MARS SCIENTIFIC MODEL.
MICHAUX, C.M., and R.L. NEWBURN. Mars Scientific Model. JPL Document No. 606-1. Pasadena, CA: JPL, March 1, 1972.
11 x 9 inches. Several folding plates, some printed in color with transparent overlays. Folding charts in pocket at front. Tabbed, punched, and in original vinyl 3-ring binder.
A loose-leaf update of the work first published in 1968. "Our intent in the new edition of this document had been to present a summary of knowledge about Mars shortly before the time of arrival of Mariner 9" (Preface). The title on the binder states "Volume 1," but the work appears complete and we have not been able to locate a second volume in institutions.
