Nyn\u00ed na to upozornil britsk\u00fd server Metro<\/a>. Plodinu p\u0159ezd\u00edvanou \u201eSpudnik-1\u201c (nikoli Sputnik) popsal takto: \u201eVzal jsem si brambory na misi Expedition 72\u00a0pro svou vesm\u00edrnou zahradu, co\u017e byla aktivita, kter\u00e9 jsem se v\u011bnoval ve voln\u00e9m \u010dase.\u201c<\/p>\n

\u201eToto je ran\u00e1 fialov\u00e1 brambora, dopln\u011bn\u00e1 kouskem such\u00e9ho zipu s\u00a0h\u00e1\u010dky, aby ji bylo mo\u017en\u00e9 ukotvit v\u00a0m\u00e9m improvizovan\u00e9m ter\u00e1riu s\u00a0p\u011bstebn\u00edm osv\u011btlen\u00edm,\u201c sd\u011blil 70let\u00fd Pettit, nejstar\u0161\u00ed aktivn\u00ed astronaut NASA.<\/p>\n

Ne v\u0161ichni na internetu ale byli v\u00fdsledkem Pettitova vesm\u00edrn\u00e9ho experimentu nad\u0161eni. Jeden z\u00a0komentuj\u00edc\u00edch nap\u0159\u00edklad napsal: \u201eUp\u0159\u00edmn\u011b jsem si myslel, \u017ee je to n\u011bjak\u00e9 l\u00edhnouc\u00ed se vejce.\u201c<\/p>\n

<\/a><\/p>\n

Z brambory s\u00a0mimozemsk\u00fdm vzhledem vyr\u016fstala nezvykle vypadaj\u00edc\u00ed fialov\u00e1 vl\u00e1kna, co\u017e Pettit vysv\u011btlil jako d\u016fsledek nulov\u00e9 gravitace.<\/p>\n

\u201eKo\u0159eny by bez vlivu gravitace rostly v\u0161emi sm\u011bry a\u00a0v\u0161echny rostliny, kter\u00e9 jsem kdy ve vesm\u00edru p\u011bstoval, rostly mnohem pomaleji, ne\u017e by rostly na Zemi,\u201c uvedl.<\/p>\n

\u201eBrambory pat\u0159\u00ed mezi nejefektivn\u011bj\u0161\u00ed rostliny z\u00a0hlediska pom\u011bru jedl\u00e9 v\u00fd\u017eivy k\u00a0celkov\u00e9 hmotnosti rostliny (v\u010detn\u011b ko\u0159en\u016f),\u201c oz\u0159ejmil d\u016fvod takov\u00e9ho p\u011bstov\u00e1n\u00ed Pettit, kter\u00fd na ISS naposledy pob\u00fdval od z\u00e1\u0159\u00ed 2024\u00a0do dubna 2025<\/a>.<\/p>\n

Ostatn\u011b jak poznamenal Andy Weir ve sv\u00e9 knize \u201eMar\u0165an\u201c, brambory budou m\u00edt sv\u00e9 m\u00edsto v\u00a0budouc\u00edm pr\u016fzkumu vesm\u00edru, p\u0159ipomn\u011bl d\u00e1le astronaut.<\/p>\n
