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?

Bear with me for this example:
In theory, the material of brake disc and pads does expand when hot.
In practice some brakes need to be measured when cold as measuring it hot will read them as too thin. Go figure.
So basically, you can’t be sure to have predicted every variable. A practice test should prove you understood how to correctly apply a sound theory. You may get the theory right and completely miss how it applies.
