Cliffs in Ancient Ice on Mars

Scientists have come to realize that, just below the surface, about one third of Mars is covered in ice. We study this ice to learn about Mars’ ancient climate and astronauts’ future water supplies.

Sometimes we see the buried ice because cliffs form like the one in this image. On the brownish, dusty cliff wall, the faint light-blue-colored ice shows through. Some of these cliffs change before our eyes and boulders of ice can tumble downhill. We take repeat images of these scenes to check for changes like this.

Watts Up With That?

Don`t worry there is no significant man- made global warming. The global warming scare is not driven by science but driven by politics. Al Gore and the UN are dead wrong on climate fears. The IPCC process is a perversion of science.
