		<description><![CDATA[Mathew Brown&#039;s cost-plus approach may have merit.  I have had experience with a past company wherein a fixed-cost contracting approach was taken with a number of twists; any cost savings realized by delivering below the fixed price were kept by the company and if those savings exceeded pre-set values (say 10% of the overall costs) then the Government further paid the company an incentive award, any cost overruns (regardless of fault) were borne by the company up to an agreed upon level (again say 10%), overruns above and beyond this level were borne by the government.  In return, on a periodic basis (say every 2 years) the company would revise its &quot;fixed-price&quot; either up or down based upon the last two years of performance.  Thus the company benefits by continuing to increase productivity and tapping into the incentive awards (which could be substantial) and the Government is incentivized to reduce overruns from their end to continually drive down the unit costs and thus the overall amortorized costs.  Both entities were at risk if costs went up, i.e. the company in the near-term and the Government in the longer-term.  Note however that this model works when there is a reasonable level of commonality in the product from year to year while still allowing evolution.  I don&#039;t think it would apply well to the one-sy, two-sy approach of current science satellites unless the margins and incentives (particularly to the industrial partner) were fairly generous, at least at the outset.

		<description><![CDATA[I also agree that cost plus is mandatory for the inital prototype and first flights of a new system, otherwise no one will risk capital. But it doesn&#039;t make it possible for innovation of the system. In a cost plus model, innovation does not occur without out a direct request from the customer. Its frustrated a number of engineers i know who have come up with innovations. I grew up around Boeing people.

I have come up with an advanced cost-plus model. don&#039;t have s nazzy title for it but here it is.

After the first few flights on the cost plus model  the buying price is set and any reduction in cost for the contractor, the sell price is reduce half of that. So say its 20% plus cost. a $100M cost will be sold at $120M price for a $20M profit.

If the contractor reduces its cost by 10% the customer now buys it at 5% below the &quot;Set&quot; price.
Costs $90M sells for $114M for a $24M profit. 

This gives them an innocentive to innovate. For any additional costs added due to request by customer for a period of time that is at what ever % of basic cost plus. Also needs to be checks for safety for manrated items and not quite sure what happens when costs go up at no fault of the customer or the contractor. 

Sure the accounting is a little tougher, but if we can send a man to the moon.. ;)]]></description>

		<description><![CDATA[I feel as thought we’ve been packing mules for decades. The time is right to start building the railroad. I believe that is what NASA under VSE is trying to do, at least for the moment. Even if NASA drops out in the future my hope is that privet industry will prevail. Sustainability is key. It will be exciting to see how it all turns out. Just to clear up a possible misconception. I never said cost plus was wrong. That system fit during the time of mules. I only meant to indicate that cost plus is not conducive to growing a healthy market driven program. It may be good for the design and prototyping stages of development. However if were are ever going to have space access, and therefore relevance, for the general public we will need a whole fleet of ships. I know NASA will probably never run such a fleet. But if they can develop the initial infrastructure (likely using cost plus contracts) than privet interest can start to develop mass transit. I guess you could say that in this example cost plus sort of inadvertently fosters a market. My point is. The time has come to start building the railroad that will facilitate our upward expansion.]]></description>

		<description><![CDATA[This is an interesting discussion with many good points.  I would add a couple of observations.

First, there has been a number of comments highlighting the need for a &quot;market&quot; to make space exploration viable.  The implication being that space tourism or space adventures is the logical first market.  While I would agree that these are the current flavor-of-the-month, I would submit that they will never be the spark that unleashes a flood of space exploration.  Europe&#039;s expansion into the New World was not driven by a market, but rather by the perception that there were new, valuable resources to be found and exploited.  Similarly, westward expansion of the US was initially driven by the search for new natural resources, farmers seeking new lands to farm, trappers seeking animals for their pelts, and ultimately, prospectors searching for new ores.  While the farmers and trappers provided a slow, steady trickle to exploration, the discovery of gold in California was what unleashed the flood.  Traditional commerce (the market) followed the source of new wealth and Government was forced to respond to the needs of the populace that had blazed the trail west and in a second way, reap the benefits of the new wealth as well.  The question then is; &quot;What resources do the Moon or Mars have that can ultimately be exploited in an economically valuable way?&quot;  To be sure, a small presence on both bodies is needed to provide the prospecting spark, but Government is not the right entity to accomplish this.  If past expansion is the accurate model, any human presence on the Moon or Mars will naturally evolve to an activity focused on finding new resources to exploit and the resulting generation of wealth that will attract greater numbers of people looking to make their mark if a non-government entity leads the effort.  If Government leads, then it will devolve into an effort of program self-preservation, e.g. the Shuttle and ISS, that is perceived as nothing more than a white collar job works program with no impact on the general public.  This perception leads to a rapid loss of interest by the public as correctly noted in previous posts.

Second, I would agree that using existing lift capabilities is a better approach to the initial exploration than sinking funds into yet another new and improved, bigger is better, launch vehicle.  Multiple launches with either distributed payloads or on-orbit assembly of a single transport system are viable ways of addressing the limited launch-mass capability.  The focus should be in getting there and getting things done than developing new and better toys.  If there are resources to be exploited, new transport systems will be developed to return those resources as economically as possible.  Trappers and prospectors didn&#039;t focus on building a railroad system to get them west, thay packed several mules, put them together in a train, and headed out.

Finally, the comment that cost-plus contracts to space contractors is the wrong approach indicates a lack of understanding of how aerospace companies operate.  Producing spacecraft on a one-sy, two-sy basis will never be done on a fixed-price basis.  The potential of failure in space of essentially one-of-a-kind spacecraft with no means of in-field repair is too great as profit is realized upon success milestones.  Aerospace companies are, for the most part, publically held entities with shareholders.  If the company cannot produce a profit to those shareholders on a consistent basis, investment dollars go elsewhere and the company folds.  The closest they come are commercial sats, and to some degree launch vehicles, with limited modifications that can be produced on a scale large enough to ultimately realize a standard architecture that can reasonably assessed for risk of failure and amortorized over enough units to warrent a fixed-price approach.  Science sats are a long, long way from reaching that scenario.  Note, privately held companies aren&#039;t held a tightly to this model.  Mr. Musk can choose to sink as much of his own money into a space enterprise as he wishes.  No one is going to fire him or cause his company to fold if he fails.]]></description>

		<description><![CDATA[Wow, there&#039;s a lot of good discussion here!

Like Mr. Martel, I&#039;m not particularly sold on most of the Deep Space stuff that we do now, and I question the value of the knowledge that there is an Earth-like planet around another star that we won&#039;t visit for generations.  Especially when we don&#039;t know all of the objects in our own neighborhood.  Sure it&#039;s nice to look out 14.5Bn years to the edge of creation, but what does that serve?

I don&#039;t think it&#039;s a matter so much of of NASA hiring some Madison Avenue type to better flog the public with something they&#039;re largely indifferent to, but rather of NASA going to the American public and asking them what they want the U.S. to do in space.  Do they want us to fix GEO sats?  Do they want us to mine the Moon to build Solar Power Satellites?  Do they want us to look for asteroids?  Do they want us to take a close up look at Pluto&#039;s atmosphere?  Do they want us to watch nearby stars for pre-nova activity?  Do they want us to look for planets around other stars?

Ask the public to prioritize them (say $20Bn to spend on $40Bn of activities) and see what the results are.  And not just a standard 1000 person sample, but lots and lots of folks.

When you think about it, things like SPSes and Lunar Power Towers aren&#039;t going to be built by NASAnauts, they&#039;re going to be built by Teamsters.  That means the kid in shop class can actually think about going into space, as well as the nerd in AP Cosmophysics.  There are plenty of blue-collar Americans who&#039;d be willing to work in space for a year for $100,000 or two.  With that kind of nut you can buy a small business, set yourself up, maybe even send a kid to the community college.  Years and years of wages rolled into one.

Pretty pictures of space are one thing.  A job in space is truly another.]]></description>

		<description><![CDATA[I&#039;m a little too old to have been inspired by Cosmos, but I was certainly reinspired by the imagery in it.

The direct jump to masses of people in space is economically, if not technically, impossible.  But, it _is_ happening.  I think the work initiated by the X-Prize will ultimately lead to that, but, even if everything goes right, it will take decades.  Even if NASA were to dedicate itself solely to that project, and nothing else, it would still take decades.

One thing Apollo and space advocates have both done is over-set expectations.  As I argued in some of my early articles, that is a guaranteed route to disappointment and a loss of faith.  Rule one in both politics and technology is _never_ over set expectations.  It is better to promise too little and achieve it than it is to promise too much and fail.  So, we need to set the highest expectations that can reasonably be achieved and no higher.  (This does not mean that higher achievements will not be made; once a project is started, people start thinking, and, like Apollo, the goal can be beat.)

The fact is, if you look at history, new frontiers are colonized slowly.  

Matthew says, &quot;The plan for the transcontinental railroad was done in 1838, but congress did not deem it important enough at the time. Then the gold rush occured in 1849, 80K people used into calfifornia mostly via overland routes. Suddly easy overland travel was needed. Even so it didn&#039;t begin construction till 1861. Even so the expense would be yeah so to justfy that The Homestead act of 1862 was made to start a massive colonization of the west. The railroad was not completed till 1869. THe west would not be as developed as it is today if it wasn&#039;t for early government subsidies.&quot; 

These figures are comparable to the ones I used in my article, and he proves both my points.  It will take a _long_ time to colonize the Solar System, just as it took many decades to colonize the West under far more ideal conditions than we are dealing with.   If we really want to start this process, rather than just talk about it, we need to recognize that it will take generations and then find the _minimum_ next step that will result in more human infrastructure off-planet and greater transportation requirements to get to it.  Currently, I believe that&#039;s a lunar base with EELVs.  (If someone can think of a smaller step that would get us off-planet human experience, please feel free to suggest it.)  

Otherwise, we&#039;ll create lots of view graphs and dreams about instant success, and probably spend lots of money, and end up right where we are now.

Rule one in both politics and technology is _never_ over set expectations.  It is better to promise too little and achieve it than it is to promise too much and fail.  So, we need to set the highest expectations that can reasonably be achieved and no higher.  (This does not mean that higher achievements will not be made; once a project is started, people start thinking, and, like Apollo, the goal can be beat.)</p>
<p>The fact is, if you look at history, new frontiers are colonized slowly.  </p>
<p>Matthew says, &#8220;The plan for the transcontinental railroad was done in 1838, but congress did not deem it important enough at the time. Then the gold rush occured in 1849, 80K people used into calfifornia mostly via overland routes. Suddly easy overland travel was needed. Even so it didn&#8217;t begin construction till 1861. Even so the expense would be yeah so to justfy that The Homestead act of 1862 was made to start a massive colonization of the west. The railroad was not completed till 1869. THe west would not be as developed as it is today if it wasn&#8217;t for early government subsidies.&#8221; </p>
<p>These figures are comparable to the ones I used in my article, and he proves both my points.  It will take a _long_ time to colonize the Solar System, just as it took many decades to colonize the West under far more ideal conditions than we are dealing with.   If we really want to start this process, rather than just talk about it, we need to recognize that it will take generations and then find the _minimum_ next step that will result in more human infrastructure off-planet and greater transportation requirements to get to it.  Currently, I believe that&#8217;s a lunar base with EELVs.  (If someone can think of a smaller step that would get us off-planet human experience, please feel free to suggest it.)  </p>
<p>Otherwise, we&#8217;ll create lots of view graphs and dreams about instant success, and probably spend lots of money, and end up right where we are now.</p>

		<description><![CDATA[Mr. Brown, your comments on sexy pictures are right on. I too was inspired by Carl Segan’s cosmos. It still inspires me today as I’m sure it does for countless others. However the fact remains that most people see the pretty pictures and think wow that’s a pretty picture. In general they are unmoved by the eloquent notions put forth by Segan or anyone else for that matter. Most people think space advocates are a bunch of Star Trek Convention dreamers who live inside there own little world (some of us actually do). Science has given NASA many tools for public outreach and they have used them well. They no doubt will continue to use them in the future, as will you and I. Public outreach sort of goes with the territory. In order to change the perception of space as a foreign and far away place we need more access. More access can only come through engineering. As a last note on sexy pictures almost everything coming out of the NASA sexy picture department lately either looks like stuff we’ve already seen or are like faces only a mother could love. By the latter I mean the microwave background and the Hubble deep field etc. Don’t get me wrong. I find all the new discoveries and photos to be fascinating and wonderful. But I am a self proclaimed Space Junkie. Most people have the attitude, “If you’ve seen one picture of Mars You’ve seen them all. And the scary thing is that to some extent they are right.]]></description>
