NASA's Cassini spacecraft made its fourth flyby of Titan, Saturn's largest moon, on Tuesday. At its closest approach, the spacecraft swept past the surface at an altitude of only 1,580 km (982 miles). It took images that will help scientists study the moon's clouds, atmosphere and surface structures. NASA is also hoping Cassini will be able to spot where Huygens landed on Titan in January, to give researchers a better idea of the terrain that the probe landed in.
