Here are some incredible shots, of the
Phoenix lander on Mars.
This first shot is taken from the Mars Observer orbiting above the planet.

This next one, is of some white material UNDER the lander. It could possibly be ice, uncovered as the lander's rockets were firing, as the lander made touchdown.

This last picture, IMO, shows indisputable proof, of water on Mars.
