1965 NASA Apollo SNAP Nuclear Safety Reentry Report Sandia Cornell Aero Lab⁠ For Sale

This original October 1965 technical progress report from Cornell Aeronautical Laboratory (CAL Report No. I23-010-1), prepared for Sandia Corporation, details aerospace nuclear safety investigations into re-entry ablation phenomena and zirconium emissivity during hypersonic tunnel testing. This foundational re-entry thermodynamics research directly supported Sandia's safety validation for SNAP nuclear power units—the generators famously used during the Apollo program to power the Apollo Lunar Surface Experiments Package (ALSEP) on the Moon. Complete with high-magnification electron photomicrograph plates and hypersonic tunnel test logs, this staple-bound contractor document features original "Aerotherm / Acurex Library" cataloging labels, a March 1966 DDC intake stamp, and NASA N66-20885 control numbers, offering a clean, fully legible piece of Cold War space race technical history.
