Uplynulo sedm m\u011bs\u00edc\u016f. Zva\u017ete to dostate\u010dn\u011b, abyste to vydr\u017eeli. <\/p>\n
V p\u00e1tek ve\u010der, kolem 23:30 moskevsk\u00e9ho \u010dasu, SpaceX kone\u010dn\u011b dala v\u011bci do pohybu. Jednalo se o debut Starship verze 3 (V3). Ano, toto je teprve dvan\u00e1ct\u00e1 zkou\u0161ka programu jako celku, ale z\u00e1rove\u0148 je to nejt\u011b\u017e\u0161\u00ed stavba, jakou kdy lidstvo vyneslo do nebe. <\/p>\n
P\u0159edstavte si m\u011b\u0159\u00edtko. Raketa je vysok\u00e1 123 metr\u016f. Vytv\u00e1\u0159\u00ed tah o s\u00edle 8 milion\u016f kilogram\u016f (asi 80 MN). Nen\u00ed to jen mocn\u00e9. Tohle je monstr\u00f3zn\u00ed. <\/p>\n
P\u016fvodn\u011b byl navr\u017een tak, aby byl zcela znovu pou\u017eiteln\u00fd \u2013 teoreticky. Ale ne pro tento let. Posilova\u010d ani lo\u010f se nevr\u00e1tily. V\u0161echno z\u016fstalo tam, ve vesm\u00edru. <\/p>\n
Za\u010d\u00e1tek byl… \u0159ekn\u011bme, \u017ee ne bez n\u011bjak\u00fdch drsn\u00fdch hran. Jeden z t\u0159iat\u0159iceti motor\u016f na posilova\u010di Super Heavy nen\u00ed zap\u00e1len\u00fd. \u0160patn\u011b. To ale pro stroj nebylo \u00fapln\u011b d\u016fle\u017eit\u00e9. Pokra\u010dovala v nab\u00edr\u00e1n\u00ed v\u00fd\u0161ky. <\/p>\n
Do\u0161lo k rozchodu. Posilova\u010d spadl a z\u0159\u00edtil se do Mexick\u00e9ho z\u00e1livu, co\u017e zp\u016fsobilo post\u0159\u00edk\u00e1n\u00ed p\u0159esn\u011b tam, kde bylo pl\u00e1nov\u00e1no. Stejn\u011b jako v u\u010debnici. <\/p>\n
A co lo\u010f? M\u011bl tak\u00e9 probl\u00e9my. P\u0159i stoup\u00e1n\u00ed se zastavil jeden z jeho \u0161esti motor\u016f. SpaceX p\u0159ipustilo, \u017ee kv\u016fli tomu m\u016f\u017ee mise m\u00edrn\u011b ubrat na sv\u00fdch \u00fakolech. Koho to zaj\u00edm\u00e1? Na zemi t\u00fdm zoufale k\u0159i\u010del radost\u00ed. V hang\u00e1ru zah\u0159m\u011bl potlesk. <\/p>\n
Co tam v\u016fbec d\u011blala<\/em>? <\/p>\n Pl\u00e1n byl jednoduch\u00fd. Zah\u00e1jit. Odd\u011blen\u00ed. Splashdown v Indick\u00e9m oce\u00e1nu. P\u0159ipraveno. P\u0159ipraveno. <\/p>\n Pot\u00e9, co vypadl booster, Starship shodila dvacet cvi\u010dn\u00fdch satelit\u016f Starlink. Prost\u011b figur\u00edny. Tr\u00e9ninkov\u00e9 \u201eblanky\u201c ve v\u00fd\u0161ce asi 195 km. A pak spustil dva skute\u010dn\u00e9. Nejsou pro internet. Byly to kamery ur\u010den\u00e9 ke skenov\u00e1n\u00ed tepeln\u00e9 ochrany lodi, kdy\u017e ho\u0159ela atmosf\u00e9rou. <\/p>\n Tento obr\u00e1zek ukazuje pohled na hv\u011bzdnou lo\u010f ve vesm\u00edru, zachycen\u00fd pr\u00e1v\u011b satelitem, kter\u00fd ji pom\u00e1hal pozorovat. <\/p>\n<\/blockquote>\n N\u00e1vrat za\u010dal sedma\u010dty\u0159icet minut po startu. Lo\u010f provedla p\u0159evrat, p\u0159esn\u011b ten man\u00e9vr, p\u0159i kter\u00e9m fanou\u0161ci fyziky v\u017edy zataj\u00ed dech. P\u0159ist\u00e1n\u00ed bylo p\u0159esn\u00e9. <\/p>\n Jared Isaacman, \u0161\u00e9f NASA, \u0159ekl p\u0159ed startem n\u011bkolik mil\u00fdch slov. M\u00ed\u0159\u00ed na rok 2027 pro misi Artemis III, p\u0159i kter\u00e9 se lid\u00e9 skute\u010dn\u011b vr\u00e1t\u00ed na M\u011bs\u00edc. Nebo to alespo\u0148 \u0159\u00edk\u00e1 j\u00edzdn\u00ed \u0159\u00e1d. <\/p>\n “T\u011b\u0161\u00edme se, \u017ee v\u00e1s uvid\u00edme na n\u00edzk\u00e9 ob\u011b\u017en\u00e9 dr\u00e1ze Zem\u011b,” \u0159ekl Isaacman. Mluv\u00ed o ukotven\u00ed kapsle Orion s hv\u011bzdnou lod\u00ed. Snad i s lun\u00e1rn\u00edm modulem Blue Moon. S\u00e1zky jsou neuv\u011b\u0159iteln\u011b vysok\u00e9. <\/p>\n NASA pot\u0159ebuje, aby Starship fungovala. Konkr\u00e9tn\u011b ji pot\u0159ebuj\u00ed k p\u0159eprav\u011b astronaut\u016f z ob\u011b\u017en\u00e9 dr\u00e1hy na m\u011bs\u00ed\u010dn\u00ed povrch do roku 2028, pokud v\u0161e p\u016fjde podle pl\u00e1nu. <\/p>\n Tady ale v\u0161e nen\u00ed tak plynul\u00e9 a bez v\u00fdbuch\u016f. Gener\u00e1ln\u00ed inspekto\u0159i bedliv\u011b sleduj\u00ed. Varovali, \u017ee SpaceX nemus\u00ed term\u00edn dodr\u017eet. Prvn\u00ed testy explodovaly \u2013 doslova. Proces zahrnuje v\u00fdbuchy. V\u0161echno b\u011b\u017e\u00ed pozd\u011b. <\/p>\n Pro\u010d tedy byla tato demonstrace pro Muskovu spole\u010dnost takovou v\u00fdhrou? <\/p>\n Jen proto. Pravd\u011bpodobn\u011b se brzy dostane na ve\u0159ejnost. <\/p>\n Investo\u0159i miluj\u00ed funguj\u00edc\u00ed prototypy.
