|The interior of Mars holds vast reservoirs of water, with some spots apparently as wet as Earth's innards. The finding upends previous studies, which had estimated that the Red Planet's internal water stores were scanty at best - something of a surprise, given that liquid water apparently flowed on the Martian surface long ago. The two robots have even spotted signs of ancient hydrothermal systems, suggesting that some places on the Red Planet once had both water and an energy source - two key ingredients for the existence of life as we know it. While the new results should help scientists better understand Mars and its history, they could also shed light on the evolution of large, rocky bodies in a more general sense. 'Not only does this study explain how Mars got its water, it provides a mechanism for hydrogen storage in all the terrestrial planets at the time of their formation.'|
