Battle of the heavy lift rockets
Check out this very detailed and informative look at unstated competiton between NASA’s SLS rocket and SpaceX’s heavy lift rocket plans that are even more powerful than the Falcon Heavy.
Key quote: “It is clear SpaceX envisions a rocket far more powerful than even the fully evolved Block 2 SLS – a NASA rocket that isn’t set to be launched until the 2030s.”
The SpaceX rocket hinges on whether the company can successfully build its new Raptor engine. If they do, they will have their heavy lift rocket in the air and functioning far sooner than NASA, and for far far far less money.
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

Why reinvent the wheel? Reopen the Saturn V production lines if a heavy lift vehicle is needed. It’s not reusable, but I have grave doubts that mega-rockets could be made reliably reusable anyway.
Those Saturn 5 production lines don’t exist any more. They were shut down in the mid-1970s and are long gone, with many of the individuals who worked on them long retired or even deceased. In addition, the companies that built the Saturn 5 are also long gone.
Moreover, the technology has changed. NASA tried to resurrect the J2 upper stage Saturn 5 engine for SLS and after spending billions on it mothballed it because they found it to be “overpowered.”
Thanks for the update, Bob. One would think NASA would have kept copies of all schematics and production plans given that they paid a vast sum to these companies. Oh well…
It is not simply a matter of having schematics and production plans. You need the right kind of factories and, as you said, production lines. Those don’t exist anymore. You have to retool and rebuild everything.
Far cheaper to start from scratch, as SpaceX has done, using the knowledge gained in the past combined with the technology and engineering of the present, to make something new and cutting edge.
