NASA Procedural Requirements

NPR 8079.1 Effective Date: June 27, 2023 Expiration Date: June 27, 2028

Subject: NASA Spacecraft Conjunction Analysis and Collision Avoidance for Space Environment Protection

Responsible Office: Office of the Chief Engineer

Appendix E. Conjunction Assessment Operations Implementation Agreement (CAOIA) Elements

E.1 The CAOIA documents the operational processes that the project implements to protect the space environment. (See Section 3.3.) Operational requirements are detailed in chapters 4 and 5 of this directive. The CAOIA includes processes for the conjunction assessment screening, conjunction risk assessment, and conjunction mitigation steps.

E.2 Project managers obtain the most recent template for the CAOIA from CARA. The project manager and CARA coordinate the specific contents of the CAOIA template depending on specific mission characteristics.

E.3 A notional table of contents for a maneuverable mission is provided below.
