We welcomed Dr. Jason Reimuller back to the show for this 1 hour 28 minute discussion and update regarding Project PoSSUM (www.projectpossum.org). During the first segment of the program, Dr. Reimuller provided us with an overview of Project PoSSUM, then he went into detail regarding the need to study the mesosphere and Noctilucent clouds. He explained his two training programs, the PoSSUM Scientist-Astronaut Qualification Program and the PoSSUM Academy. I found it interesting that both programs have a math level requirement for participants. Our first segment was devoted to Jason telling us about these two programs as well as their research projects which included a spacesuit research project along with Final Frontier Design. Near the end of the segment, we talked about launch vehicles to be used by Project PoSSUM, timelines & FAA licensing requirements.

In the second segment, Jason focused on their public and educational outreach programs for their science projects. Jason told us about their high altitude balloon projects, probably with World View and the global appeal of their citizen science projects. Among the many listener questions, Ronnie asked about the field of aerometry while another listener inquired as to why the study of the upper atmosphere was important. As the segment was ending, listeners asked Jason about his use of cubesats while another listener asked if balloons from JP Aerospace would be used. Also mentioned was the PoSSUM manual which can be obtained from the Project PoSSUM website along with various articles of spirit ware. Gina got the last question in to ask if one could get by in the two programs without the required math that Jason mentioned earlier in the show.

Please post your comments on TSS blog per the above URL. Jason can be reached through me or his website (he also gave out his email address on air).

We welcomed Dr. Dava Newman to the program to discuss her positive pressure BioSuit spacesuit project at MIT.  During our 1 hour 1 minute single segment program, Dr. Newman took us through a brief history of positive pressure spacesuits up to and including her BioSuit version 4 project. For more information, please visit these and other websites: http://web.mit.edu/aeroastro/www/people/dnewman/bio.html; www.bostonmagazine.com/news/blog/2013/12/10/mit-biosuit-system-dava-newman;   http://mvl.mit.edu/EVA/biosuit and http://esd.mit.edu/Faculty_Pages/newman/newman.htm. We covered many topics, fielded numerous listener email questions, and learned much about the BioSuit as well as traditional spacesuits.  The history started with Dr. Paul Webb and his efforts from the early 70’s (Dr. Webb was a guest on TSS on Sep.t. 17, 2006), then we talked about the progress in materials, designs, and engineering leading up to the BioSuit.  Dr. Newman explained how flexibility and movement were possible in the BioSuit, how this reduced the amount of energy expended by the astronaut, and even reduced some of the thermal needs.  We also talked about repairs of the suit, then we spent much time talking about the life support and EVA pack plus the helmet.  As we learned, joints and concave parts of the body like the back of the knee do present problems but they believe they have solutions to these challenges by using special materials to fill in the void spaces.  At one point, Professor Newman was asked about needing different suits for orbit, the Moon, and Mars.  As we learned, the basic suit is the same for everything but depending on the mission, different life support and EVA packs would be available.  Then we talked about a suit for inside the vehicle or the ISS, the Variable Vector Suit.  Questions came in about how the suit works, closes up, and suit economics compared to the costs of traditional spacesuits and EVA suits.  Questions about radiation protection, lunar dust protection and more was asked, plus we talked about the possibility of using the basic BioSuit for space tourism flights providing the tourist is not outside the spaceship.  During our discussion, Professor Newman went over many of the pressure issues and requirements plus other technical issues for this suit.  We also learned that it could be made operational within 2-3 years of full up funding.

We welcomed Michael Belfiore back to the show to discuss his recent XCOR Aerospace article (see www.airspacemag.com/space-exploration/The-Lynxs-Leap-223968551.html).  For more information, visit Michael’s website,  http://michaelbelfiore.com.  During the first segment of our 1 hour 44 minute program, Michael talked extensively about XCOR Aerospace and the Lynx per his above Air and Space Magazine article.  Michael has been a long time follower of XCOR and it shows in this discussion.  We also talked about the other suborbital companies and space tourism in general.  Michael was asked about XCOR’s plans to go orbital from suborbital which was another topic Michael had much to say about.  He said his preference was to fly on a Lynx for the more personal and intimate space experience, including wearing a space suit.  Michael said he was bullish about the overall space tourism industry, he is attracted to the growing small satellite industry but remains partial to human spaceflight.  We talked about SLS which he tends to ignore and discount, SpaceX and Orbital Sciences.  The topic of Cislunar space development came up and while Michael said he was supportive, he is drawn to asteroid economic development.  Before our segment ended, he updated us on the Google Lunar XPrize and I congratulated him for winning the NewSpace Journalism Award this year.

In the second segment, Michael was asked about DARPA which he follows. We talked about Starship 100, the DARPA management style & out of the box operations, the Dec. 20th robotic competition that Michael will attend, plus other important attributes of DARPA.  He mentioned upcoming magazine articles he will be writing for Popular Mechanics and AEON Magazine.  Michael was asked about other national space programs including China’s, Russia’s, and more. Doug called to talk about interstellar DARPA activities, and his cislunar economic ideas.  We also talked about returning to the Moon for settlement.

During our 11 minute plus discussion, John, Pablo de Leon and I talked about the recent spacesuit helmet to flood with water and the associated risk for Astronaut Luca Parmitano.  We also discussed design and technical flaws with the American EVA spacesuit as it was not designed to be maintained and serviced in space but to be brought back to Earth using the shuttle.  In contrast, the Russian Orlan suit was designed for repairs and maintenance in space.  Pablo mentioned other differences as well with the American and Russian suits. For example, the Russian suit operates at a much higher pressure causing the user to tire more easily and quicker, plus the higher pressure limits some movements.  I asked Pablo about progress with the idea of the positive pressure suit but as you will hear, nothing on the near term. In fact, as our Hotel Mars segment ended, Pablo said we will be using existing suit technology and materials for at least ten more years before new materials, manufacturing processes, and concepts are able to being entering the market.

http://archived.thespaceshow.com/shows/1798-BWB-2012-06-18.mp3

Guest:  Rick Searfoss (Col., USAF, RET.).  Topics: Rocket Flight, XCOR, Lynx, flight safety, leadership.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, https://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright.  We welcomed back to The Space Show Rick Searfoss to discuss spaceflight flying, XCOR Aerospace, the Lynx, and much more.  You can learn more about Rick Searfoss by visiting his website, www.astronautspeaker.com.  For more about the Lynx and XCOR, visit www.xcor.com.  We started our discussion with an overview of a successful test flight program.  During this discussion, our guest made it clear that flight tests are supposed to detect the unknown and to catch problems in time for them to be fixed prior to surfacing during commercial operations.  The test pilot is prepared for the unknown and this is why he later said that future XCOR pilots would need to have U.S. military test pilot school experience along with their military flight experience.  Also, the testing starts out very slow and escalates based on the progress and analysis of the tests.  One crawls before one runs, so to speak.  I asked him to compare a spaceship test flight program to information I had on a new Boeing 747-8 Intercontinental Jetliner that Boeing was putting through 600 flight hours of flight tests (www.examiner.com/article/new-boeing-747-8-intercontinental-maiden-flight).  Don’t miss this discussion, its interesting, important, & relevant.  Col. Searfoss received an email from Jeremy asking about humans riding on solid rocket boosters (SRB) and the safety in doing that.  This resulted in another interesting discussion.  We then talked about piston pump technology, suborbital flight, turbo pumps, and the XCOR program working with ULA regarding hydrogen pumps.  I asked Rick to describe the Lynx flight from the passenger perspective.  Doug wanted to know about the first flight timeline for later this year and then Christine wrote in asking if the Lynx cockpit would have dual controls similar to an airplane.  A question came in about the Chinese rendezvous & docking per their current mission & Rick’s take on the process given his space shuttle pilot experience.  Rick talked about this with the shuttle in some detail.

In our second segment, Terry called in to ask about the XCOR flight software.  As you will hear, XCOR flight software means humans.  Listen to what he had to say about this, including issues with space shuttle software.  Our guest then talked more about the flight readiness process including the Technical Review Board and Safety Review Board process.  Other topics discussed included citizen science on board the Lynx, ITAR issues, additional Lynx pilot qualifications, and defense dept. applications for Lynx and the suborbital industry.  Lee called in to ask about an evolution to an orbital vehicle, other questions came in regarding runway requirements, passenger height & weight requirements, and spaceports.  Near the end of our discussion, we talked about an emergency exit from the Lynx, spacesuits and bailout.  Also discussed throughout the program were suggestions for the passenger to better prepare for his/her flight.

Randa & Rod Milliron with Olav Zipser, Sunday, 5-13-12

http://archived.thespaceshow.com/shows/1773-BWB-2012-05-13.mp3

Guests:  Randa and Rod Milliron; Olav Zipser.  Topics:  Interorbital Systems update, Olav Zipser & freeflying rocket ejection.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, https://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed back Randa and Rod Milliron for updates with their company, Interorbital Systems (IOS).  Visit their website at http://interorbital.com.  During our first hour long segment, our guests provided us with a current overview of IOS, their rockets and their static and flight testing upcoming program.  We talked about their sea launch plans, their rocket fuel which is white fuming nitric acid with turpentine/furfuryl alcohol, and their TubeSat and newly added CubeSat personal satellite kits available on their website.  We learned more about their modular rocket plans along with both suborbital and orbital plans for the company.  Listeners asked lots of questions about their modular rocket system, ocean launch, their choice of fuel, and the high altitude jump from their rocket planned by Olav Zipser.  In the last segment of the program, Olav joined us for a detailed discussion about his plans so more about that later in this summary.  We talked about the personal satellite kits and I asked if they were user friendly in terms of building them. As we learned, they do require expertise and thus are a terrific learning tool for students as well as others, crossing over many disciplines from soldering to software programming.  If you or a group are interested in these kits, contact Randa/Rod for more information through their website.  Some listeners asked our guests technical questions about their guidance system plans and their rocket pressure fed system.

In the second segment, Olav Zipser joined us.  For more information about Olav and his freeflying astronaut program which he created, visit his website at www.freeflyastronaut.com.  His freeflying program which he invented for skydiving allows him to use his body as a type of “lifting body” (he cannot go up) in that he can change his positions, movements, angles, etc. to actually “fly” during his skydive.  For jumping from the IOS rocket at about 40 KM (25 miles), he intends to practice the jumps from various altitudes working up to his main jump altitude in which he hopes to break the record set by Air Force Captain Joe Kittinger decades ago.  Olav fielded several questions about how he intended to exit from the rocket, stabilize himself against spin, handle human supersonic flight including going into and out of supersonic flight.  Olav had much to say about the need for a custom designed space suit to allow him to safely do his jump.  He also explained why he was working with the Russians on this space suit design.  As you will hear, flexibility is crucial to the type of space suit he requires for this jump.  At the end of our discussion, Olav said that his suit design and what he learns from his jump should allow a safe emergency crew exit even for an unconscious person, giving the person a fighting chance for survival.  Our program ended with a brief summary of thoughts offered by Randa and Ron, their plans to attend the CubeSat workshop which is part of SmallSat each year, plus they left us with a worthy closing statement you will want to hear.

http://archived.thespaceshow.com/shows/1763-BWB-2012-04-29.mp3

Guest:  Dr. John Jurist.  Topics:  High altitude sky diving, space vehicle crew escape, free fall from space.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, https://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright. We welcomed Dr. John Jurist back to the program to discuss his latest research dealing with high altitude bail out, space vehicle crew escape, free fall from space, and more.  Dr. Jurist introduced us to the subject by talking about the history of experiments and research in the 50’s and the 60’s for high altitude bail out and the possibility of orbital speed crew escape.  He discussed many technical issues and jump/escape parameters so do listen carefully to our entire discussion.  Issues we addressed included aerodynamic stability, acceleration, deceleration, turbulence, spinning, heat dissipation, and the need to trust one’s equipment.  For example, he cited the famous Capt. Joe Kittinger jump as well as the latest effort to surpass the Kittinger jump by Red Bull and Felix Baumgartner.  Dr. Jurist discussed the differences in suborbital and orbital bailouts and we discussed the generic escape scenarios for upcoming suborbital flights.  John talked about the old Air Force Project Moose program and a listener asked about a free fall from orbital flight, perhaps from the ISS.  Dr. Jurist explained how this might happen and what would be needed for the person to deorbit, free fall, return to the atmosphere, and to survive the experience.  We also talked about the possibility of entering the atmosphere at too steep an angle and skipping off it with the potential of not ever returning.  He said this would not happen.  Don’t miss this fascinating discussion.

In our second segment, Carl asked Dr. Jurist to explain the SR-71 accident that he mentioned in the first segment. This is an amazing story.  You can read about the SR-71 incident described by Dr. Jurist at www.916-starfighter.de/SR-71_Waever.htm.  When asked for lessons learned, John said always trust your equipment and your training.  We talked about cabin pressurization in this segment and John got lots of questions comparing aircraft pressurization systems to those of a space vehicle.  This brought up the use of pressure suits, space suits, and possible shirt sleeve environments for space vehicles.  Later in this segment, John talked about spinoffs, specifically accident improvement with results showing up in the auto industry with safer cars.  Later, he was asked if he thought we were on the right track with HSF crew safety and escape issues and he said we were and that it was an evolutionary process.  Near the end of the program in response to a question, he said the most likely failures would take place in the boost phase of the flight.  Informed consent was mentioned as an issue to be aware of, then he concluded by saying that people are tough and can survive accidents and catastrophic events with the proper equipment and training.

Guest:  Doug Jones.   Topics:  XCOR Aerospace and the Lynx.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, https://thespaceshow.wordpress.com. Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright.  We welcomed Doug Jones to the program to update us on XCOR Aerospace, the Lynx suborbital vehicle, rocket engines, and more.  Doug is a co-founder of XCOR. You can find out more about the company at their website, www.xcor.com.  Doug started us off with a brief history of XCOR from the beginning to today.  After this historical overview, I brought up an email question from Andy in the UK about a scaled up version of the Lynx engine for a version of ULA’s Centaur upper space or space tug.  Doug had much to say about the ULA space tug idea in response to the listener question.  Doug then talked about the Lynx suborbital vehicle and the various versions of it, the Mark 1, Mark 2, and Mark 3.  He was asked if XCOR was planning to do anything with the newly announced Planetary Resources venture yet to be described. He did say there were ways XCOR could be supportive of some aspects of a deep space mission.  Doug addressed crew exit from the Lynx and described the seat lifter, using a parachute, and the exit strategy plus Lynx training before the flight.  Near the end of the first segment, Tony asked about Doug’s earlier comments regarding the nonburnite tank and Harry inquired about different pricing for the various Lynx vehicle versions.

We opened the second segment with a call from Jon in Jersey City regarding manufacturing and pricing targets with Space X as well as relating to XCOR.  Doug talked about production lines and more or less mass producing parts for the benefit of commodity pricing.  Bill from Virginia sent in a note asking about the relationship of test burn times to an operational flight with much longer burn times.  He wondered if short test burn times for the engines and systems was enough.  We also talked about the flight test program and backup vehicles.  Tony called in and wanted to know about the possibility of bringing back the Rotary Rocket engine.  Doug had some interesting comments on this issue.  The flight test program came up again and our guest provided us with a basic idea of how the test program would unfold.  ITAR was a big subject in this segment as were several listener questions dealing with piston and pressure pumps for XCOR engines.  Toward the end, we talked about spacesuits, 3D printers, vertical integration for manufacturing, and the Lynx serving as a space taxi vehicle, not a rental car.  This latter point was made when Doug was asked about independent operators buying and flying the Lynx as compared to XCOR flying and operating the Lynx.
