Abstract

Following a public hearing format, this case study allows students to explore the scientific and public policy issues surrounding the advisability of a return mission to Mars for further sampling and, more generally, the question of whether or not there is life on that planet. The case was developed for a non-science majors course called “Great Discoveries in Science” and serves to illustrate the scientific method and the importance of interdisciplinary efforts in scientific research.


Objectives

  • Examine how the scientific method is used to develop a scientific hypothesis, and how new information is used to reevaluate an existing hypothesis.
  • Illustrate the importance of interdisciplinary efforts in scientific research.
  • Critically evaluate interpretations of experimental data through the labeled release and GC/MS experiments on Viking.
  • Define the criteria needed to establish whether something is living.
  • Raise general awareness of the planned Mars Sample Return Mission.
  • Undertsand how public hearings are used to shape science policy in the United States.
  • Examine cost/benefit analysis and the element of risk in formulating public policy.
  • Develop possible alternatives to the Mars Sample Return Mission as currently planned.
