Cassini's First Titan Flyby Tomorrow
NASA's Cassini spacecraft will make its first close approach tomorrow to Titan, Saturn's largest moon. The spacecraft will skim within only 1,200 km (745 miles) of the moon's atmosphere, which should allow its radar to penetrate through its thick methane atmosphere and reveal details about its surface. Scientists have theories, but they really have no idea exactly what Cassini is going to discover; whether it's covered in ancient craters, or there are ongoing geologic processes that are reshaping its surface continuously. Cassini will also gather data about Huygens' potential landing site when it arrives at the moon in a couple of months.
