&quot;I think a three part Mars Sample return is probably the only way to do the MSRâ€¦but I see no value in that effort particularly as it stretches out over decades. At the rate â€œautomationâ€ and remote sampling is improving the technology that we put into a Mars collector will be almost childish by the time that a sample return probe comesâ€¦so the samples that were collected will have been done based on the technology of another time. that alone makes (in my view) the notion absurd.&quot;

What&#039;s the hurry? The rocks will be fine. Some of the folks who worked on earlier stages of the project will no longer be around, but the rocks will be fine.

&quot;Second I guess I am not just not willing to sacrifice the entire planetary effort to a few rocks from Mars. sure one of them might contain some wonderful fossil but the odds are against itâ€¦and its a 5-10 billion dollar effort when those dollars would probably get more bang for some buck somewhere else.&quot;

The Survey advises very clearly against this, putting research, technology, small and medium missions all at a higher priority than Flagships. The report advises if the budget is lower than projected, the Flagships should be the first thing to cut, so nothing else in the program gets cut to fund MAX-C, rather the other way around - MAX-C would be the first mission cut, precisely to preserve the rest of the program.

The decision of the Planetary Decadal Survey committee (no scientific slouches there) was that more rovers for the sake of roving were not scientifically justifiable. You &quot;just upgrade the software over time to make them more autonomous&quot;, you say? To do WHAT exactly? To drive around and look at more rocks? Hmmm. Spirit and Opportunity have done great work in their mission, which lasted far longer then they were even supposed to. It&#039;s fairly cheap to keep them driving around looking at more rocks, but the big science questions aren&#039;t going to be answered by just taking pictures of more rocks. If MSR is really unaffordable, the big question is going to be what in situ analysis one can actually afford on a rover, and whether that capability offers science value. It&#039;s unfortunate that the Decadal Survey didn&#039;t consider that. 

That sample return from asteroids and small comets is &quot;just as informative&quot; is a bit puzzling. It may be informative, but it isn&#039;t going to inform anyone about Mars. 

As to JWST being poorly conceived, you may have a point. Though the gain of a factor of 1.7 in primary mirror diameter that you&#039;d get from a 4-meter telescope is no great shakes in terms of enabling new science. Until we learn how to deploy and or assemble large optical quality surfaces, that kind of space astronomy is simply going to have to go on hold.

&quot;However what of the idea, of a few dreamers, to build a probe to the stars?&quot;

Again, to do what, exactly? To answer what question? While the idea can be considered romantic, serendipitous discovery isn&#039;t what the taxpayers pay for, especially when that discovery probably isn&#039;t even for our generation.

That &quot;certainly our generations would gain nothing from it, other than info it gathers enroute&quot; is a marketing spiel that deserves at least a smile.]]></description>

I think that planetary exploration can be justified even without a direct dollar payoff as long as it is efficient. However I think it&#039;s unlikely we can fund a Mars sample return, and should concentrate on launching more rovers (which can be done with existing launch vehicles) and just upgrade the software over time to make them more autonomous. Sample return from asteroids and small comets is much less expensive and just as informative. Similarly I think the Webb telescope was poorly conceived; the next step after Hubble should have been a telescope with a monolithic mirror of about 4m which could have been launched fully assembled on an existing ELV.]]></description>

		<description><![CDATA[Mr. Oler, I do agree with your idea that while a sample return mission was in progress, with tech. advances, we  would be making the mission with old standards.  However what of the idea, of a few dreamers,  to build a probe to the stars?  It may take 100 years for it to reach its destination, and certainly our generations would gain nothing from it, other than info it gathers  enroute.  Should it still be in the planning for the future.  If we wait for tech. and dont try, we will continually be waiting.  Personally I think if there are fossils to be found on Mars, we will have to dig deeper than any programs in the present planning stages call for.  Rather than say a sample return mission, with just a few near surface stones being gathered, Id rather see a real deep drilling rig put on Mars surface.  That is the only way we can get down and dirty.]]></description>
