Space programs summary no. 37-43, volume 1 for the period 1 November - 31 December 1966. The lunar program
A bimonthly technical progress report on NASA's lunar program, issued in 1967 for engineers and program staff tracking Surveyor spacecraft hardware and test work. Illustrations are coarse-screened laboratory photographs of test rigs, tubing and valve assemblies and a welded structural test frame, paired with clean line drawings such as a hatched cross-section of a reversible valve seat; useful for halftone grain, industrial clutter, and technical section-drawing conventions.
