<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Please do Wayne, your scribblenotes will be far superior to my inane ramblings!!!!!!!! But WOW, what a fascinating Press Conference, amazing stuff indeed & so much accomplished. Hopefully those who whine & ***** about Phoenix not delivering can belt up & grow up now. The one question though not answered proerly IMO, though it could have been due to a bad phoneline, was the period of the Martian obliquity variations.The Earth I know has the precession of the equinoxes every approx 25,850 years & the Obliquity Variation (21 to 24 degrees) approx 41,000 years. But that question was never answered properly.Wonder if the Martian periods are still to be thought of 51,000 years (Precession of Martian Equinoxes) & 90,000 years (Obliquity Variation). Looks like the supposed variation of 14 degrees to 35 degrees tilting has been thrown out, with the variation instead of 0 degree to 90 degrees (like Uranus)&nbsp; being more likely with the Phoenix results.&nbsp;Andrew Brown.&nbsp; <br />Posted by 3488</DIV><br /><br />Unfortunately, there's not a real good answer to that, Andrew. It's chaotic, so about the best you can do is define the limits (Peter said obliquity of 60-70 degrees max, but I'm sure that's just a back of the envelope estimate). Trying to predict timing in a multi body problem is futile.</p><p>Perhaps, with future analysis and future missions some general timelines might be discovered from the data (I think there was a comment about that), but when dealing with the interactions that produce the shift in axis (for earth, as well as all other solar system rubble such as Mars) it is an insoluble problem from a mathematical standpoint to any reasonable precision. Espececially for Mars, since it's such a lightweight, and is more strongly influenced by Jove.</p> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

<p><font size="2"><strong>Cheers Wayne, I just threw up notes as they came in, so yes the maximum 70 degree tilt is probably correct.</strong></font></p><p><font size="2"><strong>Yes Jove will have a larger effect, since Mars wth only 11% Earth's mass & orbits closer to the Jovian orbit, will muddle things somewhat.</strong></font></p><p><font size="2"><strong>I found the possibility of the landscape being so young due to the formation of the Heimdall Crater to the N E very interesting. Did not say what sort of time period, only a few tens of millions of years. </strong></font></p><p><font size="2"><strong>That shot of Heimdall from the MRO HiRISE, with Phoenix on the chute descending in front, did make me think that crater looked young, now we have the actual link with the Phoenix data.</strong></font></p><p><font size="2"><strong>However it does hinder with looking for clues with ancient Mars, unless the veneer is thin enough for Phoenix to dig through.</strong></font></p><p><font size="2"><strong>Andrew Brown.&nbsp;</strong></font></p> <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.
