Titan and Rhea

Back in 2009, the Cassini spacecraft took this picture of Saturn’s moons Titan and Rhea. The two large moons are very different. Rhea is airless, cratered, and rocky. Titan has a lakes of liquid hydrocarbons and a nitrogen-rich atmosphere even denser that Earth’s.

  1. Elon Musk aka The Real Life Iron Man just put a Tesla Roadster in orbit.
