Mission Assurance

The Aerospace Corporation defines mission assurance practices and mission type classifications for space systems. The framework categorizes missions by criticality and acceptable risk levels.

Mission Categories

Missions are classified into categories based on:

• Cost of the mission
• Criticality to national security or scientific objectives
• Replaceability — can the mission be re-flown?
• Acceptable risk level

Higher-category missions require more rigorous quality assurance, testing, and review processes.

Key Principles

• Risk-informed decisions — tailor assurance activities to mission criticality
• Independent review — critical missions get independent technical assessment
• Heritage and similarity — leverage proven designs, but verify applicability
• Test as you fly, fly as you test
• Parts and materials control — higher missions require more stringent screening
