* Paperback Version - 175 Pages- Printed in COLOR * This is an amazing document that covers the EVA Suit and related technology for exploring the surface of the moon during the ARTEMIS program, Mars and two of its moons, Near Earth Asteroids (NEA), and others. If you like the details and geek out on the engineering, concepts, technology and program design, this is for you! This is well-described, has many, many drawing and photos, and dives deep into the logic and design of every imaginable option that an EVA astronaut would need to work, handle, explore, maneuver and manipulate in these environments. PURPOSE: This EVA Office document captures the xEVA concepts of operations for a wide range of destinations. It focuses on the lunar surface in order to support the Artemis Program, including the science goals driving the missions and the xEVA System capabilities needed to successfully complete the operations. The concepts of operations detailed in this document are intended to inform the development of the xEVA System, including the xEVA Suit, the current design solution for which is the Exploration Extravehicular Mobility Unit (xEMU), and the Vehicle Interface to Suit Equipment (VISE). EVA-EXP-0042 describes the xEVA System operations and the tasks that will be accomplished during missions on the International Space Station (ISS), on Gateway in cislunar orbit, and on the lunar surface as part of the Artemis Phases. It also includes con ops for missions to asteroids and to Mars. This document is intended for Program concept of operations development and Exploration spacesuit suppliers. EVA-EXP-0042 provides the EVA Office standard for conducting EVA in a multitude of environments and locations, and new Programs working with the EVA Office will utilize this con ops as the basis for how EVAs will be conducted, tailored as needed to meet the objectives and goals of that Program. For spacesuit developers, this document provides the basis of what is operationally expected of the spacesuit in a given environment. If there is a conflict between EVA-EXP-0042 and other con ops involving EVA operations, EVA-EXP-0042 takes precedence. An exception is a program specific con ops tailored with support and approval by the EVA Office will take precedence over EVA-EXP-0042.
