Mars Life - Viking Mission

NASA's Viking Mission to Mars was composed of two spacecraft, Viking 1 and Viking 2, each consisting of an orbiter and a lander. The primary mission objectives were to obtain high resolution images of the Martian surface, characterize the structure and composition of the atmosphere and surface, and search for evidence of life. Students begin by reviewing their criteria for defining the presence of life. They read the descriptions of the Viking Lander biology experiments and use their knowledge of life processes to determine the principles by which each of the instruments looked for signs of life. Teams will answer the questions on their worksheets (with the help of the fact sheet provided) and then decide to focus on one experiment, which they will explain to the rest of the class.
