V za\u010detku tega tedna sta astronavta Samantha Cristoforetti in Butch Wilmore prestregla vesoljsko plovilo Dragon, ko je prispelo na Mednarodno vesoljsko postajo s sve\u017eimi zalogami in novimi poskusi za \u0161est astronavtov.<\/p>\n<\/div>\n

Oba sta za zajem vesoljskega plovila in njegovo zadr\u017eevanje na mestu med raztovarjanjem uporabila ogromno robotska roko, pritrjeno na zunanji strani vesoljske postaje.<\/p>\n

Materiali, ki jih je prinesel Dragon, so bili ve\u010dinoma sestavine za nove poskuse, ki jih bodo izvedli astronavti, vklju\u010dno z drobnimi celicami, odvzetimi iz sadnih mu\u0161ic, plo\u0161\u010datih \u010drvov, \u0161koljk in celo ljudi.<\/p>\n

Ena od prvih stvari, ki so jih raztovorili, je bil poskus, ki od astronavtov zahteva hitro ukrepanje. Ko so ljudje v vesolju, njihov imunski sistem (to je del na\u0161ega telesa, ki nas \u0161\u010diti pred boleznimi) ne deluje tako dobro kot na Zemlji. Da bi la\u017eje razumeli, zakaj je tako, so raziskovalci na krov ladje Dragon poslali \u010dlove\u0161ke imunske celice.<\/p>\n

Te celice so bile izolirane iz sve\u017ee \u010dlove\u0161ke krvi in zunaj nje pre\u017eivijo le 120 ur! To pomeni, da morajo astronavti delati zelo hitro, da svoje poskuse zaklju\u010dijo pravo\u010dasno. Po dvodnevnem poletu z raketo Dragon je bilo treba celice \u010dim prej umestiti v inkubator. Naslednji korak je spro\u017eitev naravnih odzivov celic proti boleznim. Nato bodo zamrznjene in pripravljene za po\u0161iljanje nazaj na Zemljo za nadaljnjo analizo.<\/p>\n

Astronavti bodo prav tako ustvarili umetno oku\u017ebo, da bi aktivirali imunske celice, odvzete drugim \u017eivim bitjem, vklju\u010dno s podganami in \u0161koljkami. Nato bodo preu\u010devali, kako se celice obna\u0161ajo v brezte\u017enosti, v normalni gravitaciji na Zemlji in v umetni gravitaciji v vesolju.<\/p>\n

S tem \u017eelijo ugotoviti, ali je vzrok za upo\u010dasnjeno delovanje imunskega sistema v vesolju nizka gravitacija ali vpliv nevarnih kozmi\u010dnih \u017earkov \u2013 ali morda celo kombinacija obeh!<\/p>\n
