After launch, Luna 2 traveled toward the Moon and released several instruments and scientific packages. It carried magnetometers, radiation detectors, and micrometeoroid detectors, among other equipment, to investigate the space environment between Earth and the Moon. The spacecraft also carried spherical pennants bearing the Soviet emblem, which were designed to reach the lunar surface with the probe.

Luna 2 impacted near the boundary between Mare Imbrium (Sea of Rains) and Mare Serenitatis (Sea of Serenity) at approximately 21:02 UT on September 14. The impact confirmed that the Moon had no significant global magnetic field and provided measurements of the lunar environment and solar wind.
