The spacecraft was capable of studying circumlunar space, the lunar gravitational field, and the chemical composition of lunar rocks. It was also capable of providing lunar surface photography. The missions was a failure, however, after completing 86 communications sessions and 52 orbits of the Moon at various inclinations and altitudes, the spacecraft impacted the lunar surface on July 21, 1969.
