December 18, 2004 marked the fifth anniversary of the launch of NASA's Terra satellite to study the Planet Earth, and the MOPITT (Measurements of Pollution in the Troposphere) instrument's fifth year of successful operation monitoring carbon monoxide in the atmosphere. The MOPITT instrument contains five very different types of mechanisms, all precision engineered to meet the demanding mission requirements. This paper provides an overview of the mechanism designs along with measured long-term on-orbit performance. It gives accounts of on-orbit problems experienced with the mechanisms and describes how they were overcome. The results demonstrate how an appropriately chosen redundancy and fault isolation scheme have been essential to the continuing operation and success of the instrument.
