"The inside probably tastes different"- Steve D. Vance

Take note of this young speaker. Steve Vance may become a household name by the time of and after the Europa Clipper. He's a very good speaker, and has been a regular background player in just about everything in the outer solar system. Regular PBS & BBC level documentaries often feature Carolyn Porco, Fran Bagenal, and Robert Pappalardo (who makes a brief appearance) and Vance has been working near them all along. He may one day become one of the great rock-stars in planetary science like they are.

• Check out this wonderful slide at 3:50. I wish more such slides came with pre-mission probe lectures. Connecting the instrument payload with the science they hope to glean.
• This speaker often uses a lot of busy X-Y slides, but like the one at 12:55, you can unpack them if you pause and read before listening. Note how it's implicit that he has five of these profiles for the five most studied ice-worlds. He only goes over this particular one for Europa though.
• Slide at 19:40. The word clathrate keeps coming up. A clathrate is a crystal that has some other compound imprisoned inside it, like a hydrogen in a buckyball or a fly trapped in ice. Clathrates are very relevant in ice-worlds because they will be around odd places. You can think of Ice-3 forming around benthic clays, or Ice-3 forming around a brine in the water-column then snowing-up. It depends on the temperature and pressure. On Callisto, the snowing-up clathrates are very possible, on Europa the clay-clathrates are very likely. You can have more classifications of ice, but also salts and for sure there will be unusual clathrates few but the experts, such as our speaker, have even thought about. This is one of the most exciting things about ice-worlds to me. 
• Conclusions at 27:30.
  

Alright, lets get sci-fi for a second. If you want to live on a Galilean moon, where, specifically, do you want to live? I would argue wherever one bar is. Looking at Jupiter may sound nice, but Jupiter is brutal. You would not want to be where you can see it, and radiation can get you. So you dig, and you get so deep you are at Earth-like pressure; now where are you? What do you have? What does the ice taste like?
