During the first segment of our 1 hour 56 minute discussion, Bob started out with an historical overview of the progress made in developing the commercial space industry, a U.S. cargo capability to the ISS, and eventually the U.S. capability of carrying astronauts back to the ISS. He started his timeline in 2004, specifically addressing the time since President Obama came to office. For almost the entire first segment, Bob noted milestones, progress, company developments, the beginning of competition and much more. Later in the segment, he mentioned what he said was the lack of progress in the suborbital industry during the time period he had been talking about and suggested that the suborbital companies may be missing parts of the market given their continued delays. He talked about this in more detail during the second segment. He also talked about human spaceflight (HSF), SLS, Falcon and SpaceX as a game changer, the efforts of Sierra-Nevada to continue on with Dream Chaser, & his opinion that it will likely be the private sector that manages HSF to the Moon and Mars rather than a public program. We talked about public opinion and space, then Marshall called to ask questions about China, their space program, plus a possible Chinese impact on our space policy. Bob had much to say about the Chinese program, then he had about an equal amount to say about the Russian program. Sylvester emailed in to also ask about China, specifically if Bob thought we would soon be cooperating with one another in space. Bob seized this opportunity to make it very clear as to why he disliked international partnerships, instead preferring competition. Before the segment ended, Beth asked Bob for his thoughts on the Moon-Mars debate. In the second segment, Kristen started us off talking about LightSail. Bob had much to say about the mission, The Planetary Society, how it was funded, and the fact that it was based around using cubesats. He then spoke to the success of cubesats and how they are changing aspects of the industry. Bob jumped to Comet 67 P, the Rosetta mission and the Philae Lander. He used this opportunity to provide an overview of planetary missions starting in 1957. In talking about the success of planetary missions, he mentioned the Dawn mission to Ceres and Vesta plus many more. I asked Bob about New Horizons and Pluto. Bob had much to say about Pluto, its moons, & specifically the moon Charon. Other topics that came up as we neared the close of the show included the Europa mission and an effort to use crowd funding to make a porno film in space. This prompted Bob to say a few words about sex in space, plus he thought the porno film was just a PR stunt. Before the show ended, Tim in Huntsville asked for Bob to share his thoughts on the company Interorbital Systems. Bob then turned to the suborbitals having some things to say about Virgin Galactic, Blue Origins, and XCOR. He spoke to the need for redundancy, mentioned possible Stratolaunch problems with Orbital ATK no longer working with them on the rocket, then suggested some things to watch for in the second half of this year and closed out with a summary of key points he made during this program.
