Several tons in an opposing solar orbit would make a pretty impressive bang and vaporize a whole lot of ice which might be sampled by a following probe. But miles of ice would be another thing entirely. Not an ethical way to search for life either.

I like the melt idea better. That would require nuclear power of some kind.

<p>How big does a satelite we send have to be to be able to chrush through the ice layer and dive into the ocean on Europa? If a mission should head there, is this a better way of examining the ocean than landing on the surface and drilling through?</p>

# What is needed to break through the surface of Europa?

(Asked by: username_0 on 2014-02-03)

How big does a satelite we send have to be to be able to chrush through the ice layer and dive into the ocean on Europa? If a mission should head there, is this a better way of examining the ocean than landing on the surface and drilling through?

There is no feasible way for a human-made probe to crush through Europa's ice layer.

"It is predicted that the outer crust of solid ice is approximately 10–30 km (6–19 mi) thick." ([Wikipedia](http://en.wikipedia.org/wiki/Europa_%28moon%29))

It's not even known, whether there is a liqud ocean at all under Europa's ice layer.

Instead of drilling one could try to slowly melt trough the ice.
