Since it landed on Mars in 2012 NASA's Curiosity rover has been exploring Gale Crater, a vast, dry ancient lake bed with a mountain at its center. Now, Curiosity has found sediments containing sulfate salt in the crater, which suggest it once held salty lakes.A range of salts have been found on Mars in different locations. Researchers interpret these as evidence of ancient brines. Salty water formations seemed to increase on the Martian surface as the planet transitioned to an arid climate 3.5 billion years ago.The new detection of sulfate salts came from sedimentary rocks dated to between 3.3 and 3.7 billion years ago. Curiosity has analyzed other, older rocks on Mars and didn't detect these salts in them.Researchers believe the salt is evidence of the crater's lake evaporating in the Red Planet's arid environment. They also believe studying younger rocks in the future could shed more light on how the Martian surface dried out.Gale Crater was created by an ancient impact, then filled in with sediment layers over time. Mount Sharp, the mountain at its center, was created by wind erosion of the hardened sediment layers. Those same layers act like chapters in the history of Mars and provide clues to its environment at each point in time.At the time the sulfate salts were present, lakes were probably scattered across the crater floor, fed by streams in the crater walls. Over time, the streams would overflow and then evaporate, trapped in a repetitive cycle taking place over millions of years.The findings were published Monday in the journal 1576

Protesters got into a brief confrontation with police outside President Donald Trump's campaign rally in Minneapolis on Thursday night.At one point hats bearing the president's slogan, MAGA, short for "Make American Great Again," were set on fire.Police moved in to put out the fire, apparently angering the protesters."I am so hurt. I am so sad by all of this, truly, that is what it is," said protester Laura Maki. "It's like heart wrenching to me that someone like this can take over our country and hurt people. Truly, I say, every day, it hurts my heart. I just don't understand and I don't understand how people can just ignore this. It just is heart wrenching."There were also supporters of Trump out Thursday night."He is a man that follows action. He said he was gonna do something, he's done at least 90% of what he said he was gonna do," said Wayne Roden, a Trump supporter. "They're making it hard on him to get this wall done but he has already proceeded on starting that and the parts that are already started already seeing less crime."Police briefly fell back before forming a line of bicycles and horses, with one officer using pepper spray amid the protests.Several protesters wore masks, and some chanted, "Hands up, don't shoot!""I'm out here to make our voices heard," said Bruce Wagner, who was protesting. "Abuse of power will not be tolerated. We stand up for the Constitution and our American values."But the protest quickly appeared to ebb, with protesters beginning an impromptu march.Trump was near the end of his speech by then, and the crowd of thousands had thinned well before the confrontation. 1639
