OberhettingerSubject: Involve Project Scientists in Critical Decisions Throughout the Project Lifecycle (1999) Abstract: For MCO and MPL, mission scientists w

2、ere not active participants in making critical decisions throughout the mission design and operations phases. Involvement of scientists throughout the project life cycle as full partners in project development and operations makes a significant contribution to overall mission success. Ensure that a

3、detailed mission science plan, tools, and necessary support are in place, and full operations training of the science team (including contingencies) has been completed, prior to any science data collection activities (e.g., planetary encounters, landings, etc.).Description of Driving Event: Compared

4、 to previous projects, the Mars Surveyor Program budgeted significantly less monetary and personnel resources to support the Mars Climate Orbiter (MCO) and Mars Polar Lander (MPL) mission science goals. According to Reference (1), one consequence of this approach was that mission scientists (who had

5、 the most knowledge of Mars, the instruments, and the mission science objectives) were not active participants in making critical decisions throughout the mission design and operations phases. Due to the funding constraints, the science teams were not fully prepared for mission operations supporting

6、 science data collection at Mars. Had either of these missions successfully arrived at Mars, a significant amount of science data could have been lost. In contrast, the successful Mars Pathfinder project had full involvement of the science team from the beginning.Reference(s):1. “Report on Project M

8、sson(s) Learned: 1. A primary measure of mission success is how well a project achieves its science goals. Involvement of scientists throughout the project life cycle makes a significant contribution to overall mission success. Scientists are best able to assess the impact of project decisions on sc
