In regards to Europa, what are the limitations regarding current data transmission technology.
Say we were to have an orbiter circling Jupiter, a lander on the surface of Europa and a "swimmer" [submarine] that somehow got under the ice, and liquid water existed under the ice.
Using current technology, how could the "swimmer" talk to earth? (Aka "phone home") Would a wire be needed to penetrate the 2-8km of ice? (Can radar penetrate that far?) How far could the "swimmer" communication penetrate?
- From the bottom of the Europa ocean, to the surface?
- Through the ice, and to an orbiter?
- All the way to the deep space network?
I am specifically curious about the limits of current data transmission capabilities of an object buried under 2-8km of ice. (Is the thickness of the ice relevant?). Data transmission rate isn't necessarily relevant, just distance through various mediums such as ice, water, and open space.
