    IAG09.B6.3.6 A GLIn-IPSE FROM THE INSIDE OF A SPACE SUIT: WHAT IS IT REALLY LIKE TO TRAIN FOR AN EVA`' Matthew A. Gast United Space Alliance, LLC 600 Gemini, Houston TX, 77058-2783; USA matthew.gast-1 @nasa.gov Sandra K Moore, Ph.D. United Space Alliance, LLC 600 Gemini, Houston TX, 77058-2783 ;USA sandra. k.moore@nasa. gov Abstract The beauty of the view from the office of a spacewalking astronaut gives the impression of simplicity, but few beyond the astronauts, and those who train them, know what it really takes to get there. Extravehicular Activity (EVA) training is an intense process that utilizes NASA's Neutral Buoyancy Laboratory (NBL) to develop a very specific skill set needed to safely construct and maintain the orbiting Intemational Space Station. To qualify for flight assignments, astronauts must demonstrate the ability to work safely and efficiently in the physically demandin g environment of the spacesuit, possess an acute ability to resolve tuiforeseen problems, and implement proper tool protocols to ensure no tools will be lost in space. Through the insights and the lessons learned by actual EVA astronauts and EVA instructors, this paper twill take you on a journey through an astronaut's earliest experiences working in the spacesuit. termed the Extravehicular Mobility Unit (ENI[J), in the underwater training environment of the NBL. This work details an actual Suit Qualification NBL training event, outlines the numerous challenges the astronauts face throughout their initial training, and the various ways they adapt their own abilities to overcome them.

The current NASA spacesuit, the mission [1, 2]. Extravehicular Mobility Unit (EMU), might be thought of as the ‘world’s smallest spacecraft’ and is quite an engineering The EMU is pressurized to 29.6 KPa, using 100% oxygen for achievement. However, the EMU has also led to discomfort and spaceflight and a mixture of nitrogen and oxygen (nitrox) for musculoskeletal injuries, mainly due to the lack of mobility in training. It is made with 14 different layers, and it consists of the pressurized suit that makes moving and operating within the suit challenging. A new musculoskeletal modeling framework is three main components [3], as shown in Figure 1: developed in OpenSim to analyze human-spacesuit interaction and musculoskeletal performance during EVA. Two spacesuits - The Liquid Cooling and Ventilation Garment are considered: the current EMU and NASA’s Mark III (LCVG). This piece of garment made of nylon and spacesuit technology demonstrator.

  • Space Radiation Analysis for the Mark III Spacesuit
    Space Radiation Analysis for the Mark III Spacesuit Bill Atwell1 and Paul Boeder2 Boeing Research & Development, Houston, TX, 77058USA Amy Ross3 NASA Johnson Space Center, Houston, TX, 77058USA The NASA has continued the development of space systems by applying and integrating improved technologies that include safety issues, lightweight materials, and electronics. One such area is extravehicular (EVA) spacesuit development with the most recent Mark III spacesuit. In this paper the Mark III spacesuit is discussed in detail that includes the various components that comprise the spacesuit, materials and their chemical composition that make up the spacesuit, and a discussion of the 3-D CAD model of the Mark III spacesuit. In addition, the male (CAM) and female (CAF) computerized anatomical models are also discussed in detail. We “combined” the spacesuit and the human models, that is, we developed a method of incorporating the human models in the Mark III spacesuit and performed a ray-tracing technique to determine the space radiation shielding distributions for all of the critical body organs. These body organ shielding distributions include the BFO (Blood-Forming Organs), skin, eye, lungs, stomach, and colon, to name a few, for both the male and female. Using models of the trapped (Van Allen) proton and electron environments, radiation exposures were computed for a typical low earth orbit (LEO) EVA mission scenario including the geostationary (GEO) high electron environment. A radiation exposure assessment of these mission scenarios is made to determine whether or not the crew radiation exposure limits are satisfied, and if not, the additional shielding material that would be required to satisfy the crew limits.

  • NASA's Advanced Extra-Vehicular Activity Space Suit Pressure
    48th International Conference on Environmental Systems ICES-2018-273 8-12 July 2018, Albuquerque, New Mexico NASA’s Advanced Extra-vehicular Activity Space Suit Pressure Garment 2018 Status and Development Plan Amy Ross,1 and Richard Rhodes 2 NASA Johnson Space Center, Houston, TX, 77058 Shane McFarland3 NASA Johnson Space Center/MEI, Houston, TX, 77058 This paper presents both near-term and long-term NASA Advanced Extra-vehicular Activity (EVA) Pressure Garment development efforts. The near-term plan discusses the development of pressure garment components for the first design iteration of the International Space Station exploration space suit demonstration configuration, termed the xEMU Demo. The xEMU Demo effort is targeting a 2023-2025 flight demonstration timeframe. The Fiscal Year 2018 (FY18) tasks focus on either the initiation or maturation of component design, depending on the state of development of the components, and the assembly of a suit configuration, termed Z-2.5, that will be used to evaluate changes to the upper torso geometry in a Neutral Buoyancy Laboratory (NBL) test series. The geometry changes, which are being driven by the need to reduce the front-to-back dimension of the advanced extravehicular mobility unit, diverge from a proven shape, such as that of the Mark III Space Suit Technology Demonstrator. The 2018 efforts culminate in the Z-2.5 NBL test. The lessons learned from the Z-2.5 NBL test will inform the xEMU Demo design as the effort moves toward design verification testing and preliminary and critical design reviews. The long-term development plan looks to surface exploration and operations.

  • Extravehicular Mobility Unit
    National Aeronautics and Space Administration Extravehicular Mobility Unit The Extravehicular Mobility Unit (EMU) is comprised mainly of the spacesuit assembly and the Portable Life Support System, which provides breathable air for the astronaut and battery power for the suit’s electrical functions. The EMU accommodates a variety of interchangeable systems that interconnect easily and securely in a single-handed operation for either normal or emergency use. Services Provided • System-level engineering insight into the hardware operational performance and detailed leadership into anomaly resolution. • Real-time mission support for on-orbit activities. • Ground training simulations for training and crew extraction from the Neutral Buoyancy Laboratory and vacuum chamber facilities. • Engineering risk-based guidance for management and sustaining of the EMU hardware and forecast for long-term hardware life-cycle usage. • Developmental proof of concept for changes and additions to the EMU hardware system. Johnson Space Center JOHNSON SPACE CENTER EMU Description Spacesuits are unique in that they are anthropomorphic, customized spacecraft. They must provide environmental protection, mobility, and life support to the crewmember during spacewalks. The suit is modular in design, with many interchangeable parts. The upper torso, lower torso, arms, and gloves are manufactured in three different sizes for the major hard-good components (such as the hard upper torso) and can be assembled for each mission in combinations needed to fit male and female astronauts. This design is cost effective because the suits are reusable and not custom fitted as were Extravehicular Activity (EVA) spacesuits used in previous NASA manned space flight programs. When preparing to work in space, the astronaut goes into the airlock of the International Space Station (ISS) and puts on the following parts of the EMU: • A maximum absorbency garment, which is a modified incontinence diaper.

To prepare for safe and successful execution of the required tasks, astronauts undergo extensive training in the Neutral Buoyancy Lab (NBL), which involves many hours of performing repetitive motions at various orientations, all while wearing a pressurized spacesuit. The current U.S. spacesuit—the Extravehicular Mobility Unit (EMU)—is pressurized to 29.6 kPa (4.3 psi) and requires astronauts to exert a substantial amount of energy in order to move the suit into a desired position. The pressurization of the suit therefore limits human mobility, causes discomfort, and leads to a variety of contact and strain injuries.
