This is the standard release mechanism for planetary mission data, and all of the data is sent to the PDS for distribution; none of it is held back. That is not true, it was held back a minimum of three months, without any good reason, I might add. If they didn't spend so much time dumbing down the American public, they might find that enthusiasm for space exploration wouldn't be waning so drastically, and the space program in general wouldn't be in such a shambles. It was arrogance that pranged the shuttles, and simple inattentiveness and insufficient funding that lost two Mars missions. Thomas Lee Elifritz http://elifritz.members.atlantic.net |

I was answering the question about the release of the MER mission data; you are complaining about how the data is interpreted. I appreciate your response, it was very helpful. I was complaining about both~ The data is released via the PDS. This is the standard release mechanism for planetary mission data, and all of the data is sent to the PDS for distribution; none of it is held back. As to how the data is interpreted, if you have a different interpretation of the science data, you are completely free to analyze it any way you like-- there are plenty of people doing so already, and publishing their analyses in the refereed literature. (The last conference I was at, about half the papers interpreting MER results were from scientists outside of the mission). It's expected that the data will continue to be interpreted and argued over for years-- that is exactly why it's released to the PDS. 'Argued over for years." I'm sure the arguing will continue indefinitely, and there's a reason for that. Genesis, or first life, has certain mathematical properties. As such life stands at the phase transition between geology and biology...by definition. Phase transitions are characterized by intractably entangled trajectories in phase space. So entangled that one can't tell which-is-which. As in a cloud, is it water or air? First life would have the intrinsic property of being as difficult to determine as possible whether it's geology or biology. An Introduction to Complex Systems Torsten Reil, Department of Zoology, University of Oxford http://users.ox.ac.uk/~quee0818/comp...omplexity.html It is that 'uncertainty', when seen in all primary variables of an ecosystem, that constitute proof of life, 'first life' that is. And so it is at Meridiani. Is the soil dust or sand? Neither, but an intermediate grain size. Are those sedimentary rocks formed deep underground and weathered to the surface, or are they stromatolites that formed in place in water? Are the spheres mineral or bacterial concretions? The harmonious uncertainty that defines Genesis is seen in every feature of Meridiani with splendid consistency. There's nothing to argue over, the results are obvious to the naked eye. It's a pity so few can see. Jonathan "THEIR height in heaven comforts not, Their glory nought to me; 'T was best imperfect, as it was; I'm finite, I can't see. The house of supposition, The glimmering frontier That skirts the acres of perhaps, To me shows insecure. The wealth I had contented me; If 't was a meaner size, Then I had counted it until It pleased my narrow eyes Better than larger values, However true their show; This timid life of evidence Keeps pleading, "I don't know."
