We have lots! <img src="/images/icons/wink.gif" /><br /><br />I moved this thread from M&L to SS&A because it appeared to be a Mars image analysis thread, not a MGS or MRO mission thread. (That is to say, it's about the products, not the spacecraft or the missions.) But if it moves to discussion of extraterrestrial life on Mars, we do have a forum specifically for that: SETI. There is a requirement that discussion in both SS&A and SETI be scientific in nature, so if this becomes more speculative, it can move to Phenomena, where the rules of debate are much looser. <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em> -- The Tenth Doctor, "Blink"</font></p> </div>
