"The deepest hole humans have ever been able to create was about 12km deep."
This interesting: We've sent humans 384400 km away from our planet, we've sent an object more than 22E9 km away [1], yet we cannot drill a hole deeper than 12 km into our own planet.

It's hard to engineer materials or machinery that can cope with the kind of pressures and temperatures created when drilling deeper than a few kilometres. Also pouring government funds into something like this is not as glamourous as manned space flight missions. A good example is that we know more about the surface of the Moon than we know about the ecosystems in the Mariana trench.
