Mark Lemmon, atmospheric science professor at Texas A&M says Gale Crater was selected as the landing site for several reasons. “It contains a large mound that is almost three miles high, but it is made of sedimentary rock,” he notes, adding that data from orbiting satellites shows near-certain proof that water was in the area at one time.
John Grotzinger, chief scientist in the Curiosity team, says a recent soil sample analysis shows something earthshaking, "This data is gonna be one for the history books. It's looking really good.” Grotzinger's team won't be ready to talk about the discovery for several weeks.
Samples of Martian sand and dust from the Rocknest site bears a remarkable resemblance to Hawaii's volcanic sand. Although Curiosity has departed Rocknest, the rover's arm is still holding some soil from the fifth and final scoop it collected there. It will be available for analysis if scientists so choose in coming days.
Tomorrow, Curiosity should be situated at its overlook location, called 'Point Lake' taking in a restful Thanksgiving.
