Hmm, and SpaceX is planning on first test flights of its Starship and Raptor engine as early as next week. They are short Hop flights to test control systems and engines in flight. Static firings have already been completed (using first version Raptors). Orbital configuration would use three Raptor version 2) engines. With NASA plans to outsource launch work, why do they persist burning cash on the SLS program? Other than a Space Force military prerogative. I understand SLS has a stated lift capacity of 130 tonnes, whereas Starship/Raptor engine configurations are specs at 200 tonnes. Details here:
