This Youtube video from NASA explains why the moons of our solar system are often more intersting and than their parent planets. From the ocean planet of Europa, the the volacanis Io there’s more scope for exploration than we can imagine and who know what we will find in some of these places? Devilish methane sea onsters on titan? Or perhaps kelp like creatures living in the depths of Europa?
Have a look at this, it’s a great little video… Not mine of course!
