Telescopul spa\u021bial Hubble (HST) este cel mai faimos \u2013 \u0219i probabil cel mai de succes \u2013 observator spa\u021bial lansat vreodat\u0103. Telescopul de 11 tone a fost plasat pe o orbit\u0103 \u00een jurul P\u0103m\u00e2ntului, la o altitudine de 570 km, de c\u0103tre naveta spa\u021bial\u0103, \u00een aprilie 1990. \u00cenconjur\u00e2nd planeta noastr\u0103 la fiecare 96 de minute, HST a parcurs p\u00e2n\u0103 \u00een prezent aproximativ 5 miliarde de km.<\/p>\n<\/div>\n

Hubble a transmis o cantitate imens\u0103 de date \u0219tiin\u021bifice \u0219i imagini incredibil de detaliate ale tuturor tipurilor de obiecte din cer. P\u00e2n\u0103 \u00een toamna anului 2009, acesta efectuase aproape 900.000 de observa\u021bii \u0219i capturase peste 570.000 de imagini ale a mai mult de 29.000 de obiecte.<\/p>\n

HST poart\u0103 numele lui Edwin Hubble (1889\u20131953), unul dintre marii pionieri ai astronomiei moderne. Elementele sale centrale sunt o oglind\u0103 principal\u0103 de 2,4 m \u0219i cinci instrumente \u0219tiin\u021bifice care studiaz\u0103 Universul \u00een infraro\u0219u, \u00een lumina vizibil\u0103 sau \u00een ultraviolet. Lumina captat\u0103 de oglinda principal\u0103 este reflectat\u0103 c\u0103tre o oglind\u0103 mai mic\u0103 \u0219i apoi transmis\u0103 c\u0103tre instrumente. Datele sunt apoi transmise c\u0103tre P\u0103m\u00e2nt prin intermediul unui satelit de releu.<\/p>\n

Alimentarea cu energie electric\u0103 a observatorului este asigurat\u0103 de dou\u0103 panouri solare de mari dimensiuni (2,6 x 7,1 m). Senzorii de ghidare de precizie sunt folosi\u021bi pentru a se alinia pe stelele-ghid. Acest lucru asigur\u0103 precizia extrem de ridicat\u0103 a orient\u0103rii, necesar\u0103 pentru efectuarea unor observa\u021bii foarte precise.<\/p>\n

Hubble este singurul telescop conceput vreodat\u0103 pentru a fi \u00eentre\u021binut \u00een spa\u021biu de c\u0103tre astronau\u021bi, astfel \u00eenc\u00e2t instrumentele vechi s\u0103 poat\u0103 fi \u00eenlocuite. Acest lucru s-a dovedit a fi de nepre\u021buit atunci c\u00e2nd primele imagini au ap\u0103rut neclare \u0219i a fost necesar\u0103 instalarea unui sistem optic special pentru a remedia problema, \u00een 1993. Au avut loc cinci misiuni de \u00eentre\u021binere, ultima dintre ele desf\u0103\u0219ur\u00e2ndu-se \u00een mai 2009. Se preconizeaz\u0103 c\u0103 telescopul va continua s\u0103 func\u021bioneze p\u00e2n\u0103 \u00een 2014.<\/p>","protected":false},"excerpt":{"rendered":"
