I care very much about science. However, it's not the only thing I care about, and thwarting Russia's endeavours are also right up there. Real lives are at stake as opposed to hypothetical and abstract scientific returns. If Russia's humiliation causes Putin's regime to collapse quicker then I care about that very much indeed.
How much science was really going to come out of this lander, in the grand scheme of things? Why can't that science wait?
