Mars Was Wet 

NASA has announced that findings by the Mars rover Opportunity show that water once filled the Meridiani Planum crater in which it landed. The evaporation of this water left behind salt deposits, implying that Mars once held saltwater on its surface. When the water was present and how long ago it evaporated is not yet known, but scientists hope to gain more information from samples collected outside of the basin.

This announcement is more evidence suggesting that Earth is not the sole planet capable of supporting life. Stars tend to grow and shrink throughout their lifecycles and it may be that our Sun was once larger than it is now. Such a condition might have been more favorable to life on Mars, while the Earth was little more than magma. If we find evidence for simple life on Mars, how old will it be? How long might evolution have been allowed to progress on Mars before it became sterile? Could life have migrated from there to Earth?
