Mars Rover Finds Intriguing New Evidence of Water
The first drill sample ever collected on Mars will come from a rockbed shot through with unexpected veins of what appears to be the mineral gypsum. Delighted members of the Curiosity science team announced that the rover was now in a virtual “candy store” of scientific targets—the lowest point of Gale crater, called Yellowknife Bay, is filled with many different materials that could have been created only in the presence of water. Project scientist John Grotzinger, of the California Institute of Technology in Pasadena, said during a press conference that the drill area has turned out “to be jackpot unit. Every place we drive exposes fractures and vein fills.”
