When Solar System scientists got together to discuss how Jupiter's mammoth atmospheric storms, Martian soils and evidence of lakes on Venus relate to the search for life's origins, they decided they have only glimpsed what may be Out There. They wanted to do more. Ancient inner planets. Scientists have discovered that Mars, Earth's nearest planet neighbor, once had more atmosphere.
Martian soils show that lakes and deep rivers once covered the Red Planet.
Large storms seen on Jupiter suggest a natural laboratory for chemical evolution. Scientists also have found oceans of something on Jupiter's satellite Europa. Such discoveries help trace the origins of Earth, the Solar System and life itself. Titan may help explain the origin of life.
