Does this mean that John Carter wore a heavy coat?
Sure puts a damper on the whole "water on Mars"/"life on Mars"/"let's get humans to Mars for trillions of $$$" agenda.
Mars was 'always cold and frozen'The idea that Mars was once a warm place, awash with oceans that could harboured early life has taken a knock - new data suggests it was always cold, frozen and probably lifeless. A survey of the Red Planet's surface has revealed only traces of carbonates, minerals that should have formed in abundant quantities if Mars once had expansive seas. On Earth, the mineral is found in limestone and chalk deposits around the world. The data was collected by a thermal emission spectrometer (TES) on NASA's Mars Global Surveyor and was analysed by researchers at Arizona State University in the US... "We found carbonate, but we've only trace amounts," said team leader Philip Christensen. "This really points to a cold, frozen, icy Mars that has probably always been that way. We believe that the relatively small amounts that we see probably did not come from oceans, but from the [carbon dioxide] atmosphere interacting directly with dust," he said... "We see so much erosion in canyons, and valleys and plains that have been stripped bare," he said. "It seems unlikely that the carbonate rocks could all be hiding out of view. When you look at the entire planet, you'd think that somewhere a little piece would be exposed."

It is a fact that ice/water is present on mars.
