Back to the future: NASA engineers today test fired a major component of a refurbished Saturn 5 engine.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

I like this.
Basically dropping back and punting.
They know they have an engine that will do the job. In case they have to use it it will be finally be available.
Rebuilding and then redesigning the engine using modern computer modeling and materials.
The only problem I see the HUGE amount of fuel needed by these engines to reach their intended altitude. These engines were not intended to reach orbit. Different engines were used to do that.
I still think multiple, improved and upgraded solid rockets like we already have, is the way to go for first stage thrust.
But there could be a problem with that idea with the huge payloads they want to lift. Thrust might back-up into the engine(what ever its called to engineers) and could cause the engines to explode.
I would also like to see a plan for an eventual linear accelerator for first stage lift. Something re-usable and all electric.
The sheer audacity of it all, that engine burns through fuel almost like the federal government burns through cash!
