The Moon gets pounded more than expected


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.

 
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

The uncertainty of science: A close review of Lunar Reconnaissance Orbiter (LRO) images now suggests that asteroid impacts occur 33% more than previously estimated.

The research also suggests that the lunar surface gets rechurned faster than previously thought, which could force planetary scientists to adjust their solar system aging system that is based on crater counts.

The article makes the entirely false claim that this increased rate of impacts poses a threat to lunar colonies, probably in an effort by these scientists to lobby for funds for a combined lunar orbiter-lander mission. The first lunar colonies will likely be placed below ground, partly to protect them from the harsh lunar environment as well as from radiation, and partly because that will be the easiest way to build those colonies. The impacts being measured here are all relatively small, and would not threaten these underground colonies.

Readers!

    From the article: “Along with the fresh craters, Speyerer’s team found more than 47,000 ‘splotches’, formed when material gets kicked up by the main impact and rains down — sometimes tens of kilometres away. … The chances of a lunar base being nailed by a direct meteorite hit are relatively small, but the splattered material could pose a hazard.”

    My calculation, assuming an average of 10 kilometer radius for the “splash zone” of impact material “rain,” is that we could expect 4,000 years to pass before any given square kilometer is affected by this “rain.”

    What the ill effects of this “rain” may be is yet another question.
