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.
"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
The uncertainty of science: Male mice who spent thirty-five days on ISS but within a centrifuge that created 1 g of artificial gravity apparently experienced no damage to their ability to reproduce.
This project team developed a habitat cage unit (HCU) capable of being installed in the Centrifuge-equipped Biological Experiment Facility (CBEF) on the ISS. The mice were placed under artificial gravity or microgravity (by centrifugation). After their return to Earth, they were compared with a “ground control” raised on the ground for the same 35-day period. (Fig.1)
The joint team found that:  The sperm production ability and the sperm fertilizing ability of the mice returned to Earth were normal, compared to the ground control and,  offspring of the mice sent to outer space was healthy and there were no effects on their reproduction ability from their parents’ stay in outer space.
While this study suggests that some form of artificial gravity can possible mitigate some of the risks to reproduction in space, there are so many unknowns that it at this point it leaves more questions than it answers.
I could go on. I almost wish they had done this experiment first in zero gravity, to see its effects, before proceeding to an artificial gravity environment.
Nonetheless, these results do suggest that reproduction in space will be possible, as long as an artificial gravity of some kind is provided.
My July fund-raiser for Behind the Black is now over. The support from my readers was unprecedented, making this July campaign the best ever, twice over. What a marvelous way to celebrate the website's tenth anniversary!
Thank you! The number of donations in July, and continuing now at the beginning of August, is too many for me to thank you all personally. Please forgive me by accepting my thank you here, in public, on the website.
If you did not donate or subscribe in July and still wish to, note that the tip jar remains available year round.
