Mariner 6 and 7 Television Pictures: Preliminary Analysis


Before the space era, Mars was thought to be like the earth; after Mariner 4, Mars seemed to be like the moon; Mariners 6 and 7 have shown Mars to have its own distinctive features, unknown elsewhere within the solar system.

Additional Information

© 1969 American Association for the Advancement of Science. We gratefully acknowledge the support and encouragement of the National Aeronautics and Space Administration. An undertaking as complex as that of Mariners 6 and 7 rests upon a broad base of facilities, technical staff, experience, and management, and requires not only money but much individual and team effort to be brought to a successful conclusion. It is impossible to know, much less to acknowledge, the important roles played by hundreds of individuals. We are deeply appreciative of the support and efforts of H. M. Schurmeier and the entire Mariner 1969 project staff. With respect to the television system, responsibility for the design, assembly, testing, calibration, flight operation, and picture data processing lay with the Jet Propulsion Laboratory. We gratefully acknowledge the contributions of G. M. Smith, D. G. Montgomery, M. C. Clary, L. A. Adams, F. P. Landauer, C. C. LaBaw, T. C. Rindfleisch, and J. A. Dunne in these areas. L. Malling, J. D. Allen, and R. K. Sloan made important early contributions. We are indebted to V. C. Clarke, C. E. Kohlhase, R. Miles, and E. Greenberg for their help in exploiting the flexibility of the spacecraft to achieve maximum return of pictorial data. We are especially appreciative of the broad and creative efforts of G. E. Danielson as Experiment Representative. The able collaborative contributions of J. C. Robinson in comparing Mariner pictures with Earth-based photographs and of L. A. Soderblom and J. A. Cutts in measuring craters are gratefully acknowledged.
