While we humans carry on with our daily lives down here on Earth, perhaps stuck in traffic or reading blogs, or just enjoying a Springtime stroll, a school-bus-sized spacecraft called Cassini continues to gather data and images for us – 1.4 billion kilometers (870 million miles) away. Over the past months, NASA’s Cassini spacecraft has made several close flybys of Saturn’s moons, caught the Sun’s reflection glinting off a lake on Titan, and has brought us even more tantalizing images of ongoing cryovolcanism on Enceladus. Boston Globe has another beautiful collection of images form Saturn.
