Major Professor: Keith Koenig Title of Study: Human systems integration of an extravehicular activity space suit augmented reality display system Pages in Study 38 Candidate for Degree of Master of Science During an extravehicular activity (EVA), the role of an astronaut involves a multitude of complex tasks. Whether that task is a science experiment aboard the International Space Station, or traversing extraterrestrial terrain – attention, communication, and instruction are essential. As an aid, augmented reality (AR) can portray suit informatics and procedures within line-of-sight while minimizing attentional loss. Currently, there exists little research highlighting the human systems considerations to qualify AR systems for space suit applications. This study quantifies user interface (UI) and human performance measures for an AR prototype on the Mark III space suit. For user testing, 21 military pilots and personnel (11 men, 10 women) evaluated UI search tasks and completed a series of AR-instructed EVA dexterity tasks in an elevated luminosity, background clutter, and workload scenario. UI results suggest correlations for readability and usability; whereas, human performance results provide situational awareness, workload, and task performance data. DEDICATION I dedicate this Master’s Thesis to my father, Dr. Amal K. Mitra, mother, Ratna Mitra, and brother, Amlan Mitra.

Today, large-scale space habitation, and the opportunity to take advantage of the vast resources and possibilities of outer space, remains more in the realm of speculation than reality. We have experienced fifteen years of continuous space habitation and construction, with another seven years scheduled. Yet we have still not been able to take major steps towards commercial and industrial space development, which is usually the most-cited reason for establishing orbital colonies. This is mainly due to the prohibitively high cost, even today. In this situation, we cannot easily afford the luxury of testing how such systems could eventually work in space. This leaves us looking for analogous situations. While some scientists have sought this in the mountains of Hawaii, this does not tell the full story. We are unable to properly fathom or test how a large-scale industrial and tourism operation, as it is expected will eventually exist on-orbit, on Earth. This led us to the idea of building an oceanic base. The ocean is, in many ways, similar to free space. Large swathes of it remain unexplored. There are unrealised commercial opportunities. There are hostile yet exciting environments. Creating basic life support and pressure-containing structures are challenging.

    Concept Study of a Cislunar Outpost Architecture and Associated Elements that Enable a Path to Mars Presented by: Timothy Cichan Lockheed Martin Space [email protected] Mike Drever Lockheed Martin Space [email protected] Franco Fenoglio Thales Alenia Space Italy [email protected] Willian D. Pratt Lockheed Martin Space [email protected] Josh Hopkins Lockheed Martin Space [email protected] September 2016 © 2014 Lockheed Martin Corporation Abstract During the course of human space exploration, astronauts have travelled all the way to the Moon on short flights and have logged missions of a year or more of continuous time on board Mir and the International Space Station (ISS), close to Earth. However, if the long term goal of space exploration is to land humans on the surface of Mars, NASA needs precursor missions that combine operating for very long durations and great distances. This will allow astronauts to learn how to work in deep space for months at a time and address many of the risks associated with a Mars mission lasting over 1,000 days in deep space, such as the inability to abort home or resupply in an emergency. A facility placed in an orbit in the vicinity of the Moon, called a Deep Space Transit Habitat (DSTH), is an ideal place to gain experience operating in deep space. This next generation of in-space habitation will be evolvable, flexible, and modular. It will allow astronauts to demonstrate they can operate for months at a time beyond Low Earth Orbit (LEO). The DSTH can also be an international collaboration, with partnering nations contributing elements and major subsystems, based on their expertise.

  • Jenkins 2000 AIRLOCK & CONNECTIVE TUNNEL DESIGN
    Jenkins_2000 AIRLOCK & CONNECTIVE TUNNEL DESIGN AND AIR MAINTENANCE STRATEGIES FOR MARS HABITAT AND EARTH ANALOG SITES Jessica Jenkins* ABSTRACT For a manned mission to Mars, there are numerous systems that must be designed for humans to live safely with all of their basic needs met at all times. Among the most important aspects will be the retention of suitable pressure and breathable air to sustain life. Also, due to the corrosive nature of the Martian dust, highly advanced airlock systems including airshowers and HEPA filters must be in place so that the interior of the habitat and necessary equipment is protected from any significant damage. There are multiple current airlocks that are used in different situations, which could be modified for use on Mars. The same is true of connecting tunnels to link different habitat modules. In our proposed Mars Analog Challenge, many of the airlock designs and procedures could be tested under simulated conditions to obtain further information without actually putting people at risk. Other benefits of a long-term study would be to test how the procedures affect air maintenance and whether they need to be modified prior to their implementation on Mars. INTRODUCTION One of the most important factors in the Mars Habitat design involves maintaining the air pressure within the habitat. Preservation of breathable air will be an extremely vital part of the mission, as very little can be found in situ. Since Mars surface expeditions will be of such long duration, it is imperative that the airlock designs incorporate innovative air maintenance strategies. For our proposed Earth Analog Site competition, many of the components of these designs can be tested, as can the procedures required for long-duration habitation on Mars.
