A variety of antisatellite weapons could destroy, blind or jam enemy satellites.... Lasers might work best, because by blinding rather than destroying satellites, they would not fill lower Earth orbits with debris that other spacecraft might run into.  5, fiche 1, Anglais, - laser%20weapon

Essential elements of a laser weapon are the high-energy laser-producing system and the beam control system which aims the laser beam at the target and focuses the laser on it.  6, fiche 1, Anglais, - laser%20weapon

En raison de leur orbite prévisible, les satellites seraient particulièrement exposés aux attaques par laser qui permettraient d'aveugler les capteurs, de saturer l'équipement électronique, d'entraîner des dégâts thermiques ou physiques, ou de surchauffer des composants particuliers (par exemple, la partie optique sensible de la charge utile ou les détecteurs d'attitude).  3, fiche 1, Français, - arme%20laser

On an image, changes in shape and position of objects with respect to their true shape and position, causes are not related to the sensor.  4, fiche 2, Anglais, - image%20distortion

Record number: 2, Textual support number: 1 CONT

An image distortion [is] caused by the fact that a tall object might be perceived by the orbiting spacecraft as being closer than an adjacent lower object. In image processing, the tall object might be mistakenly placed at a ground location which is closer than the low object, though in truth the ordering is opposite.  1, fiche 2, Anglais, - image%20distortion

Previous studies of the Sun have only been done in the Ecliptic, and are thus a small glimpse of the dynamic solar environment. Although it will get no closer to the Sun than it was the day it was launched, the Ulysses spacecraft will provide a unique opportunity to explore the Heliosphere in total. It carries a 55 kg(121 lbm) instrument payload to collect data on the solar magnetic field, solar radiation such as radio and plasma waves and X-rays, and the solar wind, as well as cosmic radiation and dust entering the solar system. There are nine instruments :... Unified Radio and Plasma Wave Experiment(URAP) to measure high frequency radio waves and lower frequency plasma waves...  2, fiche 3, Anglais, - unified%20radio%20and%20plasma%20wave%20experiment

regulated bus : For geosynchronous spacecraft, power control is usually one of two systems : sun-regulated bus, or fully regulated bus. While sun-regulated systems have a lower mass, a recent study... shows many advantages to the fully regulated bus. In addition to peak power delivered by this system's regulators, it is also considered more reliable in terms of power lock-up due to the fact that it uses constant voltage.  2, fiche 4, Anglais, - regulated%20bus%20system

The Measurement of Pollution in the Troposphere(MOPITT) is an eight-channel gas correlation radiometer to be launched on EOS/AM1 spacecraft in 1998. The goal of the experiment is to support studies of the oxidizing capacity of the lower atmosphere on large scales by measuring the global distributions of carbon monoxide(CO) and methane(CH 4) and thus, will represent a significant advancement in the application of space based remote sensing to global tropospheric chemistry research.  2, fiche 5, Anglais, - measurement%20of%20pollution%20in%20the%20troposphere
