Phobos 1 launched

PhobosThe Soviet Union launches the first of two unmanned Phobos space probes, designed to investigate the largest of Mars’ two asteroid-like moons and deliver a lander to analyze that moon’s surface. With multiple nations pitching in resources to help the mission succeed, including the United States, the Phobos program is intended to be the definitive Mars exploration program of the 1980s, as well as the debut of a new Soviet interplanetary vehicle to take over from the Zond/Venera design in use since the 1960s.
