“Exploration is in our nature. We began as wanderers, and we are wanderers still. We have lingered long enough on the shores of the cosmic ocean. We are ready at last to set sail for the stars," Carl Sagan, Cosmos. In February 2014, Curiosity’s MastCam instrument took this picture of rover tracks across a dune located in an area dubbed “Dingo Gap.”

"Given the recent Curiosity findings, past Martian life seems possible, and we should begin the difficult endeavor of seeking the signs of life," says Jack Mustard, chairman of the Science Definition Team and a professor at the Geological Sciences at Brown University. "However, no matter what we learn, we would make significant progress in understanding the circumstances of early life existing on Earth and the possibilities of extraterrestrial life."
