Once Upon a Water Planet - March 12, 2002
Images taken by the Mars Orbiter Camera (MOC) on board NASA's Mars Global Surveyor spacecraft have shown that gulleys on the surface of Mars look as if they formed much more recently than once thought and that Mars could be going through massive short term climate changes where water could come and go.

While testing its instruments before beginning its mapping mission NASA's Mars Odyssey spacecraft found evidence of water below the surface in the warmer regions of Mars.
Analyses show water stayed on Mars longer than previously thought - November 26, 2001
Using data returned from the Mars Orbiter Laser Altimeter (MOLA) on the Mars Global Surveyor (MGS) mission indicates the presence of small gullies at high latitudes on Mars that were formed in the very recent past and may still be active today.

Search for Life
Determine if Life Ever Arose On Mars
NASA has four science goals for their Mars Exploration program. The first goal is to determine if life ever arose on Mars. This explains that goal.
NASA Origin's Program
NASA's Origin's Program goal is to to discover which extrasolar planets might be conducive for life, and to detect actual evidence for life on one or more of those planets.
The mission of the SETI Institute is to explore, understand and explain the origin, nature and prevalence of life in the universe.

Terrestrial Planet Finder's (TPF) mission is to look for Earth-like planets and then to see if they harbor life. This article explains how to search for life.
Viking: the Search for Life
In 1976 the Viking 1 and 2 landers undertook searches on the Martian surface for the chemical evidence of present or past life on Mars.
Life on Mars
More on the Viking Biology Experiments and the search for life on Mars. NOTE: This was written in 1995 before the discovery of ALH84001 and the debate about whether the meteorite actually contains evidence of life.
Life in Extreme Environments
A New Form of Life - July 30, 2003
Once water flows into Mono Lake, actually a volcanic basin, the only way out is through evaporation which leaves minerals and salts behind. Yet even though the water is now nearly pure lye and twice as salty as seawater microorganisms such as diatoms, cyanobacteria and algae have still been found there.
