This report is intended to record and communicate to our colleagues, stakeholders, and the public at large about heliophysics scientific and flight program achievements and milestones for 2008, for which NASA Goddard Space Flight Center's Heliophysics Science Division (HSD) made important contributions. HSD comprises approximately 261 scientists, technologists, and administrative personnel dedicated to the goal of advancing our knowledge and understanding of the Sun and the wide variety of domains that its variability influences. HSD's Mission is to explore the Sun's interior and atmosphere,...

With the launch of the Constellation program, NASA finds itself with the opportunity to design the next generation of manned vehicles that will take man to the Moon and beyond in the next two decades. While there are precedents for many aspects of the design, development, test, and evaluation (DDT&E) task at hand - the Apollo program, Space Transportation System, International Space Station (ISS) and others - the Johnson Space Center (JSC) Astronaut Office asked for a fresh look at first principles during the formative times of this new program. As a result, a team directed by the NASA...

NASA is currently in the process of developing the next generation crewed and cargo launch vehicles and spacecraft to return to the Moon and beyond. With the experience and knowledge base available to NASA from past similar programs, it is important to develop a document that captures the salient aspects of successful programs and serve as an important guide in evaluating next generation and future spacecraft concepts and proposals. This section outlines design, development, testing, and evaluation best practices for robust, reliable space systems. The scope of the section is limited to the...

During 2010, there are two major eclipses of the Sun. The first is an annular eclipse on January 15 and the second is a total eclipse on July 11. This section is a general description of the tables, maps, and figures appearing in the later sections for each eclipse. On Friday, 2010 January 15, an annular eclipse of the Sun is visible from within a 300 km wide track that traverses half of Earth. The path of the Moon's antumbral shadow begins in Africa and passes through Chad, Central African Republic, Democratic Republic of the Congo, Uganda, Kenya, and So-malia. After leaving Africa, the path...

The Earth, including its gaseous envelope, is a very small interactive part of the solar system. As such, it is also a part of the interactive dynamic structure of the galaxy and the universe. Existing within this dynamic material and energetic macrocosm, the Earth is subject to varying forces and energy fields. Though the Earth, in turn, affects the macrocosm, its effect is small indeed. Answers to questions concerning climate and its changes are difficult to formulate. Why? Because many authors have tried to define the "climate" and have a different understanding of what climate is. Until...

The activities presented are a broad based approach to advancing key hydrogen related technologies in areas such as fuel cells, hydrogen production, and distributed sensors for hydrogen-leak detection, laser instrumentation for hydrogen-leak detection, and cryogenic transport and storage. Presented are the results from research projects, education and outreach activities, system and trade studies. The work will aid in advancing the state-of-the-art for several critical technologies related to the implementation of a hydrogen infrastructure. Activities conducted are relevant to a number of...

This report documents the activities, findings, and NASA Engineering and Safety Center (NESC) recommendations of a multidiscipline team to independently assess the Constellation Program (CxP) Crew Exploration Vehicle (CEV) Parachute Assembly System (CPAS). This assessment occurred during a period of 15 noncontiguous months between December 2008 and April 2010, prior to the CPAS Project's Preliminary Design Review (PDR) in August 2010. The assessment team's planned objectives were to identify reliability-enhancing opportunities for the CPAS Project: Parachute system design, Reliability...
