Po wielu tygodniach ci\u0119\u017ckiej pracy uko\u0144czono niedawno najwi\u0119kszy aparat cyfrowy, jaki kiedykolwiek skonstruowano na potrzeby misji kosmicznej. Sk\u0142adaj\u0105ca si\u0119 ze 106 oddzielnych detektor\u00f3w elektronicznych \u201cmatryca o rozdzielczo\u015bci miliarda pikseli\u201d b\u0119dzie pe\u0142ni\u0142a rol\u0119 niezwykle czu\u0142ego \u201coka\u201d misji Gaia, realizowanej przez Europejsk\u0105 Agencj\u0119 Kosmiczn\u0105 (ESA) w celu sporz\u0105dzenia mapy galaktyk.<\/p>\n<\/div>\n

Podczas gdy go\u0142ym okiem w pogodn\u0105 noc mo\u017cna dostrzec kilka tysi\u0119cy gwiazd, sonda Gaia zbada miliard gwiazd w naszej galaktyce \u2013 Drodze Mlecznej. W trakcie pi\u0119cioletniej misji, kt\u00f3ra rozpocznie si\u0119 w 2013 roku, sonda przeka\u017ce najlepsze jak dot\u0105d dane dotycz\u0105ce po\u0142o\u017cenia i ruchu tych gwiazd, a tak\u017ce ich jasno\u015bci.<\/p>\n

Uk\u0142ad kamer Gaia<\/figcaption><\/figure>\n

Aby wykrywa\u0107 gwiazdy nawet milion razy s\u0142absze ni\u017c te widoczne go\u0142ym okiem, sonda Gaia b\u0119dzie wyposa\u017cona w uk\u0142ad matryc CCD (charge coupled devices), kt\u00f3re s\u0105 zaawansowanymi wersjami uk\u0142ad\u00f3w stosowanych w zwyk\u0142ych aparatach cyfrowych. Opracowane w Wielkiej Brytanii prostok\u0105tne detektory s\u0105 nieco mniejsze od karty kredytowej \u2013 ka\u017cdy z nich ma wymiary 4,7 x 6 cm \u2013 ale cie\u0144sze od ludzkiego w\u0142osa!<\/p>\n

Mozaika o wymiarach 0,5 x 1,0 metra zosta\u0142a zmontowana w zak\u0142adzie w Tuluzie nale\u017c\u0105cym do g\u0142\u00f3wnego wykonawcy misji Gaia, firmy Astrium France. Technicy starannie dopasowali do siebie poszczeg\u00f3lne matryce CCD, pozostawiaj\u0105c mi\u0119dzy nimi jedynie 1-milimetrow\u0105 szczelin\u0119. Pracuj\u0105c na dwie zmiany w \u015bci\u015ble kontrolowanych warunkach pomieszczenia czystego, montowali \u015brednio cztery matryce CCD dziennie, ostatecznie ko\u0144cz\u0105c zadanie 1 czerwca.<\/p>\n

Gotowa matryca przypomina niewielk\u0105 powierzchni\u0119 wy\u0142o\u017con\u0105 p\u0142ytkami, u\u0142o\u017con\u0105 w siedmiu rz\u0119dach. Na orbicie detektory b\u0119d\u0105 utrzymywane w temperaturze \u2013110\u00baC, co pozwoli zwi\u0119kszy\u0107 ich czu\u0142o\u015b\u0107. Sonda Gaia b\u0119dzie dzia\u0142a\u0107 w odleg\u0142o\u015bci 1,5 miliona km, po nocnej stronie Ziemi. W miar\u0119 obrotu sondy dwa teleskopy Gai b\u0119d\u0105 przemiata\u0107 niebo, szczeg\u00f3\u0142owo badaj\u0105c ka\u017cd\u0105 gwiazd\u0119, gdy ta pojawi si\u0119 w ich polu widzenia.<\/p>","protected":false},"excerpt":{"rendered":"
