We welcomed Dr. John Rummel to the program to continue or discussion on planetary protection, specifically humans to Mars. During the first segment of our 90 minute program, Dr. Rummel introduced us to the problems existing at this time regarding humans to Mars. He said HSF to Mars at this time would probably be prohibited by planetary protection rules but that would change as we learned much more about Mars. He talked about humans going to Mars and being able to do something useful on the surface, not just sit in the hab for the most part. To be able to do something useful means we need much more information about Mars. He said we travel with molecules, then he cited some examples of the unknowns regarding contamination with our molecules both as to what may be on Mars and to the safety of the Martian crew. He also talked about using the Moon as a training ground to help us be better prepared for eventually going to Mars with a crew. BJohn sent in an email saying life on Mars could not be disproven so what are we waiting with respect to planetary protection issues? Don't miss how our guest responded to BJohn's question. Our guest suggested we not be impatient about getting humans to Mars and again he stressed that we have no EVA systems for Mars, no clear EDL system, and that for now we cannot do useful things on the surface of Mars. Make sure you hear all that he has to say on this subject for the full context of his comments. Dr. Doug sent in an email about cross contamination issues concluding that "we should just accept that there has been bilateral biological exposure between the planets for eons and so at some point we have to just accept that and go ahead and send people to live on Mars." Don't miss John's reply. In the second segment, Paul asked about Mars One and SpaceX timelines for humans to Mars. Our guest said that the rules would not prevent private parties from going to Mars and be productive. He also brought up some of the criticisms of contamination issues as expressed by Dr. Zubrin. Since our guest had been a consultant to Mars One, I asked him about their plan to go in the early 2020s. John had much to say during the show and in response to this question about Mars One. At one time he even suggested we consider supporting their effort and why. Thomas called in from Singapore to talk about a hard landing accident on Mars and contamination from that type of accidental landing. John had much to say about risk taking, testing of equipment and the ultimate no risk position of never landing an anything on Mars. Listen to the entire discussion so you don't take anything out of context. It was a very interesting given and take. It is worth pointing out that Johnt again talked about the need to be productive on the surface of Mars and for that we need lots more information about Mars. Sample return missions came up.

Chris Carberry, Rick Zucker, Monday, 3-21-16  

Guests: Chris Carberry, Rick Zucker; Topics: Humans two Mars, the Explore Mars, Inc. upcoming summit, Affordable Mars Workshop & more. Please direct all comments and questions regarding specific Space Show programs & guest(s) to the Space Show blog which is part of archived program on our website, www.thespaceshow.com. Comments and questions should be relevant to the specific Space Show program.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed Chris Carberry and Rick Zucker to our 90 minute discussion. During the first segment, I asked our guests about three recent topics discussed on The Space Show that were relevant to humans going to Mars. The three topics included planetary protection, why go to Mars first rather than learning and proving out technology by first returning to the Moon, and where was there a viable policy for humans to go to Mars? We spent most of the first segment addressing these three areas. On the topic of planetary protection, Chris had some interesting things to say. The subject is taken seriously, it is continually discussed and he and others see it as an evolving issue. He believed that there would have to be risk adjustments and modifications as more information about humans to Mars becomes known. He also said that were humans permitted to go to Mars but only to places of little or no interest, one would have to determine if it was worth doing a human Mars mission to such a location. This was a fascinating discussion, don't miss it. As for the Moon, as I said to Dr. Benaroya on Sunday, Mars advocates do not see the Moon as an essential first step for going to Mars. While Mars first advocates do not oppose going to the Moon, they say by landing humans on the Moon, the risk is that the program to Mars gets sidetracked, maybe even for decades. Chris advocated cislunar development without landing on the Moon. As I suggested to our Sunday guest, Mars first advocates believe that if the goal is to go to Mars and they say that is the goal, then one should go to Mars, not some other destination. Regarding the absence of a Mars policy, both Chris and Rick talked about how the issue for humans to Mars has been improving along with more and more interest in congress as confirmed by their recent legislative blitz. Our guests also referenced the upcoming third edition of the Affordable Mars Report, out in about two weeks, as further evidence of a humans to Mars policy that is evolving for the better each year. During this segment, our guests talked about the upcoming Humans 2Mars Summit planned for May 17-19 at GWU in Washington, DC. Several of the main speakers and events were discussed. You can find out more about this event and the free streaming of it by visiting http://h2m.exploremars.org. Before the segment ended, Bonnie in Atlanta wanted to know if Explore Mars was reaching out to the presidential candidates. Our guests talked about their outreach activities in this area plus they said that after their big May event, they would have teams going to congress for more legislative educational efforts for the eventual humans to Mars mission. The final questions of the segment dealt with our TRL for going to Mars at this time, plus a time line for a realistic launch date for a humans to Mars mission.

Robert Walker, Monday, 3-7-16  

Guest: Robert Walker. Topics: Planetary protection and human spaceflight to Mars. Please direct all comments and questions regarding specific Space Show programs & guest(s) to the Space Show blog which is part of archived program on our website, www.thespaceshow.com. Comments and questions should be relevant to the specific Space Show program.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed back to the show Robert Walker from the UK to address questions about human spaceflight to Mars, planetary protection, Article IX of the OST, and human contamination of Mars if life or past life is found on Mars. During the first segment of our 1 hour 48 minute discussion, Robert described the problem and he expressed his opinion that not only should humans not go to Mars if simple life, complex organics, or past life are found to be there as due to the high risk of human contamination and the damage to science. Robert spent most of our first segment going into detail about the problem, explaining why human contamination would be spread around the planet by winds & dust storms so no location would be OK for humans given the Mars life scenario. He also spent time during this segment talking about options for humans including lunar settlement and asteroids. Robert has also written extensively on this topic. You can read his material at www.science20.com/robertinventor. Several listener questions challenged Robert given SpaceX and Elon Musk plans for HSF to Mars, the Mars One venture and even the NASA Roadmap to Mars. In addition, Robert was asked about very bright space aware professionals working for humans to go to Mars and live there including Dr. Zubrin, the Explore Mars organization, and others wanting to change our National Space Policy to focus on settlement, especially settlement on Mars. Robert talked about a disconnect with these plans and their rhetoric from the planetary protection, UN policies, and the Outer Space Treaty. Robert took time during this segment to talk about planetary defense and the risk of an impact on Earth because he wanted to debunk the idea that we had to start a settlement on Mars to save the human species by having a backup on Mars. What do you think of what Robert had to say on this topic? Post your thoughts on TSS comments section for this show on the website as we want to know how you view these issue. In the second segment, I asked Robert if he would approve of humans to the Martian moons, orbiting Mars in a Martian space station like vehicle, and robotic exploration of the Martian surface. Robert thought this was how Mars exploration should be carried out. Listen to what he said for these alternative exploration plans. Do you agree with him? Also in this segment, we talked about the sterilization process and why he thought humans could not be made contamination free with current technology. He addressed the issue of space suit leakage by design as well, including the loss of some atmosphere through the airlock to Mars which might have the potential of transferring contaminants to Mars. Later in this segment, Rhonda asked about rogue nations offering to launch humans to Mars for money despite planetary protection rules and policies.

John Strickland, Friday, 2-26-16  

Guest: John Strickland; Topics: HSF to Mars, setting up a Mars colony, reusability & retro-propulsion landing. Please direct all comments and questions regarding specific Space Show programs & guest(s) to the Space Show blog which is part of archived program on our website, www.thespaceshow.com. Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed John Strickland back to the show to discuss Mars colonization with transportation to and from Mars. During the first segment of this 1 hour 31 minute discussion, we started out by John responding to my question about our current TRL for getting humans on Mars. This opened the door for John to talk about our TRL today as well as in the near future, entry, descent, and landing on Mars which he said was solved by landing with retro-propulsion, plus he made many additional claims in support of getting humans to Mars fairly soon. I pointed out to John that the retro-propulsion landings for Mars were far from operational nor was the problem solved, then I suggested he listen to the upcoming show Rob Manning who is one of the architects of this type of potential landing on Mars. John based his conclusion on retro-propulsion landings on Mars on SpaceX first stage recovery and to some degree, the same for Blue Origin. Let us know what you think about this by posting your comment on the blog. John also talked about propellant depots and their usage for Mars HSF missions. John described his concept of a high mass mission and why. This prompted Doug to check in with us with a series of questions throughout the show regarding John's ideas. Crew safety was another topic during this segment. This was followed by Joshua asking about the economic drivers for the Mars mission John was talking about. Don't miss what John said in response to Joshua's question. In the second segment, John was asked if we should first go to Mars or do an O'Neill colony. John suggested both should be done ASAP. Don't miss his explanation. BJohn asked John about the Martian moons. John had much to say about the mons and how best to go there and use them to facilitate the humans to Mars missions. Jack emailed in a question about the recent House Science Committee hearing on the Space Leadership Preservation Act that featured Dr. Mike Griffin and Col. Eileen Collins answering the congressional questions. Jack's purpose in referencing the hearings was to ask John what he thought of Mike's response dealing with when we will be ready to send a crew to Mars. You can watch the 2 hour 15 minute hearing at https://science.house.gov/legislation/hearings/full-committee-hearing-space-leadership-preservation-act-and-need-stability. Doug joined in with email comments about a Mars flyby mission saying to do that with a crew would not require the testing program Mike suggested for humans to Mars. Later in the segment, John was asked if he was hearing credible rumors about the SpaceX plans to go to Mars which will be announced at the September IAC meeting in Mexico. John talked about different versions of SpaceX rockets that might be involved but he had nothing specific to say about the SpaceX plans. So we all wait for the big announcement.

We Are The Martians: Start Up Planet  

For Radio 4's Mars series, Kevin Fong asks: what future do we have on Mars when we finally get there? He talks to scientists and writers about their visions of a human presence and purpose on the Red Planet. This is the third part on this series on our relationship with Mars. The American space agency NASA aims to get the first human crew to Mars sometime in the 2040's. It is likely to be an international mission and carry a crew of six people. Elon Musk, the founder of private rocket company SpaceX, has unveiled a scheme to get a spacecraft of one hundred colonists to the Red Planet before 2030. Do we go to Mars for the big science questions and exploration? Or is Project Mars about becoming a multi-planetary species, extending the American western frontier by a hundred million miles? Do we need to prepare Mars as a refuge should civilisation face extinction here on the home planet. Even the first boot print mission will be the mother of all camping trips, and full of hazard. Mars' tenuous atmosphere contains no oxygen, the average temperature is -60 degrees Celsius, the surface is bathed in cosmic and solar radiation and toxic dust lies all over the planet. So some Mars enthusiasts predict that our presence there will never amount to more than something like extraterrestrial Antarctic style bases, where visiting scientific explorers and back-up technicians live and work for a few years at a time before returning to Earth. But for others, the vision is much grander and more ambitious. Colonies will become city sized and economically productive, trading technological innovations with the home planet. Generations of people will live and die in societies free from oppressive authority on Earth. Kevin Fong hears from would-be Martian explorers such as Elon Musk and Robert Zubrin. Robert Zubrin is president of the Mars Society and is credited with coming up with the basic technical strategy for mounting a return trip to Mars which both NASA and Space X have adopted. If we do this in our generation, says Zubrin, within two centuries there will be self-sustaining communities on Mars with their own dialects, cultures of technological and artistic invention, and their own history of 'heroic deeds'. This is romanticism to others such as Oliver Morton, author of 'Mapping Mars', and that Mars is no place for civilians. let alone children. With gravity little more than one third of Earth's, a successful human pregnancy may in fact be impossible. That's one of the many unknowns about the future of humans on Mars revealed, as Kevin talks to the scientific Mars visionaries such as Chris McKay of NASA Ames Research Center and Pascal Lee of the Mars Institute, and to science fiction authors such as Kim Stanley Robinson, Emma Newman and Stephen Baxter who've imagined people on the Red Planet.

Dr. Erik Seedhouse, Monday, 4-1816  

Guest: Dr. Erik Seedhouse. Topics: We discussed his book "Mars Via The Moon" plus timelines for our TRL for enabling a human to Mars mission. Please direct all comments and questions regarding specific Space Show programs & guest(s) to the Space Show blog which is part of archived program on our website, www.thespaceshow.com. Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information. In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed Dr. Erik Seedhouse back to the show to discuss his new book, "Mars Via The Moon." Our 1 hour 51 minute discussion did not have a break due to a very active discussion with Erik and listener emails so we are nonstop for this nearly two hour Space Show program. Erik started the discussion by saying it might take 20-40 years to develop the technologies for our sending humans to Mars. I asked him to elaborate on the 40 year component of the timeline and that opened the door for Erik to discuss the challenges facing humans to Mars. Erik discussed the need for closed loop life support, a tested and functioning EDL system for very large payloads, O2 generation, radiation mitigation strategies, artificial gravity or other microgravity mediation techniques and solutions to vision problems. He also talked about other challenges as well. Keep in mind That at no time did Erik say there were show stopper challenges, just difficult challenges. He also talked about the crew needing to land on Mars ready to start working. He compared and contrasted that requirement with the reality of crew condition coming back from the ISS or the older space shut as often the crew needed to go through a type of rehab to start working again. He said there would be no rehab facilities or help on Mars. Erik then made the case for testing hardware and technologies on the Moon first. He suggested that since we are years if not decades away from humans to Mars, we should use the time to develop technologies, techniques, hardware and procedures for living and working in space on the Moon. As you will hear, many listeners challenged him on this because they said there were too few similarities between the Moon and Mars to render the Moon less than desirable as a Mars training ground and facility. Do you agree with the listeners challenging Erik or do you agree with Dr. Seedhouse? Let us know on the blog. Dr. Seedhouse was asked specific questions about radiation, ISRU, and Mars EDL. Don't miss how Erik handled these questions and concerns. Dr. Doug emailed about first doing a Mars flyby mission and suggested remedies for one vision problem, cataracts. Also in this discussion, Arnold asked about humans going to Venus to settle a cloud city rather than going to Mars. Don't miss what our guest had to say about Venus and cloud cities. We fielded several emails from our friend Gerald Everett in Florida dealing with Red Dragon, cataracts, having ESA do lunar missions and the US lead the way to Mars, on orbit centrifuge studies, and intracranial pressure as one of the vision issues. BJohn also sent in notes about ISRU and he kept trying to make the case that there were too many differences between the Moon and Mars for the Moon to be a good analog for humans to Mars.

Dr. Erik Seedhouse, Monday, 2-8-16  

Guest: Dr. Erik Seedhouse; Topics: We discussed Erik's book, "SpaceX's Dragon: America's Next Generation Spacecraft" & humans to Mars. Please direct all comments and questions regarding specific Space Show programs & guest(s) to the Space Show blog which is part of archived program on our website, www.thespaceshow.com. Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

Space Show programs can be quoted, but the quote must be cited or referenced using the proper citation format. Contact The Space Show for further information. In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed back Dr. Erik Seedhouse to discuss his new book, "SpaceX's Dragon: America's Next Generation Spacecraft." During the first segment of our 1 hour 35 minute program, Dr. Seedhouse opened up by saying that SpaceX had one purpose only, for Elon to go to Mars and bring others there to settle on the Red Planet. During our discussion, Erik received numerous questions by email from Tony and Rome who used the website Disqus program posting on the comments section as his email questions for the guest. Their questions continued through the entire discussion. Also during this initial segment, other listeners had questions about the Dragon V2 flight schedule, other models of the Dragon including those planned for use in Mars missions, Orion, and the Boeing CST 100. Jack sent in a question asking if the SpaceX-Musk Mars mission and settlement rhetoric was different from the rhetoric put forth by the Mars One group. Don't miss how our guest responded to this question. Erik then received questions about the SpaceX Draco rockets but as you will hear, Erik was clear in stating that Dragon V2 was not for Mars and the Mars version of the Dragon was still an unknown. Erik spent a good amount of time discussing the various Dragon configurations so don't miss this discussion. One point Erik made over and over again dealt with the rapid development time SpaceX has incurred for Dragon, especially when compared to the time it has taken the government to develop Orion. In addition, our guest talked about the high costs for developing Orion plus the fact that the CST 100 is for the ISS only, not for going to Mars. In the second segment, Dr. Seedhouse said a goal was needed and Mars was the goal. He was asked about SpaceX plans for Mars, human factors, artificial gravity, and such. Erik said that information was not known but we both talked about anxiously awaiting the SpaceX Mars plans when they are announced later this year at the IAC in Mexico. In this segment, Erik mentioned using a Dragon for a Mars Sample Return Mission. Dr. Dwayne Day called and wanted to know who would pay for the Mars Sample Return Mission. Erik mentioned that NASA might join in given what he has been reading and hearing in the space world but Dwayne pointed out there was no funding for a sample return mission and the Decadal Survey had not planned for the actual return of Mars samples, just the collection of them with Mars 2020. This resulted in an extensive discussion with our guest and caller over assumptions, what SpaceX may or may not be able to do including landing on Mars using EDL techniques. Retro-propulsion came up and was discussed. Dwayne pointed out that SpaceX did not have this talent so he would have to partner with those that had it or bring on employees with this talent.

FACE AND PYRAMIDS ON MARS  

Mars has fascinated many of us here on Earth for centuries and beyond.  It is one of the bright objects in the sky that has a visible color, which obviously attracts attention, and early astronomers believed that there were canals on Mars that perhaps did not occur naturally.

Mariner 9 arrived on Mars on November 14, 1971 and was followed within a month by the Soviet probes, Mars 2 and Mars3.  After the dust settled  dry riverbeds, a canyon,  extinct volcanoes and fog were all visible.  On February 8, 1972 Mariner 9 returned a photo that looked very much like pyramids.  Could this be a sign than some living civilization existed on Mars in the past and built these pyramids and other stuctures?  More exciting information was to follow.

In 1976, two "flagship class" probes arrived at Mars: Viking 1 and Viking 2.   Each was an orbiter/lander pair.  The orbiters surveyed the planet in much more detail than Mariner 9 had been able to do.  In addition to obtaining better resolution images of the pyramids at Elysium Planitia, they also found some more in a region called Cydonia Mensae.  As exciting as the first pyramid discovery had been, this really took off in the public imagination, for in addition to what seemed like a complex of pyramids,  there was a gigantic face.

Richard Hoagland is a former member of the JPL press corps, and the author of "The Monuments of Mars".  Hoagland has led a long investigation into the Viking data.  He and his team have analyzed different photographic frames, taken at different angles, weeks apart.  He claims that he and his researchers have considerable evidence that the "face", as well as some nearby pyramid-shaped objects and other "artifacts," are the work of sentient creatures.

In any event, speculation exists that life once existed on Mars and  former residents on Mars, for whatever reason, a long time ago may have decided to relocate to Earth.

Eileen Collins, Friday, 4-15-16  

Guest: Eileen Collins; Topics: Human spaceflight, U.S. space policy, Mars, space shuttle, ISS, and much more. Please direct all comments and questions regarding specific Space Show programs & guest(s) to the Space Show blog which is part of archived program on our website, www.thespaceshow.com. Comments and questions should be relevant to the specific Space Show program.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed Retired USAF Col. Eileen Collins to the program. Col. Collins is also a retired NASA astronaut having been both the first woman pilot and first woman commander of a space shuttle. During the first segment of our 95 minute discussion, I asked our guest about the differences in flying to and from MIR and the ISS, plus docking. I also asked Col. Collins what it was like being inside Mir. You might be surprised by what she had to say about both MIR and the ISS, especially when comparing one to the other and how one approached and docked with each space station. Its an interesting discussion which you don't hear that much about so listen up so you don't miss anything. We next talked U.S. space policy. Col. Collins said that our space policy should be vetted, public, and very transparent. It should also include input from interested citizens. She said that the policy makers should "stop changing things on us!" Listen to her explanation of that statement. Our guest cited several examples to make her case about changing things. Eileen wants to go to Mars and would like to see the U.S. lead the Mars venture. She also said she would like to see a U.S. astronaut be the first one to set foot on Mars. Listeners asked her about an international partnership for a human Mars mission and would she be OK if an American was not the first on Mars. Don't miss her answer to that question. We briefly talked about planetary protection Mars. Her bottom line was that being a former test pilot, she believes the people involved would "figure it out." She does not see planetary protection preventing humans on Mars.We briefly talked about her recent House testimony and the Space Leadership Preservation Act that would provide for a ten year term for the NASA administrator so as to remove politics from NASA. Eileen explained why she thought ten years might be too long but was in favor of five year term. In talking about NASA space projects, she gave high praise to the robotic and science missions and said that astronauts support these missions as the unmanned part of NASA was very important. Besides Mars, other destinations of possible interest that were mentioned included Europa and Venus plus the Martian moons. She also had high praise for the Kepler mission and talked about the exoplanet discoveries which she said were very exciting. Todd from San Diego asked if she were selected for a mission to Deimos instead of actually going to and landing on Mars, would she be disappointed that she was not actually going to Mars. Don't miss what she had to say in response to this question. Following Todd's question, Jack sent in a note asking her if she would consider going to Mars on the much talked about SpaceX humans to Mars mission were she asked to be part of the mission. Again, don't miss what she said about going to Mars via SpaceX. Read the rest of the summary @ www.thespaceshow.com.

A Trip Around Mars with Kevin Fong  

The planet Mars boasts the most dramatic landscapes in our solar system. In a programme first broadcast in March, 2013, Kevin Fong embarks on a grand tour around the planet with scientists, artists and writers who know its special places intimately - through their probes, roving robots and imaginations. As we roam Mars' beauty spots, Kevin considers why the Red Planet grips so many. Beyond its alien topographic grandeur, Mars inspires the bigger questions: are we alone in the cosmos, and what is the longer term destiny of humanity? Was there more than one life genesis? Will humans ever live on more than one planet? The itinerary includes the solar system's greatest volcano - Olympus Mons. It is an ancient pile of lavas more than twice the height of Everest, with a summit crater that could contain Luxembourg. The weight of Mars' gargantuan volcanic outpourings helped to create the planet's extreme version of our Grand Canyon. Vallis Marineris is an almighty gash in the crust 4,000 kilometres long and seven kilometres deep. That is more than three times the depth of Earth's Grand Canyon. In some place the cliffs are sheer from top to bottom. A little to the east lies an extraordinary region called Iani Chaos, a vast realm of closely spaced and towering rock stacks and mesas, hundreds to thousands of metres high. One researcher describes it as Tolkienesque. This unearthly shattered terrain was created billions of years ago when immense volumes of water burst out from beneath the surface and carved another giant canyon, known as Ares Valles, in a matter of months. Imagine a hundred Amazon rivers cutting loose at once, suggests Professor Steve Squyres. The catastrophically sculpted landscapes are part of the plentiful evidence that in its early days, Mars was, at times, awash with water and, in theory, provided environments in which life could evolve and survive. That is what the latest robot rover on Mars - Curiosity - is exploring at the dramatic Gale Crater with its central peak, Mount Sharp. Expert Mars guides in the programme include scientists on the current Curiosity mission, and on the preceding rover explorations by Spirit and Opportunity. Kevin talks to hard sci-fi novelist Kim Stanley Robinson whose rich invocations of Martian landscapes form the narrative bedrock of his Mars Trilogy. He also meets Bill Hartmann, a planetary scientist since earliest generation of Mars probes in the 1960s and 1970s. Bill has a parallel career as an artist who paints landscapes of the Red Planet. Planetary scientist Pascal Lee of the Mars Institute begins Kevin's tour with a painting he created - an imagined view of Mars from the surface of its tiny moon, Phobos. Producer: Andrew Luck-Baker

We welcomed Dr. Pascal Lee back to the program to tell us about The Northwest Passage Drive Expedition, what they learned that can be useful for crews going to the surface of Mars, including how to select a Martian crew and more. A documentary film, "Passage To Mars," was made of this expedition which we also talked about. During the first segment of our 90 minute discussion, Dr. Lee talked about the infrastructure needed for the expedition including vehicles, supplies, and the terrain that they would be traveling across. Several times during this segment as well as the second segment, he stressed the need for two vehicles in case one got stuck or had a breakdown. The expedition used specially equipped Humvee's. Pascal also talked about the fact that it took three seasons to complete the expedition. Our guest described traveling across sea-ice which was surface used by the expedition. Listener Jack asked Pascal how similar the expedition terrain was to Mars. Our guest said that Mars was more dangerous and confined. For example, the Northwest Passage Expedition did not travel in a lethal environment but there were also some similarities. Pascal talked about how Mars was more treacherous and why. Ben asked about radiation since traveling far north on Earth exposes people to higher doses of radiation. Our guest had much to say about this topic, measurements taken at Devon Island, and areas on Mars where Curiosity has show not so much radiation but then other areas on Mars where the cosmic rays mix with the Martian soil with hydrogen for much greater radiation levels. Listener Carl asked about crew issues. Pascal listed five standards that should be considered when selecting a crew, even for Mars. I suggest you make note of the five standards as we will be talking about them on future Space Show program. In the second segment, our first question came from Mohammad in Amman, Jordan inquiring about Pascal reaching out to other Mars advocacy organizations and individuals to do scientific research on their expeditions and missions. Pascal had much to say about this, especially in support of SpaceX and Elon Musk and just the opposite with Mars One. Don't miss all of Pascal's reply to Mohammad. Linda wanted to know about lessons learned and applying them to the Martian moons. Pascal was a big supporter of going to the Martian moons first so be sure to listen to what he had to say about this subject. He did say going to the Martian surface was a tall order. Pascal mentioned that there were about 50 sites being considered for the first Mars human landing site. I asked him how planetary protection might alter these plans. This caused our guest to tell us about the microbiology study that they did regarding possible contamination on the expedition. They published there findings in the June issue of Astrobiology.

Dr. John Brandenburg, Tuesday, 2-16-16  

Guest: Dr. John Brandenburg; Topics: The New Mars Synthesis: the new concept of Mars past, evidence for life.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed back Dr. John Brandenburg for the third and final part of his Space Show Trilogy for early 2016. During the first segment of our 2 hour 10 minute program, Dr. Brandenburg talked about early Mars history and geology to pave the way for making the case for some type of past life having been on Mars with probable life there today. Dr. Brandenburg's discussion was at times technical with lots of focus on there once having been an ocean in the northern part of Mars, the chemical makeup of the Martian atmosphere in the past and present, Martian meteorite analysis, and more. Listen carefully and let us know what you think. At times I asked Dr. Brandenburg to compare and contrast his views with the more orthodox Mars views. Don't miss how he did this comparison. Rather than going into the detail with all the analysis provided by Dr. Brandenburg, I simply urge you to listen carefully, take notes for later due diligence and research on your own if you are so inclined, and then share your findings and analysis with us in the comments section below. Email questions and calls for Dr. Brandenburg were on the light side for this program. That said, John did get asked about planetary protection and could that be a reason for not announcing past or present life on Mars. Dr. Brandenburg discussed this as a possibility both in this segment and our second segment. Doug sent in an interesting email asking "does it matter to the question of life elsewhere if life on Mars was found to be related to Earth life versus being a second genesis?" Don't miss what our guest said in response to Doug. Before this segment ended, Dr. Brandenburg said that Primordial Soup Theory of how life began was wrong and no longer valid. He talked about life coming from elsewhere for both Mars and Earth (about the same time) from spores. He elaborated on this here but also to some degree in the second part of the show. In the second segment, John said we were maturing as a species, we were not alone in the universe, and we needed to accept it. He called it the Second Copernican Revolution which he said was a problem for some because they see it as a demotion of importance for humans. He had much to say about this during this segment of our discussion. It was a topic that he kept coming back to until the end of the program.Dr. Brandenburg talked about the Viking landers, perchlorate & life detection on Mars. He also was more specific about Mars atmospheric gasses which took him to making the suggestion that photosynthesis was happening on Mars. Listen to his explanation. What do you think? Let us know by posting a comment on our blog. Kathy in Seattle asked John if he thought a past or present life announcement would be made within a few years. Our guest said yes and told us why he thought that such an announcement would be forthcoming soon. Read the rest of the summary @ www.thespaceshow.com.

We welcomed back to the show Dr. William (Bill) Farrand to discuss the Mars rovers, particularly Spirit and Opportunity which landed on Mars 12 years ago this month. In the first segment of our 1 hour 29 minute show, Dr. Farrand, a member of the Spirt/Opportunity team, updated us on the latest info coming back from Opportunity and he again told us what happened to Spirit to cause it to cease operating. Opportunity is very exciting and to see it still working 12 years later when it had an original life expectancy of about six months is quite amazing. We talked about the Opportunity team, the new information coming back from the rover, the science being done & the discoveries made by these two rovers over the past dozen years. Our guest took some questions about the move The Martian. While liking the movie, he said that the Martian landscape and terrain were not very realistic nor was the Pathfinder landing site. Later in the program, he was asked about Martian dust storms and he explained why the dust storm in the movie's opening scene was inaccurate. Don't miss his comments. Karen asked our guest to list off some of the top Opportunity discoveries which Dr. Farrand did do. He was asked about Opportunity detecting signs of past life but said no because it was not designed to identify organic materials. In his response, he focused on the upcoming Mars 2020 mission which would be better designed for organic and other life detection type experiments. As part of this discussion, Charlie in Atlanta asked what life detection instruments on a robotic space mission would consist of & wondered why such instruments were not on other Mars rovers. Before the segment ended, another series of questions fielded by our guest dealt with comparing Mars geology to Earth geology. Dr. Farrand talked about similarities between Mars and Earth geology but he also identified differences in rocks & geologic features. One of the major differences focused on the absence of tectonic plates and movements on Mars which are largely responsible for earthquakes here on the home planet. He talked about Mars faults and mars quakes but its nothing like what happens on Earth. Volcanic issues between Earth & Mars were also discussed with comparisons made between the two planets.In the second segment, BJohn asked about mission instrument selection differences based upon destinations such as our Moon, Mars, Martian moons, or an icy moon of Jupiter. Luis from Venezuela wanted our guest to compare Martian exploration by virtual reality as compared to astronauts on the ground. Read the rest of this summary @ www.thespaceshow.com.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed back Dr. Catharine (Cassie) Conley, Director of the NASA Office of Planetary Protection, to explain and discuss planetary protection from both the U.S. and the international perspective. As you will hear, planetary protection is not just a perspective, it is an enforceable set of regulations developed since our early days of the space program and enforced by all members who have signed the Outer Space Treaty. We also learned that the UAE, now interested in space and a country that has not signed the OST, has been in touch with planetary protection offices to follow the planetary protection guidelines for their upcoming missions. The UAE will be complying with planetary protection rules and guidelines. Our 1 hour 23 minute discussion was carried out in one segment, no break. Dr. Conley started out by explaining planetary protection (PP), international participation, COSPAR and more. She went into past human history as to why PP was important citing what happened when Columbus brought Quartan malaria with him to the New World. She said that today, Malaria is a $5 billion a year expense for impacted areas and it can be traced back to the Columbus exploration. Our guest had much to say and many examples to reference in support of PP for Mars based on Earth examples. She said that Mars may not be as safe and friendly as many space enthusiasts think as even today there are many unknown and possible human risks associated with Martian planetary exploration, both in terms of human contamination on Mars and exposure to something on Mars that can hurt or kill humans. Rather than review this very detailed and comprehensive discussion, including excellent listener emails and calls, I urge you to carefully listen to this interview if you are at all interested in humans going to Mars. Contrary to what you might have heard, Article IX of the OST does not prohibit humans to Mars but strict guidelines have been developed and based on current science at the time of the planned human Mars mission, a determination would be made about the mission going forward. All of this was discussed in great detail with lots of listener questions drawing our guest out for even more detail. I will add that both SpaceX and Mars One have been in touch with PP & COSPAR offices and are paying attention to PP guidelines and the need for more and more science regarding human missions. I will also say that there are only three restricted possible human destinations at this time regrading PP, Mars, Europa, and Enceladus. Though I know I am being repetitive, I urge you to listen to this complete discussion with Dr. Conley if you are interested in a Mars human mission. Remember, such missions may in the future be approved to areas designated "safe" or "highly resistant" to human contamination of Mars plus risks to humans.

Rob Manning, Monday, 3-28-16  

Guest: Rob Manning; Topics: Human-scale Mars landers, supersonic retro-propulsion (SRP) for Mars landings. Please direct all comments and questions regarding specific Space Show programs & guest(s) to the Space Show blog which is part of archived program on our website, www.thespaceshow.com. Comments and questions should be relevant to the specific Space Show program.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed Rob Manning back to the show to discuss landing human-scale landers on Mars with supersonic retro-propulsion (SRP) or with other tools. During the first segment of our 1 hour 42 minute discussion, I asked Rob to define the problem regarding landing large payloads on Mars and to provide us with the definition of a large lander. A good portion of the first segment was a comprehensive discussion of these issues. Some of the topics included previous Mars landers, Martian atmospheric considerations, supersonic parachutes and Earth testing of them, vehicle entry mass, flying engines backwards as it is called, heavy lift, Mars landing areas and why, reusability, what is being learned from the SpaceX flyback booster reusability tests, and lots more. It was an information packed first segment and I suggest careful listening attention. In addition, you will likely find Rob's recent paper with several co-authors, "A High-Heritage Blunt-Body Entry, Descent, and Landing Concept for Human Mars Exploration" of interest and helpful in understanding the challenges for putting large payloads on Mars. You can download the paper at www.ssdl.gatech.edu/papers/conferencePapers/AIAA-2016-0219.pdf. Other topics in this segment included a question from Ralph about space advocate mission planning designs and if the actual mission planners ever pay attention to advocate proposals. Don't miss what Rob had to say in response to Ralph's question. It might surprise you. More was said about this in the second segment. Before the beak, Rob talked about the deceleration curve for g's regarding the return to Earth. He talked about how this can impact the crew and force significant design and engineering changes on the mission. In the second segment, Doug sent in a provocative email asking our guest "Might it be easier to accomplish great things in space than many assume?" Don't miss Rob's response to this question. By the way, part of Rob's response focused on the different ways SpaceX could do something and test it as compared to NASA. Later, Doug called in to ask our guest about deployable heatshields which might allow Mars landings to take place at higher up elevations. Again, don't miss what Rob had to say in response to Doug's heatshield question.Linda from Las Vegas asked for more information about the differences in landing large payloads or humans on the Moon or an asteroid compared to do it on Mars. Rob had much to say about EDL for all three destinations. Near the end of our discussion, our guest was asked about space advocate papers for planning missions or engineering and if such papers or proposals were considered by those actually doing the mission. Rob talked about the need for such papers to have some sort of critical feedback for the author as technical criticism is essential. Read the rest of the summary @ www.thespaceshow.com

John Strickland, Friday, 3-25-16  

Guest: John Strickland; Topics: Mars operations with high mass expeditions & robust bases, Oberth Effect, propulsion needs for Mars. Please direct all comments and questions regarding specific Space Show programs & guest(s) to the Space Show blog which is part of archived program on our website, www.thespaceshow.com. Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use. We do not permit the commercial use of Space Show programs or any part thereof, nor do we permit editing, YouTube clips, or clips placed on other private channels & websites.

In addition, please remember that your Amazon purchases can help support The Space Show/OGLF. See www.onegiantleapfoundation.org/amazon.htm. We welcomed back John Strickland for the third part of his three part series. For the third in the series, John focused "on Mars operations with high mass expeditions and robust bases, using the Oberth effect to massively lower propulsion needs for Mars. This also covered aero-capture, how to reduce propellant mass and increase expedition mass, base-first policy, crew safety, new interest in reusable ferries, and much more." During the first segment of our 97 minute discussion, John started out by talking about how to get to Mars, the use of cislunar infrastructure, especially at L1, and the use of multiple expeditions. Much of what he talked about in this segment was technical, especially when he addressed km/second needs for orbit, launch, orbit, landing. He was asked about ISRU by Dr. Doug so he spent time discussing that. Near the end of the segment, he was asked if he had a Power Point or otherwise written document summarizing what he was talking about as that would probably make following the discussion easier. He referred us to his 2011 publication which is on the NSS website, ACCESS TO MARS: (Part 1) EARTH TO MARS TRANSIT LOGISTICS ALTERNATIVES, an ISDC presentation from May 18-22, 2011. You can follow along by using this 109 slide document, www.nss.org/settlement/mars/AccessToMars.pdf. John discussed getting to the Martian surface with cargo as well as with humans, the use of different fuels, robotic missions and uses, ISRU, aero-capture, and even the use of advanced propulsion such as Vasimir. He also talked about his space ferry idea. In the second segment, we started with a question from BJohn about crew safety, suggesting that a "crewed Mars lander will carry its ascent stage fully fueled, and not use ISRU. This gives the crew the option to abort to orbit anytime during the landing sequence." John did not agree with his suggestion and explained why his plan provided better safety than what BJohn was suggesting. What do you think? Post your ideas on TSS blog. About seven minutes into the second half, John stopped the discussion to answer his cell phone. This provided an interesting first of a kind break on The Space Show as we heard John's side of the conversation. Moving on after John's phone call, Doug emailed in a question about John's reliance on reusability when it was yet to be proven. See what you think of John's reply. Again, let us know by posting your thoughts on TSS blog. John explained the Oberth Effect and "swing by maneuver." Doug sent in a follow up question asking John how long he suggested crews remain on Mars. John said around 500 days but it would depend on the transfer back to orbit. He then talked about both a conjunction class mission and an opposition class mission. In addition, he referenced zero boil off conditions or ZBO.
