Ever dig in soil and hit a rock? Seems NASA didn't expect it. Pretty
stupid.

First of all, NASA didn't design this probe. Second, it was entirely
expected that the probe could hit something that would slow it down or
that it couldn't get through. Making the probe retractable and
repositionable was not a practical option.

Has it occurred to you that what the probe hit was not a rock at all,
but RichA's "brain," frozen and fossilized these billions of years?


I'm not one the with a $$$$$$ probe that's stuck. Whatsamatter? Would adding some COST to the thing to make it work more flexibly have taken away money from the ISS??

Adding another 100 million or so would price the entire mission out of
the Discover Program. It wouldn't even have happened.
