SLS is a bureaucrat/contractors dream, over promised, under delivered, behind schedule, way over budget.
Let’s throw more money at it , that will do the trick.
The problem here is not NASA, it's that dumpster fire of a formerly great engineering company, Boeing.
NASA should be congratulated for the past wonderful decades creating manned lunar colonies, manned Mars colonies, and space stations around every planet and dozens of moons in the Solar System.
Oops—that happened in a parallel universe, not this one!
NASA is a bunch of clowns in this universe.
