December 18, 2020 Zimmerman/Batchelor podcast
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

“Spin launch”… How the heck is that supposed to work from Earth? On airless space it might be a great idea. But the payload needs a speed of about 8 km/s as it enters LEO orbit. That’s about Mach 25 at the surface. Plus speed lost to friction in the atmosphere. Military missiles, and the British Skylon spaceplane, have problems with melting from the heat of that friction already at Mach 5 in thinner higher atmosphere. It would be like firing a glowing meteor in the reverse direction. There will be less of it left at 100 km altitude than of a meteorite colliding with Earth, smoking hot fragments of which then rains down on the ground here and there, just like such a “spin launched” payload will. I guess there would be a meteoroid impact like explosion already at the launcher’s muzzle, destroying the thing.
Is it a joke or a fraud? I suppose the difference is whether people are laughing or investing.
