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. Please post your comments/questions on The Space Show blog. You can contact either guest through me.
