AIAA Public Review Written 11 February 2025

AIAA S-155, Rendezvous and Proximity Operations (RPO) and On Orbit Servicing (OOS) – Spacecraft Fiducial Markers, has been issued for public review. This document outlines functional, physical, and operational requirements for fiducial markers used in proximity operations, capture and servicing, including manipulation of in-space assets. It is intended to apply to a broad array of RPO/OOS industry participants from spacecraft equipment manufacturers, spacecraft operators, service providers, developers of RPO/OOS simulation, planning and safety tools, and insurers.

AIAA S-158, Prepared Free-Flyer Capture and Release, has also been issued for public review. This document describes best practices, functional requirements, operational requirements, and norms for the design, testing, and operations of prepared Free-Flyer Capture between Servicing Spacecraft and a Client Space Object. The intent is to ensure safe and reliable operations for prepared in-space capture, and to lay the foundation for future standards for prepared capture interfaces.

Public review deadline for both drafts is 14 April 2025. For a copy of the drafts, submission of public review comments, or questions, please contact Nick Tongson .
