The Science Instruments On The WIND Spacecraft
The aim of ISTP is to understand the behavior of the solar-terrestrial plasma environment in order to predict how the Earth's atmosphere will respond to changes in solar wind conditions. WIND's objective is to measure the properties of the solar wind before it reaches the Earth. The WIND spacecraft has an array of instruments including: Konus, the Wind Magnetic Field Investigation (MFI), the Solar Wind and Suprathermal Ion Composition Experiment (SMS), The Energetic Particles: Acceleration, Composition, and Transport (EPACT) investigation, the Solar Wind Experiment (SWE), a Three-Dimensional Plasma and Energetic Particle Investigation (3DP), the Transient Gamma-Ray Spectrometer (TGRS), and the Radio and Plasma Wave Investigation (WAVES) . The Konus and TGRS instruments are primarily for gamma-ray and high energy photon observations of solar flares or gamma-ray bursts. The SMS experiment measures the mass and mass-to-charge ratios of heavy ions. The SWE and 3DP experiments are meant to measure/analyze the lower energy (below 10 MeV) solar wind protons and electrons. The WAVES and MFI experiments were designed to measure the electric and magnetic fields observed in the solar wind. All together, the WIND spacecraft's suite of instruments allows for a complete description of plasma phenomena in the solar wind plane of the ecliptic.

Famous quotes containing the words science, instruments and/or wind:
“What happened at Hiroshima was not only that a scientific breakthrough ... had occurred and that a great part of the population of a city had been burned to death, but that the problem of the relation of the triumphs of modern science to the human purposes of man had been explicitly defined.”
—Archibald MacLeish (1892–1982)
“Whilst Marx turned the Hegelian dialectic outwards, making it an instrument with which he could interpret the facts of history and so arrive at an objective science which insists on the translation of theory into action, Kierkegaard, on the other hand, turned the same instruments inwards, for the examination of his own soul or psychology, arriving at a subjective philosophy which involved him in the deepest pessimism and despair of action.”
—Sir Herbert Read (1893–1968)
“When we think of him, he is without a hat, standing in the wind and weather. He was impatient of topcoats and hats, preferring to be exposed, and he was young enough and tough enough to enjoy the cold and the wind of those times.... It can be said of him, as of few men in a like position, that he did not fear the weather, and did not trim his sails, but instead challenged the wind itself, to improve its direction and to cause it to blow more softly and more kindly over the world and its people.”
—E.B. (Elwyn Brooks)
