  • From John Glenn s mission to orbit Earth to the International Space Station program, space food research has met the challenge of providing food that tastes good and travels well in space. To better understand this process, we can look back through history. Explorers have always had to face the problem of how to carry enough food for their journeys. Whether those explorers are onboard a sailing ship or on the Space Shuttle, adequate storage space has been a problem.

  • Photograph* of Faith from space show no political boundaries, reminding us that national distinctions arc man made. But the agencies responsible for those pictures, other missions to Earth orbit, and probes to deep space are inevitably national or multinational. Each has its own set of constituencies, procedures, capabilities, and limitations.

  • The steps needed to define a successful space science mission are numerous. The science drivers, the unique advantages this mission provides over past missions or earth-based experiments, and the payload that it includes are the key factors to guarantee its success. Finding the required information on such topics is not so straightforward, especially as they are usually outside the scope of undergraduate courses. The 2003 Canary Islands Winter School of Astrophysics aimed at providing a focused framework that helps fill this need.

  • This report was originally released in December 2004 in prepublication form as the first report of a two-phase study to be carried out by the same committee. The first phase was sponsored by the National Aeronautics and Space Administration (NASA) and focused on the Tropical Rainfall Measuring Mission (TRMM). The second phase was sponsored by the National Oceanic and Atmospheric Administration and focused on the Global Precipitation Measurement mission. The report of the second phase will be published in a separate volume in 2006.

  • Mutual funds are one of the several options that investors explore for investing surplus funds. In a deposit-dominated market like India it is important for mutual funds to be able to offer differentiated risk-rewards and gain shelf-space. With many seemingly similar offerings from multiple mutual funds unable to clearly communicate their superiority, a less informed investor may find it difficult to make a choice. This uncertainty leads to a weakened ‘pull’ for the product.

  • The successful accomplishment of a space mission is dependent on proper and reliable functioning of the power system of the spacecraft in orbit. The stringent demands on performance including weight, volume, reliability, durability, and cost make the design of the spacecraft power system a challenging exercise. Further, since a space mission is inherently expensive, the necessity of optimization and built-in reliability becomes a rule rather than an exception for all the onboard systems.

  • The total rebuilding of Pier A in 1995 and the construction of a link to Terminal 1 in 1998 was designed by the architect firm Holm & Grut A/S. The most characteristic feature of the pier is its modern version of fan vaulting supporting the aluminium wing structures that make up the roof. These curved roofs and the glass facades form reflecting surfaces that create the space and light that is the hallmark of Nordic architecture. Holm & Grut wanted to create a building that would give arriving passengers an immediate experience of Scandinavian design.

  • This book deals with topics in atomic and molecular structure and dynamics that are important to astronomy. Indeed, the topics selected are of central interest to the field of astronomy, many having been initiated by the needs of understanding worlds other than ours. Except for some lunar surface material returned by the Apollo missions, and material naturally delivered to us by cosmic rays, comets, and meteors, our only access to the other worlds of our astronomical Universe is through our observations of electromagnetic radiation from them.

  • In January 2004, President George W. Bush announced new elements of the national space policy by issuing the Vision for Space Exploration (VSE). The new policy set out goals for NASA, including that of exploring the “solar system and beyond” with human and robotic missions—specifically, to “extend human presence across the solar system, starting with a human return to the Moon by the year 2020.” In the year that followed, NASA created the Exploration Systems Mission Directorate (ESMD) as the primary agent for the development of the exploration program.

  • Generating electricity from a heat source using no moving mechanical parts is the ultimate goal of the Defense Threat Reduction Agency’s thermionics program. However, developing thermionic energy conversion devices has proven difficult, although much progress has been made. In spite of initial success during the late 1960s and intermittent funding since that time, for a variety of reasons no thermionic system has yet been developed in the United States that can be used today on Earth or in space.
