You do understand that's the point of this test, right?

Bob doesn't understand much of anything.

I'd really like to see those solids replaced with liquids, especially
since SLS is going to be carrying Orion.

Unfortunately, the development costs of F-1 powered boosters would be
quite a bit higher than the development costs of advanced solid rocket
boosters being proposed by ATK. That and ATK (at least in the past) has
had strong political support. Liquid boosters will unfortunately face a
long, uphill battle.
