Will we see the atmospheric pressure increase as CO2 starts condensing out further north due to the air rushing up from the south pole, or will we see it decrease as more and more CO2 leaves the air?

<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>You raise some great questions neuvik.&nbsp;I do not know the actual answers, but what I can do is provide some into for the Sol 124 - Sol 125 period, marking the end of the extrended mission.Now we have a fascinating 34 minimum extended mission to look forward to.Mars in the seasonal cycle is now similar to the end of July on Earth. The 34 Sol extended mission will take Phoenix past the Summer Cross Quarter Day / Sol (Midway between the Summer Solstice & Autumn Equinox approx 3rd August on Earth) & well past the first sunsets.Any guesses as to whether or not we'll see all day frosting or even the first appearance of CO2 frosts????????Tuesday 30th September 2008 / Sol 124 - Sol 125:Sunset 14:15 UTC.Midnight: 16:47 UTC.Sunrise: 19:17 UTC.So the Sun will set for Phoenix for 5 Hours & 2 minutes, crossing over from Sol 124 to Sol 125. What will the temperatures drop to? Will Phoenix survive? Midnight rendition on Sol 124 - Sol 125. &nbsp;Andrew Brown. <br /> Posted by 3488</DIV></p><p>Thanks Andrew!&nbsp;&nbsp;</p><p>Good information on the seasonal situation for the MPL.&nbsp;&nbsp; Approaching the equinoxs I'd say the MPLs situation it going to be fairly dire, the solar irradiance on the solar panels for the days will probably be insufficient for the nights heating. &nbsp; Ofcourse I have nothing to back that up with but a hunch in my head. &nbsp;&nbsp; As for the first all day C02 frosts, I'd say its around those sols you listed as well, but again, just a baseless guess.&nbsp; &nbsp; I think I'll go back and get all the water data and read up on some meterology and see if I can't make some predictions. &nbsp; but really all I can do is make guesses, or look at the current temp, and compare it to the vapor pressure of C02 and say, "yup, well its not a gas at this point. should be snowy" </p><p>&nbsp;</p><p>&nbsp;</p> <div class="Discussion_UserSignature"> <p> </p><p><strong><font color="#ff0000">I don't think I'm alone when I say, "I hope more planets fall under the ruthless domination of Earth!"</font></strong></p><p><font color="#0000ff">SDC Boards: Power by PLuck - Ph**king Luck</font></p> </div>

<p>Did I miss something? </p><p>I thought there was still more of those TEGA ovens available to brew some more soil samples.

We will not know how successful the opening of those will be until it is tried, but I think there is a good chance they will all be successfully used. &nbsp; </p> <div class="Discussion_UserSignature"> </div>

Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>The length of the extension is due to a technicality:&nbsp; the coming end of the fiscal year.&nbsp; A new extension needs to be done in the new year.&nbsp; No rush declaring that extension though.&nbsp; <strong><font color="#0000ff">Everyone knows that Phoenix will operate as long as it can.&nbsp; The only question is how long they will try to contact it after we no longer hear from it and what efforts, if any, will be made to re-contact it in the spring.</font></strong>&nbsp;&nbsp; Worry about cutting off contact with an operational Phoenix borders on the irrational. (Sorry. Little bit of tough love there.) <br />Posted by centsworth_II</DIV><br /><br />When does spring arrive on Mars at the Phoenix site?&nbsp; What are the chances that it&nbsp;will still able to communicate to show the frost increasing build-up this fall?&nbsp; What is the likelihood of contact next spring? <div class="Discussion_UserSignature"> <p> </p><p><em><font size="1" color="#000080">Don't let who you are keep you from becoming who you want to be!</font></em></p> </div>
