We welcomed Dr. Pamela “Rai” Menges to the show. I suggest you visit her websites and follow along as applicable with our discussion. Visit http://arsispace.com/spacetechnology.htm and http://starsailorenergy.com. During the first segment of our 1 hour 47 minute show, Dr. Menges introduced us to Aerospace Research Systems, Inc. (ARSI) and talked about the company history dating back to its founding in 1993. We talked about research technologies, private R&D, government funding for research, and specific projects referenced by our guest including the Space Power Laboratory. At one point Dr. Menges discussed the pros and cons of taking government research money and why she elected not to do so. Also, the use of public relations (PR) and the role it plays with those accepting government money. After a brief mention and discussion of the possible space policy positions presented by Ohio Senator Rob Portman, we turned our attention toward power storage and the work our guest has been doing in this area for non-electrolytic power storage. Don’t miss this discussion. Another topic was the use of AC and DC power transmission, the Carrington Event in the 1800’s, and our electrical grid. Jack emailed about the spaceplane shown on the ARSI website, the Ramstar Model. Our guest had much to say about this experimental spaceplane concept and design. I

n the second segment, Ben in Boston asked about telemedicine commercial astronaut healthcare per the descriptive on the ARSI website. Pamela went into detail about this topic, their work with JSC and more. We then spoke to the issue of commercial astronaut safety in general with our guest expressing her thoughts of the safety issues within the industry and the regulatory environment. Later in the segment, the concept of ground effect vehicles came up along with advanced hypersonic technology and even SSTO possibilities. I asked our guest about nuclear propulsion and then several listeners asked her about it as well. Carol’s email took us on a different path as she asked about the need for lots of centrifuges for a peaceful nuclear energy program. This opened the door for our guest to speak about nuclear weapons, the current talks with Iran, and the treaty organizations that safeguard against proliferation. Pamela had much to say about this subject, our government, the Iranians, enrichment, centrifuges, trust but verify and more. Do not miss this discussion. Ft. Worth John called to ask about the use of centrifuges as opposed to other technologies such as gaseous diffusion. Near the end of the program, Luis emailed us about Reaction Engines and the Skylon project space plane. He too sent in a question about winged ground effect vehicles. Kristopher emailed us to check out “Caspian sea monster” on YouTube for an example of these vehicles. Dr. Menges talked about her new book that will be out in the near future and for Pearls of Wisdom suggested “doing what you want to do to pursue your dreams.”

Steve Bouley, Wednesday, 1-18-12


Guest:  Steve Bouley.  Topics:  Wideband Global SATCOM launch, Pratt & Whitney Rocketdyne engines, hypersonics, commercial space markets & more.  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 Steve Bouley of Pratt & Whitney Rocketdyne (PWR) to discuss the Delta IV medium launch of the DOD Wideband Global SATCOM (WGS) communication satellite, hypersonics, lowing the cost of access to space, rocket safety and more.  We started our discussion with a focus on the Jan. 19th 7:38 PM EST launch of WGS on the Delta IV medium which uses PWR RS-68 and RL10B-2 engines.  Mr. Bouley provided us with thrust specs for the engines.  He also went over the very impressive and highly successful track record for their engines and fielded questions about their manufacturing and quality control process.  This took us to our next subject, equating reliability with experience and then understanding that the launch market is relatively flat with low launch rates which causes higher launch prices.  There were several listener questions during this special one hour interview.  The questions focused on human rating the rockets and what PWR would have to do to their engines to have them fly people to space.  Don’t miss Steve’s response to this line of questioning.  We talked some more about the flat demand and Steve was asked if PWR could easily and quickly ramp up their production line were demand to change quickly.  The short answer was “yes.”  We talked about hypersonics and the evolution of technology development.  We also talked about the likely path to commercial operation for a hypersonic vehicle.  Our guest took a call from Jerry about SLS, SRBs, the Saturn V, and bringing back the F1A engine.  Mike sent in a note asking about safety issues for a jet engine as compared to a rocket engine.  Toward the end, our guest was asked to provide the very early history of PWR and rocket engine development.  As our program drew to a close, I asked Steve to tell us about his work on launch day and if he still gets excited about a launch given he has seen hundreds of them during his career.  Post your comments/questions on The Space Show blog URL above.
