ngement of green colored
patches on a Martian roc over the course of a year. The rock must be
fairly distant from the lander because its image is only about 10 by
20 pixels. They look like lichens. All very interesting. It's clear we
should go back for another look.
	One interesting speculation that I had about this -- if there
is life on Mars, it's quite possible it came from Earth. Since
material from Mars is believed to have traveled to the earth and
landed in Antarctica (by being blasted from Mars by a meteor impact
and eventually intersecting the earth's orbit), the reverse is also
possible. I wonder if the spores of ancient microorganisms would be
capable of surviving the voyage (suitably encased or shielded by
rock)..
