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

Special counsel Robert Mueller's search warrants in his investigation of Michael Cohen will be made public with redactions on Wednesday, a federal judge ordered Tuesday.The five warrants in total encompass the searches the special counsel conducted between July and November 2017 of Cohen's emails and other content related to his email accounts, the order said.Chief Judge Beryl Howell issued the order in response to a lawsuit by CNN and other media outlets seeking the release of the court records.There will be some redactions to these documents when the Justice Department makes them public, similar to the redactions made to Cohen search warrants in New York federal court. The redactions will keep secret ongoing investigation details and the identities of people who haven't been charged.Four of the five special counsel's office warrants were referenced in the previously unsealed Cohen documents in New York.Howell told the Justice Department it would need to update her by late August at the latest regarding whether the redacted parts of the warrants should stay under seal. 1098
