NASA Earth Science Enterprise Missions The purpose of NASA's Earth-Sun System Science is to develop a scientific understanding of the Earth System and it's response to natural or human-induced changes to enable improved prediction capability for climate, weather, and natural hazards. The program has an end-to-end strategy to assure that all the information, understanding, and capabilities derived from it's research program achieve maximum usefulness to the scientific and decision-making communities. Increasing our knowledge of the Earth system is the goal of NASA's research on the Earth-Sun System, which is complemented by an applications and a technology program. |

The goal of the Human Exploration and Development of Space (HEDS) Enterprise is to open the space frontier by exploring, using and enabling the development of space. Our programs provide safe, assured transportation to and from space for people and payloads, and develop and operate habitable space facilities in order to enhance scientific knowledge, support technology development, and enable commercial activity. |

It's hard to communicate the full sense of wonder that floods through us at such a moment, but we all understand. At least once, the dimly glittering night sky has stopped us in our tracks, bringing quiet contemplation of how the Universe came to be and what our relationship is to everything within it. NASA's Origins Program seeks to answer two enduring human questions that we once considered around ancient campfires, yet still keep alive in today's classrooms: Where do we come from? Are we alone?

NASA's Cosmic Journeys: The Structure and Evolution of the Universe Theme Cosmic Journeys is a new series of space-science missions that will explore the essence of time, gravity, matter, and energy. What powered the Big Bang? What is the Universe made of? What is the nature of space and time? These are the key questions that Cosmic Journeys seeks to answer. Cosmic Journeys brings together the traditionally independent camps of astronomers and particle physicists to search for unknown forces and new physics. The goal is to move beyond physics' "standard model" and establish a new set of natural laws that unites the currently immiscible pillars of quantum physics and general relativity. |

The Sun Earth Connection is another one of the four space science themes for the Office of Space Science at NASA. By exploring the site you will be able to understand the changing Sun and its effects on the Solar System, life, and society. Goddard Space Flight Center is the lead NASA Center for the SEC Theme. |

ESA, the European Space Agency, provides a vision of Europe’s future in space, and of the benefits for people on the ground that satellites can supply. It also develops the strategies needed to fulfil the vision, through collaborative projects in space science and technology. So ESA is not just a technical organization but part of Europe’s economic and social fabric, and of its culture of knowledge and skill. To sustain this success in the 21st Century, the Member States continue to look to ESA for opportune and carefully conceived multinational space projects and for help in improving their industrial competitiveness. ESA also coordinates the broad thinking needed to meet new challenges.

The NOZOMI (PLANET-B) is the first Japanese Mars orbiter. It was launched on July 4, 1998, on the second flight of the M-V launch vehicle from Kagoshima Space Center. The primary scientific objective of the PLANET-B program is to study the Martian upper atmosphere with emphasis on its interaction with the solar wind. NOZOMI weighs 541 kg, including the fuel for attitude and orbit control, and will have an orbit around Mars with 150 km periapsis and 15 Mars radii apoapsis on its arrival at Mars. The NOZOMI is now in its heliocentric orbit to arrive at Mars early in 2004.
