Nobena od teh dejavnosti ni mogo\u010da v orbiti.<\/p>\n<\/div>\n<p>Ko vesoljsko plovilo dose\u017ee orbito, se zdi, da je vse v njem v brezte\u017enosti. Vse (ali kdorkoli), kar ni pritrjeno, bo lebdelo.<\/p>\n<p>Astronavti prvi\u010d ob\u010dutijo u\u010dinek brezte\u017enosti, ko se izklopijo raketni motorji. Takoj za\u010dnejo lebdeti, pri \u010demer jih zadr\u017eujejo le varnostni pasovi. Zaradi brezte\u017enosti se astronavti zdijo izjemno mo\u010dni. Lahko dvignejo predmete, ki bi bili na Zemlji prete\u017eki, da bi jih lahko premaknili. Vendar pa obstajajo tudi nekatere slabosti.<\/p>\n<p>Brez vpliva gravitacije se kri in druge telesne teko\u010dine za\u010dnejo pretakati proti glavi. To lahko povzro\u010di ob\u010dutek zama\u0161enosti in glavobole. Ker ni gravitacije, proti kateri bi se morali upirati, lahko kosti in mi\u0161ice oslabijo. Da bi ostali v formi, morajo vsak dan vaditi ve\u010d ur. Tako se lahko hitreje opomorejo, ko se vrnejo na Zemljo.<\/p>\n<p>V vesoljski ladji ali vesoljski postaji ni zgoraj ali spodaj. Ni razlike med tlemi in stropom. Zaradi tega se lahko astronavtom slabo naredi, dokler se ne navadijo na to nenavadno razporeditev.<\/p>","protected":false},"excerpt":{"rendered":"<p>Our everyday lives involve such activities as sitting, walking, picking up things from the ground and lying in bed.
