A Plan for Planetary Exploration in the 1970's 680378
The United States initiated man's first close-up observations of the planets, Venus and Mars, with successful Mariner missions in 1962, 1964-1965, and in 1967. With the rapid development of rockets, communications, technologies, scientific instruments, and space-flight operations capabilities, we are now in a position to plan a planetary program for the 1970s with specific goals and objectives. Such a plan is outlined, including goals and objectives for the effort, some of the experiments to be performed, the phasing of missions, some indication of alternate possibilities, and the desirable advances in technologies required. For basic reference in discussing characteristics of the 1970 plans, Mariner spacecraft and missions of the 1960s will be reviewed.
