Lunar Origin Discussion Continues

 
 
 
 
PSI Senior Scientist William Hartmann published a paper, "The giant impact hypothesis: past, present (and future?)” in the Sept. 13 issue of the Philosophical Transactions of the Royal Society (London). The issue is devoted to papers from last fall's Lunar Origin conference hosted by London’s Royal Society.
 
His paper discusses the giant impact hypothesis for lunar origin, presented by Hartmann and Don Davis in a 1974 conference and first published in Icarus in 1975.
 
Philosophical Transactions of the Royal Society was started in 1665 and is the oldest scientific journal in the world.
 
Hartmann also was invited to provide the cover painting for the issue.  
 
Above, Hartmann’s cover art shows a visualization of the giant Moon-forming impact about one hour after the initial collision, as based on computer modeling.
