P\u00e4rast mitme n\u00e4dala pikkust rasket t\u00f6\u00f6d valmis hiljuti k\u00f5igi aegade suurim kosmosemissiooniks ehitatud digikaamera. 106 eraldi elektroonilisest detektorist koosnev \u201cmiljardi pikseli maatriks\u201d hakkab toimima ESA galaktika kaardistamise missiooni Gaia \u00fclitundliku \u201csilmana\u201d.<\/p>\n<\/div>\n

Kui selgel \u00f6\u00f6l on palja silmaga n\u00e4ha mitu tuhat t\u00e4hte, siis Gaia uurib miljardit t\u00e4hte meie enda Linnutee galaktikas. 2013. aastal algava viieaastase missiooni jooksul saadab Gaia tagasi seni parimad andmed nende t\u00e4htede asukoha, liikumise ja heleduse kohta.<\/p>\n

Selleks, et avastada t\u00e4hti, mis on kuni miljon korda n\u00f5rgemad kui inimese silm suudab n\u00e4ha, on Gaia varustatud laetud seosega andurite (CCD) massiiviga, mis on igap\u00e4evastes digikaamerates kasutatavate kiipide t\u00e4iustatud versioonid. \u00dchendkuningriigis v\u00e4lja t\u00f6\u00f6tatud need ristk\u00fclikukujulised detektorid on veidi v\u00e4iksemad kui krediitkaart \u2013 iga\u00fche m\u00f5\u00f5tmed on 4,7 x 6 cm \u2013, kuid \u00f5hemad kui inimjuuks!<\/p>\n

0,5 x 1,0 meetri suurune mosaiik pandi kokku Gaia peamise t\u00f6\u00f6v\u00f5tja Astrium France\u2019i Toulouse\u2019i tehases. Tehnikud paigutasid iga CCD-anduri hoolikalt kokku, j\u00e4ttes nende vahele vaid 1 mm suuruse vahe. T\u00f6\u00f6tades kahes vahetuses rangetes puhasruumi tingimustes, lisasid nad p\u00e4evas keskmiselt neli CCD-andurit ning viisid oma \u00fclesande l\u00f5pule 1. juunil.<\/p>\n

Valmis andurite massiiv meenutab v\u00e4ikest plaaditud pinda, mis on paigutatud seitsmesse rida. Orbiidil hoitakse detektoreid temperatuuril \u2013110 \u00b0C, et suurendada nende tundlikkust. Gaia t\u00f6\u00f6tab 1,5 miljoni km kaugusel, Maa \u00f6\u00f6poolel. P\u00f6\u00f6rlemise k\u00e4igus liiguvad Gaia kaks teleskoopi \u00fcle taevalaotuse, uurides iga t\u00e4hte \u00fcksikasjalikult, kui see liigub nende vaatev\u00e4lja l\u00e4bi.<\/p>","protected":false},"excerpt":{"rendered":"
