Brine on Mars?

Bagels writes "A new article on MSNBC (coming originally from Space.com) reports that the both Rovers may have struck water in the form of brine. The Opportunity rover found hints of salty water in the trench that it dug, and scientists note that the Spirit rover is currently digging a trench of its own to investigate the soil that clings to its treads, suggesting the possibility of moisture. The brine would only be small amounts of water mixed with salt, which can exist in liquid form at very low temperatures. More images are available over at NASA's rover site." Reader frovingslosh would like to add: "I'm just hoping that when you get around to posting one of the many stories that the rover has found mud on Mars that you might include a link to the slashdot article where I predicted this but got moderated as 'funny'." Done!
