We welcomed to the show Dr. Jens Biele of the DLR to discuss the Philae Lander as part of the Rosetta Mission to Comet 67P. During the first segment of our 1 hour 27 minute discussion, Dr. Biele summarized the Rosetta mission going back to its planning and development days, the flight to Comet 67PM and the Philae Lander’s anchor landing failure which he talked about at length. He also talked about communications from the lander to the orbiter and the narrow window for successful communications. We talked about solar and battery power, the type of data it can still transmit and related issues. Later, he was asked about other forms of propulsion including ion thrusters and advanced propulsion, plus he was asked if it would have been better to power the spacecraft by an RTG. He summarized some of the trades involved in making these types of decisions so don’t miss the discussion. BJohn asked about other DLR missions so MASCOT was discussed and later he discussed AIDA and AIM. As part of this discussion flyby missions were detailed and trojan asteroids were discussed. The subject of searching for life came up along with the discovery of organic molecules. Near the end of the segment, Roger from Rutgers asked if they considered Philae a success. Don’t miss his answer to this one. Other topics in this segment including drill samples, mission operating cost considerations, launcher choices and the shape of 67P which was a puzzle yet to be explained.

In the second segment, I asked our guest about the extremely long mission planning and design times coupled with the very long flight time and how that impacted people wanting to work space projects. As you will hear, it is not much different in Europe than here in the States with the same issues with NASA missions here. BJohn asked additional questions about future DLR missions and robotic exploration. This is the discussion that talked about both the AIDA and AIM European missions. Listener Helen asked about general European public support of ESA and space. You might be surprised by what our guest had to say in response to Helen so don’t miss it. In this context, Dr. Biele talked about ESA PR and its limitations and constraints. Toward the end of our program, he talked about human spaceflight, referenced Mars and going to Phobos as an initial part of human Mars exploration. When I asked our guest for closing comments, he said “If you dare you win. Take Some risks.” His final comments were ” Landers are cool!”

Welcome to this 2 hour 11 minute Open Lines Show.  As we started our first segment, I made several announcements including the return to action for the Space Cynics blog.  This time we will be accepting guest editorials.  Watch for the guidelines/rules for guest editors and those submitting comments to the blog.  Once you see the guidelines/rules on the top blog menu bar, Space Cynics will be officially back. See http://spacecynic.wordpress.com.  I also talked about a recent NPR interview with the inventor of the Super Soaker water gun who just happens to be a top guy at JPL!  I’ll make an effort to invite this person to the show.  Our first caller was from Scott who wanted to talk about and promote his Droid platform app for orbital speed calculations.  If you are interested in downloading this app to your Droid device, search in Google Play for “Orbital Speed.”   Scott described his app and how it worked and since there was some history re the app and the Charles Pooley Microlaunchers book, that came up during the discussion.  This was probably the dominant topic in the first segment.  Pooley did call in regarding the app and the references to his book, but Charles, in addition to promoting Microlaunchers as he usually does, also spoke about himself as the SPACE Heretic.  You can read about this at the tiny URL goo.gl/vo7Ux7 (cut & paste to your browser or use the full URL http://www.linkedin.com/today/post/article/20140620023828-9942227-charles-pooley-heratic?_mSplash=1).  During this segment, we also talked briefly about hybrid rocket motors and specifically about escape velocity.  I read an email from B John in Sweden suggesting that going to the Moon or Mars was and is counterproductive for our HSF program.  I asked for listener comment but unfortunately this topic was not picked up by the listeners.  Perhaps some of you listening on archives will post a blog comment about B John’s ideas.

In the second segment, John Hunt called in to talk some more about escape velocity and the formulas for it.  He then asked a series of question about science and STEM education.  I shared what I knew about the topic but we were hoping for teachers or others involved in this field to call in with more information.  Perhaps those of you working in these fields can post some detailed comments in response to John’s questions on the blog.  We had several emails about American public participation for a better HSF policy and for influencing policy makers and Congress for space policy.  The email questions seemed to think some level of American public participation was needed but that the pressure in numbers was not there compared to non-space issues receiving funding.  Also, most thought that the next election was actually the focus of Congress so without the numbers and pressure pushing for this or that policy, other projects get priority funding.  John called back to talk about the need for competition and the lack of it.  Near the end, I read a series of emails with a space advocate saying those that disagreed with him on specific issues were wrong, uninformed, etc. I asked listeners what they thought of this my way or the highway space advocacy mindset.  John did talk about the upcoming NASA down select process and we both thought for sure SpaceX would be selected.  John then said NASA and the public program lacked vision but SpaceX had a vision.

Post your comments/questions on TSS blog per the above URL.  If you want to reach any of the callers, send your note to me and I will forward it to the person of your choice.

We welcomed Dr. Zubrin back to the show for this 90 minute discussion about everything Mars and the Mars Society.  Dr. Zubrin opened up by telling us about the Mars Artic 365 program (http://ma365.marssociety.org) and their fund raising efforts through Indiegogo and other programs (www.indiegogo.com/projects/ma365-a-one-year-mars-simulation-in-the-canadian-arctic).  Throughout the entire program, Dr. Zubrin received questions/comments about Arctic 365.  He was asked about telepresence and having the sim in a more populated place than the arctic.  Bob dismissed telepresence as not being nearly as effective as having humans work “on Mars” & he stressed the importance of simulating a real Mars working mission.  Bob went over the logistics and scheduling for this first crew for Arctic 365, plus remaining opportunities and ways for people to participate in the program as the crew selection process is closed.  We talked about the costs and crew skill sets, plus Mars Society fund raising efforts for this program.  Jack emailed about radiation on Mars and as before, Bob suggested it was not as big a risk as many claim.  He was also asked about teaming up with Mars One on Arctic 365 program.  Bob said he was open to doing things with Mars One and suggested Arctic 365 would be a perfect training program those who train the Mars One crews.  Later, Bob was asked about doing a completely private mission to Mars.  Bob used this as a spring board to describing the kind of policy & political leadership in government and NASA, both of which he said absent for now.  He even proposed some broad based financing suggestions.  Doug called wanting to know his thoughts on Phobos & Deimos.  Bob used this as an opportunity to support a flyby mission. He was not that supportive of visiting the Marian moons.  Don’t miss his explanation for his position.  As the segment was ending, I asked him about life on Mars.  Bob thinks there probably is life on Mars, don’t miss what he had to say about this.

In the second segment, Steve asked Bob about the Delta V needed for going to the Moon as compared to Mars.  He talked about the Moon being easier than Mars.  Again, don’t miss all of Bob’s response to Steve’s question/comment.  NASA and political leadership were more fully discussed in this segment, then he was asked about the SLS. Here, Bob had a lot to say. While critical of SLS, he would not cancel it.  Again, don’t miss his comments on this topic.  He talked about SpaceX & Falcon 9, heavy lift in general, crew size on a Mars mission, and finally possible threats from the Chinese space program.  Toward the end he talked about electric propulsion for slow cargo missions, then I asked him for his thoughts on the Mars cycler system.

Please post your comments/questions on TSS blog.  You can email Dr. Zubrin through me.

We welcomed Dr. Haym Benaroya, mechanical and aerospace engineer at Rutgers University, back to the show to discuss lunar thermal and seismic analysis, space policy, human spaceflight, Mars, and more.  Our intention was to do a one hour program but due to incoming listener phone calls, this program lasted for 1 hour 39 minutes without a break!  In addition, the discussion at times with callers was quite heated, very passionate and ripe with disagreement, especially between callers and myself.  Frankly, there were times I just had enough of the gloom and doom and the la la land fantasy stuff so I blasted back on what the callers more than the guest were saying.  We started the program with an update from Dr. Benaroya on thermal and seismic analysis of lunar data collected from sensors left on the Moon by the Apollo missions.  The data has been run through new models for up to date processing.  As it turns out, for seismic activity, an igloo like structure which Dr. Benaroya described is probably the best for the habitat. Also, he said only flimsy items such as an antenna would like be risky structures due to lunar seismic activity.  I asked him to compare lunar seismic activity to the seismic activity of California and Japan.  We have it much worse here on Earth!  We talked about radiation issues & Haym suggested about 10 feet of regolith on the top of the hab would probably be OK other than for a solar event.  He also said much more data was needed for actual lunar structural engineering.  I asked him what the first lunar settlers would do during their day and this took us to HSF to Mars issues, microgravity concerns, and the Moon as a stepping stone to Mars.  John Hunt was the first of the callers, focusing on policy with the politicians.  Haym talked 3D printing with him, then I asked John if the program he was describing could be done in 10 years.  After forcing him to provide us with a yes no answer, he said no. Haym said the same but both agreed technology was not the problem, leadership was the problem.  We talked the need for profits for private ventures and opened up public/private partnerships for discussion on the show.  I asked both how to start implementing their plans & that was the opening salvo of the fireworks that unfolded for the rest of the show.  Doug called next and talked about his ideas for what astronauts on the Moon would do and his lunar development ideas.  I then challenged both caller and guest to outline their steps for making their happen.  I thought their implementation plans were severely lacking and opened up on each of them but more so on Doug for the balance of his call.  Haym said the first step was to rebuild U.S. launch capabilities. Doug had a different first step & talked about government funding as in a private/public partnership similar to what SpaceX has with NASA for Falcon.  I asked Dough how he intended to sell the importance & value of the program he suggested to those controlling policy and funding.  See what you think of this discussion & post your comments on our blog.  After Doug cleared the line, Charles Pooley called in & at one time I said he was the longest playing broken record in Space Show history! I told him he was full of doom and gloom and other people see things differently and I did not want is view of things to be right or prevail, suggesting others see things differently than he does. Again, your comments are welcome.  Near the end, I simply was rejecting the “dismal situation” facing our space program. While Haym agreed that things were not good today, he talked about how he inspires and works with his students so they can create a positive space environment during their careers and for our future.  Just before the show ended, Tim called at the last minute and I promised to send him a Timex given his rotten sense of timing show after show. With Tim, we talked propulsion, Zubrin’s thoughts on going to the Moon, & the two private Mars missions on the drawing board.  In his concluding remarks, Haym explained why he was not supportive of either Inspiration Mars or Mars One.

Please post your comments/questions on The Space Show blog. Haym can be emailed through me or his Rutgers website.

Guest:  Robert (Bob) Sackheim.  Topics:  Commercial space, propulsion, U.S. space policy & more. 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 Robert Sackheim to the program to discuss NASA, commercial space, the current state of rocket propulsion and advancements in the field.  During our first segment of this 1 hour 47 minute discussion, Mr. Sackheim talked about his background and experience at TRW, NASA MSFC, and his current consulting.  I asked him several questions about the current state of rocket propulsion. Bob had much to say about this, focusing on chemical rocket propulsion, satellite propulsion, electric propulsion, and the need for nuclear propulsion.  He talked about booster rockets, various rocket stages and their propulsion, rocket engines, and even SRBs.  Several questions came in asking him if we had the current technology for HSF to Mars or even the Inspiration Mars flyby mission talked about so much in the recent press.  Listeners wanted to know if our current levels of propulsion were up to the task.  After a rather thorough propulsion discussions, Bob turned to commercial space, lowering total space mission costs, regulatory policy, and commercial spaceports.  He also talked about budget issues and raised the question a few times as to why ten NASA centers were needed given their often overlapping, competitive, and duplicate work.

In our second segment, commercial space took the lead with a discussion on public/private partnerships & the belief that Americans can do anything if we set our mind to it, including space travel.  Of course here the problem as we know lies in leadership and today it appears that leadership in space & other areas is sparse at best.   Bob then focused on geo satellites and the increasing development and capabilities applicable to cubesats.  HSF came up for discussion as did the robotic missions. You might be surprised by what our guest had to say about HSF.  Other issues in this segment included the lunar space elevator, the congressional and NASA track record in canceling ongoing projects & taking lessons from history, SSP, & ways to reform & move NASA forward.  Bob spoke about evolving toward the old NACA model.  I asked about the impact of space advocacy from his perspective given his leadership experience and past positions in leading organizations and projects.  We also asked him about space tourism and hybrid rocket engines. He had much to say about hybrids, don’t miss the discussion.  Bob talked about the Falcon rockets, testing including static fire tests, and SRBs as related to the Constellation project and safety.  Toward the end, our guest was asked about NewSpace, fuel depots, & cryo transfer.  For closing comments, he talked about commercial space being the way to go & the path to our space future.
