on Earth which supports microbial life.  He also talked about complex organics which he says has not yet been confirmed though he questions why certain Curiosity experiments which he believes have been done have yet to release their findings.  Rick was our first caller with questions about water, NASA policy, and green spots found on rock and what that might mean.  Gil also spoke about his presentation at the SPIE Conference recently held in San Diego and the panel he was part of with a NASA representative.

In the second segment, Gil took a question about the meaning of perchlorates on Mars, he addressed additional questions on liquid water and discussed the recent press releases from NASA and others that there was no methane on Mars and what this might mean for looking for life on the Red Planet.  Regarding methane, our guest had much to say and that the findings were not conclusive for all of Mars nor does there have to be methane for organics.  I asked him about the timelines involved in Viking 1 and 2 and you might be surprised to learn it was a 20 year process.  A listener asked about the odds of finding intelligent life on Mars and our guest said pretty slim.  He was also asked about searching for life elsewhere in the solar system and he said Mars was the best choice and listed the reasons why, including the economics of space exploration.  A listener asked if Curiosity & other missions were shut down due to the government budget crisis. Doug emailed us that Curiosity was still up and running.  Later, Doug called at the end of the show to inquire about possible organic detection using the Rock Abrasion Tool (RAT) from Spirit and Opportunity. We concluded with Dr. Levin suggesting we contact NASA to release information about the green spots on Mars and liquid organic analysis of the surface. Also during this segment and not related to Mars, a listener asked Gil a few questions about his WW2 experience in the Merchant Marine in the N. Atlantic and the Pacific.  It was an interesting digression and I still found a way to connect it to space and Mars!

Guest:  Dr. Pascal Lee.  Topics:  Dr. Lee discussed HSF for Mars, pending Mars mission, Mars science, Earth analogs & his new book, “Mission Mars.”  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 Dr. Pascal Lee back to the program to discuss HSF to Mars, pending Mars programs, his new children’s book, “Mission Mars” (www.scholastic.com/missionmars).  During the first segment of this 1 hour 58 minute program, Dr. Lee talked about our operating Mars rovers, Opportunity and Curiosity.  He talked about Curiosity looking for organics and the confusion over not finding methane.  I then asked our guest about the two potential HSF missions to Mars, Mars One and Inspiration Mars.  As you will hear, Dr. Lee was highly skeptical regarding Mars One and suggested it might not be good for the “cause.”  He was supportive of Inspiration Mars and had much to say about that mission and the likelihood of survival for the astronaut couple on board.  I asked him what he thought the impact on HSF and especially humans to Mars mission would be if the Inspiration Mars crew died.  He offered an interesting perspective on this depending where along the mission the crew died.  We also talked about possible NASA involvement in Inspiration Mars plus the challenges in the reentry given the capsule’s high speed coming back from Mars and entering our atmosphere.  I also asked if Inspiration Mars put a damper on many of the Phobos-Deimos mission plans.  Pascal was asked about the Mars One business plan modeled on the Olympics and virtual reality TV shows.  Pascal was not optimistic that such a plan could drive a Mars mission but did think there might be a place in a human Mars mission for a TV show.  Pascal then described the hostility of the Mars environment for human life. This is an interesting factual analysis of what the Martian environment is like & what it would mean for human survival.  Near the end of the first segment, we talked about Pascal’s first book, “Mission Mars” which is aimed for the 9-12 year old market.  Make sure you visit the book’s interactive website, www.scholastic.com/missionmars.  The book is officially released in November but teachers & others can order it now from the Scholastic site.  I also asked how he explained the potential for alien and microbial life to young kids, along with the risks to humans going to Mars.

In our second segment, we started off discussing the Drake Equation. Dr. Lee explained in detail why he believes that N in the equation is a very small number.  In summary, even if there are other intelligent worlds out there, they may be so few in number and so far away that for all practical purposes we are alone in the universe so we better be good stewards of what we have with Earth.  Pascal mentioned the dinosaurs in terms of the evolution of life on Earth and he noted how long it took for something like modern day humans to evolve (around 4.5 billion years).  Some listeners asked him if we were not so different from the dinosaurs given the violence and killing humans do to one another.  Next, we talked about the Humvee expedition as a Mars analog across the North West passage.  Known as the Northwest Passage Drive Expedition, this was an amazing trip.  A documentary was made and will be available next year. I will let listeners know when it is available.  From fuel to cold to polar bears to almost losing the Humvee by falling through the sea-ice, this was quite the expedition over a three year period.  Note what Dr. Lee said about the expedition challenges in comparison to what it would be like to living on Mars.  Briefly, as hard and challenging as the North West Passage Expedition was, it would be nothing compared to living on Mars!
