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!”

Guest: Dr. Roger Launius. Topics: National Air & Space Museum at the Smithsonian, Mars in our culture, Russian & U.S. Mars missions. 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. The Space Show/OGLF is now engaged in its annual fundraising drive. Please see & act upon our appeal at https://thespaceshow.wordpress.com/2011/11/21/space-show-2011-fundraising-campaign. We welcomed back Dr. Roger Launius to the program. His blog which we talked about during the interview can be seen at http://launiusr.wordpress.com. We started our discussion with the mention of his recent blog post, “The Lure of the Red Planet: Early Flyby Missions to Mars.” Dr. Launius went through a short history of Soviet/Russian attempts to go to Mars as well as those of the U.S. in recent years. His blog article contains a more comprehensive listing of these missions and is a good resource for this information. We talked about private enterprise doing Mars missions and our guest said the business case would have to close for that to happen and that we were not there yet. I asked about cultural drivers concerning our interest in Mars. I also inquired about the symphony by Gustav Holtz, “The Planets” and his “Mars, Bringer of War.” Dr. Launius talked about Mars in our culture going back to H.G. Wells, others in the early 1900’s, science fiction literature, as well as early astronomy. Another of his blog posts we explored was his comparison of Sputnik to 9/11 as there were parallels and similarities. Don’t miss this interesting discussion. In our second segment, we talked about the Smithsonian getting the Discovery Space Shuttle, its eventual display, and the disposition of Enterprise which is currently at the Smithsonian. Dr. Launius explained how they will display Discovery to preserve it as close to a real time flying shuttle as possible for historical purposes. We learned that visitors will not be able to walk through it. He does explain the display plans in full, plus he talks about getting the shuttle from KSC to the museum near Dulles Airport and then getting Enterprise to New York as it is to be displayed at the Intrepid Museum. Roger received listener questions about the display of the Enola Gay B-29 which is at the Smithsonian as well as SpaceShipOne. Listeners also asked for his thoughts on Phobos-Grunt and its loss. Our guest pointed out it was the 5th loss of a Russian mission in a year, pointing to some definite problems in the Russian space industry. Some of the problems he described regarding the Russian space industry sounded similar to what is happening with our own space workforce. Commercial space and the private sector came up for discussion with Roger saying that a big difference is that private enterprise will operate their vehicles, not the government. Dr. Launius was asked about space tourism and if it was possible to evaluate any type of market based on visits and comments to the SpaceShipOne exhibit. We talked about STEM educational issues, protecting the Apollo lunar landing sites as historical sites, Pluto in the Smithsonian & the New Horizons Mission. As our program ended, we talked about Plutonium 238 and RTGs for space missions., And a listener wanted to know about the plausibility of one way manned Mars missions.
