Druh\u00fd \u00fasp\u011b\u0161n\u00fd zku\u0161ebn\u00ed let megarakety Starship za sebou se uskute\u010dnil ve \u010dtvrtek, co\u017e dokazuje, \u017ee spole\u010dnost p\u0159ech\u00e1z\u00ed od chaotick\u00fdch experiment\u016f k n\u011b\u010demu, co p\u0159ipom\u00edn\u00e1 spolehlivost. Ale \u0161ampa\u0148sk\u00e9 je\u0161t\u011b neotv\u00edrejte. Jedna \u010d\u00e1st mise byla v kou\u0159i \u2013 doslova. <\/p>\n
Poj\u010fme se bl\u00ed\u017ee pod\u00edvat na to, co se stalo b\u011bhem tohoto kl\u00ed\u010dov\u00e9ho testu, pro\u010d je selh\u00e1n\u00ed boosteru m\u00e9n\u011b v\u00fdznamn\u00e9, ne\u017e by se mohlo zd\u00e1t, a co to znamen\u00e1 pro m\u011bs\u00ed\u010dn\u00ed planety NASA. <\/p>\n
Hv\u011bzdn\u00e1 lo\u010f odstartovala t\u011bsn\u011b po 18:50 ET z hv\u011bzdn\u00e9 z\u00e1kladny v Boc Chica v Texasu. Spustila na vrcholu posilova\u010de Super Heavy V3. <\/p>\n
Dv\u011b a p\u016fl minuty \u0161lo v\u0161e podle pl\u00e1nu. Urychlova\u010d se odd\u011blil od horn\u00edho stupn\u011b, jak bylo zam\u00fd\u0161leno. Pot\u00e9 se obr\u00e1til zp\u011bt k Mexick\u00e9mu z\u00e1livu na zp\u00e1te\u010dn\u00ed cestu. <\/p>\n
C\u00edl? Bodov\u00e9 p\u0159ist\u00e1n\u00ed. <\/p>\n
Realita? Ohniv\u00e1 koule. <\/p>\n
Po\u0161kozen\u00fd p\u0159ist\u00e1vac\u00ed syst\u00e9m. Z\u0159\u00edtil se do vody a zp\u016fsobil velkolepou explozi. Pro\u010d se tedy mise naz\u00fdv\u00e1 \u00fasp\u011b\u0161n\u00e1? <\/p>\n
\nHorn\u00ed stupe\u0148, tedy samotn\u00e1 raketa Starship, vstoupila na ob\u011b\u017enou dr\u00e1hu. To je ta nejt\u011b\u017e\u0161\u00ed \u010d\u00e1st. <\/p>\n<\/blockquote>\n
P\u0159esto\u017ee se boosteru nepoda\u0159ilo p\u0159ist\u00e1t, n\u00e1klad splnil sv\u016fj prim\u00e1rn\u00ed \u00fakol. Tento rozd\u00edl je z\u00e1sadn\u00ed pro pochopen\u00ed cesty hv\u011bzdn\u00e9 lodi k provozn\u00edmu stavu. Posilova\u010d je navr\u017een pro op\u011btovn\u00e9 pou\u017eit\u00ed, ale prioritou je nyn\u00ed dostat lo\u010f do vesm\u00edru. <\/p>\n
Testy satelit\u016f, kamer a motor\u016f<\/h3>\n
Hv\u011bzdn\u00e1 lo\u010f nebyla ve vesm\u00edru sama. Vynesla 20 dru\u017eic Starlink V3<\/strong>. <\/p>\n
Toto nen\u00ed jen n\u00e1hodn\u00fd n\u00e1klad. Jedn\u00e1 se o stejn\u00e1 vozidla, kter\u00e1 SpaceX pl\u00e1nuje pou\u017e\u00edt pro svou rozs\u00e1hlou orbit\u00e1ln\u00ed internetovou s\u00ed\u0165. Pro tento test slou\u017eily dvoj\u00ed funkci:<\/p>\n
\n
- N\u011bkter\u00e9 satelity byly vybaveny kamerami. <\/li>\n
- Tyto kamery poskytly in\u017een\u00fdr\u016fm na Zemi sn\u00edmky tepeln\u00e9ho \u0161t\u00edtu b\u011bhem letu. <\/li>\n<\/ul>\n
Pro\u010d kontrolovat tepeln\u00fd \u0161t\u00edt? Proto\u017ee p\u0159e\u017eit\u00ed op\u011btovn\u00e9ho vstupu je pro Starship hlavn\u00ed v\u00fdzvou. <\/p>\n
Po dokon\u010den\u00ed sv\u00e9ho \u00fakolu se satelity pokusily nav\u00e1zat laserovou komunikaci se st\u00e1vaj\u00edc\u00ed s\u00edt\u00ed. Pot\u00e9 byly opu\u0161t\u011bny a sp\u00e1leny v zemsk\u00e9 atmosf\u00e9\u0159e. Jen testovali kon\u011b, a ne st\u00e1l\u00e9 obyvatele ob\u011b\u017en\u00e9 dr\u00e1hy. <\/p>\n
Vylep\u0161en\u00ed motoru a splashdown<\/h3>\n
Tento let trval hodinu a p\u011bt minut. To bylo p\u0159epl\u00e1nov\u00e1no z p\u0159edchoz\u00edho t\u00fddne, ale po startu raketa dokon\u010dila svou plnou dr\u00e1hu letu. <\/p>\n
Starship od sv\u00e9ho kv\u011btnov\u00e9ho testovac\u00edho letu prok\u00e1zala jasn\u00e1 zlep\u0161en\u00ed. Probl\u00e9my s motory Raptor, kter\u00e9 se objevily b\u011bhem t\u00e9to mise (kdy\u017e se jeden z motor\u016f p\u0159ed\u010dasn\u011b vypnul), byly vy\u0159e\u0161eny. B\u011bhem tohoto letu kosmick\u00e1 lo\u010f \u00fasp\u011b\u0161n\u011b znovu zap\u00e1lila jeden ze sv\u00fdch \u0161esti motor\u016f pro kr\u00e1tk\u00e9 sp\u00e1len\u00ed ve vesm\u00edru. <\/p>\n
Hv\u011bzdn\u00e1 lo\u010f, kter\u00e1 z\u016fstala sama, dokon\u010dila svou cestu a \u0161plouchla v Indick\u00e9m oce\u00e1nu severn\u011b od Austr\u00e1lie. <\/p>\n
P\u0159i pono\u0159en\u00ed do vody se trochu rozho\u0159el. <\/p>\n
Ale p\u0159e\u017eila. <\/p>\n
Pro\u010d je to d\u016fle\u017eit\u00e9 pro program Artemis<\/h3>\n
SpaceX chce nahradit Falcon 9 hv\u011bzdnou lod\u00ed jako hlavn\u00edm tahounem. S nosnost\u00ed 100 tun na ob\u011b\u017enou dr\u00e1hu m\u016f\u017ee Starship vyn\u00e9st na ob\u011b\u017enou dr\u00e1hu mnohem v\u00edce satelit\u016f Starlink na jeden start ne\u017e star\u0161\u00ed raketa. <\/p>\n
Ale s\u00e1zky jsou zde vy\u0161\u0161\u00ed ne\u017e jen \u0161irokop\u00e1smov\u00fd internet.<\/p>\n
NASA cel\u00fd proces bedliv\u011b sleduje. Vesm\u00edrn\u00e1 agentura douf\u00e1, \u017ee v r\u00e1mci programu Artemis pou\u017eije lun\u00e1rn\u00ed verzi Starship pro m\u011bs\u00ed\u010dn\u00ed mise<\/strong>. Pokud SpaceX dodr\u017e\u00ed term\u00edn, lid\u00e9 by mohli poprv\u00e9 po v\u00edce ne\u017e 50 letech vstoupit na M\u011bs\u00edc ji\u017e v roce 2028.<\/p>\n
Pro tuto roli jsou i konkurenti. Dohled z b\u0159ezna zaznamenal, \u017ee SpaceX zaost\u00e1v\u00e1. NASA tak\u00e9 financuje Blue Origin na v\u00fdvoj vlastn\u00edho lun\u00e1rn\u00edho p\u0159ist\u00e1vac\u00edho modulu jako z\u00e1lohy. <\/p>\n
Tento test nazna\u010duje, \u017ee SpaceX zmen\u0161uje mezeru. Ano, urychlova\u010d spadl. Ale lo\u010f vzl\u00e9tla. Satelity byly vypu\u0161t\u011bny. Motor byl znovu nastartov\u00e1n. <\/p>\n
Jeden d\u00edlek skl\u00e1da\u010dky st\u00e1le chyb\u00ed. Posilova\u010d mus\u00ed p\u0159ist\u00e1t.
