Na za\u010d\u00e1tku tohoto t\u00fddne astronauti Samantha Cristoforettiov\u00e1 a Butch Wilmore zachytili kosmickou lo\u010f Dragon, kter\u00e1 dorazila k Mezin\u00e1rodn\u00ed vesm\u00edrn\u00e9 stanici s \u010derstv\u00fdmi z\u00e1sobami a nov\u00fdmi experimenty pro \u0161est astronaut\u016f.<\/p>\n<\/div>\n

Oba astronauti vyu\u017eili obrovsk\u00e9 robotick\u00e9 rameno p\u0159ipevn\u011bn\u00e9 k vn\u011bj\u0161ku vesm\u00edrn\u00e9 stanice, aby zachytili kosmickou lo\u010f a udr\u017eeli ji na m\u00edst\u011b b\u011bhem vykl\u00e1dky.<\/p>\n

Materi\u00e1ly, kter\u00e9 Dragon p\u0159ivezl, byly p\u0159ev\u00e1\u017en\u011b suroviny pro nov\u00e9 experimenty, kter\u00e9 astronauti provedou, v\u010detn\u011b drobn\u00fdch bun\u011bk odebran\u00fdch z ovocn\u00fdch mu\u0161ek, ploch\u00fdch \u010derv\u016f, m\u011bkk\u00fd\u0161\u016f a dokonce i lid\u00ed.<\/p>\n

Jednou z prvn\u00edch v\u011bc\u00ed, kter\u00e9 byly vylo\u017eeny, byl experiment, jen\u017e vy\u017eaduje rychlou reakci astronaut\u016f. Kdy\u017e se lid\u00e9 nach\u00e1zej\u00ed ve vesm\u00edru, jejich imunitn\u00ed syst\u00e9m (tedy ta \u010d\u00e1st t\u011bla, kter\u00e1 n\u00e1s chr\u00e1n\u00ed p\u0159ed nemocemi) nefunguje tak dob\u0159e jako na Zemi. Abychom l\u00e9pe pochopili, pro\u010d tomu tak je, vyslali v\u011bdci na palubu lodi Dragon lidsk\u00e9 imunitn\u00ed bu\u0148ky.<\/p>\n

Drak se p\u0159ibli\u017euje k ISS<\/figcaption><\/figure>\n

Tyto bu\u0148ky byly odebr\u00e1ny z \u010derstv\u00e9 lidsk\u00e9 krve a mimo ni p\u0159e\u017eij\u00ed pouze 120 hodin! To znamen\u00e1, \u017ee astronauti mus\u00ed pracovat velmi rychle, aby stihli sv\u00e9 experimenty v\u010das dokon\u010dit. Po dvoudenn\u00edm letu na lodi Dragon bylo nutn\u00e9 bu\u0148ky co nejd\u0159\u00edve um\u00edstit do inkub\u00e1toru. Dal\u0161\u00edm krokem je vyvol\u00e1n\u00ed p\u0159irozen\u00fdch obrann\u00fdch reakc\u00ed bun\u011bk proti nemocem. Pot\u00e9 budou zmra\u017eeny a p\u0159ipraveny k odesl\u00e1n\u00ed zp\u011bt na Zemi k dal\u0161\u00ed anal\u00fdze.<\/p>\n

Astronauti tak\u00e9 vyvolaj\u00ed um\u011blou infekci, aby aktivovali imunitn\u00ed bu\u0148ky odebran\u00e9 z jin\u00fdch \u017eiv\u00fdch organism\u016f, v\u010detn\u011b krys a mu\u0161l\u00ed. Pot\u00e9 budou zkoumat, jak se tyto bu\u0148ky chovaj\u00ed ve stavu bezt\u00ed\u017ee, v norm\u00e1ln\u00ed gravitaci na Zemi a v um\u011bl\u00e9 gravitaci ve vesm\u00edru.<\/p>\n

T\u00edmto zp\u016fsobem se sna\u017e\u00ed zjistit, zda je p\u0159\u00ed\u010dinou zpomalen\u00e9ho imunitn\u00edho syst\u00e9mu ve vesm\u00edru n\u00edzk\u00e1 gravitace, \u010di vliv nebezpe\u010dn\u00e9ho kosmick\u00e9ho z\u00e1\u0159en\u00ed \u2013 nebo dokonce kombinace obou faktor\u016f!<\/p>\n
