Surely, though, science is also about the whys and not just the whats.
I think that's semantics. It's just as valid to ask "Why does this happen?" as "How does this happen?".
If we know that event A will cause result B, science can legitimately ask why it happens. It's not sufficient just to be able to predict that B will happen. However, if B has never been observed, but is predicted by theory, then it is equally legitimate to search for evidence of B.

It's just as valid to ask "Why does this happen?" as "How does this happen?".Newtons laws of gravity does not tell us why gravity exists, or how it works, it merely tells us that all things have gravity, and that in a gravitational field objects will behave in a certain way (i.e. if A has a velocity and position in relation to B, Newtons rules will tell predict what path B will take, but not why it takes that path).
...and it is the validation of those predictions that makes the rest of the theory acceptable.
