We welcomed back Dr. Jeff Bell & was at his best for blunt talk, specifically the need for a winning rational for human spaceflight (HSF).  For those of you new to Dr. Bell, hold on tight for a ride that will likely be upsetting.  During the first segment of our 1 hour 58 minute program, Dr. Bell started with saying he was pessimistic over the future of human spaceflight.  In fact, this was an overriding theme throughout the full discussion.  He said it was more than just not properly telling the story either by NASA or space advocates.  He said there was no winning rational for the need or the urgency of HSF.  While he was pessimistic on HSF, he was just the opposite on science, robotic, & unmanned missions which he said were doing well & in a class of their own.  He also talked about the success of satellites & that part of the commercial industry.  Listeners challenged him during the show.  He got several emails regarding space settlement which Jeff addressed in terms of his perspective on HSF.  He also nixed the idea of leaving Earth as a safety valve for when Earth might be destroyed by an incoming NEO.  This led Jeff to talk about planetary defense.  Tony called with an idea to keep a Martian settlement from freezing at night, a point Jeff talked about re Mars settlements.  A listener asked about radiation & magnetic fields.  Jeff said the atmosphere was more of a screen for Earth, again in a discussion about lunar & Martian settlements.  Jeff talked about Orion & SLS, various ideas for Mars missions & the NASA asteroid mission.  I asked Jeff what he was positive about & he replied the Russian space program & SpaceX with Elon.  He then spoke about some of the Russian programs he follows.  He was asked about space tourism & suborbital flights, then he spoke about SpaceShip2 problems, hybrid engine issues, Richard Branson & more.

In the second segment, he had more to say re SpaceShip2 & Branson.  Next, he was asked about space debris cleanup ideas being skeptical of them.  He was also skeptical of propellant depots.  He spoke about small boosters costing much more than using one large booster.  Pooley called in to support everything Jeff was talking about.  Dr. Bell was asked about Dream Chaser.  In general, Jeff was very critical of lifting bodies & their CG problems.  Listeners asked for his assessment of Inspiration Mars & Mars One which was not positive.  In his closing comments, he said HSF was probably mature & needed radical new technologies to make it cheaper & feasible.  I told him he should come back on the show, invite only callers & emails suggesting radically new & different technologies & he could assess the ideas.  Dr. Bell agreed to do that so watch the newsletter for this upcoming program.

We welcomed back Doug Messier, Managing Editor of ParabolicArc.com for this 1 hour 43 minute discussion.  During our first segment, Doug talked about the proposed Google space program involving up to 1,600 satellites for global communication and wifi.  Doug shared with us as much information as was currently known regarding this program, plus he talked about the Loon Project and explained why he referred to the multiple satellite program as “Son of Teledesic.”  While no launch vehicle has been identified Doug and listeners did talk about the possible impact launch services needed for such a large program.  Doug also reported on Masten Space Systems. He also talked about Masten in the second segment.  Many listeners sent in emails about the proposed Google program, some expressing skepticism, some wanting more information.  Doug then turned his attention to Virgin Galactic and he talked about their powered test flights, engine issues, possible hybrid replacement engines, and more.  We talked about the signed up Virgin passengers and PR efforts to keep them informed of Virgin’s progress.  Doug also briefed us on XCOR and the Google Lunar XPrize contest.  A listener emailed in about the decline of the California aerospace industry and state regulatory issues.  Doug had much to say about this.  Before the break, a listener asked for an update on Stratolaunch.

In the second segment, Doug talked about the management changes at Virgin given three executives have left in recent times.  In addition, he said some of the lower level employees were sending out resumes.  In response to a question, he updated us on Virgin’s Launcher One.  We talked about Dream Chaser test flights, the name change at Dryden, & the NASA Ames name.  Near the end he gave us a brief report on Garvey Space, then Dr. Lurio called in and they discussed at length the Virgin hybrid engine issues, vehicle modifications, & the possibilities for a replacement engine.  Doug commented that they may not make it to 100KM!  As the program was ending, Doug said it would be an interesting year, that he thought there would be crewed vehicle flights later this year, and then he shared his thoughts regarding possible commercial crew downsizing. During this segment, I asked Doug to comment on his most exciting and frustrating stories of last year.
