Luna 19 (a.k.a. Lunik 19) (E-8-LS series), was an uncrewed space mission of the Luna program. Luna 19 extended the systematic study of lunar gravitational fields and location of mascons (mass concentrations). It also studied the lunar radiation environment, the gamma-active lunar surface, and the solar wind. Photographic coverage via a television system was also obtained.
