Goals: Luna 14's primary goal was to test communications systems in support of the Soviet effort to send cosmonauts to the Moon. It was also to provide data for studies of various phenomena in the lunar environment.

Accomplishments: In addition to testing the communications systems, it provided data for studies of the lunar gravitational field, the solar wind, cosmic rays, lunar motion, and the interaction of the Earth and lunar masses.

Luna 14 successfully entered lunar orbit at 19:25 UT on 10 April 1968. Initial orbital parameters were 160 x 870 km at 42 degrees inclination.

The primary goal of the flight was to test communications systems in support of the N1-L3 piloted lunar landing project. Ground tracking of the spacecraft's orbit also allowed controllers to accurately map lunar gravitational anomalies in order to predict trajectories of future lunar missions such as those of the LOK and LK lunar-landing vehicles.

Luna 14 also carried scientific instruments to study cosmic rays and charged particles from the sun, although few details have been revealed.
