<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>The proposal of the 2003 Lander was to embed TEGA & MECA within the body of the lander (SSI & the Meteorolgy station would have been as on Phoenix) enabling a platform to carry Marie Currie, which would be lowered onto the Martian Surface using the Robotic Arm, doubling up as a crane.</DIV></p><p>&nbsp;This seems to be a little 2001, a little 2003. TEGA was never part of either. I don't think MECA was part of '03 ('03 was canceled at essentially the same time '01 was). '03 had (in concept) a real Athena paylod, not APEX + Marie Curie (which was '01).&nbsp;</p><p>The MET station was different than Phoenix's, and the lidar very different--it was boresighted with SSI for dust devil profiling. It's not obvious it could fly like that -- but very fancy on paper.</p>

The three-legged spacecraft has been digging trenches near the Martian north pole since landing on May 25 and its work was supposed to end this month. Phoenix is studying whether the site could have been favorable for microbial life to emerge.NASA spokesman Dwayne Brown said Thursday the space agency will invest about $6 million to keep the Tha$422 million mission going through December.It's the second and possibly last extension since the lander may not survive the upcoming Martian winter.Phoenix is the first craft to touch Martian ice with its robotic arm. It will turn into a weather station once its digging job is finished"&nbsp;I should note there is conflicting information about the length of the extension. The AP story says end of December, while Leonard David of SDC says end of November. I have seen no official news release yet on the NASA site. <br />Posted by MeteorWayne</DIV></p><p>&nbsp;</p><p>&nbsp;</p><p>That is very good news</p><p>it will turn itself into a weather station soon..</p><p>The photo's we will see when the area turns white will be spectecular (and all we saw till now already was..

By Tariq Malik SPACE.com Senior Editor posted: 28 August 2008 6:51 pm ET "As the sun dips lower in the Martian sky with each passing day, NASA's solar-powered Phoenix Mars Lander took time this week to send a postcard of sorts to scientists on Earth after more than three months studying the red planet. "Phoenix beamed home a view of its trench-filled worksite after surpassing the 90-day mark of its initial mission to hunt for water ice buried beneath the barren arctic plains of Mars. While the Martian days, or sols, are getting colder and the sun expected to dip completely below the horizon tonight for the first time since Phoenix landed in late May, the probe itself is in fine health, mission managers said. "It's doing fabulously," said Barry Goldstein, NASA's Phoenix project manager at the Jet Propulsion Laboratory in Pasadena, Calif. "But I've made it clear to the science team that the warranty's over.""http://www.space.com/scienceastronomy/080828-phoenix-postcard.html A little disconcerting though to read the comments posted after that article on Space.com. Most of us here on this forum are glad of any tidbit of info that comes from our space probes on Mars. </font></p><p><font size="2">Some interesting info that still might be revealed from Phoenix: 1.)The TECP results have not been reported yet. This has the potential to show that liquid water in the form of brines exists at the Phoenix site. The ever increasing water ice frost deposits might be good places to check for this. 2.)The atomic force microscope has just released its first images. The size of the particles detected are about the size of clay particles. Does it have the capability to determine if they actually are clay particles? 3.)TEGA has not yet detected organics. But the release of CO2 only at high temperatures at least raises the possibility they could be there. Provable detection of organics would be major big story. 4.)Clouds over Phoenix are increasing in size and density. Could we see by the end of the mission water ice snow on Mars? Others?

Clay would also explain the sticky cohesiveness of the soil. Clay has been confirmed at both the Spirit and Opportunity rover landing sites and has been confirmed from orbit in localized deposits.<br />&nbsp; Clay is very absorbent of water. Clays and other water absorbents such as zeolites have been proposed to explain the high water contents on Mars detected from orbit. If such water absorbents on the surface immediately absorbed the water, would that effect the TECP results?<br /><br /><br />&nbsp;&nbsp; Bob Clark<br /></font> </p><p><font size="2">&nbsp;</font></p> <div class="Discussion_UserSignature"> </div>

<p><font size="2"><strong>Thanks Bob.</strong></font></p><p><font size="2"><strong>Yes I wonder when the TECP results will be released. My guess is that it takes time for them to be properly analysed. Also the exact compostion of the regolith as determined by TEGA as well as the SSI multispectral images. How much of it is volcanic fallout, impact ejecta (Heimdall Crater), sediments dare say from a long gone sea? How much mixing has happened?</strong></font> </p><p><font size="2"><strong>Also it will be useful when we get to see the post Sol 99 Weather Reports.

Near horizon.)</p><p>The pictures in the whole animation are taken about a second apart over 30 secs or so.&nbsp; These are just two frames.&nbsp; It's possible that the "objects" might be in other images but showing much less brightly.&nbsp; It's hard to tell and to feel reasonably confident it isn't a cloud effect.&nbsp; But, these two images certainly don't look much like a cloud reflection.</p><p>Could it be Phobos or Deimos or is it something else?&nbsp; Star?&nbsp; Meteor?&nbsp; Whatever they are, they certainly aren't bright for long. A couple of seconds at the most in each section they appear in.&nbsp; Could we discount a cosmic ray hit if it's not Phobos or Deimos?&nbsp; I haven't seen examples of cosmic ray hits on imaging equipment from Phoenix and am not sure what, if any, likelihood that is of happening.</p><p>Just curious.&nbsp; I would think if it was Phobos/Deimos someone would have caught that and tagged the NASA description for the clip. </p><p>PS - Given all the info available on positioning, I could plug it into Starry Night and try to figure it out.&nbsp; But, I don't have that loaded on this machine and am not as familiar with some of the online tools others can use to the same effect.&nbsp; So, I'll let others chew on it and if there isn't an answer later tonight I'll try to plug in the info and see what I can come up with.&nbsp; I love space/stars/mars and the planets.&nbsp; So, I'm a great pilot but I'm terrible at navigation.&nbsp; IOW, you'd enjoy the ride but would have no idea where you ended up if I was flying around the solar system.&nbsp; :)</p> <div class="Discussion_UserSignature"> <font size="1">I put on my robe and wizard hat...</font> </div>

Might be the Arizona crater... but that is a bit off topic :D <div class="Discussion_UserSignature"> </div>
