Live Dogs and Dead Vikings
The Mars Viking probes of the mid 1970s were the culmination of the early years of planetary exploration. A major part of their mission was to look for evidence of life on the planet; they found none. Despite this there is still some dissent amongst the original investigators as to what Viking discovered.
Students are provided with a description of the Viking life sciences experiments and are encouraged to compare the approach to that taken by Beagle 2. In addition students can use the material to probe deeper into the capabilities and limitations of the scientific method.
