We welcomed our guests back to The Space Show for a two hour wide ranging discussion on multiple topics.  Perhaps the best way to summarize what we talked about, mostly in order too, is to pay attention to the Tags as I took them directly from my notes taken during our discussion.  For your convenience, I am repeating the Tags below:

"Tags:  Dr. Jim Logan, Dan Adamo, Artemis 1, reentry trajectory, lunar south pole, NASA PR claims, misleading of the public, Mass to the Moon, Saturn 5, SLS, optimizing SLS, Apollo 17, Starship questions, 7 heavy lift launches for Moon, life support concerns, what comes after landing on the Moon, Shuttle plus ISS cost, flag and footprint mission, human spaceflight safety, deep space compared to LEO, Gateway, sustainability concerns, space radiation, no safe haven concepts in missions, space settlement, artificial gravity, testing Mars gravity, gravity prescription, fetal development in space, Deimos & Phobos very valuable, importance of small bodies in space, space medicine progress, old age and space radiation, long duration spaceflight and sailing ships

Like I have done with previous programs, for the rest of this short summary I will hit some of the highlights from my perspective starting with the opening that focused on Artemis 1 and the trajectory with information provided by Dan.  When you listen to Dan during the first portion of our broadcast talking about the NASA aggressive trajectory, the return which had not been done before, then the misleading PR claims along with the misleading claims about SLS being the most powerful rocket, I suspect you will be somewhat startled.  I don't believe we heard any of this before, even through space news sources.  Listen carefully to Dan and then post your comments on what you heard on our blog.  Let us know your opinion on the misleading information, trajectories and PR.  Toward the end of this part of the discussion, Dan was asked why we should care about any of this as it seemed petty.  Dan did say some of what he was going to talk about was trivial but in the end, if we are mislead on the trivial, what about on information that is not trivial?  Blog comments anyone?

I thought our guests talking about questions to be answered for Starship was a valuable part of the discussion.  Much was said in the hopes of not seeing yet another flags and footprint set of missions as we prepare to return to the Moon.  This then led to a discussion about the fact that SLS was not optimized for the mission.  This part of the discussion was detailed and a bit lengthy.  It also included commentary on the Gateway, some human medical factors including radiation and the difference between being in deep space as compared to LEO.  Much of this discussion was about Starship and returning to the Moon. 

I also liked the part of the discussion during human spaceflight history commentary about the concept of safe havens and the fact that no missions plan or allow for a safe haven should an emergency emerge.  There were also stop and think comments about fueling up on the Moon, dealing with the lunar environment which has not really been addressed in any mission planning which Jim said showed that NASA was not that serious about any of this.  What do you think?  Are they serious?  Are they skipping over or omitting major mission design components?  Our blog awaits your comments.

As we turned our attention toward space settlement, Jim had lots to say about partial gravity and artificial gravity.  He once again pointed to the work of our friend and frequent Space Show guest Joe Carroll for his excellent artificial gravity work.  Dan also had much to say in this part of the discussion as to pointing out weaknesses in plans to the degree that they are plans.  Note the use of the term vaporware from time to time by our guests.  During our artificial gravity conversation, Artificial Gravity John from Fremont called in.  He confirmed that Dr. Logan coined the term gravity prescription and Jim told us the short story behind that.  Jim said that settlement eventually included children, schools, etc, so to think of a space settlement without any of that was to think about something not really a settlement, even a retirement home type location.  John talked about the gravity prescription and asked Jim many questions about fetal development. Jim was even asked about the fetus developing in neutral or zero gravity here on Earth because it was in a fluid bag in the womb.  Don't miss how Jim addressed that frequently stated comment.  He also said test for Mars 1/3 gravity first because if it does not work for humans, anything less than that like the Moon would also not work.  Jim then said the Deimos and Photos were the best and safest places to go for Mars, that they were the most expensive pieces of solar system real estate but that Deimos was better than Phobos. He explains the why of all this in his commentary.

Jim was asked about space medicine progress. He said we were progressing but not fast enough.  He had much more to say about Artemis 1, Dan said that using LEO for space medicine was a low bar.  Our guests used sailing ships as a metaphor.  I'll save all of that discussion for you to hear yourself.
