Genesis cover

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

    This video explains how this came to be and who conceived it.

    The link Bob provided at the top is an attempt to convey the spiritual and emotional experience of being there.

    This much longer video ( ) shows much more detailed views of the facade statuary with identification and explanation of the reason for the drastically different styles, the different colors of the windows, and includes a tour up the inside of one of the towers.

    i am continually amazed at what a human mind can conceive and what human hands can build.

    I toured the site in 2001 and the advancements since then are tremendous. It was a pure construction site then where visitors had to step around sacks of cement and duck under scaffolding.

    I imagine the upkeep of road networks is older.

    I view HLLVs similarly…spires of their own kind.

    The Eifle tower was started just a few years later, and was finished by the turn of the century!

    In the micro and nanometers NIST has got it locked down, in the macro and buildings, not so much.
