I was reading that the Jovian moon of Europa has potentially 40-100kms of liquid water under its 10-15km ice crust, and I was wondering; assuming you could magically get through the ice, how would the pressure work? Europa's smaller than Earth, so the water would weigh less, but also you could go a lot deeper - as the deepest part of Earth's oceans is only 11km. Could we use a 21st century submarine on Europa, if it somehow got teleported there?
