Evidence for Water on Mars

Mars, a possible site for life in our solar system

Erosion features on Mars resemble those seen on earth

 

Mars orbiters have mapped the current water availability of the planet.

Frost collects on Opportunity during the night.

Martian sedimentary rocks and layered rocks along a road cut.

Martian "blueberries". Note the presence of layered sedimentary rocks in the first image. Blueberries form under the influence of water.

Blueberries, popcorn, and nuggets

Other Possibilities for Life in our Solar System

Europa and other moons orbiting Jupiter

Io has an atmosphere and is geologically active. It is possible that it could support life.

Europa (also a Jovian moon) is surrounded by a sea of frozen organic compounds and water. Deeper down, the material is liquid and could support life.

One of Saturn's moons, Titan, has properties that may have allowed the evolution of life. Cassini Mission is here. A quickie on the Cassini-Huygens mission is here.

In ice on the moon? Bacteria on the moon.
