The Space Launch System is more a political tool than engineering need. Congress should not be designing rockets and then mandating they be used. We should use what is appropriate.

From the article:
NASA officials are holding out hope that the first Space Launch System launch can still take place as soon as March despite a delay in the rollout of the vehicle for a key test until mid-February, SpaceNews reports. "Hopefully, we're going to be completing all of the testing to be able to roll out for a wet dress rehearsal in February and then, hopefully, a launch in March," NASA Associate Administrator Bob Cabana said in a talk January 11 at the SpaceCom conference in Orlando, Florida. "That might be tight."
That might not be right ... In a separate talk, Kennedy Space Center Director Janet Petro presented a chart of major NASA missions in 2022 that showed both the wet dress rehearsal and the Artemis 1 launch taking place in the first quarter of the year. Spoiler alert: the SLS rocket is not launching in March, at least not March 2022. NASA officials would do well to be as transparent and honest with the public about this as possible.
