In the first segment of this 2 hour 2 minute program, I put forth some suggested topics and once again, I explained phone line issues for listeners regarding land lines, VoIP, compression, cordless phones, cell phones, digital phones, and even fiber lines. Phone line issues remain the number one problem faced by The Space Show in delivering quality audio so once again I went over the requirements and the restraints based on our equipment and broadcasting equipment in general. Several listeners did comment on the phone line issues via email. John from Florida was the first caller and he talked about Ernst Stuhlinger and his work plus he requested Dr. Jeff Hoffman of MIT return as a guest to the show. During our conversation, I mentioned ULA CEO Tory Bruno recent & his lecture at Stanford on the pros and cons of rocket reusability (www.youtube.com/watch?v=9DMb2yHh5CA). Marshall was the next caller who talked about cell phones and the DSP computer in the phone. He also talked about SOHO and replacing old satellites with new ones. We talked about the cost of doing that and Marshall said he would gladly pay 5% more in taxes if he was guaranteed the money would be used for satellite replacement. I asked other callers if they would do that but nobody bothered to respond. Marshall said we needed a satellite replacement program so jokingly, I suggested a Cash For Old Clunker Satellites modeled after the Cash for Clunkers car program several years ago. Michael Listner called to talk about recent news articles suggesting the FAA was going to regulate lunar business. He clarified this for us. Emmet sent us a note suggesting Doug had a video on the net which had gone viral thus making Doug an internet star (www.youtube.com/watch?v=Rzy63276GEg). In the second segment, Doug called the show & explained the video as a product of www.moonandback.com. Doug talked about the planned SpaceX launch later in the day, the recovery of the first stage and the Falcon Heavy as part of his overall heavy lift discussion. He also raised some questions about the Dawn Mission and its potential findings regarding Ceres. Turbo pumps came up as did other issues with liquid rocket motors such as which fuel to use given my promoting the late April webinar addressing these and other rocket issues. Ken from Dallas called to talk about Moon Day set for July 18, STEM, and he also mentioned Asteroid Day set for June 30. As Ken is a sci fi movie authority, we talked some movies and TV shows. John from Ft. Worth called and mentioned a movie and the satellite being launched by SpaceX nicknamed the Al Gore Satellite for Climate Change. John briefly mentioned The Telegraph article showing how temperature data had been tampered with and calling it the biggest scandal ever (www.telegraph.co.uk/news/earth/environment/globalwarming/11395516/The-fi...). John put forth some growth and population statistics as part of his argument against global warming. Other subjects mentioned during this open lines by listener emails included why there was no live streaming of the first stage recovery attempt for the Falcon 9, why drones were not suitable for live streaming as they were with the Orion flight, plus many listeners emailed in about Cash for Clunkers & old satellites and the projects and work of Ernst Stuhlinger. Please post your comments/questions on TSS blog above. You can reach any of the callers or those sending email through me.
