Stevehw33 - "And the near total lack of any kind of atmosphere [on Mars]..."<br /><br />Well, you better let NASA/JPL know that they just imagined that the parachutes on MER worked in the "near total lack of any kind of atmosphere" The imaginary atmosphere that transports a bit of water (today) via clouds and frost. The imaginary atmosphere that drives wind erosion, dust devils and global dust storms. It’s just so - totally lacking...<br /><br />Carbon Dioxide (CO2): 95.3% <br />Nitrogen (N2): 2.7% <br />Argon (Ar): 1.6% <br />Oxygen (O2): 0.15% <br />Water (H2O): 0.03% <br />Neon (Ne): 0.0003 % <br /><br />"What we were seeking was rocks that were actually formed in liquid water so that we could read the record in those rocks, not just to say liquid water was on Mars but to learn something about what the environmental conditions were like, would they have been suitable for life and, importantly, do the minerals that were formed have the capability to preserve for long periods of time evidence of former life? <b>That's probably the single most important thing we have found: evidence for minerals at Meridiani that are the kinds of things that are very good at preserving evidence of ancient life for very long periods of time.</b>" Dr Steve Squires 12/04<br /><br />Lack of imagination must be a drag - TWLOM.<br />
