<p><strong><font size="2">Hi Ron,</font></strong></p><p><strong><font size="2">Yes I had heard that before, that microbes could act a 'seeding agents' for raindrops as airbourne dust & salt. Then that will have knock on effects regarding cloud development, etc, etc.</font></strong></p><p><strong><font size="2">Regarding microbes in the ice on Mars under the top layer of regolith, I'm very doubtful. Any Martian critters IMO would be very deep beneath the surface, something that can tunnel deep in a future mission may reach them if they exist. Phoenix may find evidence of extinct life, that was living when Mars was more condusive, before the magnetosphere collapsed, the atmosphere largely bled away & volcanic activity waned to the point that the atmosphere was no longer maintained & was being eroded by the solar wind (which is still happening & will get worse over geological time as the Sun becomes more powerful, potentially leaving Mars like our Moon or Mercury).<br /></font></strong></p><p><strong><font size="2">Andrew Brown.<br /></font></strong></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.
