I'm really gonna be excited when we have the capability to dig deep on other planets. Though, I suppose at that time, we would already be able to tell what it's composed of without actually needing to dig - something like radar or active sonar, though not necessarily so. Like at the beginning of Jurassic Park. Getting information about the material, though, I wouldn't know. Waves bouncing against something are affected widely by what something is made out of, so I'm sure that people are working on doing stuff like it, if not have it already.
