We welcomed Matt Wallace from our Hotel Mars program to his first appearance on The Space Show.  During the first segment of our 90 minute program, Matt talked about his early mission assignments when he first came to JPL, then his shift to the Mars program.  We also talked about how the science missions and rovers are designed, managed, and eventually flown.  I asked our guest several questions about the science missions such as how a Deimos mission might differ from a mission to the surface of Mars.  Later, a listener asked our guest about a Europa mission and how that would differ. While there are clearly differences in the missions to different destinations, the trade process, planning, team organization and such all work pretty much the same.  We did spend some time talking about a Europa mission as that mission is a favorite for many of us, our guest included Most of the Europa mission discussion was in the second segment.  Matt talked about the new science instruments that will be on board Mars 2020, plus the extensive use of heritage hardware. He also said about 70% of the original MSL & Curiosity team would be working on Mars 2020, an important fact in managing the mission, costs and assuring mission success.  Matt was asked why it was so hard to confirm microbial life on Mars now or in the past & if there was one instrument that could do that.  This proved to be a fascinating and detailed discussion so don’t miss it.  Many listener emails addressed the rover control process.  There is no real time communication with the rover so Matt explained how they send commands to the rover, how the rover processes those commands and the safeguards built into it to protect the rover from accidents, etc.  He also talked about communication windows with Earth, when antennas are pointed toward Mars, and the busy DSN.  Listener Alex asked him about the book “The Martian” and wanted to know that were an astronaut stuck on Mars or needing some sort of emergency gear or something, could a defunct Mars rover be cannibalized for parts and made to work for the purpose needed by the person on Mars.  Matt’s answer might surprise you.  Several listeners wanted to know about a human Mars mission being more efficient for finding life signs than a rover.  Matt explained the trades involved. Doug emailed in a similar question during the second segment.  Matt said its not either or.  Instead, the rovers and a human mission are synergistic with one another.  As the segment ended, our guest was asked if NASA/JPL would consider partnering with a private human mission such as Mars One to use Mars One crew members for science missions.

In the second segment, we talked about other Mars rovers and mission including Maven and Insight.  Next, the question came in about Europa that was mentioned in the earlier segment.  Doug not only asked his robotic vs. human question but he sent in another question regarding the sample return mission and what methods might be used for collecting multiple samples.  He suggested a few different collection methods.  Matt said they discuss these types of options but in the end the trades opt for simpler missions for a variety of reasons.  See what you think of his answer & post your comment on the blog.  John, a high school student, sent in a note about colleges and the best path to be able to work in the space industry.  Barbara sent in a note asking if the EDL would be Seven Minutes of Terror Part 2 since they were using the same system as used for Curiosity or would it be less stressful.  Matt said they would still be nail biting all the way down.

We welcomed Rob Manning back to the program to discuss Mars Science Lab and the Curiosity rover plus his new book,  “Mars Rover Curiosity: An Inside Account from Curiosity’s Chief Engineer.”  Please remember to purchase this book through The Space Show/OGLF Amazon portal as Amazon will make a contribution to The Space Show for each purchase.  Instructions can be found on every blog and website archived program or you can email me.  During the first segment of our 90 minute program, we started talking about landing on Mars given Rob was last on the show in November 2009 regarding his paper on the challenges in landing large payloads on Mars.  We discussed Martian EDL, the MSL landing approach, the sky crane, and more.  I asked Rob about engineering errors & what they do at JPL to not make them as opposed to car engineers where there are usually multiple car recalls from most all brands. Don’t miss what Rob said about this, it might surprise you.  Rob then mentioned several errors & mistakes that they made, including incorrectly estimating the Martian gravity at the bottom of Gale Crater which ended up impacting their landing & of course the Curiosity wheels.  I also asked Rob for his thoughts on private Mars missions being able to land a big  payload or crew on Mars.  Listen carefully, his response may again surprise you.  Later, a listener asked Rob why Mars and if we were Mars obsessed.  Rob talked about our Mars culture and the good scientific reasons for our focus on Mars.  We also talked about other solar system targets plus radiation issues for the outer planets that were not as severe for Mars.  We talked about doing more, Titan, Europa, & the NASA budget.

In the second segment, listener Claudia asked about the biggest challenges in designing Curiosity, launching it, getting it to Mars. and Martian operations.  Rob said their concerns were born out, he talked about EDL, the sky crane.  Ben wanted to know if his concerns expressed in his paper referenced earlier turned out to be valid when actually designing EDL for Curiosity. B John emailed in several questions pertaining to Earth-Mars telerobotics & a Mars sample return mission back to Earth.  Near the end of our discussion, we talked about the new Mars 2020 project and finding life on Mars.

We welcomed author Rod Pyle back to the show to discuss his current book, “Curiosity: An Inside Look at the Mars Rover Mission and the People Who Made It Happen.”  Find out more about Rod and his books at his websites, http://www.rodpylebooks.net and http://www.rodpylemedia.com.  During the first segment of this 1 hour 27 minute program, Rod explained his long time interest in Mars and why he decided to write this excellent book.  I asked if NASA & JPL were cooperative with him in writing it and he said yes.  I asked him what impressed him the most about the Curiosity project and he said the Sky Crane to which he has devoted a full chapter in his book.  Rod then told us about the NASA Curiosity Mission Review Panel headed by Clive Neal at Notre Dame which suggested that mission management had enabled problems including getting a poor science return for the money and its lack of scientific focus and detail.  You can read about this review panel by visiting http://astronomyaggregator.com/exploration/nasa-panel-curiosity-planning-lacks-scientific-focus or simply Google Notre Dame Curiosity Mission Review Panel for additional panel commentary on Curiosity.  Listeners asked Rod about HSF to Mars and if after researching the mission, did he think the money spent on the project was worth it.  Rod provided some interesting budgetary comparisons and did say that he thought it was a good investment & program. He talked about the Curiosity mission goals, sedimentary rocks and Martian geology.  Future missions based on Curiosity were brought up, especially Mars 2020.  Another listener asked about using humans for Martian exploration instead of rovers.  He cited compelling financial facts between rovers and HSF which supported the use of Rovers, at least for now.  Another listener asked if he thought Curiosity was the best ever Mars mission.  His response might surprise you.  Prior to the break, he addressed a question about missions to the Martian moons.

In the second segment, Paula asked about ongoing mission operating costs and wanted to know if they were roughly equal for all the robotic missions.  Later, I asked if JPL had reviewed his manuscript. He said he sent it to them for fact checking but not content editing.  He also mentioned JPL reviewed it from an ITAR compliance perspective but did not “muzzle” anything.  A listener asked about the life expectancy of a rover team at JPL before moving on to another project or even leaving JPL.  Questions came in about SpaceX and its Mars plans, the both the SLS and F1 engine project came up for discussion.  Later, Rod said based on website hits, Pathfinder was probably the most popular of the Mars rover missions.  Another listener asked Rod to compare rovers from other nations to those built by JPL and NASA. As we were ending, he was asked about the Indian MOM mission and Maven.  His book “Curiosity” is packed with information such as we discussed plus much more in 32 chapters.  Remember, if you buy the book on Amazon, use the OGLF Amazon Portal so that Amazon will make a contribution to The Space Show. Instructions are on all website & blog archives plus both websites or just email me.

Please post questions/comments on The Space Show blog above.  You can reach Rod through his websites or me.

We welcomed Rod Pyle to the show to discuss his new book, “Innovation The NASA Way: Harnessing The Power Of Your Organization For Breakthrough Success,” plus we talked about our space policy, reusability, and other issues.  During the first segment of our 1 hour 52 minute show, Mr. Pyle started by giving us an overview of his background and experiences that led him to writing this book.  Specifically, Rod led leadership training at NASA’s JSC for executives.  From this background, he used the story telling format to illustrate NASA innovation.  Each chapter tells a different story, several of which we highlighted in our discussion.  Rod mentioned innovation at various NASA centers but did say JPL stood out for him.  When asked for the most innovative NASA projects, he talked about some projects that were left on the editor’s computer including the Apollo Guidance Control Computer but he did focus on and highlight the Lunar Module.  We also talked about NASA today and back in the Apollo days. Rod had much to say about this, including how today there seems to be a push for guaranteed results which of course do not exist.  He said NASA was known by three important key words:  Boldness, Daring and Passion.  Listeners asked about reusability and I mentioned a possible reusability moment similar to the previous Apollo moment.

In the second segment, we talked about his Viking chapter & the Viking experiments.  John from Ft. Worth called in regarding a smaller shuttle plan that might have been less ambitious – would it have been better? Questions came about NewSpace and innovating the SpaceX way!  Doug called and did not think that there would be a Reusability Moment like with Apollo but that reusability enhanced prospects for that type of moment, like a manned Mars mission.  Rod was challenged with questions from the perspective that Apollo was the wrong way to go to and develop space.  We talked about his forthcoming book, “Curiosity: The Inside Story” and our excitement over a potential Europa mission.

We welcomed Scott Lowther to the program to discuss his Aerospace Projects Review work for cancelled aerospace projects.  In the first segment of our 90 minute program, Scott introduced us to his work and his website http://aerospaceprojectsreview.com.  Also check out his blog at www.aerospaceprojectsreview.com/blog.  In explaining what he does, he talked about the larger aerospace companies, their dismissal of old records and materials, their lack of saving and archiving even important files and plans.  Boeing was the one exception to this practice.  He then described his experience at the Boeing archive library & the type of data he found there, including hardware samples.  We talked about why companies don’t save and archive material. Besides the more typical reasons including costs, space, and things like that, he said that there might be some documents that an attorney could get a hold of in researching a liability case and use something in the report, even a 20 year old report, as cause against the company in possible litigation.  Scott also talked about companies using a storage facility under control and management of Iron Mountain Data and Storage Backup.  One of his favorite projects was the X-20 Dyno-Soar and we talked about this vehicle project in detail.  On his website, you will also see his U.S. Bomber Series drawings and information.  In discussing this series, our guest was asked what the first U.S. bomber was.  He cited a biplane bomber used against Pancho Villa.  We talked about specific aviation projects such as the A-12 Flying Wing.  Another favorite project was the Orion nuclear propulsion vehicle of which our guest had much to say.  Toward the end of this segment, Anthony called in to talk more about the X 20.

In the second segment, we started out with Scott providing us with the mechanics of his website, products he sells, signing up for info on his email list, blue prints for famous projects such as the Saturn 5, and more.  Scott was asked about the impact of ITAR regulations on archiving material and he shared a KSC story about this with us.  Later in the segment, we talked about the smaller private companies saving material and projects that were cancelled or not developed.  He said this was up to the companies and they may not do it for cost and space reasons.  He mentioned that he did have good information on the Kistler Aerospace project.  He was then asked about the NASA HL20 lifting body.  Toward the end, he talked about the NASA Technical Reports Server (http://ntrs.nasa.gov).

Please post your comments on The Space Show blog above.  You can reach Scott through my email address.

We welcomed back Dr. Anita Sengupta to discuss the Cold Atom Lab (CAL) project for which Dr. Sengupta is the project manager.  CAL is to launch to the ISS in early 2016, probably aboard the SpaceX Dragon though that has yet to be confirmed but the project needs a ride on a pressurized spacecraft.  For more information on the CAL project and mission, check out these websites: http://coldatomlab.jpl.nasa.gov; http://coldatomlab.jpl.nasa.gov/news/FunPhysicsResearch. During this 64 minute discussion, Dr. Sengupta explained the CAL project to us, ultra cool quantum gasses in absolute zero and in zero gravity to establish a Force Free Environment which means no gravity pull.  We talked about laser cooling and the series of experiments likely to be done on the ISS with CAL based on the NASA Research Announcement which has a submittal date of Nov. 5, 2013.  We talked about atomic physics and many related topics, including the mechanics of the project, the need to place CAL in a rack as close to the center of gravity on the ISS as possible for the closest point to zero gravity. Listeners asked lots of questions about CAL, but they also had questions for Anita  regarding her expertise in entry, descent, and landing (EDL) from her recent work with Curiosity and the super sonic parachute.  In talking about human spaceflight, at one point Anita remarked that CAL was a hybrid project as it is definitely a robotic science mission but they interface with the ISS astronauts so CAL and the team have feet in both worlds.  In talking about the CAL hardware, we learned it was designed as an ORU, an orbital replacement unit.  Doug called in regarding EDL on Mars from Phobos and the use of strategically placed propellant depots in orbit around Mars and how that might simply a Martian EDL.  Anita provided much technical information on this subject and we learned that the actual EDL is driven by the entry mass and the need to dissipate energy. She talked about the difference in  a human EDL protocol and a robotic mission EDL protocol and said the human EDL has not yet been devised or worked out.  Near the end of the program, Anita explained more about laser cooling, including photons pushing atoms which slows them down and makes them cooler.  This enables more accurate laser tuning for the research. Susan asked her if she learned about the engineering for her project from grad school or from OJT.  As you will hear, the basics from grad school and the specifics OTJ.  Near the end of our program, we talked about the role of a project manager and auditing Anita’s USC class which might be possible when she teaches an upcoming graduate class online. We also talked about career choices and would one rather work on a humans to Mars flight or robotic missions.

Please post comments/questions on The Space Show blog above.  Dr. Sengupta provided her contact information on air at the end of the program or you can email her through me if you prefer.

We welcomed Dr. Bruce Damer back to the show to discuss his 3D real time simulations, the human NEO mission study & design project, planetary protection, astronaut safety and much more.  Here are the websites Bruce mentioned on air:  www.damer.com, www.levityzone.com, and www.digitalspace.com.  In addition, later in our discussion Bruce also talked about a Dave Brody YouTube video that was relevant to our discussion.  You can find this video at www.youtube.com/watch?v=UAm9escDxu0.   In the first segment of our 1 hour 31 minute discussion, Dr. Damer talked about the renewed interest in asteroid projects within NASA and by others, especially after the Russian event a few months ago.  Dr. Damer had lots to say about a recent meeting he attended at AMES, budgets, and the renewed interest in the subject.  Listeners started asking him questions early on, including questions about docking with an asteroid with little or no gravity, the use of aerogel to collect micrometeorite particles, plus the recently announced commercial asteroid missions being planned.  Robots versus humans came up many times, Curt asked about the use of the ISS, prioritizing budgets, lunar basis, etc.  Doug called in regarding the incremental approach Dr. Damer had mentioned or as referred to in our discussion, stepping stones.

In the second segment, we talked about the designs on www.digitalspace.com and the Brody YouTube video per the above URL.  Also discussed was planetary protection with the use of the gravity tractor. We talked about needed lead times to interfere with a potentially dangerous NEO that might be headed for Earth,  then more questions came in about a lunar base and what Bruce thought to be more important, the lunar base, Mars, or the NEO mission.  Doug called in to discuss and challenge some of the mission planning ideas Bruce put forth, especially around trial and error, R&D, incremental development and long time lines.  Near the end, we talked about human spaceflight safety & the ideas put forth by Rand Simberg & others that we needed to take more risks, not make safety the extreme priority.  Bruce had many relevant & important comments on this subject.  Final comments focused on 50-100 years in th future with asteroid & other capabilities but only if we keep moving forward today.

We welcomed Dave Ketchledge back to the program to discuss Mars precision human spaceflight lander choices.  During the first segment of our 2 hour 13 minute discussion, we covered Dave’s basic thesis and analysis regarding landing large payloads on Mars and the need for very accurate and precise landings for the human spacecraft.  While at times the first segment was technical and perhaps complicated, it provided the necessary groundwork and foundation for our discussion during the second half of the program. During the first part, Dave explained the need for a precision human landing on Mars, the difficulties in doing that, the pros and cons of the various shapes to use for the human spacecraft, and why the Pershing 2 missile nosecone offered the best shape and design.  Dave cited his references for his analysis and conclusions.

In the second segment, we started with a listener question about the origin of the DC-X vehicle design as it was related to the analysis, conclusions, and explanations Dave provided earlier in the discussion.  Dave continued his comparison and analysis of the three potential vehicle designs, then I asked a series of questions sent in by listener Curt from the recently held Humans to Mars conference regarding issues in landing a large payload on Mars.  Dave also spoke about heavy lift and the need for an SLS type vehicle, speaking to the additional needs for using smaller launches. These needs include planning on replacement launches and payloads which must be figured into the costs as all the advance launches of supplies & materials to Mars will be mission critical launches.  The crew should be the last launch to the planet. Listeners both emailed in questions for Dave and additional listener phone calls were received.  Dave continued to reference the NASA Mars Design Study, work done by JPL, Dr. Robert Manning, and others. We talked about the Mars One program & how it might land its human crew on Mars.  We also talked about HSF to Mars policy &the absence of political leadership for a human mission to Mars.  Dave addressed media issues but largely stayed with the shape of the human spaceflight spaceship, the need for a precision landing, and what might work best.

Please post your comments/questions on The Space Show blog above.  You can email Dave at the address he provided on air at the end of the show.

During our 11 minute plus discussion with Dr. Ed Stone & John Batchelor, we discussed the current status of the Voyager 1 and 2 spacecraft and their soon entry into interstellar space. Dr. Stone, who has been the Chief Scientist of the Voyager project since the beginning with the project development in 1972, then the launches in 1977, talked to us about the Voyager mission, the Golden Record onboard Voyager 1, the role of Dr. Sagan, and what it will mean when the spacecraft finally leaves the heliosphere and enters interstellar space.  We also talked about the rest of Voyager’s life after the power goes out for good around 2020.  When Voyager was launched in 1977, it was able to do a flyby of the giant gas planets in a special orbit that comes about once every 176 years.  This orbit also made it possible for Voyager to reach Neptune in just 12 years!  Also discussed were total Voyager 1 and 2 mission & development costs plus their annual operating costs which run around $5 million.
