I just want to be sure, as that area that can't be physically be reached by current probes is the only unknown in the equation. I am going to tests on the casing of course! Thinking outside the sphere does not mean forgetting basic science and safety principles! I am sure when many of us mention that we fly rockets to some people, their doubts and concerns about us as "mad scientists" are similar those expressed about this probe idea. I believe it is far safer than exploratory surgery, and it could always be cut out of my gut if I am wrong!
