A submarine mission to Europa?

Hey Spaceguy. I haven't had a chance to really read into it yet. I will do so when I have more time, but what I did read, so far, was talking about the problems they will have, deploying a parachute to get to the surface of the moon. As I said, I will read up on it this evening when I get back, and contact you via email. I Googled "Submarine on Europa" and a bunch of stuff came up.
