A comment by @Hobbes on the question How did Apollo-12 manage to land next to Surveyor-3? First “Space-Tourists”? points out that the "souvenirs" removed and retrieved from the Surveyor-3 lander by the astronauts and returned to Earth were studied for "the effects of long-term exposure to space" on moon exploration equipment.
This was important not only for basic science, but for planning for equipment to be left on the moon by subsequent Apollo missions and further space exploration as well. The components had been exposed to the lunar space environment and solar radiation for 31 and 16 months, respectively.
Is there any discussion or reports of "What was learned from study of Surveyor-3's components, retrieved and returned to Earth by Apollo-12?"
