Mars is likely to have at least some water today locked in a frozen layer mixed with the crust . Although I do not think this rock from Mars has definitive evidence of life , it does have organic chemicals that were preserved much in the same way we see things preserved in hot springs on Earth . Observations made earlier this year by the OMEGA instrument on Mars Express showed that Mars has vast fields of perennial water ice , stretching out from its south pole . Mars is right next door to Earth , but it is n't very neighborly . This is wrongly thought to mean " canals , " and is thought to imply that Mars has intelligent life that has built a system of canals .
