Posted by efron_24</DIV>I agree completely, Phoenix has done a superb job Chris. It was well worth the effort to participate in the campaign to save the inexpensive mission from cancellation. Even if Phoenix fails tomorrow (which it won't), the mission has been an outstanding success IMO, despite those who moan, whine & troll on the comments page say. A truly great mission, glad it happened & have not been disappointed in the slightest.Well done Phoenix.Andrew Brown. <div class="Discussion_UserSignature"> "I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

As far as I know sulfates haven't been found at the Phoenix site. One theory about the lack of carbonates at other sites is acidic soil due to the presence of sulfuric acid as indicated by the abundant sulfates, which would tend to decompose the carbonates. Perhaps the presence of carbonates at the Phoenix site is due to the lack of sulfates and/or to the presence of an alkaline soil. Bob Clark <div class="Discussion_UserSignature"> </div>

I've bookmarked it. Very interesting, well fascinating information was being discussed, yet did not speak down to anyone, quality information, yet not dumbed down.I like those slides that were used. Everyone do not let the YouTube title put you off. It is not all crap on there these days, there is some truly fantastic stuff on there also now, this being one of them.It is a long video approx 48 minutes, but it is a fascinating 48 minutes to sit through & well worth watching. Andrew Brown.  <div class="Discussion_UserSignature"> "I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

That video was really extremely good, the sort of thing that YouTube is hosting more. Also look for Anthmartian videos on there. They are excellent & very uplifting also.

Ran across an interesting factoid to keep in mind when seeing MECA  microscopic images. Mars accumulates about 2 cm of meteor dust every billion years, and since the surface is not recycled, some of that surface dust comes from space! <div class="Discussion_UserSignature"> But the Krell forgot one thing John.

MeteorWayne · Oct 15, 2008

From Mars Daily: http://www.marsdaily.com/reports/Phoenix_Weathers_Dust_Storm_999.htmlThe Phoenix Lander over the weekend successfully weathered a regional dust storm that temporarily lowered its solar power, and the team is back investigating the Red Planet's northern plains. The increasing opacity in the atmosphere from the storm decreased the power reaching the Phoenix's solar arrays. So on Martian days, or sols, 135-136 of the mission (Oct. 11-12), Phoenix scientists and engineers curtailed many of the lander's science activities, such as collecting some data from its onboard science laboratories. The 37,000 square-kilometer storm (nearly 23,000 miles) moved west to east, and weakened considerably by the time it reached the lander on Saturday, Oct. 11. This tamer storm put the spacecraft in a better than expected situation, said Ray Arvidson of Washington University in St. Louis, the lead scientist for Phoenix's Robotic Arm. Now the lander is busy meting out its power to analyze soil samples, collect atmospheric data, and conduct other activities before fall and winter stop Phoenix cold. "Energy is becoming an issue, so we have to carefully budget our activities," Arvidson said. <div class="Discussion_UserSignature"> But the Krell forgot one thing John. Monsters.

Posted by efron_24</DIV>Hi Chris, I find it amazing that Phoenix survived it at all given the power situation. Wonder if some dust was removed from the arrays? There were only six images taken on Sol 135, & they were of the Sun at very low resolution.The landscape did not change.Azm 168.79 degrees Sol 139. <img src="http://sitelife.space.com/ver1.0/Content/images/store/14/5/ee1e259a-e02b-4845-b5db-0b39e71a72fb.Medium.jpg" alt="" />  Remember Chris, The average Martian atmospheric pressure on the surface at the Aeroid (average level with respect to the shape of Mars, new measure of Martian Sea Level that replaced the Datum Line, where average atmospheric pressure was 6.1 millibars), is about the same as Earth's atmosphere is at an altitude of approx 32 KM above sea level.Phoenix is situated approx 4,000 metres below the Aeroid, in Scandia Colles, hense the atmosphere is slightly denser here, but is still only about 7.6 mb, still about the same as Earth's atmosphere some 30 KM above sea level. Winds can blow very fast, & they do, over 400 KPH in some of the dust devils, but there is very little force in those winds, due to the extremely thin atmosphere. Andrew Brown.  <div class="Discussion_UserSignature"> "I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

Posted by centsworth_II</DIV>Hi Centsworth,Yes I think there is only one left unused, not including the Organic Free Blank. Phoenix will now certainly use the entire TEGA assembly, there is enough time & power left.Then it will be monitoring the seasonal change using the SSI, MET & LIDAR.The Arm, TEGA & MECA will run out of power certainly next week, but there will be enough still to operate the SSI & weather station. I think we will start seeing frost persisting all sol shortly over the entire landscape, not just in the trenches & shadows. Hi all,Holy Cow Sol 142 at 13:16 HRS LMST . <img src="http://sitelife.space.com/ver1.0/Content/images/store/13/4/bd2a6b2b-ec5b-4db1-94af-fc873ec17730.Medium.jpg" alt="" />Holy Cow Sol 142 at 13:19 HRS LMST .
