O-Strand Mission Computers Practice Test 2026 – Complete Exam Prep Resource

In a dual Mission Computer setup, the task of declaring Mission Accomplishment is assigned to the second computer to provide independent validation and a clean handoff. MC2 monitors all the required criteria, confirms that every critical step is finished, and triggers the end-of-mission sequence—logging the final status and notifying ground control as needed. This separation from the primary computer, which handles real-time control and execution, helps prevent a single point of failure from causing an uncertain or unsafe termination. So the second Mission Computer is the one responsible for Mission Accomplishment.
