I have to wonder why NASA didn't start by building a Saturn V
Can’t get there from here.
Every single electronic component is 60 years out of date and replacing them would need every part, and the sub-systems, systems etc, re certified and tested.
Most if the manufacturers, lowest-bidder, of the 5 million components won’t be in business any more, or the chains to certify their products if they were.
Nobody to manufacture the engines - and they wouldn’t use the methods, equipment or alloys used then - leading back to the certification issue.
Look at the problems they’ve had with the SLS using engines, boosters and electronics they already have - then multiply them a million fold.
might as well ask Boeing to build new 707. They wouldn’t be able to source the parts, have the equipment or jigs to put it together, meet the H&R rules to do so - and then the FAA wouldn’t clear anyone to fly on it anyway..
