UARS är en NASA ägs satellit som kommer att mata jordens atmosfär på kvällen fredagen den 23: e September. Satelliten kommer att bryta upp och faller över ett område på 300 kvadratkilometer, även om platsen för detta område är omöjligt att förutsäga. Chansen att någon som drabbats av något skräp är faktiskt ganska låg - 1 i 32000.
Satelliten inleddes 1991 och som NASA med data om atmosfäriska Fotokemi i 14 år.

Industry:Aerospace
(1) A non-photographic imaging system, which utilizes an oscillating mirror and fiber optic sensor array. The mirror sweeps from side to side, transmitting incoming energy to a detector array which sequentially outputs brightness values (that is, signal strengths) for successive pixels one swath at a time. The forward motion of the sensor platform carries the instrument to a position along its path where an adjacent swath can be imaged (2) For Landsats 1,2,3, 4, and 5 the Multispectral Scanner sensed radiation simultaneously by an array of six detectors in each of four spectral bands from 0.5 to 1.1 µm. See radiometer.

(1) A shade of grey representing a given radiometric level, or intensity, on the image. (2) A number or value assigned to a position (x, y) on the image proportional to the integrated output, reflectance, or transmittance of a small area, usually called a resolution cell or pixel, centered on the x, y position. Grey level can be measured or expressed as: transmittance, reflectance, brightness, radiance, luminance, density, voltage, current, or brightness value.
Industry:Aerospace
(1) A system that classifies, according to wavelength, all energy that moves, harmonically, at the constant velocity of light. (2) A continuum that is conventionally broken into arbitrary segments (as ultraviolet, visible, radio). The entire range of electromagnetic radiation. The spectrum usually is divided into seven sections. From the longest wavelengths to the shortest: radio, microwave, infrared, visible, ultraviolet, x-ray, and gamma ray radiation.

(1) An abbreviation of binary digit. (2) A unit of memory corresponding to the ability to store the result of a choice between two alternatives, used especially in connection with digital computing devices.
Industry:Aerospace
(1) Any method of computation consisting of a comparatively small number of steps, which are specifically adapted to the solution of a problem of some particular type. The steps are taken in a predetermined order, usually involving iteration. In computer terminology, an algorithm is a detailed logical procedure, or statement, which represents the solution of a particular problem. Most commonly, the term is used to indicate an analysis procedure such as that used for evaluation of a square root or for sorting a data file.
