We welcomed back Chris Carberry for this one segment 70 minute program discussion on the new administrations space policy including Mars and the Moon.  Chris started off by talking about Mars and the new Space Policy Directive 1 (SPD 1), plus the National Space Council.  He repeated many times the need for those making the policy to stay focused on the goals which he believes should include humans to Mars by the late 2020s to the 2030's.  He supported the Moon as a stepping stone for Mars but also cautioned the need to stay focused on that aspect of returning to the Moon so we do not end up being stuck there and going no place else.  We talked about these issues extensively during the first part of today's program. 

Economics came up, as they usually do, so Chris was asked about our $20.5 trillion national debt, the cost of debt service and multiple recent articles suggesting that even a return to the Moon was unaffordable at this time.  While Chris concurred with the severity of the debt problem, he thought that with the skilled use of public private partnerships and international support, we would be able to do Mars and more.  He said we needed to start doing something. When asked about the findings of the Augustine Commission that the NASA budget would have to be doubled or tripled to do humans to Mars, he dismissed that saying it would not cost nearly that much and he thought those estimates were grossly inflated.  What do you think?  Let us know by posting your comments on the blog.

An important point brought up by our guest as the space trend that seems to be breaking toward Mars.  He also mentioned new films and entertainment programs coming up which he believed represented increased public interest in Mars and space.  He then repeated what he said earlier in that we need to stay focused on the policy and our leaders need to lead with that focus.

BJohn brought up the Deep Space Gateway (DSG).  As you know from his previous Space Show comments, he is not a supporter of the DSG.  He sent us several very critical emails re the DSG but Chris thought it might be better than going to the lunar surface where there was a big chance we might get stuck on the surface of the Moon. He saw the DSG as more of a gateway to other spots in the solar system including Mars.  Don't miss all of what Chris said about being stuck on the lunar surface and the DSG.

Wanda of the northside of Chicago asked why we don't go to the Martian moons given all the economic issues we had been talking about. She suggested this would be easier and cheaper.  Both Chris and I agreed that it would be easier and cheaper but that it was not the mission we wanted as the brass ring is going to the surface of Mars.  Chris talked about going to Phobos or Deimos as a possible precursor to Mars but not as the actual Mars mission.  Again, don't miss all that was said on this subject. 

Next, Chris talked about the upcoming Humans To Mars Summit sponsored by Explore Space to be held in Washington, DC  in May of this year. He also mentioned that the event would once again be live streamed.  This is an exceptional event so check it ou on their website and attend if you can ( 

Marshall called to talk about the DSG, the ISS and more.  BJohn sent in another note, this one pertaining to Phobos and Deimos with EDL and closed loop life support.  Ben sent in a note asking Chris if the planetary protection rules might delay humans to Mars.  Listen to what Chris said in response to Ben's question.  There is a risk of this happening yet there is also a need to prevent any and all types of contamination on mars in both directions. 

Dr. Doug called to suggest that microgravity and radiation would not be a factor for a Mars flyby type mission.  He said the issues could be mitigated and he told us why.  Don't miss this discussion.  Make sure you let us know your thoughts on the subject by posting them on our blog. 

John from Ft. Worth called and mentioned SLS/Orion, noting that it would probably be used for both the Moon and Mars.  If so, it would have more economic value.  Let us know if you agree with John or not.  He also brought up a few other topics during his call.

Adrian got in the last email for day by stating that we would need some form of advanced propulsion if whatever we did on Mars was to be sustainable for the long run.  Perhaps we will start out using chemical propulsion but evolve to the much wanted and badly needed advanced propulsion mentioned b Adrian.

Before we ended, Chris talked about a book he was writing and also a topic he was researching, the use of alcohol in space.  He sought listener  expertise on the subject so listen to what he said just before we ended today's program.  Don't hesitate to get in touch with Chris if you can be helpful on this topic.
