NASA NTRS1973

Science sequence design

The activities of the following members of the Navigation Team are recorded: the Science Sequence Design Group, responsible for preparing the final science sequence designs; the Advanced Sequence Planning Group, responsible for sequence planning; and the Science Recommendation Team (SRT) representatives, responsible for conducting the necessary sequence design interfaces with the teams during the mission. The interface task included science support in both advance planning and daily operations. Science sequences designed during the mission are also discussed.

NASA NTRS1972

Mariner Mars 1971 adaptive mission planning.

A formal mission-planning process was developed for the Mariner Mars 1971 missions to allow large-scale mission-plan changes based upon flight experience. A modular approach was taken to the definition of requirements and constraints for elements of the mission. A set of rules for combining these modules was established. The concept of a standard mission day was developed in order to provide a consistent time framework for operations. The resulting process allowed for major mission revisions after the failure of Mariner 8 and again after a dust storm had obscured Mars. It allowed adaptive science planning on a short-term turnaround basis throughout the mission.
