Posted by MeteorWayne</DIV> Speaking of which.... <div class="address">Phoenix Scrapes 'Almost Perfect' Icy Soil for Analysis</div><div class="promodatepress">07.01.08</div> NASA's Phoenix Mars Lander enlarged the "Snow White" trench and scraped up little piles of icy soil on Saturday, June 28, the 33rd Martian day, or sol, of the mission. Scientists say that the scrapings are ideal for the lander's analytical instruments. The robotic arm on Phoenix used the blade on its scoop to make 50 scrapes in the icy layer buried under subsurface soil. The robotic arm then heaped the scrapings into a few 10- to 20-cubic centimeter piles, or piles each containing between two and four teaspoonfuls. Scraping created a grid about two millimeters deep. The scientists saw the scrapings in Surface Stereo Imager images on Sunday, June 29, agreed they had "almost perfect samples of the interface of ice and soil," and commanded the robotic arm to pick up some scrapings for instrument analysis. The scoop will sprinkle the fairly fine-grained material first onto the Thermal and Evolved-Gas Analyzer (TEGA). The instrument has tiny ovens to bake and sniff the soil to assess its volatile ingredients, such as water. It can determine the melting point of ice. <div class="Discussion_UserSignature"> But the Krell forgot one thing John. Monsters. Monsters from the Id.

The doors are open far enough to get a sample in, so why risk it. As far as using the arm that precisely, perhaps with a few  weeks of practice, something might be possible, but if it's not needed, why give up weeks worth of scince.

The clock is ticking, and when the sun goes away, the mission ends. Posted by MeteorWayne</DIV>That's correct Wayne.Firstly that arm is so strong, that one false move could rip TEGA right off the deck & quite possibly fatally damage Phoenix if the arm pushed down hard onto the deck.It would take weeks of practice to get it right & as you also correctly state, time is ticking. Sols cannot be wasted. The Summer Solstice has now passed, the Autumn Equinox on Boxing Day, not to mention that Mars is in Solar Conjunction just before Christmas, but that is most likely a moot point as by then, it may be getting cold enough for the CO2 to start condensing!   The Sun @ midsol on the Autumn Equinox & the Spring Equinox of course, reaches a maximum of just over 21 degrees. Sky view @ midsol on the Autumn Equinox from Phoenix site. <img src="http://sitelife.space.com/ver1.0/Content/images/store/4/4/649f9415-ffb8-4ab2-84ed-f0bb804b3946.Medium.gif" alt="" /> As above, but without constellations. <img src="http://sitelife.space.com/ver1.0/Content/images/store/5/11/c5972efb-72f1-4798-8ba0-013de3e57059.Medium.gif" alt="" />  Looking south from Phoenix on the Autumn Equinox on Boxing Day 2008. <img src="http://sitelife.space.com/ver1.0/Content/images/store/8/14/d801ee53-b9be-442c-9e7f-968a82d0349c.Medium.gif" alt="" /> Andrew Brown.  <div class="Discussion_UserSignature"> "I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

Latest News from NASA.... <div class="address">Phoenix to Bake Ice-Rich Sample Next Week</div><div class="promodatepress">07.02.08</div> The next sample delivered to NASA's Phoenix Mars Lander's Thermal and Evolved-Gas Analyzer (TEGA) will be ice-rich. A team of engineers and scientists assembled to assess TEGA after a short circuit was discovered in the instrument has concluded that another short circuit could occur when the oven is used again. "Since there is no way to assess the probability of another short circuit occurring, we are taking the most conservative approach and treating the next sample to TEGA as possibly our last," said Peter Smith, Phoenix's principal investigator. A sample taken from the trench informally named "Snow White" that was in Phoenix's robotic arm's scoop earlier this week likely has dried out, so the soil particles are to be delivered to the lander's optical microscope on Thursday, and if material remains in the scoop, the rest will be deposited in the Wet Chemistry Laboratory, possibly early on Sunday. The mission teams will mark the Independence Day holiday with a planned "stand down" from Thursday morning, July 3, to Saturday evening, July 5. A skeleton crew at the University of Arizona in Tucson, at NASA's Jet Propulsion Laboratory in Pasadena, Calif., and Lockheed Martin Space Systems in Denver, Colo., will continue to monitor the spacecraft and its instruments over the holiday period. "The stand down is a chance for our team to rest, but Phoenix won't get a holiday," Smith said. The spacecraft will be operating from pre-programmed science commands, taking atmospheric readings and panoramas and other images. Once the sample is delivered to the chemistry experiment, Smith said the highest priority will be obtaining the ice-rich sample and delivering it to TEGA's oven number zero. In a few days the Phoenix team will conduct tests so the instruments can deliver the icy sample quickly, so no materials sublimate, or change from a solid to a vapor, during the delivery process. The short circuit was believed to have been caused when TEGA's oven number four was vibrated repeatedly over the course of several days to break up clumpy soil delivered to oven number 4. Delivery to any TEGA oven involves a vibration action, and turning on the vibrator in any oven will cause oven number 4 to vibrate as well. The Phoenix mission is led by Peter Smith of The University of Arizona with project management at JPL and development partnership at Lockheed Martin, located in Denver. International contributions come from the Canadian Space Agency; the University of Neuchatel, Switzerland; the universities of Copenhagen and Aarhus, Denmark; Max Planck Institute, Germany; and the Finnish Meteorological Institute.

Since reading here the idea that water is sublimating from under the lander and freezing on the legs I have been trying to find out which way the wind blows on average.  It seemed to me like it would have to come from the southwest for water vapor to blow over the leg.  Lots of places have the recent weather but it took me a while to find a list of the observations.  It looks like overall, sublimated water vapor would be going in more or less the right direction.Canadian Space Agency weather report page: The Mars weather reports are updated regularly as soon as data is downloaded from the Phoenix Mars Lander.
