Direct information about the atmosphere and surface of Mars have been yielded by the two unmanned Viking Missions. Scientific investigations were carried out of the atmospheric composition, the surface elemental abundance, the atmospheric water vapor, meterological conditions and direct tests for organic material and living organisms. The results obtained from 20 June until 11 November 1976 are briefly summarized.
