Washington, - Mars once had a salty sea that could have supported life, NASA said Tuesday, citing evidence that its Opportunity robotic probe is exploring what was once a shoreline. Opportunity and its twin Spirit landed on Mars in January on a mission to search for signs of whether life ever existed there once. "We have an environment that's suitable for life," Squyres added. Rock formations that Opportunity has studied were formed by saltwater sedimentation, NASA officials said. Scientists cannot yet determine when the sea existed, or even its size. Ed Weiler, NASA's associate administrator for space science, said the result "gives us impetus to expand our ambitious program of exploring Mars to learn whether microbes have ever lived there and, ultimately, whether we can." The results were checked by independent experts before being made public, NASA officials said. "This dramatic confirmation of standing water in Mars' history builds on a progression of discoveries about that most Earth-like of alien planets," said Weiler.
