The whole reason for a lander was to drill, capture, bake, and sample the surface. How do I know? I'm working on a nearly identical mission for NASA that will go to permanently shadowed craters on the poles. Because it's a cheaper mission the success criteria is very limited. We must land and take data. But the whole reason we are going is to drill, capture, bake, and sample. That is the only way to really know what is there. If we fail that everyone on the mission will feel we failed. But as long as we land and get some data from the instruments the PR will be spun that we succeeded.
