Kosmick\u00fd teleskop Jamese Webba p\u0159ekonal jednu z hlavn\u00edch p\u0159ek\u00e1\u017eek nasazen\u00ed<\/h2>\n\n

Kosmick\u00fd teleskop Jamese Webba (JWST) \u00fasp\u011b\u0161n\u011b rozvinul svou slune\u010dn\u00ed clonu o velikosti tenisov\u00e9ho kurtu, co\u017e p\u0159edstavuje v\u00fdznamn\u00fd miln\u00edk v jeho nasazen\u00ed. Slune\u010dn\u00ed clona je kl\u00ed\u010dovou sou\u010d\u00e1st\u00ed teleskopu, proto\u017ee chr\u00e1n\u00ed jeho citliv\u00e9 p\u0159\u00edstroje p\u0159ed teplem ze Slunce.<\/p>\n\n

Slune\u010dn\u00ed clona: Slo\u017eit\u00e9 a riskantn\u00ed nasazen\u00ed<\/h3>\n\n

Nasazen\u00ed slune\u010dn\u00ed clony bylo nejriskantn\u011bj\u0161\u00edm a nejslo\u017eit\u011bj\u0161\u00edm aspektem nasazen\u00ed JWST. Slune\u010dn\u00ed clona se skl\u00e1d\u00e1 z p\u011bti ultratenk\u00fdch f\u00f3liov\u00fdch vrstev, kter\u00e9 jsou nata\u017eeny do obd\u00e9ln\u00edkov\u00e9ho tvaru. Vn\u011bj\u0161\u00ed vrstva slune\u010dn\u00ed clony m\u016f\u017ee dos\u00e1hnout teploty 230 stup\u0148\u016f Fahrenheita, zat\u00edmco nejvnit\u0159n\u011bj\u0161\u00ed vrstva m\u016f\u017ee klesnout na -394 stup\u0148\u016f Fahrenheita.<\/p>\n\n

Aby bylo mo\u017en\u00e9 slune\u010dn\u00ed clonu \u00fasp\u011b\u0161n\u011b rozvinout, musely tis\u00edce d\u00edl\u016f spolupracovat s p\u0159esnost\u00ed. F\u00e1ze nap\u00edn\u00e1n\u00ed membr\u00e1ny p\u0159i nasazen\u00ed byla obzvl\u00e1\u0161t\u011b n\u00e1ro\u010dn\u00e1, proto\u017ee existuj\u00ed komplexn\u00ed interakce mezi konstrukcemi, nap\u00ednac\u00edmi mechanismy, kabely a membr\u00e1nami.<\/p>\n\n

V\u00fdznam slune\u010dn\u00ed clony<\/h3>\n\n

Slune\u010dn\u00ed clona je z\u00e1sadn\u00ed pro spr\u00e1vnou funkci JWST. Teleskop pracuje p\u0159i extr\u00e9mn\u011b n\u00edzk\u00fdch teplot\u00e1ch a slune\u010dn\u00ed clona zabra\u0148uje, aby se teplo ze Slunce dostalo k p\u0159\u00edstroj\u016fm teleskopu. Bez slune\u010dn\u00ed clony by teleskop nemohl shroma\u017e\u010fovat data.<\/p>\n\n

T\u00fdm, kter\u00fd stoj\u00ed za nasazen\u00edm<\/h3>\n\n

\u00dasp\u011b\u0161n\u00e9 nasazen\u00ed slune\u010dn\u00ed clony je d\u016fkazem dovednost\u00ed a vynal\u00e9zavosti t\u00fdmu, kter\u00fd stoj\u00ed za JWST. T\u00fdm ne\u00fanavn\u011b pracoval na n\u00e1vrhu, konstrukci a testov\u00e1n\u00ed slune\u010dn\u00ed clony a jejich \u00fasil\u00ed se vyplatilo.<\/p>\n\n

Budoucnost JWST<\/h3>\n\n

Po \u00fasp\u011b\u0161n\u00e9m nasazen\u00ed slune\u010dn\u00ed clony je JWST o krok bl\u00ed\u017ee k tomu, aby se stal pln\u011b funk\u010dn\u00ed. O\u010dek\u00e1v\u00e1 se, \u017ee teleskop za\u010dne po\u0159izovat sv\u00e9 prvn\u00ed sn\u00edmky toto l\u00e9to. Tyto sn\u00edmky poskytnou v\u011bdc\u016fm bezprecedentn\u00ed pohledy na vesm\u00edr a pomohou n\u00e1m pochopit p\u016fvod kosmu.<\/p>\n\n

Postup nasazen\u00ed<\/h3>\n\n
    \n
  1. Slune\u010dn\u00ed clona byla slo\u017eena tak, aby se ve\u0161la do rakety, kter\u00e1 vypustila JWST.<\/li>\n
  2. Trvalo osm dn\u00ed, ne\u017e byla slune\u010dn\u00ed clona pln\u011b rozvinuta a napnuta.<\/li>\n
  3. Posledn\u00ed vrstva slune\u010dn\u00ed clony byla zaji\u0161t\u011bna v \u00fater\u00fd kolem poledne.<\/li>\n
  4. Teleskop za\u010dal konfigurovat sv\u00e9 sekund\u00e1rn\u00ed zrcadlo, kter\u00e9 zaklaplo na m\u00edsto ve st\u0159edu.<\/li>\n
  5. Hlavn\u00ed zrcadlo se za\u010dne rozkl\u00e1dat v pr\u016fb\u011bhu n\u011bkolika n\u00e1sleduj\u00edc\u00edch dn\u016f.<\/li>\n
  6. Jakmile bude v\u0161ech 18 d\u00edl\u016f hlavn\u00edho zrcadla na sv\u00e9m m\u00edst\u011b, bude trvat asi 100 dn\u00ed, ne\u017e vychladnou.<\/li>\n
  7. V\u011bdci o\u010dek\u00e1vaj\u00ed, \u017ee prvn\u00ed sn\u00edmky z teleskopu obdr\u017e\u00ed toto l\u00e9to.<\/li>\n<\/ol>\n\n
