A number of American space exploration "firsts" were launched from CCAFS, including the first U.S. Earth satellite (1958), first U.S. astronaut (1961), first U.S. astronaut in orbit (1962), first two-man U.S. spacecraft (1965), first U.S. unmanned lunar landing (1966), and first three-man U.S. spacecraft (1968). It was also the launch site for all of the first spacecraft to (separately) fly past each of the planets in the Solar System (1962–1977), the first spacecraft to orbit Mars (1971) and roam its surface (1996), the first American spacecraft to orbit and land on Venus (1978), the first spacecraft to orbit Saturn (2004), and to orbit Mercury (2011), and the first spacecraft to leave the Solar System (1977).
