Very appealing pair of staple-bound Apollo 15 manuals prepared for NASA: a manual entitled "Apollo 15, Lunar Trajectory Notes," dated June 30, 1971, 215 pages, 8 x 10.5, providing general information about the design of the lunar trajectories, with three sections presenting a description of the Apollo 15 mission, the earth-moon-sun relationship, and information for a typical lunar mission, such as trajectory planning, requirements, and restrictions; the second manual is entitled "Apollo 15, Index of 70mm Photographs," dated January 12, 1972, 350 pages, 8 x 10.5, which features descriptions for all numbered 70mm photographs assigned to the Apollo 15 mission, with photographs in first section listed in sequence by NASA photo numbers, and lunar surface and orbital cross-indexed in subsequent sections. In overall very good to fine condition, with some slight creasing and staining to covers.
