The book has graphs, diagrams, it has 126 pages (see pictures). It is in complete lightly used condition, genuine original from Oct-1970 (see pictures). The cover has light wear, the pages are clean (see pictures). This old original NASA Issued JPL Report comes as shown in the pictures. Should be of interest vintage 1960s space exploration history-accessories-memorabilia & vintage NASA / satellite / spacecraft related collectors. Take a look at the pictures & e-mail me with questions. Buyer pays $4.90 USA shipping. I will combine the shipping for multiple auction buyers.
