The whole Constellation program was a complete failure from the beginning. And it was rightfully killed, in fact, it lived far to long, was a complete failure in literally every aspect. Obama tried to kill it.

But congress couldn't let the money river go, so they rescued Constellation and turned it into "Constellation 2.0: Even Dumber". Instead of actually having a mission it was literally just 'continue to build more or less the same thing' but without any mission.

This resulted in SLS and continued Orion. And for years they didn't have a mission. Literally just build to keep existing contractors.

So this whole architecture is literally just 30 years of gigantic waste of money without any result. The resulting rocket sucks, is incredibly weak and has a terrible launch rate. To even match the Saturn V it would take another 5-10 years and cost another 10 billion.

So really, I don't like Trump. But finally get rid of these terrible milestone that have been holding NASA back for literally 25 years is worth any short inconvenience and will improve NASA in the long term.

The worse parts are the science cuts.
