Mars: the perfect conditions for life? - Life on Mars - BBC Horizon science

BBC Horizon show 'Life on Mars' examines satellite images of what seem to be dried up river beds. Could Mars have ever supported life? Although the Viking probe images make it not possible to confirm of deny the existence of rivers, the latest probe images give a much more powerful insight into the past climate on the red planet. Brilliant video from the BBC science show.

Good news: It is snowing on Mars. Google for further information ;)

...so Mars was once much warmer than it is now, and we know from earth history that it was once a giant snowball. Does our sun go through more extremes in power output than is generally believed?

Mars is a giant living fungus that was launched from a giant cog in space....lol

The truth, Mars is a giant brain.

@robinsgirlwonder well if they where made by lava my opinion is that it dried up and disappeared a long time ago then the water molecules built up over time and then froze in the trenches
