NASA: Strong Evidence of Liquid Water on Mars
Scientists have found strong evidence of salt water on the planet Mars, the U.S. space agency NASA announced Monday.
NASA has found lines of "hydrated" salt minerals on Mars. Scientists say these minerals would require liquid water to be created. And where there's liquid water, they say, there could be life.
Jim Green is the director of planetary science at NASA Headquarters. He said during a news conference that "today, we are revolutionizing our understanding of this planet."
Doug McCuistion is the former head of NASA's Mars program. He told the Boston Herald that "if they are announcing that they have found easily accessible, freely flowing liquid water under the surface ... that has massive implications both for the potential for life on that planet and sustainability of humans."
NASA has found evidence of water on Mars in the past. In March, NASA said there was once more water on Mars than in Earth's Arctic Ocean. They say more than four billion years ago, Mars was covered with water 137 meters deep. But nearly all of it has since evaporated into space.
