1. International Deep Space Interoperability Standards - https://www.internationaldeepspacestandards.com/

1.1. International External Robotic Interface Interoperability Standards (IERIIS)

The purpose of the IERIIS is to provide a set of common design parameters to allow module, visiting vehicle, and on-orbit relocatable or replaceable unit (ORU) providers to architect and design elements which are compatible with an external robotic system, and vice versa for human exploration and associated interfaces in deep space environments. The focus of this document version is on cislunar space missions, specifically crewed orbital platforms. Future revisions of the document will incorporate additional deep space missions. This standard leverages International Space Station (ISS) robotic interface heritage and lessons learned, as well as related technology development activities.

Similar to terrestrial robotic interface standards, the scope of this document is focused on standard common mounting interfaces for robotic manipulator fixtures; it does not define the fixtures.

This standard similarly does not address internal robotic compatible systems, vehicle to vehicle berthing only interfaces (e.g. ISS Common Berthing Mechanism (CBM)), or vehicle to vehicle berthing compatible docking interfaces (e.g. berthing compatible International Docking System Standard (IDSS) implementation (IDSS-B)).


1.2. International Thermal System Interoperability Standards (ITSIS)

All spacecraft require a thermal management system to maintain a tolerable thermal environment for the spacecraft crew and/or equipment. The purpose of this document is to state standards for when common fluids are employed in active external and internal coolant loops and agreed-to requirements for coldplates that interface directly to those coolant loops. Future revisions of the document will incorporate any additional content for deep space missions that is not already included. This standard supports reliability and commonality for cooling systems that work across elements, when there is agreement to utilize common coolant(s). This document also provides basic, common design parameters to allow developers to independently develop and/or provide compatible coldplates.
