Keith's note: Have a look at "The Lunar Orbiter Meteoroid Experiments -Description and Results from Five Spacecraft" online at Infoeach - in China. China has their own version of NTRS - just in case NASA shuts it down again to check and see if China is getting access that it should not have. This paper was not available on NTRS to Americans for months even though it deals with spacecraft that flew in the 1960s. Feel safer now?
