Nasze codzienne \u017cycie obejmuje takie czynno\u015bci, jak siedzenie, chodzenie, podnoszenie przedmiot\u00f3w z pod\u0142ogi i le\u017cenie w \u0142\u00f3\u017cku. \u017badna z tych czynno\u015bci nie jest mo\u017cliwa na orbicie.<\/p>\n<\/div>\n

Gdy statek kosmiczny osi\u0105gnie orbit\u0119, wszystko w jego wn\u0119trzu wydaje si\u0119 by\u0107 w stanie niewa\u017cko\u015bci. Ka\u017cda rzecz (lub osoba), kt\u00f3ra nie jest przymocowana, b\u0119dzie unosi\u0107 si\u0119 w powietrzu.<\/p>\n

Astronauci po raz pierwszy odczuwaj\u0105 skutki niewa\u017cko\u015bci w momencie wy\u0142\u0105czenia silnik\u00f3w rakietowych. Natychmiast zaczynaj\u0105 unosi\u0107 si\u0119 w powietrzu, przytrzymywani jedynie przez pasy bezpiecze\u0144stwa. Niewa\u017cko\u015b\u0107 sprawia, \u017ce astronauci wydaj\u0105 si\u0119 niezwykle silni. Potrafi\u0105 podnosi\u0107 przedmioty, kt\u00f3re na Ziemi by\u0142yby o wiele zbyt ci\u0119\u017ckie, by je przenie\u015b\u0107. Istniej\u0105 jednak pewne wady.<\/p>\n

Bez dzia\u0142ania grawitacji krew i inne p\u0142yny ustrojowe zaczynaj\u0105 nap\u0142ywa\u0107 w kierunku g\u0142owy. Mo\u017ce to powodowa\u0107 uczucie zatkania i b\u00f3le g\u0142owy. Bez oporu grawitacji ko\u015bci i mi\u0119\u015bnie mog\u0105 os\u0142abn\u0105\u0107. Aby zachowa\u0107 dobr\u0105 kondycj\u0119, musz\u0105 codziennie \u0107wiczy\u0107 przez kilka godzin. Dzi\u0119ki temu szybciej wracaj\u0105 do formy po powrocie na Ziemi\u0119.<\/p>\n

W promie kosmicznym lub na stacji kosmicznej nie ma poj\u0119cia \u201eg\u00f3ra\u201d ani \u201ed\u00f3\u0142\u201d. Nie ma r\u00f3\u017cnicy mi\u0119dzy pod\u0142og\u0105 a sufitem. Mo\u017ce to powodowa\u0107 md\u0142o\u015bci u astronaut\u00f3w, dop\u00f3ki nie przyzwyczaj\u0105 si\u0119 do tej dziwnej sytuacji.<\/p>","protected":false},"excerpt":{"rendered":"
