Mariner to Probe Viking Landing Sites
Pasadena, Calif.—Martian sites with a maximum possibility of harboring some form of life are being surveyed for the Viking lander program by the Mariner 9 spacecraft in its current exploration of the planet. Earlier it was widely believed in the scientific community that Mars was essentially a dead body, exhibiting little variation in structure, topography and climate, and therefore, less premium needed to be placed on Viking lander site selection because all areas would be of about equal interest.
