A new study of gas in meteorites suggests Mars was bitterly cold for pretty much all of the past 4 billion years, putting the freeze on hopes that the red planet had any extended wet periods during which life could have flourished.
Several rocks that were once near the surface of Mars, and have in the past few million years been kicked up by impacts that sent them to Earth, have been freezing cold for most of the past four billion years, the study concludes.
While the findings don't rule out the possibility of life on Mars, they indicate that biology's best shot would have come in the first 500 million years of the red planet's 4.5-billion-year existence.
"Our research doesn't mean that there weren't pockets of isolated water in geothermal springs for long periods of time, but suggests instead that there haven't been large areas of freestanding water for four billion years," said Caltech graduate student David Shuster.

Everybody wants to know where the water went.
For purposes of discussion, I humbly suggest it is in plain sight......right here on Earth.

The spacecraft is scheduled to be launched on August 10 aboard an Atlas V rocket from the Cape Canaveral Air Force Station. The MRO science instruments and cameras will provide the most detailed study of the Martian surface and the planet's atmosphere ever conducted by an orbiting Mars spacecraft.
