To me one of the major successes of the fiorst manned landing on the moon, was the return of a large amount of lunar rock samples, as well as the spectacular imagery of that forbidding lunar landscape (which I love immensly) & the deployemnt of vital scientific equipment, i.e seismometer, Corner Reflector, etc.
Interesting sample here: Lunar Basalt 10049 returned by Apollo 11.
This is physical evidence of volcanic processes of having happened on the moon. Whilst various US & Russian, then Soviet unmanned orbiters had photographed volcanic domes, lava tubes etc from orbit, this was actual hard physical evidence to back up those earlier findings.
Sample 10046. Various moon rocks returned by Apollo 11.
Sample 10072, 442 gram Vesicular Basalt bought back by Apollo 11.
Various tiny fragments here bought back by Apollo 11. The grid spacing is 2mm.
The fragments incluide volcanic basalt, resolidified impact melt, breccias, anorthosites & glass sphericals.
It's interesting that anorthosites were found in Mare Tranquilitatis as anorthosites are usually found in the highlands, such as Apollo 16 landing site in Descartes. Peraps they were blated here from distant highland impacts???
A One Quarter of One MM (0.25mm) glass spherule, which itself sports two microscopic impact craters, returned with Apollo 11. Some of these seems to suggest an increase in lunar impact rate approx 500 million years ago. Perhaps Wayne may know more about this (Wayne no doubt does know much more about this than me).
I will be starting another thread dealing with lunar samples bought back from Apollo 12 to Apollo 17 but this thread is just for Apollo 11.
