Book Description
Mars Outpost provides a detailed insight into the various technologies, mission architectures, medical requirements, and training needed to send humans to Mars. It focuses on mission objectives and benefits, and the risks and complexities that are compounded when linked to an overall planet exploration program involving several expeditions and setting up a permanent presence on the surface. The first section provides the background to sending a human mission to Mars. Analogies are made with early polar exploration and the expeditions of Shackleton, Amundsen, and Mawson. The interplanetary plans of the European Space Agency, NASA, and Russia are examined, including the possibility of one or more nations joining forces to send humans to Mars. Current mission architectures, such as NASA’s Constellation, ESA’s Aurora, and Ross Tierney’s DIRECT, are described and evaluated. The next section looks at how humans will get to the Red Planet, beginning with the preparation of the crew. The author examines the various analogues to understand the problems Mars-bound astronauts will face. Additional chapters describe the transportation hardware necessary to launch 4-6 astronauts on an interplanetary trajectory to Mars, including the cutting edge engineering and design of life support systems required to protect crews for more than a year from the lethal radiation encountered in deep space. NASA’s current plan is to use standard chemical propulsion technology, but eventually Mars crews will take advantage of advanced propulsion concepts, such as the Variable Specific Impulse Magnetoplasma Rocket, ion drives and nuclear propulsion. The interplanetary options for reaching Mars, as well as the major propulsive maneuvers required and the trajectories and energy requirements for manned and unmanned payloads, are reviewed . Another chapter addresses the daunting medical problems and available countermeasures for humans embarking on a mission to Mars: the insidious effects of radiation on the human body and the deleterious consequences of bone and muscle deconditioning. Crew selection will be considered, bearing in mind the strong possibility that they may not be able to return to Earth. Still another chapter describes the guidance, navigation, and control system architecture, as well as the lander design requirements and crew tasks and responsibilities required to touch down on the Red Planet. Section 3 looks at the surface mission architectures. Seedhouse describes such problems as radiation, extreme temperatures, and construction challenges that will be encountered by colonists. He examines proposed concepts for transporting cargo and astronauts long distances across the Martian surface using magnetic levitation systems, permanent rail systems, and flying vehicles. In the penultimate chapter of the book, the author explains an adaptable and mobile exploration architecture that will enable long-term human exploration of Mars, perhaps making it the next space-based tourist location.

Book Description
Lunar Outpost provides a detailed account of the various technologies, mission architectures, medical requirements and training needed to return humans to the Moon within the next decade. It focuses on the means by which a lunar outpost will be constructed and also addresses major topics such as the cost of the enterprise and the roles played by private companies and individual countries. The return of humans to the surface of the Moon will be critical to the exploration of the solar system. The various missions are not only in pursuit of scientific knowledge, but also looking to extend human civilization, economic expansion, and public engagement beyond Earth. As well as NASA, China’s Project 921, Japan’s Aerospace Exploration Agency, Russia, and the European Space Agency are all planning manned missions to the Moon and, eventually, to Mars. The Ares-I and Ares-V are the biggest rockets since the Saturn V and there is much state-of-the-art technology incorporated into the design of Orion, the spacecraft that will carry a crew of four astronauts to the Moon. Lunar Outpost also describes the human factors, communications, exploration activities, and life support constraints of the missions.

Book Description
The Intelligent Transportation System (ITS) Program is a cooperative effort by government, private industry, and academia to apply advanced technology to the task of resolving the problems of surface transportation. The objective is to improve travel efficiency and mobility, enhance safety, conserve energy, provide economic benefits, and protect the environment. The current demand for mobility has exceeded the available capacity of the roadway system. Because the highway system cannot be expanded, except in minor ways, the available capacity must be used more efficiently to handle the increased demand. ITS applies advanced information processing, communication, sensing, and computer control technologies to the problems of surface transportation. Considerable research and development efforts will be required to produce these new technologies and to convert technologies developed in the defense and space programs to solve surface transportation problems. ITS has been subdivided into six interlocking technology areas. This book addresses human factors concerns for four of these areas: * Advanced Traveler Information Systems are a variety of systems that provide real time, in-vehicle information to drivers regarding navigation and route guidance, motorist services, roadway signing, and hazard warnings. * Advanced Vehicle Control Systems refer to systems that aid drivers in controlling their vehicle particularly in emergency situations and ultimately taking over some or all of the driving tasks. * Commercial Vehicle Operations address the application of ITS technologies to the special needs of commercial roadway vehicles including automated vehicle identification, location, weigh-in-motion, clearance sensing, and record keeping. * Advanced Traffic Management Systems monitor, control and manage traffic on streets and highways to reduce congestion using vehicle route diversion, automated signal timing, changeable message signs, and priority control systems. Two technical areas are not specifically addressed in individual chapters, but many aspects of them are covered in associated chapters: * Advanced Rural Transportation Systems include systems that apply ITS technologies to the special needs of rural systems and include emergency notification and response, vehicle location, and traveler information. * Advanced Public Transportation Systems enhance the effectiveness, attractiveness and economics of public transportation and include fleet management, automated fare collection, and real-time information systems.

Book Description
Sections 10 to 13 of the Advanced Transportation System Studies final report are included in this volume. Section 10 contains a copy of an executive summary that was prepared by Lockheed Space Operations Company (LSOC) to document their support to the TA-2 contract during the first-year period of performance of the contract, May 1992 through May 1993. LSOC participated on the TA-2 contract as part of the concurrent engineering launch system definition team, and provided outstanding heavy lift launch vehicle (HLLV) ground operations requirements and concept assessments for Lockheed Missiles and Space Company (LMSC) through an intercompany work transfer as well as providing specific HLLV ground operations assessments at the direction of NASA KSC through KSC funding that was routed to the TA-2 contract. Section 11 contains a copy of a vehicle-independent, launch system health management requirements assessment. The purpose of the assessment was to define both health management requirements and the associated interfaces between a generic advanced transportation system launch vehicle and all related elements of the entire transportation system, including the ground segment. Section 12 presents the major TA-2 presentations provided to summarize the significant results and conclusions that were developed over the course of the contract. Finally, Section 13 presents the design and assessment report on the first lunar outpost heavy lift launch vehicle.
