Shashwat Goel & Ankita Phulia Anastasi 2032 Table of Contents Section Page Number 0 Introduction 2 1 Basic Requirements 4 2 Structural Design 15 3 Operations 31 4 Human Factors 54 5 Business 65 6 Bibliography 80 Fletchel Constructors 1 Shashwat Goel & Ankita Phulia Anastasi 2032 0 Introduction What is an underwater base doing in a space settlement design competition? 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
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. -

72 PROTEIN PHOSPHORYLATION AND CELLULAR REGULATION, I Nobel Lecture, December 8, 1992 by E DWIN G. K R E B S Departments of Pharmacology and Biochemistry, School of Medicine, SL-15, University of Washington, Seattle, WA 98195, USA. INTRODUCTION This presentation and the one to be given immediately thereafter will be concerned with the reversible phosphorylation of proteins and the role of this process in biological regulation. In addition to discussing our own early contributions to this field, Ed Fischer and I will describe some of the developments that have occurred subsequently. These developments have led to the realization that protein phosphorylation constitutes a major mechanism by which cellular processes are controlled. My own remarks will review the historical background that provided the setting in which our joint work was carried out in the 1950s and early 1960s. Then I’ll turn to a discussion of this work itself, to be followed by comments on the cyclic AMP-dependent protein kinase. Finally I will talk about the intracellular transmission of hormone and growth factor signals through protein kinase cascades. BACKGROUND By 1940, which is the year in which I entered medical school at Washington University in St Louis, it was well established that the breakdown of glyco- gen in skeletal muscle and other types of cells occurs by the process of phosphorolysis, catalyzed by the enzyme phosphorylase (for review, see ref. 1). Carl Cori was Professor and Chairman of the Department of Pharmacol- ogy at Washington University, when I started my training there, but he was soon to take over the Department of Biological Chemistry. -

Gerty Theresa Cori
NATIONAL ACADEMY OF SCIENCES G ERTY THERESA C ORI 1896—1957 A Biographical Memoir by J OSEPH LARNER Any opinions expressed in this memoir are those of the author(s) and do not necessarily reflect the views of the National Academy of Sciences. Biographical Memoir COPYRIGHT 1992 NATIONAL ACADEMY OF SCIENCES WASHINGTON D.C. GERTY THERESA CORI August 8, 1896-October 26, 1957 BY JOSEPH LARNER ERTY AND CARL CORI'S most significant contributions Gwere the establishment of the cycle of carbohydrates known as "the Cori Cycle," the isolation of glucose 1-phos- phate, and the discovery of phosphorylase and phospho- glucomutase. These discoveries established the enzymatic pathways of glycogenolysis and glycolysis. In glycogen metabolism, Gerty Cori pioneered in the discovery of the debranching enzyme amylo-l,6-glucosidase and its use in the elucidation of glycogen structure by se- rial enzymatic degradation. This pioneering work led to the elucidation of the enzymatic defects in the glycogen storage diseases. Her studies, therefore, extended funda- mental scientific discoveries into the clinical arena, most particularly in the field of pediatrics, her original area of clinical interest and specialization. Gerty Theresa Radnitz was born on August 8, 1896, in Prague, at that time part of the Austro-Hungarian empire. Otto Radnitz, her father, was director general of a sugar refinery in Bohemia. Her mother's brother was professor of pediatrics at the University of Prague. Gerty studied at home until the age of ten, when she went to a girls' prepa- ratory school, from which she graduated in 1912. In 1914, after passing her final examination (matura) at the Tetschen 111 112 BIOGRAPHICAL MEMOIRS Real Gymnasium, she enrolled as a medical student at the Carl Ferdinand University, the German university of Prague. -

They also have maintained a great fear of the unknown and very few wished to actually go under the surface. In the not too distant past, they had a morbid fear and were deeply frightened of what they might find. Only three out of one hundred old-time sailors could swim because they had no love of water.
