I’m sure they did this whole thing on paper before executing, but why did they need to actually do it?
Normally, I’m all for funding space agencies, but there doesn’t seem like a whole lot of value in doing this. If you know all of variables in concept, you should be able predict that it would work. Right?

Sure. But… if there is a giant asteroid about hit Earth we probably want to be really sure that it works. Like not just ”we ran the numbers” sure but actually have done it sure. There is also a lot of practical experience that doing this achieves. Building a spacecraft in theory doesn’t allow you to find and solve all the problems you run into when really doing it.
