Has any one heard of any mission dates to solely explore te poles of Mars, with a rover of some kind. <div class="Discussion_UserSignature"> <p><em><u>SPONGE</u></em></p> </div>

There is a lander scheduled for a polar landing in 2009 IIRC. The Phoenix lander. No rover missions planned as yet to the poles of Mars to the best of my knowledge.<br /><br />A rover mission to the martian poles may materialize in the near future however.. <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.

All the current orbiters image the poles. Phoenix, launching next August, will land at high latitudes in the northern regions of Mars. No planned rovers though. <img src="/images/icons/frown.gif" /> apart from on paper http://gltrs.grc.nasa.gov/reports/2004/TM-2004-213367.pdf)<br />Jon <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em>  Arthur Clarke</p> </div>

you know on time that when Mars is revolving sudden a earth quake occurs and mars had lost its orbit and come back again

sqizee - Hi! Is you user name a euphemism for quizzy, as in asking questions?<br /><br />Certainly that is good for this section of SDC!<br /><br />As your image is waiting for approval, I can only comment on the text:<br /><br />"On time." Indeed, Mar's revolution, and all planetary revolutions are on time - and can be predicted therefore in a very precise manner which makes space probes easier to direct to solar system objects.<br /><br />Earthquakes - on Mars or earth? If on earth - are you alluding to tidal interaction from Mar's as an effect that could trigger an earthquake on earth? Kind of like the straw that broke the camel's back (more specifically the tiny additional force added to the stress between tectonic plates causing a sudden slipping and therefore an earthquake)?<br /><br />Mar's losing its orbit and then coming back again - come again?????<br /><br />Certainly any perturbation of Mar's orbit could cause earthquakes on Mars. Is there some evidence that this has occurred on Mars by some large intruding object - such as the theoretical (perhaps mythical) Orphaeus before impacting earth and forming our moon?<br /><br />I would doubt that Mar's would return to its older orbital path - that would take some fine tuning from an additional perturbing object - extremely unlikely by chance. And why would such a phenomena be intelligently designed?<br /><br />[Note: of course, Orphaeus' impact was extremely fine tuned for our benefit if that is how our moon was formed.]

Mars does not appear the be capable of generating earthquakes for the last hundreds of millions of years, or certainly any large enough for it to have "lost it's orbit". In fact no earthquake could change the orbit to any extant, since the mass all winds up in the same spot.<br /><br />It will be in an orbit very close to the one that it's in even with earthquakes so large it would split the planet into pieces.<br /><br />No need to worry <img src="/images/icons/smile.gif" /> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

I hate asking questions, but I can't seem to find what I want on the net. <br /><br />Is it plausible, or accepted, that the Tharsis region was due to the Hellas impactor and did this shut down the dynamo? New data suggest the martian dynamo shut down 3.5 million years ago. It has been posited that hellas is of the same age. <br /><br />Here's the kicker: Assuming Mars had enough pressure to sustain surface water, how long would it take to strip away to present conditions due to lack of dynamo? <br /><br />Thanks in advance. <br /><br />BTW, this is for a work of fiction.

No, Tharsis is very much younger.<br /><br />Hallas event a minimum of 3.8 GYA.<br /><br />Tharsis Rise about 2.5 GYA. Tharsis volcanoes may just be long term dormant.<br /><br />There is no connection. <br /><br />The original theory came about because Tharsis is more or less directly opposite<br />Hellas. The Hallas impact shockwave travelled around Mars & focused in<br />Tharsis (much like the Caloris Basin & Weird Trerrain on Mercury).<br /><br />When Hellas formed, the mantle of Mars was likely molten with a thinner crust, so<br />the shock waves likely dampened out.<br /><br />So no, IMO the two are not related.<br /><br />Andrew Brown. <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.
