The Senate Lunch System was flawed from the start. Its not a space program, its a political pork & white collar jobs make-work program.
The goals of those programs are laudable, but the mission profile was optimized for domestic politics rather than achieving the stated goals.
There are cheaper ways than a Lunar Gateway to accomplish building a fusion & rocket fuel refinery on the moon. Orion only makes sense in conjunction with a Lunar Gateway & SLS. SLS is disposable oldtech & a triumph of pork barrel politics over sound engineering.
