Wi\u0119kszo\u015b\u0107 statk\u00f3w kosmicznych umieszcza si\u0119 na orbitach wok\u00f3\u0142 Ziemi. Nie zawsze jednak jest to optymalne miejsce dla satelit\u00f3w naukowych badaj\u0105cych odleg\u0142y wszech\u015bwiat.<\/p>\n<\/div>\n

Kosmiczny teleskop Hubble'a porusza si\u0119 po orbicie ko\u0142owej na wysoko\u015bci 600 km nad powierzchni\u0105 Ziemi, nachylonej pod k\u0105tem 28,5 stopnia wzgl\u0119dem r\u00f3wnika. Taka orbita wok\u00f3\u0142 Ziemi u\u0142atwia napraw\u0119 i konserwacj\u0119 obserwatorium. Jednak Ziemia i Ksi\u0119\u017cyc zas\u0142aniaj\u0105 znaczne fragmenty nieba.<\/p>\n

Nast\u0119pca teleskopu Hubble\u2019a, Kosmiczny Teleskop im. Jamesa Webba, b\u0119dzie dzia\u0142a\u0142 znacznie dalej. Zostanie umieszczony na stabilnej orbicie w tzw. punkcie Lagrange\u2019a L2, oddalonym o 1,5 miliona km po stronie nocnej Ziemi.<\/p>\n

L2 to jeden z pi\u0119ciu punkt\u00f3w Lagrange\u2019a Ziemi. W tych punktach si\u0142y grawitacyjne Ziemi, Ksi\u0119\u017cyca i S\u0142o\u0144ca znosz\u0105 si\u0119 nawzajem, dzi\u0119ki czemu \u0142atwo jest utrzyma\u0107 satelit\u0119 w tej samej pozycji.<\/p>\n

Inne satelity, takie jak obserwatorium SOHO nale\u017c\u0105ce do ESA, musz\u0105 nieustannie obserwowa\u0107 S\u0142o\u0144ce. Sonda ta znajduje si\u0119 w punkcie Lagrange\u2019a L1, 1,5 miliona km od Ziemi w kierunku S\u0142o\u0144ca.<\/p>\n

Poniewa\u017c si\u0142y grawitacyjne Ziemi i S\u0142o\u0144ca r\u00f3wnowa\u017c\u0105 si\u0119 w punkcie L1, sonda SOHO mo\u017ce nieustannie kr\u0105\u017cy\u0107 mi\u0119dzy nimi, nie zu\u017cywaj\u0105c przy tym zbyt wiele paliwa.<\/p>","protected":false},"excerpt":{"rendered":"
