Development of the Crew Dragon ECLSS
ICES-2020-333 Development of the Crew Dragon ECLSS Jason Silverman1, Andrew Irby2, and Theodore Agerton3 Space Exploration Technologies, Hawthorne, California, 90250 SpaceX designed the Crew Dragon spacecraft to be the safest ever flown and to restore the ability of the United States to launch astronauts. One of the key systems required for human flight is the Environmental Control and Life Support System (ECLSS), which was designed to work in concert with the spacesuit and spacecraft. The tight coupling of many subsystems combined with an emphasis on simplicity and fault tolerance created unique challenges and opportunities for the design team. During the development of the crew ECLSS, the Dragon 1 cargo spacecraft flew with a simple ECLSS for animals, providing an opportunity for technology development and the early characterization of system-level behavior. As the ECLSS design matured a series of tests were conducted, including with humans in a prototype capsule in November 2016, the Demo-1 test flight to the ISS in March 2019, and human-in-the-loop ground testing in the Demo-2 capsule in January 2020 before the same vehicle performs a crewed test flight. This paper describes the design and operations of the ECLSS, the development process, and the lessons learned.

INTRODUCTION This Study of Reentry Vehicle (RV)
INTRODUCTION This study of Reentry Vehicle (RV) systems and their associated operations was conducted for the Department of Transportation/Office of Commercial Space Transportation. The purpose of the study was to investigate and present an overview of reentry vehicle systems and to identify differences in mission requirements and operations. This includes reentry vehicle system background, system design considerations, description of past/present/future reentry systems, and hazards associated with reentry vehicles that attain orbit, reenter, and are recovered. A general literature search that included the OCST data base, NASA, Air Force, and other technical libraries and personal contact with various government or private industry organizations knowledgeable in reentry system vehicles was performed. A reference page is provided at the end of this report. A history of early manned reentry vehicle launches is shown in Appendix I. A listing of some of the agencies and companies found to be most knowledgeable in the reentry vehicle area is provided in Appendix II. The following sections provide more detailed information on reentry system vehicles. A. Background - The development of reentry vehicles began in the late 1950's due to the need for Department of Defense and Central Intelligence Agency photo reconnaissance of Soviet ICBM sites. NASA has also been involved in the use of reentry vehicles since the early 1960's, including manned space programs Mercury, Gemini and Apollo. The following sections describe the evolution of reentry system development in the United States and foreign countries: 1. Discoverer1 - The Discoverer program was of major importance because it provided a vehicle for testing orbital maneuvering capability and reentry techniques and it played a large role in enabling the first United States manned space flights to be conducted in Project Mercury. -
Air Transport
The History of Air Transport KOSTAS IATROU Dedicated to my wife Evgenia and my sons George and Yianni Copyright © 2020: Kostas Iatrou First Edition: July 2020 Published by: Hermes – Air Transport Organisation Graphic Design – Layout: Sophia Darviris Material (either in whole or in part) from this publication may not be published, photocopied, rewritten, transferred through any electronical or other means, without prior permission by the publisher. Preface ommercial aviation recently celebrated its first centennial. Over the more than 100 years since the first Ctake off, aviation has witnessed challenges and changes that have made it a critical component of mod- ern societies. Most importantly, air transport brings humans closer together, promoting peace and harmo- ny through connectivity and social exchange. A key role for Hermes Air Transport Organisation is to contribute to the development, progress and promo- tion of air transport at the global level. This would not be possible without knowing the history and evolu- tion of the industry. Once a luxury service, affordable to only a few, aviation has evolved to become accessible to billions of peo- ple. But how did this evolution occur? This book provides an updated timeline of the key moments of air transport. It is based on the first aviation history book Hermes published in 2014 in partnership with ICAO, ACI, CANSO & IATA. I would like to express my appreciation to Professor Martin Dresner, Chair of the Hermes Report Committee, for his important role in editing the contents of the book. I would also like to thank Hermes members and partners who have helped to make Hermes a key organisa- tion in the air transport field. -
