Welcome to this two hour one minute Open Lines discussion on what turned out to be mostly about artificial gravity. While there were actually two breaks in this program, since the topic was the same throughout the full show, I am archiving this as a single segment summary. We started the program by my making announcements, then reading parts of an article that recently appeared in the Turlock Journal (www.turlockjournal.com/section/26/article/23874) that talked about the green efforts by actor Leonardo DiCaprio but also pointing out his having arranged to be an early passenger onboard SpaceShip2. The author of the article, Dennis Wyatt, then pointed out the hypocracy of Mr. DiCaprio by examining the carbon footprint of SpaceShip2 & comparing it to cars & other things, pointing out the enormous consumption and carbon footprint that will be unloaded on Earth by Mr. DiCaprio's flight. I read parts of the article to point out the hypocracy among those that preach to us to do as they say yet they seldom if ever walk their own talk. I also mentioned articles in the informative menu of The Black Bear Diner Gazette from their Emeryville, CA menu, one of which was an old news article saying that NASA Administrator Thomas Paine predicted & had a goal of doing a HSF mission to Mars by 1981-82. Some of the callers for today's discussion did offer comments on both the DiCaprio article as well as wondering if we could have gone to and from Mars with astronauts back in 1981-82. However, by far, the topic of the day was artificial gravity, a topic which really surprised me. The callers and those sending emails wanted to talk about artificial gravity, their understanding of it, how to achieve it, their analysis of it, and more. The callers talked 2 RMs, 3 RPMs, 4 RPMs, we talked about some of the comments by the life scientists on this subject on previous shows, much of which was discarded by the callers who had a focus on engineering and physics and their own perspectives. We also talked about the difference between partial gravity & full 1 g artificial gravity. I mentioned that many were unsure that 1 g of artificial gravity would be the same as 1 g here on Earth but that was quickly discarded by all callers and those sending in emails. Our callers also talked about experiments that should take place using free flyers adjacent to the ISS to study some of the artificial gravity questions in preparation for long duration human spaceflight. Because of the unexpected interest in artificial gravity, I have decided to arrange for updated programming on the subject with "experts" representing aerospace medicine, life scientists, engineers that would be designing space based centrifuges, and more. I will be announcing these programs as they are scheduled & they will appear in the weekly newsletters. Please post your comments/questions for this show on TSS blog above.
