Abstract
The year 1965 was a momentous one in the unmanned exploration of Mars. The U.S. spacecraft Mariner IV obtained 21 close-up pictures of that planet and successfully returned these and other scientific data to Earth. Earlier in the year, a larger Soviet spacecraft, Zond II, failed in flight after completing 61 percent of the journey-almost an exact repetition of the failure of the earlier Soviet spacecraft Mars I, launched 1 November 1962.
