Le miroir parabolique : la surface est un paraboloïde de révolution autour de l'axe principal. Si la source lumineuse est sensiblement un point au foyer du paraboloïde, le faisceau réfléchi est un faisceau cylindrique. Les réflecteurs de phares de marine ou d'automobiles sont souvent des miroirs paraboliques.

Preprocessing is an important and diverse set of image preparation programs that act to offset problems with the band data and recalculate DN [Digital Number] values that minimize these problems. Among the programs that optimize these values are atmospheric correction(affecting the DNs of surface materials because of radiance from the atmosphere itself, involving attenuation and scattering) ;Sun illumination geometry; surface-induced geometric distortions; spacecraft velocity and attitude variations(roll, pitch, and yaw) ;effects of Earth rotation, elevation, curvature(including skew effects), abnormalities of instrument performance(irregularities of detector response and scan mode such as variations in mirror oscillations) ;loss of specific scan lines(requires destriping), and others.

We report on the casting of the first 8. 4 meter diameter borosilicate honeycomb mirror at the Steward Observatory Mirror Laboratory. This blank will become the world's largest monolithic glass telescope mirror, and is the first of two mirrors for the Large Binocular Telescope Project. The honeycomb 8. 4 meter mirror was cast from 21 tons of E6 borosilicate glass manufactured by Ohara. This glass is melted into a mold constructed of aluminosilicate fiber to produce a honeycomb structure with roughly 20% of solid density. The 1662 hexagonal voids that form the honeycomb structure are produced by ceramic fiber boxes bolted to the bottom of the mold with SiC bolts. The furnace rotates at 6. 8 rpm during the casting process to produce the F/1. 14 paraboloid on the front surface. This shaping minimizes the amount of glass which must be removed during the grinding process. The front faceplate of the mirror will be 28 mm thick after generating and the back faceplate will be 25 mm. The overall thickness of the finished honeycomb blank is 89 cm at the outer edge and 44 cm at the central hole. 3, record 13, English, - honeycomb%20mirror

Cette méthode de fabrication a été mise au point sur des miroirs de plus en plus grands, en commençant par un miroir de 3,50m pour le télescope WYNN à Kitt Peak (Arizona). Les premiers «grands» miroirs ont été coulés pour le MMT (ex Multi Mirror Telescope), puis pour les deux télescopes Magellan de 6.50m, et en ce moment, pour le premier des deux miroirs de 8,4m du LBT (Large Binocular Telescope). 2, record 13, French, - miroir%20alv%C3%A9ol%C3%A9

The Orlan spacesuit was used for Russian EVA's on Salyut, Mir, and the International Space Station. It was designed by the Zvezda OKB [Russia : Experimental Design Bureau], and derived from the Kretchet suit intended for use on the lunar surface. It consisted of flexible limbs attached to a one-piece rigid body/helmet unit. The suit was entered through a hatch in the rear of the torso. The exterior of the hatch housed the life support equipment. Maximum operation time was three hours when the Orlan-D version of the suit was first used on Salyut 6. Later Orlan-DM versions of the suit increased this period to nine hours. The integrated design meant that no external hoses were required as in the American space suits. The suit standard pressure was 0. 40 atmospheres, so that a prebreathe period of only 30 minutes was required. Electrical power and communications were via an umbilical cord to the station. Control of the suit was via a panel on the chest, with the markings in mirror image. The cosmonaut viewed the panel using a mirror on the wrist of the suit. 8, record 14, English, - Orlan%20spacesuit

It was decided to grind the edges of the mirror to make it truly circular, as the rough cast glass was some 3/8 inch longer on one diameter than on the other. This operation called for setting up an auxiliary cast iron grinding wheel to operate against the periphery of the turntable of the main machine. Two or three nights work with this apparatus gave us a truly circular edge with a rough ground surface. Next, several nights were devoted to smoothing up both faces of the mirror, and bringing these two planes to approximate parallelism.... 2, record 15, English, - rough%20cast%20glass

Sun glint occurs when the ocean acts like a mirror, directly reflecting the sunlight to the imager of the satellite. Therefore, sun glint, like an image in a mirror, provides two kinds of information. It can help to locate the position of the sun, and its varying brightness and clarity provide information about the reflecting surface. In this way, sun glint is used to study ocean surface activity. 2, record 17, English, - sun%20glint

When these particles drift around the Earth, they do not remain on common field lines unless the geomagnetic field distribution is axially symmetric. This effect has been called "drift shell splitting"... A drift shell is uniquely determined by the coordinate pair(Bm, Lm) as a surface formed by segments of magnetic field lines between conjugate mirror points. Therefore, drift shells which are tangent to one another or cut one another at a given longitude or local time where they have a common segment of field line, generally are separate from one another at a different longitude or local time---in Roederer's terms these drift shells "split". But since these drift shells are different entities from the outset, there is no real need to infer a notion of splitting. 2, record 18, English, - shell%20splitting
