Exploring different moons and other space objects is both fascinating and boring at the same time. For scientists, there is much to be taken from a mission to venture out into unknown worlds and seek signs of life or anything that would give us an idea of the conditions in other places found in space. But after a while, it can get boring especially if it takes a long time before you can find something interesting, which might not even show itself to you with a big bang. Now, after Cassini-Huygens, the mission that explored Saturn's Moon Titan, there is another proposed mission to explore Titan with space helicopters.
