PATIENCE!!</p><p>The instruments will collect information for at least 90 days. Do you realize there are only 8 TEGA ovens? Waste one, and you've lost 12.5% of the data. There are only 4 MECA wet chemistry experiments? Waste one and you've lost 25% of the data.</p><p>TEGA will tell us for sure about water, but only 1 oven is being processed so far. SO for the time being, the unequivocal sublimation of the pieces of ice is pretty conclusive.</p><p>Now if&nbsp;YOU had ponied up an extra 50 million dollars, then maybe there would have been 10 TEGA ovens, and 5 wet chemistry experiments. But they had to work within a painfully small budget for those like us who want to learn lots real fast. If the mission had cost 50 million more, it would have been cancelled and we would have learned nothing.</p><p>Odyssey has a different set of instruments, so was able to detect the probable ice from orbit. That's what it was designed to do. Phoenix does not have those instruments because it's right there and can stick materials in one of the precious&nbsp;8 TEGA ovens.</p><p>If money was unlimited, we'd know much more about Mars and everything else in the Universe. The fact is money is severely limited. NASA's budget is half what it was during the moon missions, and there's a lot more than just Mars to be explored.</p> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

The research required a UV source strong enough to get the PAH's to flouresce. They stated one challenge was to get the equipment light enough and reliable enough to work in space.</p><p>"Andrew Coates, a co-author of the study and principal investigator of the international ExoMars PanCam team, said the challenge is to make the instrument light enough to be flown, and robust enough to survive the cold, minus-120 degree (C) Martian nights. "</p><p>So that implies that this particular paper is not relevant for Phoenix.</p><p>However, that doesn't mean the same principles can't be applied, but with no UV source (other than solar) the 1.5&nbsp;micrograms PAH cannot be detected.</p> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Here is a brief reason I feel that way. </span></p><p><span style="font-family:Verdana">When the raw images come in they are&nbsp;three&nbsp;filters </span><span style="font-family:Verdana">RGB</span><span style="font-family:Verdana"> with a given wavelength&nbsp;that they combine to make what is called a false color image. Its a false color image because they use different wavelengths for Red, Green, Blue than the eyes uses - they have to manipulate the data to make what they would like to refer to a True Color image. </span></p><p><span style="font-family:Verdana">For example see images below, first one is a image that is taken from their </span><span style="font-family:Verdana">RGB</span><span style="font-family:Verdana"> filters. The second one&nbsp;is from data manipulation required to make that image more like what we see from the </span><span style="font-family:Verdana">RGB</span><span style="font-family:Verdana"> tubes in our eyes. </span></p><p><span style="font-family:Verdana">In other words the data was adjusted to close to the correct colors; there is no reason to think we can&rsquo;t do a similar thing with the florescence.</span> </p><p><img src="http://sitelife.space.com/ver1.0/Content/images/store/6/13/b68c46d7-d349-41b0-8d17-aee961d172b4.Medium.jpg" alt="" /></p><p><br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br /><br /><img src="http://sitelife.space.com/ver1.0/Content/images/store/12/0/1c73e747-8c21-41ab-8007-9ed0bb4529a6.Medium.jpg" alt="" /><br />http://sitelife.space.com/ver1.0/Forums/#</p> <div class="Discussion_UserSignature"> Ron Bennett </div>

They now think they understand the problem with the TEGA doors, that it is a mechanical problem, that an assembly "was not fabricated to flight specifications." However they still think they can get samples in, and plan to try it on sol 30 or 31. The spacecraft went into safe mode and had no operations on sol 27, but they recovered fast and were back to normal on sol 28. They will probably deliver the first sample to the wet chemistry lab nextersol (sol 30). Analyzing a second TEGA sample is the last item on the list for minimum mission success, so that should be done by the end of next week, and they're on track for full mission success by the end of July.READ THE BLOG (from Bob's post above) It' got the kind of detail WE are looking for!!! <br />Posted by MeteorWayne</font></DIV></p><p><strong><font size="2" color="#000000">Cheers for the updates everyone. I have not long been in. I see that that some short cuts may have been taken with the TEGA assembly. I sincerely hope that this will be investigated. At least the ovens appear to be fully operational as do the detectors, so it seems to be a problem with the oven doors opening mechanism. Hopefully nothing else hoses up & a work around for the oven doors can be found. The soil spinking with the scoop appears to be very effective, so careful sprinking of soil over partially opened oven doors should work IMO.&nbsp;</font></strong> </p><p><strong><font size="2" color="#000000">Wonder what the cause of the Safing Event was & why nothing on Sol 27? Now e know, sort of. Cosmic Ray strike, as that thin atmosphere has little stopping power of high energy radiation IIRC??? Anyway, Phoenix was back in operation very quickly & that was an amazingly productive Sol 28 by the looks of it.</font></strong></p><p><font size="2"><strong><font color="#800000">{EDITED, got round to reading the blog. I see the Safing Event was due to Phoenix receiving fresh commands whilst still running other older commands.

Despite these hangups, Phoenix is performing extremely well really & am looking forward to the science reports when samples & images are formally analyzed. I think a great deal of science has already been accomplished.&nbsp;</font></strong></p><p><font size="2" color="#000000"><strong>Looks like Phoenix has already been granted a 30 Sol mission extension, provided she's still operational on Sol 90. That's great news. I see that Barry Goldstein is hoping to push that to late November at least. By then the nights at the Phoenix site will be getting longer as the Martian Autumn Equinox is only a month later, (at Scandia Colles it will be the equivalent of early September on Earth then).</strong></font></p><p><font size="2" color="#000000"><strong>Literally 2 Sols after Mars comes out of Solar Conjunction on Christmas Eve, it will be the Autumn Equinox on Boxing Day. If Phoenix is still operational then, we should get to see CO2 frosts starting to build up & temperatures plummeting, by both day & night.</strong></font></p><p><strong><font size="2" color="#000000">Andrew Brown.&nbsp;</font></strong></p> <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

Thanks for the earlier post. Yes I really, really hope they find proteins like that in the TEGA. As you say above, they need to be 110% sure if living material is found. If they announce to the world that they've found life, then it turns out to be a false reading & that no life was present, they would at best look like a right bunch of muppets & at worse, the reputation of ASU, etc would be badly damaged, possibly beyond repair.&nbsp;</font></strong></font></p><p>&nbsp;</p><p><font size="2"><strong>I know its sounds labourious, it sounds tedius, it sounds crap, but THEY MUST retest, retest & double retest, before shouting from the rooftops. Only then can they be sure of either positive or negative results in this respect of the mission. If not sure, they have to sit on the fence & admit, the results were inconclusive. IMO that is what the end result will be. We will have interesting chemistry, some possibly organic materials to report for sure, but IF they are sure that simple nematode worms, etc have been found, then this will be the biggest scientific discovery, since, goodness knows when & we are alive to witness it.&nbsp;</strong></font></p><p><font size="2"><strong>Andrew Brown.&nbsp;</strong></font></p> <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.
