In the early 1990s, NASA Goddard Space Flight Center started researching and developing autonomous and autonomic ground and spacecraft control systems for future NASA missions. This research started by experimenting with and developing expert systems to automate ground station software and reduce the number of people needed to control a spacecraft. This was followed by research into agent-based technology to develop autonomous ground c- trol and spacecraft. Research into this area has now evolved into using the concepts of autonomic systems to make future space missions self-managing and giving them a high degree of survivability in the harsh environments in which they operate. This book describes much of the results of this research. In addition, it aimstodiscusstheneededsoftwaretomakefutureNASAspacemissionsmore completelyautonomousandautonomic.Thecoreofthesoftwareforthesenew missions has been written for other applications or is being applied gradually in current missions, or is in current development. It is intended that this book should document how NASA missions are becoming more autonomous and autonomic and should point to the way of making future missions highly - tonomous and autonomic. What is not covered is the supporting hardware of these missions or the intricate software that implements orbit and at- tude determination, on-board resource allocation, or planning and scheduling (though we refer to these technologies and give references for the interested reader).

This book de-emphasizes the formal mathematical description of spacecraft on-board attitude and orbit applications in favor of a more qualitative, concept-oriented presentation of these topics. The information presented in this book was originally given as a set of lectures in 1999 and 2000 instigated by a NASA Flight Software Branch Chief at Goddard Space Flight Center.  The Branch Chief later suggested this book.  It provides  an approachable insight into the area and is not intended as an essential reference work.ACS Without an Attitude is intended for programmers and testers new to the field who are seeking a commonsense understanding of the subject matter they are coding and testing in the hope that they will reduce their risk of introducing or missing the key software bug that causes an abrupt termination in their spacecraft’s mission.  In addition, the book will provide managers and others working with spacecraft with a basic understanding of this subject.

Explores some of the key issues related to agent technology from a formal perspective, following the overwhelming response to the timely FAABS workshops in this interdisciplinary field. All papers have been updated, expanded or represent new research and aim to provide a more in-depth treatment of the topic.The intended audience is:1. Researchers & practitioners of formal methods. For the researchers, this book gives an introduction to agent-based systems and an overview of research being undertaken in applying formal methods to agent-based systems.This book provides formal methods practitioners with an introduction to agent-based systems and gives them an in-depth look into some of the formal methods research being undertaken that is related to agent-based & distributed intelligent systems as well as formal methods tools and approaches being used in this area.2. Researchers & practitioners of agent-based systems. It provides an introduction to formal methods and examples of research that is being conducted in formal approaches to agent-based systems. It gives examples of how others have applied formal methods to agent-based systems as well as formal method tools and techniques that they can apply to their own systems. It also illustrates why it is non-trivial to perform verification and validation of these types of systems.

This book provides a novel perspective on the concept of memetics as applied to the development and evolution of intelligent robots and robotic communities/cultures. It provides a framework for the emergence of a hybrid community of people and intelligent robots collaborating to realize mutual benefits and scientific objectives. It aims to show that as the hybrid community emerges, so does its culture. Once this foundational work is done, the book illustrates the robot memetic ideas in the context of a space exploration scenario based on the development and operation of a human/robot settlement on Mars.

The idea of a FAABS workshop was first conceived in 1998 at the NASA Goddard Space Flight Center, while the Agent Technology Development Group in the Advanced Architectures and Automation Branch (Code 588) was developing a prototype agent community to automate satellite ground operations. While developing this system, several race conditions arose within and between agents. Due to the complexity of the agents and the communications between them, it was decided that a formal approach was needed to specify the agents and the communications between them, so that the system could be checked for additional errors. A formal model of the inter-agent communications was developed, with the expectation that this would enable us to find more errors. Success in this convinced us of the importance of using formal methods to model agent-based systems. To share our own experiences and to learn how others were approaching these issues, we decided to hold a workshop on formal methods and agent-based systems. The response was overwhelming. The result was the first FAABS workshop, which was held at the NASA Goddard Space Flight Center. Posters, paper presentations, panels, and an invited talk by J Moore stimulated much discussion and subsequent collaboration.
