July 11, 2017 Zimmerman Space Show podcast
You can now listen to my two-hour appearance on the Space Show, posted here as a podcast available for download.
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

Referencing the Chinese experiment’s with manipulating exposure to light and potential application to Moon based settlement.
Circadian rhythm’s are ubiquitous to most all life on Earth, and they generally follow a 24 hour(ish) cycle. Exposure to sunlight is heavily implicated in controlling this, although cave-dwelling animals also display certain circadian cycles. (Gravity as well, is implicated.)
We humans in particular are creatures of a 24 hour day/night cycle, it’s hard wired into the equipment.
For the Moon– you are going to need lighting that replicates the spectrum & the day/night cycle of Earth.
Humans can tolerate extremes of light/dark cycles (as long as sleep/awake, remains steady) but performance is sacrificed in the short term, and longer term people can get clinically impaired. (a small percentage, but it’s not zero.)
-If you want to drive people literally nuts– manipulate their sleep/awake schedule and deprive them of high-quality lighting.
Wayne: You miss the point, which is what I think the Chinese actually wanted. They really aren’t testing whether humans can deal with doing without sunlight for a period of time. The bigger problem is engineering the facility so that it can function adequately during those long sunless periods. This is not a simple thing, as the temperature swings alone on the Moon can cross hundreds of degrees.
