Mars Orbiter Finds Evidence For Ancient Rivers, Lakes Posted by Soulskill on Saturday July 19, @10:16AM
from the shouldn't-the-red-sea-be-on-the-red-planet dept. Cowards Anonymous points out news that studies based on data from the Mars Reconnaissance Orbiter have found that vast regions of Mars contained rivers and lakes when the planet was young. The studies also suggest that the water existed for quite some time, often in standing pools, which are conducive to the formation of basic organic matter. NASA provides a color-enhanced photo of a delta within a crater href="http://www.nasa.gov/mission_pages/MRO/multimedia/jezero-20080716.html">. Quoting: "The clay-like minerals, called phyllosilicates, preserve a record of the interaction of water with rocks dating back to what is called the Noachian period of Mars' history, approximately 4.6 billion to 3.8 billion years ago. This period corresponds to the earliest years of the solar system, when Earth, the moon and Mars sustained a cosmic bombardment by comets and asteroids. Rocks of this age have largely been destroyed on Earth by plate tectonics. They are preserved on the moon, but were never exposed to liquid water. The phyllosilicate-containing rocks on Mars preserve a unique record of liquid water environments possibly suitable for life in the early solar system."

was mars green once?

Dunno if it was green, cos green would require oxygen photosynthesis and it's unlikely that Mars had an atmosphere long enough to develop the amount of free oxygen to kick start green stuff.

 But it might have been a form of plant life that fed on other gases such as sulphur dioxide or methane, which are red and blue (I think).

All those are red, blue, green on earth. No real reason sulphur dioxide bacteria would not have been green on Mars...
