The Mariner 6 and 7 Pictures of Mars

Book excerpt: "The present volume presents the results of the Mariner VI and VII missions, in a more finished form that has been issued hitherto. Greatest interest attaches to the 200-odd television images which the world first viewed in their crude form as they were received on Earth. To most fully utilize this television data, NASA has sponsored extensive post-flyby computer processing and analysis of these pictures. The purpose of this book is to make available high-quality reproductions of the final, computer-processed pictures. The text serves only to explain the genesis and unique characteristics of the pictures, to point out interesting features in them, and to provide some indication of their significance in the history of Mars investigations. Detailed analysis has been avoided in this volume."--p. v, vii.
