AIAA Public Review

FROM THE INSTITUTE
AIAA S-159, On-Orbit Servicing Power and Data Interfaces, has been issued for public review. This document provides best practices, functional requirements, and norms associated with the power and data interfaces between a Servicing Spacecraft and a Client Space Object. The intent is to provide guidance to developers and operators of both the Servicing Spacecraft and the Client Space Object. The public review deadline is 30 June 2026. For a copy of the draft, submission of public review comments, or questions, please contact Michele Dominiak at [email protected].

AIAA Draft Standard S-110A Undergoing 2nd Public Review

The draft standard AIAA S-110A (revision of AIAA S-110-2005), Space Systems—Structures, Structural Items, and Pressurized Structures is undergoing a second public review. The AIAA Structures Committee on Standards is responsible for developing this revised draft standard. The document establishes baseline structural requirements for the design, test, qualification, and acceptance of spaceflight structures and pressurized structures. To obtain a copy for review, please contact Nick Tongson. Public review deadline: 29 August 2025.

EASA Publishes Noise Standards for EVOTLs

Aviation International News reports that EASA “has published what it claims are the world’s first proposed noise certification standards for eVTOLs.” The proposals, known as the Environmental Protection Technical Specifications (EPTS), “are applicable to eVTOL vehicles powered by multiple vertical, non-tilting, evenly distributed rotors.” EASA says that the proposed specifications “are intended to fill a regulatory gap and use the internationally harmonized noise certification standards for heavy helicopters” as a starting point while it “collects more noise data from specific eVTOL designs through certification projects.” In addition, a hover noise level “has been developed to aid in the assessment of flight operations in the vicinity of vertiports.”
