Following mission failures, NASA restructured its Mars Exploration Program using "Program System Engineering." This approach emphasizes scientific strategies like "follow the water" and exploration tactics such as "seek-in situ-sample" for future Mars missions.

Area of Science:

  • Planetary Science
  • Space Exploration
  • Astrobiology

Background:

  • Loss of Mars Climate Orbiter and Mars Polar Lander in 1999 necessitated a program review.
  • Restructuring of the Mars Surveyor Program into the Mars Exploration Program.
  • Identification of systemic failures in previous mission planning and execution.

Purpose of the Study:

  • To present the process and results of NASA's reexamination of Mars mission failures.
  • To define a new approach termed "Program System Engineering" for future Mars exploration.
  • To outline scientific, technological, and programmatic strategies for the restructured program.

Main Methods:

  • Comprehensive review of past mission failures.
  • Development and implementation of "Program System Engineering" principles.

  • Strategic planning for a new mission architecture and scientific objectives.

    • Main Results:

    • A redefined Mars Exploration Program with enhanced system engineering.
    • Adoption of the scientific strategy "follow the water".
    • Implementation of the exploration strategy "seek--in situ--sample".

    Conclusions:

    • The new "Program System Engineering" approach provides a robust framework for future Mars exploration.
    • The "follow the water" and "seek--in situ--sample" strategies guide scientific inquiry and mission design.
    • International collaborations and telecommunications infrastructure are crucial for mission success.
