We welcomed Jim Muncy back to the show for this comprehensive space policy and commercial space two hour plus discussion. While many topics overlapped both segments and we went back and forth on several topics, this summary will be a two part summary. Jim started the discussion with a look at new space legislation kicking off the year. After a short summary of several items and their impact on commercial space, we talked about the makeup of the new Congress and how it might view civil and commercial space. Jim then started addressing specific projects including Orion and its expansion to include ESA, SLS, the Boeing CST100, Atlas 5, and more. A listener asked about the Space Settlement Act and the Space Foundation Pioneering White Paper. We then turned our attention to Cis-lunar space as a commercial gateway and Jim mentioned new commercial opportunities such as Golden Spike. We also talked about the recent study on NASA by the National Academies. Other topics included the need to do exploration, to take risks and NASA acting more like the old NACA with aviation. The James Webb Space Telescope (JWST) was brought up by a caller and we started talking about large program expenses as compared to smaller, less costly, & more frequent programs that fly much more often. In response to another listener, Jim said SLS was not in competition for funds with commercial crew as one was near term & the other long term. Falcon Heavy was brought up, especially as an alternative to SLS.
In our second segment, Jim was asked about how best to influence congress. Later on, Jim was asked to comment on the liability indemnification issue surrounding Spaceport America & Virgin Galactic. Our domestic economic situation came up many times in both segments but in this segment, it was applied to problems with our weather satellite system & infrastructure needs as opposed to flying missions. This included mention of the Hurricane Sandy relief package just passed by Congress. Other issues talked about included the aerospace skilled workforce, parochial congressional interests, the NASA bureaucracy, & the role of space advocacy.

We welcomed Dan Adamo back to the program and Dr. John Jurist as co-host for this special webinar addressing trajectory analysis for an EML2 mission and more. On The Space Show blog, you will find Dan’s PDF document used during the webinar, a link to the movie he played in the second half of the webinar, and his Phobos-Grunt analysis paper we discussed near the end of the webinar. During the first hour of the webinar, Dan took us through the trajectory analysis to Earth-Moon L2 per his PDF document. We talked about why EML2, libration points in general, and how such missions are planned. If the resolution on the webinar video for the charts and tables used during this segment are difficult to read on your computer, please bring the document up on the PDF on The Space Show blog and follow along that way. Dan took us through Table 1, HALO orbits, and the HOI as well as the Trans-Lunar Insertion points. We talked about orbital characteristics, delta V, rocket size, and more We also talked about the position of the Earth, launch windows, the Moon, & other factors influencing the planning of the mission. While at times the discussion may seem a bit technical or overwhelming for those of us having never done mission planning at this level before, all of us will certainly have a better understanding of the factors considered and influencing both robotic as well as human spaceflight missions. Near the end of the segment, we talked about the SLS and heavy lift & how payload capacity interacts with mission & trajectory analysis.
In the second hour of our webinar, Dan took us through his HD movie of the orbital trajectory talked about during the first segment, stopping it at intervals for specific explanations and questions. The movie is in the QuickTime format but you can see it both on the webinar or by using the URL provided on the blog. We took several listener calls & questions. One asked Dan about the differences in planning for the robotic vs. the HSF mission using MSL & Curiosity as an example. Dan pointed us to a YouTube video he made a few years ago with Dr. Logan using these tools for a Deimos mission (
www.youtube.com/watch?v=X10GAqA4Ky4). Another listener called wanting to know the likelihood of an EML2 mission actually happening. Dan explained why he believed this mission to be the next stepping stone in HSF. More was discussed about SLS with Dan raising some concerns about its real capabilities & wondering if Congress is being sold unrealistic expectations. We talked about heavy lift in general & with the support of properly placed depots. SLS and the difference with a Falcon Heavy were also discussed in terms of what the differences would mean in payload, number of launches, costs, risks, etc.

Guest: Jim Muncy. Topics: Space policy, COTS, SpaceX, Commercial Crew and more. You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, http://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 Jim Muncy to discuss space policy in light of the very successful COTS flight by SpaceX with their Falcon 9 rocket and the Dragon capsule. During our fist segment, we talked about this COTS flight, the berthing with the ISS and what this might mean for the COTS program, space policy and funding issues, and commercial crew. Jim had much to say covering many aspects of our policy and budget concerns, plus NASA policy now and what we hope for in the future. We talked about challenges ahead, members of congress, resistance points, and human safety. Toward the end of the first segment, we asked Jim about the confidence level in the mission before and during it and if either Jim or others were surprised by the outcome. This is an interesting discussion, don’t miss it. As our segment ended, we were addressing HSF safety issues, NASA oversight and contracting methods.
In our second segment, we talked about ULA and human rating the Atlas and Delta rockets. We then discussed using the successful COTS model being used to move commercial crew forward. We again discussed down selecting as a possible result of congressional funding action/policy as opposed to the process currently in place that will eventually allow NASA to pick the program from all the contenders – the one NASA thinks may be best. Markets for HSF beyond the life of the ISS were discussed in detail and we had more to say on crew safety on the HSF rockets under development. Another issue talked about was the public option for launch vehicles that some policy people support and how to be an advocate with the most impact on our members of congress regarding space issues. I asked about the impact on space policy & programs given our national and global economic issues. In short, don’t expect more funding for NASA & space which leads us to now more than ever having alternative means of financing space missions. Commercial space programs & partnerships clearly provide an important & needed alternative. Toward the end, a caller brought up the Romney Space Advisory Committee. Jim suggested that things will change & not to assume anything as final at this point in time. He hoped that we had a good national debate in the coming campaign as to just what our space policy should be for the future.
