Robotick\u00e9 vozidlo Curiosity na Marse za\u017eilo jeden z najbizarnej\u0161\u00edch<\/a> probl\u00e9mov za cel\u00e9 roky svojej slu\u017eby. Pri be\u017enom v\u0155tan\u00ed horniny sa toti\u017e stalo nie\u010do, \u010do technici NASA<\/a> e\u0161te nikdy nevideli. Rover nav\u0155tal kame\u0148, no ke\u010f sa pok\u00fasil od\u00eds\u0165, skala sa ho odmietla pusti\u0165. <\/p>\n

Cel\u00fd incident p\u00f4sobil tak trochu komicky. Curiosity vytiahol robotick\u00e9 rameno, zav\u0155tal sa do mar\u0165anskej horniny a n\u00e1sledne sa pok\u00fasil vrt\u00e1k vytiahnu\u0165 sp\u00e4\u0165. Len\u017ee namiesto toho, aby zostal kus skaly na zemi, zdvihol sa spolu s ramenom cel\u00fd balvan. NASA nesk\u00f4r zverejnila \u010diernobiele z\u00e1bery z kamier rovera, na ktor\u00fdch vid\u00ed\u0161 zvl\u00e1\u0161tny moment celkom detailne. Skala visela priamo na vrt\u00e1ku a Curiosity sa jej nevedel zbavi\u0165 nieko\u013eko dn\u00ed.<\/p>\n

\nPre\u010do ostal kame\u0148 na vrt\u00e1ku doslova prilepen\u00fd?<\/p>\n

Vedci dali hornine meno Atacama. Kame\u0148 meral pribli\u017ene 45 centimetrov a v\u00e1\u017eil okolo 13 kilogramov. Na mar\u0165ansk\u00e9 pomery ne\u0161lo o \u017eiadny gigantick\u00fd balvan, no roveru aj tak poriadne zamotal pl\u00e1ny. Cel\u00fd probl\u00e9m vznikol 25. apr\u00edla, ke\u010f Curiosity pou\u017eil svoj perkus\u00edvny vrt\u00e1k na z\u00edskanie vzorky horniny. Tak\u00e9to v\u0155tanie patr\u00ed medzi jeho najd\u00f4le\u017eitej\u0161ie \u00falohy. Rover rozdrv\u00ed vn\u00fatro skaly na jemn\u00fd pr\u00e1\u0161ok a n\u00e1sledne ho analyzuje priamo na Marse.<\/p>\n

Tentoraz v\u0161ak vrt\u00e1k uviazol v hornine tak pevne, \u017ee sa kame\u0148 doslova prilepil na ochrann\u00fd obal vrt\u00e1ku. NASA priznala, \u017ee nie\u010do podobn\u00e9 e\u0161te neza\u017eila. Vrchn\u00e9 vrstvy horn\u00edn sa pri v\u0155tan\u00ed s\u00edce u\u017e v minulosti l\u00e1mali, no cel\u00fd kus skaly e\u0161te nikdy nezostal visie\u0165 na robotickom ramene. Vedci zatia\u013e presne netu\u0161ia, pre\u010do sa to stalo.<\/p>\n

Jedna z hypot\u00e9z hovor\u00ed o zvl\u00e1\u0161tnom mechanickom zaklinen\u00ed mar\u0165ansk\u00e9ho prachu. Mars pokr\u00fdva jemn\u00fd regolit, teda extr\u00e9mne drobn\u00fd prach a rozdrven\u00e1 hornina, ktor\u00e1 sa pri v\u0155tan\u00ed mohla natla\u010di\u0165 okolo vrt\u00e1ka. Mar\u0165ansk\u00fd regolit m\u00e1 z\u00e1rove\u0148 potenci\u00e1l agres\u00edvne br\u00fasi\u0165, \u010di\u017ee vo vrte mohol vznikn\u00fa\u0165 obrovsk\u00fd odpor.<\/p>\n

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

V \u00fazkom priestore sa mohol prach doslova \u201ezahryzn\u00fa\u0165\u201c medzi kovov\u00e9 \u010dasti a vytvori\u0165 trenie, ktor\u00e9 dr\u017ealo horninu na mieste. Atmosf\u00e9ra Marsu je navy\u0161e v porovnan\u00ed s pozemskou ve\u013emi tenk\u00e1. Dosahuje len pribli\u017ene jedno percento hustoty tej zemskej, tak\u017ee sa tam niektor\u00e9 mechanick\u00e9 javy spr\u00e1vaj\u00fa odli\u0161ne ne\u017e na Zemi.<\/p>\n

To z\u00e1rove\u0148 vysvet\u013euje, pre\u010do nesta\u010dilo oby\u010dajn\u00e9 potiahnutie ramena. Technici museli t\u00fato prachov\u00fa v\u00e4zbu doslova rozbi\u0165 vibr\u00e1ciami. Curiosity<\/a> preto za\u010dal s\u00e9riu opatrn\u00fdch pokusov. Oper\u00e1tori najsk\u00f4r aktivovali vibr\u00e1cie vrt\u00e1ku v n\u00e1deji, \u017ee sa hornina otrasmi uvo\u013en\u00ed. Nepomohlo to. Rover n\u00e1sledne menil polohu ramena a sk\u00fa\u0161al \u010fal\u0161ie vibr\u00e1cie, no Atacama sa st\u00e1le dr\u017eala ako pribit\u00e1.<\/p>\n

Na z\u00e1beroch z NASA cel\u00e1 situ\u00e1cia vyzer\u00e1 trochu absurdne. Nieko\u013ekotonov\u00fd rover stoj\u00ed na pustej plan\u00e9te a nieko\u013eko dn\u00ed z\u00e1pas\u00ed s jedn\u00fdm tvrdohlav\u00fdm kame\u0148om. V skuto\u010dnosti v\u0161ak i\u0161lo o pomerne riskantn\u00fa situ\u00e1ciu. Curiosity funguje na Marse u\u017e od roku 2012 a jeho motory aj mechanick\u00e9 k\u013aby pracuj\u00fa viac ne\u017e 14 rokov v extr\u00e9mnych podmienkach. Ka\u017ed\u00fd pohyb robotick\u00e9ho ramena znamen\u00e1 z\u00e1\u0165a\u017e pre s\u00fa\u010diastky, ktor\u00e9 za\u017eili nekone\u010dn\u00e9 cykly mrazu, prachu a radi\u00e1cie.<\/p>\n

Agres\u00edvnej\u0161\u00ed man\u00e9ver mohol misiu Curiosity ukon\u010di\u0165 pred\u010dasne<\/p>\n

Nakoniec ale padlo rozhodnutie \u00eds\u0165 \u201eall-in\u201c, \u010d\u00edm ale oper\u00e1tori riskovali pomerne ve\u013ea. Kombin\u00e1cia vibr\u00e1ci\u00ed, rot\u00e1cie vrt\u00e1ku a agres\u00edvnej\u0161ieho n\u00e1klonu mohla po\u0161kodi\u0165 motor v robotickom k\u013abe. Ak by sa to stalo, Curiosity by mohol pr\u00eds\u0165 o svoju najd\u00f4le\u017eitej\u0161iu schopnos\u0165, v\u0155tanie horn\u00edn. Pr\u00e1ve preto t\u00edm postupoval ve\u013emi pomaly. <\/p>\n

Z\u00e1rove\u0148 mus\u00edme bra\u0165 do \u00favahy aj to, \u017ee Mars nie je pr\u00e1ve za rohom. Sign\u00e1l medzi Zemou a \u010dervenou plan\u00e9tou let\u00ed pribli\u017ene 10 a\u017e 20 min\u00fat pod\u013ea aktu\u00e1lnej vzdialenosti plan\u00e9t. To znamen\u00e1, \u017ee ke\u010f oper\u00e1tor v Kalifornii poslal roveru pr\u00edkaz na vibr\u00e1cie vrt\u00e1ku, odpove\u010f dostal a\u017e o desiatky min\u00fat nesk\u00f4r. Ka\u017ed\u00fd pokus preto pripom\u00ednal extr\u00e9mne pomal\u00fa hru pokus\u2013odozva. Technici poslali pr\u00edkaz, \u010dakali na vykonanie man\u00e9vru a n\u00e1sledne analyzovali nov\u00e9 sn\u00edmky z Marsu. <\/p>\n

T\u00fdch \u0161es\u0165 dn\u00ed nepredstavovalo len rozm\u00fd\u0161\u013eanie nad rie\u0161en\u00edm, ale hlavne ve\u013emi pomal\u00e9 a opatrn\u00e9 testovanie ka\u017ed\u00e9ho \u010fal\u0161ieho kroku. A\u017e 1. m\u00e1ja pri\u0161iel zlom. Oper\u00e1tori naklonili vrt\u00e1k do ostrej\u0161ieho uhla, rozto\u010dili ho, aktivovali vibr\u00e1cie a z\u00e1rove\u0148 zmenili orient\u00e1ciu robotick\u00e9ho ramena. Toto bol man\u00e9ver, ktor\u00fd vrt\u00e1k uvo\u013enil prakticky okam\u017eite.\u00a0 Skala sa od vrt\u00e1ku odtrhla u\u017e pri prvom pokuse, p\u00e1d v\u0161ak nepre\u017eila. Atacama po dopade na povrch Marsu praskla na viacero kusov.<\/p>\n

\u201eMysleli sme si, \u017ee budeme musie\u0165 sk\u00fasi\u0165 viacero pokusov a cel\u00fd probl\u00e9m sa e\u0161te natiahne o \u010fal\u0161ie dni,\u201c priznali oper\u00e1tori NASA po \u00faspe\u0161nom uvo\u013enen\u00ed vrt\u00e1ku.<\/p>\n

Curiosity n\u00e1sledne obnovil svoju misiu a moment\u00e1lne pokra\u010duje v h\u013eadan\u00ed \u010fal\u0161\u00edch horn\u00edn, ktor\u00e9 by mohli prezradi\u0165 viac o d\u00e1vnej minulosti Marsu<\/a>. Incident s Atacamou v\u0161ak uk\u00e1zal, \u017ee aj po viac ne\u017e desa\u0165ro\u010d\u00ed na cudzej plan\u00e9te dok\u00e1\u017ee jeden oby\u010dajn\u00fd kame\u0148 poriadne potr\u00e1pi\u0165 technol\u00f3giu za miliardy dol\u00e1rov.<\/p>\n
