Jon - The reasoning behind the recognition of ice.http://phoenix.lpl.arizona.edu/blogsPost.php?bID=211 Posted by jonclarkerlb2 - Jon that sounds familiar here is my timeline on spotting the sublimation on this board.Keri Bean - When we took the spot on the white stuff, it was very similar to the spectrum of water. It was off the charts in the blue part of the spectrum. This was even better evidence of the white stuff being water ice.06/13/2008 2:27 PMrlb2 - Now take a look  (Third from top) notice the deep bluish tint of the area around the white looking soil. This could even be a result of exposed water ice sublimating in-between frames? This way of looking for movement isn’t conclusive enough to be an exact science, there are a few other explanations that have to be taken into account for it to be bright blue, however – I saw very little of this in over 3,000 color images I processed so far from the Opportunity, or Spirit.http://www.space.com/common/community/forums/?plckForumPage=ForumDiscussion&plckDiscussionId=Cat:c7921f8b-94ec-454a-9715-3770aac6e2caForum:d148ee4c-9f4c-47f9-aa95-7a42941583c6Discussion:436f90e5-d3e9-4c9d-ad0c-2ae4473dfbd0&plckCurrentPage=25&sid=sitelife.space.com <img src="http://sitelife.space.com/ver1.0/Content/images/store/9/9/79834b1b-66f4-4240-9971-9625152d98b7.Medium.jpg" alt="" /> <img src="http://sitelife.space.com/ver1.0/Content/images/store/13/12/ad5506f1-0db9-4f10-bc73-ad99ccb25af8.Medium.jpg" alt="" /> Keri Bean - The final nail in the coffin on the salt theory was when we looked in the trench after a few days and some of the chunks were gone. They must have sublimated, or gone from a solid to gaseous state without becoming liquid, to have disappeared. Salts do not do that.  06/17/2008 5:32 PM rlb2 - There not done baking yet but I thought that this was a little interesting. Is it sublimation, dust settling, or plain old salt? Note, both images were taken at a slightly different angle.Top image sol 19Bottom image sol 21 http://www.space.com/common/community/forums/?plckForumPage=ForumDiscussion&plckDiscussionId=Cat:c7921f8b-94ec-454a-9715-3770aac6e2caForum:d148ee4c-9f4c-47f9-aa95-7a42941583c6Discussion:436f90e5-d3e9-4c9d-ad0c-2ae4473dfbd0&plckCurrentPage=26&sid=sitelife.space.com <img src="http://sitelife.space.com/ver1.0/Content/images/store/14/4/9e211b9e-a0fd-45b3-a41f-14c3df5cb4f9.Medium.jpg" alt="" /> I'm not saying that they didn't eventually figure it out, but we did it here two days before they did....   <div class="Discussion_UserSignature"> Ron Bennett </div>

From the ASU Phoenix Mission website.http://phoenix.lpl.arizona.edu/06_25_pr.php'When doors for a second TEGA oven were commanded open last week, the doors opened only partway. Later, the team determined that mechanical interference may prevent doors on that oven and three others from opening fully. The remaining three ovens are expected to have one door that opens fully and one that opens partially, as was the case with the first oven used. "The tests we have done in our test facility during the past few days show the robotic arm can deliver the simulated Martian soil through the opening with the doors in this configuration," said William Boynton of the University of Arizona, Tucson, lead scientist for TEGA. "We plan to save the cells where doors can open wider for accepting ice samples." Scientists believe the first soil sample delivered to TEGA was so clumpy that soil particles clogged a screen over the opening. Four days of vibration eventually succeeded at getting the soil through the screen. However, engineers believe the use of a motor to create the vibration may also have caused a short circuit in wiring near that oven. Concern about triggering other short circuits has prompted the Phoenix team to be cautious about the use of other TEGA cells.'--As always, hind site is 20/20.  Engineers can learn from the short comings of Phoenix's oven doors and create a  more reliable design of oven doors for future missions.  They mention that a short circuit may have been identified in wiring near the oven.  Does anyone know what systems may be affected as a result of the damaged wires? <div class="Discussion_UserSignature"> Kzoo Kidd </div>

Hi KzooKidd,Welcome to SDC & great first posts.On the NASA Phoenix Blog, someone mentioned that the first soil analysis in the TEGA oven failed. I was aware the lower temperature tests were successful, i.e that sample was dry & some CO2 was released, but apparently it looks as if the 1,000 C test failed????Also on the Twitter site, it is mentioned that the firt Wet Chemistry experiment was successful & results will be announced this morning (PDT, MDT) afternoon (CDT, EDT, UTC, CET, SCET) today.Hi everyone,Does any one know the actual time? One site says 10:00 AM PDT / 6:00 PM CET (UK) another says half an hour later??? Also is this a teleconference, or is it a proper televised briefing, on NASA TV? I'm gettin confooooooooooooooozed!!!!Hopefully, get to find out the actual surface temperature, further weather updates, MECA result & some more colour images / pans.Below another couple of images from Sol 30. Both showing a Polygonal trench border in detail.http://www.photodump.com/Anonymous/lg_7739.html<a href="http://www.photodump.com/Anonymous/lg_7739.html" target="_blank">Sol 30 Polygon border.</a><img src="http://sitelife.space.com/ver1.0/Content/images/store/9/7/997ec7b0-676f-4eb8-8793-8cd3049cf60e.Medium.jpg" alt="" />Another of Polygon border.

To add to the confusion, I checked the NASA TV Schedule and saw this: "June 26, Thursday 6 p.m. - NASA Science Briefing - Phoenix Mission Recorded at the Smithsonian Folklife Festival - HQ(All Channels)I never heard of the Smithsonian Folklife Festival nor did I know why a Phoenix Mission briefing would be held there, so I Googled and found: "On June 26 at 2:15 p.m. on the Galaxy stage, scientists from NASA's Phoenix Mars Lander mission will participate in a Science Update on the activities of the Phoenix Mars Lander, including the lander's recent discovery of water ice." http://www.spaceref.com/news/viewpr.rss.spacewire.html?pid=25759Apparently this presentation is first shown on NASA TV a few hours after the event with repeats Thursday night and throughout Friday.  So there is more than one Phoenix briefing today?  <div class="Discussion_UserSignature"> </div>

Replying to: <DIV CLASS='Discussion_PostQuote'>And sorry Andrew, it is just a teleconference. Posted by MeteorWayne</DIV>Cheers Wayne, Just wondered if I needed to dash home at such speed that I would require a heat shield???????????????????Obviously not. I go at my own pace, about the same speed as the Mid Atlantic Ridge spreading!!!!!!!!!!! <img src="http://sitelife.space.com/ver1.0/content/scripts/tinymce/plugins/emotions/images/smiley-laughing.gif" border="0" alt="Laughing" title="Laughing" />It will still be interesting to get the latest updates though. The event at the Smithsonian Folk Festival looks interesting. 6:00 PM EDT, that'll be 11:00 PM here, not too late, should be able to watch that.By then we should have some of the Sol 31 data down, but the image uploads seem to take quite some time. Sol 30 appeared to take over an hour, one of the slowest yet. Do they put them up as soon as they arrive? I reckon so, as the uploads appear to follow the 37 minute delay each day, to reflect the Martian Sol difference.Andrew Brown. <div class="Discussion_UserSignature"> "I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

Not much news in the teleconference.TEGA completed the first data collection, heating to 1000C/1800F.CO2 was detected (from atmosphere) and some bound water later. These are preliminary results, full analysis will take a few weeks. No ice in this sample (expected results, surface materials, and sat above oven for a few days.The solstice was celebrated last night.Wet chem experiment detected  Mg Na P  ClPh was about 8 to 9.In total, this soil would not extinguish life. Organics not detected yet. It would be good soil for Asperagras or other alkiline loving plants (Turnips were mentioned....yuck). The sample would not be good for acid loving plants. Still, only first sample. Very similar to Antarctic dry valleys.55% of full color panorama has been completed.The short possibly caused by overuse on the vibrator of TEGA oven 4 occurred after TEGA run completed. They'll try and use vibrator less.No problem getting soil into next TEGA oven #5), lots of practice in the simulator. Should only take a few minutes (good for ice)Ovens are labeled 0 thru 7, which explains why oven 4 was at an end.One side 0 thru 3, other side 4 thru 7.Emily (from The Planetary Society) asked a bunch of great questions. Good for her!! All the other questions totaled did not extract more information than any one of hers.As a result of one of them, the intention is to deliver the next sample to all the instruments from one scoop. Full charachterization. <div class="Discussion_UserSignature"> But the Krell forgot one thing John. Monsters. Monsters from the Id.
