Remember that if you order this book through Amazon to use the OGLF Amazon portal so Amazon will make a contribution to TSS. Instructions are on both The Space Show and our blog's websites.

During the first segment of our 91 minute program, Louise told us about new developments and her work since her first Space Show appearance on Oct. 27, 2008. She told her about her science work and related travels at JSC and her work with the moon rocks. She also explained how her work with the moon rocks was important to human spaceflight, especially a return lunar mission and an asteroid mission. She talked about why a lunar return mission was so important for science & why it was better to have astronauts on the mission rather than only robotic. Out of this discussion came another SLS discussion as Louise pointed out the need for heavy lift for a lunar or any BLEO mission. I explored her thoughts and opinions on SLS, asking her about the perspectives provided by those not supporting SLS. In my opinion, Louise put forth excellent arguments in support of SLS during the show. I even suggested she become the spokesperson for SLS and lunar return missions given how well she articulated and explained the need for SLS. Louise also spoke about the distance from Earth to the Moon and the lunar orbit, referencing the LLRE (The Lunar Laser Ranging Experiment) from the Apollo era. She used information from this device in comparison with three other measuring methods to support her theory that the speed of light is slowing down. Listen to her explanation behind her theory assumptions. Louise then mentioned the very accurate atomic clock soon to go up to the ISS, ACES (see www.esa.int/Our_Activities/Human_Spaceflight/Human_Spaceflight_Research/...). She said this would be very helpful in detecting and clarifying the change in the speed of light. John from Ft. Worth called with several questions and comments about the speed of light. Next, Paul asked a series of email questions about time travel. In the second segment, we started off discussing time travel and speed of light changes for a multi-generational human mission. Louise introduced us to time dilation. John in Montana asked about GPS timing & the change in the speed of light. Christine emailed a question about an RTM mission and asked what might change if the speed of light is slowing down. Next, we talked about Planck units and the equation GM=TC^3 which is the same as M=R=t. Peer review was discussed as were the challenges of getting new theories introduced into the literature. As you will hear, old ideas do not go lightly into the dark, so to speak. Louise then talked about having discovered a lunar orbit anomaly and referenced her paper, "Calculating a Lunar Orbit Anomaly" which you can download at www.lpi.usra.edu/meetings/lpsc2013/pdf/2436.pdf. As the program neared its end, I asked our guest about her idea that there might be a mini black hole in our sun. Louise told us about her theory & talked in general about mini black holes. Our last subject dealt with her interest in positive pressure suits for IVA purposes. If you have comments/questions, please post them on TSS blog. You can reach Louise through her blog or me.
