This is a really easy LPI to love. The slides are lovely and intuitive, partly because Europa scientists have had tons of time to salivate and trade graphics.

If you were an alien looking from a distance at this solar system, you could be forgiven for thinking Europa was the most likely place to find life. Mars life is just talk, Venus, Titan, Triton, Enceladus, sure maybe; but there really actually might be something going on inside Europa. The difference is huge because Europa has been going like this since longer than Earth has had a solid surface.

So why not fly a lander with a drill instead of Clipper? Because you don't know where to land, and how much of what kind of drill to bring. The range of what the crust thickness can be has kilometres of error involved. Europa Clippers primary mission is to find a good spot, which happens to involve collecting a ton of science anyway. 

This LPI is a very excited preview. The closer the mission gets the more enthused the scientists get. You can really feel it. Like they're planning their haul before they go trick-or-treating.  

• That slide at 10 is gif worthy by itself. Showing the IO flux tube aside Europa's induced magnetic field.
• At 16:30 the concept of "subsumptions". Basically a forced rifting in sort of a slip-strike sort of way. But that's awesome, because it's not a common thing on Earth, but may be a regular thing everywhere else.
