		<description>I also like #11 In-Situ Resource Utilization. #12 Artificial Gravity would be very helpful to achieve #11. Phobos, Deimos and some NEOs may have volatiles. In terms of Delta Vee, Deimos cargo is only about 2.1 km/sec distant from earth capture orbit. If humans could endure 4 rpms and if 1/20 of a gee was sufficient to maintain health, a Deimos or NEO hab could be much less expensive.</description>

		<description>I especially like #12 Artificial gravity. If 1/6 gravity is insufficient to maintain health, we can write off permanent moon bases. We should also do research on human tolerance to angular velocity (w). Perhaps a gradual transition would enable us to adapt to higher rpms.&lt;br/&gt;Since centrifugal force is w^2 * r, doubling the rpms would allow us to cut the hab radius to 1/4 to achieve the same gravity.</description>

		<description>Great topic. NASA recently had a major project to develop technologies need for exploration under the leadership of John Mankins. I spent many months developing a prioritized list of technologies for our company to invest in hopes of future contracts with NASA (some of the technologies were outside of our expertise, such as remote medical care). We were very successful in answering the Human &amp; Robotic Technologies (H&amp;RT) RFP. This program would have funded a sustained technology development effort at ~$1B/yr, half of the work being conducted by universities and NASA, half by private/public aerospace companies. &lt;br/&gt;&lt;br/&gt;That was two years ago. NASA has a new administrator and he made some organization changes. Mankins was forced out. Mr. Griffin needed most of the H&amp;RT money to pay for the CEV/CLV (aka Shaft), and proceeded to shut down the majority of the 118 non-NASA projects (not sure how many NASA awarded projects survived).&lt;br/&gt;&lt;br/&gt;It would seem that NASA believes that they can not afford a broad H&amp;RT like effort and will build the first phase of ESAS using mostly existing technology. Because NASA will not have any money for ESAS phase 2 (LSAM/EDS/Ares V) for many years (2012?) when they can get started they again will have no time for technology development and will have to use existing technology then too. I can see this dynamic occurring again when it comes time to build a lunar habitat and infrastructure. I believe this is a broken model and not in the best interest of our country and does not embrace the spirit of the VSE.&lt;br/&gt;&lt;br/&gt;We did have our chance! NASA chose a different path.&lt;br/&gt;&lt;br/&gt;The list of technologies captured so far is hitting all the high priority needs except for a few.&lt;br/&gt;&lt;br/&gt;Radiation Protection: This may be the single biggest engineering problem there is in space. GCR&#039;s cosmic radiation (GCR), and solar particle events (SPE) are very debilitating and can be deadly. At L1 or on the Moon SPE&#039;s are major risks which must be shielded for. Mass shielding in orbit would be extremely expensive without an elevator/tether available. Mass shielding on the moon would be a given. Travel beyond the Moon and you will be in space for a long time, a trip to Mars will take ~300-500 days round trip using chemical propulsion. Protecting the crew with water shielding around their hab-module is possible (heavy) but I believe this leaves the water un-potable. &lt;br/&gt;&lt;br/&gt;Space Power: I strongly advocated the use of small fission reactors with liquid metal cooling/energy transfer. Learn how to do this on the Moon so you can take the technology to the outer solar system. The problem is that our country is rapidly losing the capability to develop this technology. For all practical purposes the US Navy&#039;s NR group are the only ones with that capability - and you could argue that they do not know liquid metal cooling.&lt;br/&gt;&lt;br/&gt;Nuclear Thermal Propulsion: If we are to ferry in space, we should travel as quickly as possible. I believe that NTP is best &quot;near-term&quot; technology that could dramatically reduce travel times to Mars (this also helps out with the space radiation exposure). A hydrogen based system could even use LH2 to protect crew hab-module, further reducing radiation exposure.&lt;br/&gt;&lt;br/&gt;Highly Advanced Robotics: Because space is a very inhospitable environment we will need to rely upon robots and advanced intelligence agents for most of the exposed work. It is our brains that make the difference in space, our bodies become liabilities.&lt;br/&gt;&lt;br/&gt;Jon, thanks for bringing up this topic. It was challenging to develop a &quot;prioritized&quot; list of technologies that support the VSE. I hope that we will get a chance to use it in future pursuits.</description>

		<description>duh, for all the talk about NASA&#039;s lunar base there is scant little official info available on it. Mark can you enlighent us perhaps on what its going to consist of, where its going to sit at etc? In short, what wonderful properties and mechanics this &quot;market for private sector&quot; is going to have ? &lt;br/&gt;So far, most of official NASA plans i have heard of deal with the &lt;i&gt;getting there&lt;/i&gt; part. In fact, AFAIK, most of the ESAS budgetting so far deals almost only with the getting there part.&lt;br/&gt;Maybe we should take this discussion elsewhere though, to keep this thread on topic.</description>

		<description>Murphydyne states: &quot;Were that it was that simplistic. So NASA&#039;s going to build a base on our Moon that no one else can get to, and say &quot;Here private industry, look, we built a small workshack that we want to give you. You can&#039;t get to it, but you can have it once you figure out a way.&quot;&lt;br/&gt;&lt;br/&gt;No one else can get to? So no one else but NASA can get to the lunar surface (which is where a lunar base would be located)? That&#039;s not a rational statement. What this means is that there can be no private sector development of the Moon--ever. Why this is being asserted, I&#039;m not sure.&lt;br/&gt;&lt;br/&gt;Nor does Murphydyne understand what is being proposed. No one is proposing that someone *give* anyone a NASA lunar base. The proposal is to contract out to private business the servicing of the lunar base.&lt;br/&gt;&lt;br/&gt;&quot;Yeah, that&#039;s going to fly. Rather than partnering with the American people to go to the Moon in a robust and sustainable way, NASA wants to just be pathfinders. But pathfinders are no good if those who follow have to rediscover the path.&quot;&lt;br/&gt;&lt;br/&gt;Huh? That statement makes no sense.&lt;br/&gt;&lt;br/&gt;&quot;(P.S. This is exactly what NASA did with the STS&#039;s external tank component. They&#039;ll carry it up to space, if you show that you can utilize it. Of course the only way to do so is to use the shuttle as your initial base of operations. Chance of arranging to do so? Very, very close to zero. I always wanted to put a belt of ion engines around the middle and boost it slowly up to a higher orbit. But you would have to carry the belt and engines in the shuttle bay. Oh well, too bad, we did offer though...)&quot;&lt;br/&gt;&lt;br/&gt;So private business can&#039;t get to LEO either. I guess COTS is a lie and a fraud too. &lt;br/&gt;&lt;br/&gt;&quot;The Lunar Base is not a market. It is an asset. I can&#039;t just give you an airplane and say &quot;Look! You have a market!&quot; No, you have an asset. And since it&#039;s due for its &#039;D&#039; check it&#039;ll probably end up parked in the desert. By conflating the two you&#039;re making a poor economic argument. And that&#039;s a big component of why your continued championing of the ESAS, Mark, rings so hollow with me.&quot;&lt;br/&gt;&lt;br/&gt;Actually a thing can be a market and an asset as well. The rest of the statement in incoherent drivel.</description>

And that&#8217;s a big component of why your continued championing of the ESAS, Mark, rings so hollow with me.</p>
<p>Oh, and it&#8217;s murphydyne, as in a unit of Murphy force, and a tribute to the great American pioneers Astrodyne, Rocketdyne, Yoyodyne, etc.  Not murphy din, though that is a cute jeux de mot.</p>

		<description>Anonymous called for a wiki on this topic. A &quot;Scoop&quot; site with user enabled comment threads might work as well.&lt;br/&gt;&lt;br/&gt;One space themed Scoop site I know of is run by the Space Frontier Foundation at:&lt;br/&gt;&lt;br/&gt;http://www.frontierfiles.org/&lt;br/&gt;&lt;br/&gt;Post a diary there and registered uses can comment with threaded discussion. Maybe I should get right on that.&lt;br/&gt;&lt;br/&gt;Perhaps tonight unless someone beats me to it.</description>
