Hubble\u2019i kosmoseteleskoop (HST) on k\u00f5ige kuulsam \u2013 ja t\u00f5en\u00e4oliselt ka k\u00f5ige edukam \u2013 kosmosobservatoorium, mis kunagi orbiidile on viidud. 11-tonnine teleskoop viidi 1990. aasta aprillis kosmoses\u00fcstiku abil 570 km k\u00f5rgusele Maa \u00fcmber tiirlevale orbiidile. HST tiirleb \u00fcmber meie planeedi iga 96 minuti j\u00e4rel ja on seni l\u00e4binud umbes 5 miljardit kilomeetrit.<\/p>\n<\/div>\n

Hubble on saatnud tagasi tohutu hulga teadusandmeid ja uskumatult \u00fcksikasjalikke pilte igat liiki taevakehadest. 2009. aasta s\u00fcgiseks oli ta teinud ligi 900 000 vaatlust ja pildistanud \u00fcle 570 000 pildi enam kui 29 000 objektist.<\/p>\n

HST on nimetatud Edwin Hubble\u2019i (1889\u20131953) auks, kes oli \u00fcks kaasaegse astronoomia suurimaid teerajajaid. Selle s\u00fcdameks on 2,4-meetrine peapeegel ja viis teadusinstrumenti, millega uuritakse universumit infrapuna-, n\u00e4htava v\u00f5i ultraviolettkiirguse abil. Peapeegli poolt kogutud valgus peegeldub v\u00e4iksemale peeglile ja suunatakse seej\u00e4rel instrumentidele. Andmed edastatakse seej\u00e4rel Maale vahesatelliidi kaudu.<\/p>\n

Observatooriumi elektrienergiaga varustavad kaks suurt (2,6 \u00d7 7,1 m) p\u00e4ikesepaneeli. Juhit\u00e4htedele suunamiseks kasutatakse t\u00e4ppisjuhtimissensoreid. See tagab \u00e4\u00e4rmiselt k\u00f5rge suunamis t\u00e4psuse, mis on vajalik v\u00e4ga t\u00e4psete vaatluste tegemiseks.<\/p>\n

Hubble on ainus teleskoop, mis on kunagi projekteeritud nii, et astronaudid saaksid seda kosmoses hooldada, et vanu instrumente saaks asendada. See osutus hindamatuks, kui esimesed pildid olid udused ja 1993. aastal tuli probleemi lahendamiseks paigaldada spetsiaalne optiline s\u00fcsteem. Hooldusmissioone on olnud viis, viimane neist toimus 2009. aasta mais. Eeldatakse, et teleskoop j\u00e4\u00e4b t\u00f6\u00f6sse kuni 2014. aastani.<\/p>","protected":false},"excerpt":{"rendered":"
