Za\u010diatok cesty Lucy k Jupiteru<\/h3>\n

Sondu do vesm\u00edru vyniesla raketa Atlas V<\/strong>\u00a0spolo\u010dnosti United Launch Alliance (ULA). ULA je spolo\u010dn\u00fd podnik spolo\u010dnost\u00ed Boeing a\u00a0Lockheed Martin. Raketa Atlas V od\u0161tartovala v\u00a0sobotu o\u00a011:34<\/strong> n\u00e1\u0161ho \u010dasu. I\u0161lo o\u00a0100. \u0161tart z\u00a0vesm\u00edrneho \u0161tartovacieho komplexu Cape Caneveral 41. Pribli\u017ene 58 min\u00fat po \u0161tarte bola sonda oddelen\u00e1 od druh\u00e9ho stup\u0148a rakety a\u00a0za\u010dala svoju cestu na Jupiter.<\/p>\n

Po oddelen\u00ed od rakety sonda automaticky rozvinula svoje sol\u00e1rne panely, \u010do trvalo zhruba 20 min\u00fat. Sol\u00e1rne panely<\/strong> sondy Lucy s\u00fa ve\u013emi ve\u013ek\u00e9 (ich \u0161\u00edrka je a\u017e 7,3 metra<\/strong>), nako\u013eko sa sonda bude pohybova\u0165 ve\u013emi \u010faleko od Slnka pri obe\u017enej dr\u00e1he Jupitera. Jej trajekt\u00f3ria ju dokonca dostane tak \u010faleko od Slnka, kam sa e\u0161te \u017eiadna kozmick\u00e1 lo\u010f poh\u00e1\u0148an\u00e1 sol\u00e1rnou energiou nedostala.<\/p>\n

Po rozvinut\u00ed sol\u00e1rnych panelov sonda upravila svoju orient\u00e1ciu tak, aby nasmerovala svoje sol\u00e1rne panely oproti Slnku a\u00a0svoju ant\u00e9nu namierila na Zem. Svoj prv\u00fd sign\u00e1l na Zem vyslala<\/strong> Lucy zo svojej ant\u00e9ny o 12:40<\/strong>.<\/p>\n Let rakety Atlas V so sondou Lucy [NASA]\n

\u010co je cie\u013eom misie?<\/h3>\n

Sonda Lucy mieri k\u00a0asteroidom obiehaj\u00facim Slnko po rovnakej dr\u00e1he ako plan\u00e9ta Jupiter. NASA uviedla, \u017ee tr\u00f3jske asteroidy Jupitera s\u00fa zhluky vesm\u00edrnych horn\u00edn, ktor\u00e9 ostali po sformovan\u00ed plan\u00e9t<\/strong>. Preto sa vedci domnievaj\u00fa, \u017ee n\u00e1m tieto tr\u00f3jske asteroidy m\u00f4\u017eu poskytn\u00fa\u0165 \u010fal\u0161ie inform\u00e1cie o\u00a0vzniku na\u0161ej slne\u010dnej s\u00fastavy<\/strong>.<\/p>\n

NASA vyhradila na misiu okolo 981 mili\u00f3nov dol\u00e1rov<\/strong>. Lucy meria na \u0161\u00edrku okolo 14 metrov<\/strong>, ale v\u00e4\u010d\u0161iu \u010das\u0165 z\u00a0toho zaberaj\u00fa obrovsk\u00e9 sol\u00e1rne panely. Samotn\u00e9 telo sondy, bez sol\u00e1rnych panelov, sa svojou ve\u013ekos\u0165ou viac podob\u00e1 na chladni\u010dku.<\/p>\n

Sonda Lucy sa pohybuje po komplikovanej trajekt\u00f3rii<\/strong>. Nasleduj\u00facich \u0161es\u0165 rokov bude putova\u0165 po slne\u010dnej s\u00fastave, pri\u010dom dvakr\u00e1t obehne okolo Zeme, aby jej po\u010das letu pomohla zemsk\u00e1 gravit\u00e1cia dosta\u0165 sa k\u00a0tr\u00f3jskym asteroidom Jupitera. Je to prv\u00e1 misia jednej kozmickej lode, ktor\u00e1 sk\u00fama hne\u010f nieko\u013eko r\u00f4znych asteroidov.<\/p>\n Ciele misie [NASA]\n

12-ro\u010dn\u00e1 misia<\/h3>\n

Po\u010das tejto 12 rokov trvaj\u00facej misie by mala sonda prejs\u0165 celkovo okolo siedmich tr\u00f3jskych asteroidov<\/strong>, ktor\u00e9 presk\u00fama v s\u00e9ri\u00ed preletov v rokoch 2027 a\u017e 2033. Najv\u00e4\u010d\u0161\u00ed z asteroidov m\u00e1 v priemere 95 kilometrov. Sonda sa k nim pribl\u00ed\u017ei na vzdialenos\u0165 men\u0161iu ako 970 kilometrov od ich povrchu. Z tejto vzdialenosti sonda vyhotov\u00ed fotografie a pok\u00fasi sa ur\u010di\u0165 ich zlo\u017eenie, geol\u00f3giu, hustotu a \u0161trukt\u00faru<\/strong>. Z tohto d\u00f4vodu je sonda vybaven\u00e1 nieko\u013ek\u00fdmi kamerami spolu s teplotn\u00fdmi a infra\u010derven\u00fdmi senzormi. K svojmu prv\u00e9mu cie\u013eu sa sonda dostane u\u017e v roku 2025. Bude n\u00edm mal\u00fd asteroid medzi Marsom a Jupiterom pomenovan\u00fd Donaldjohanson. Pr\u00e1ve na \u0148om si sonda otestuje svoje senzory.<\/p>\n

Pre\u010do sonda Lucy?<\/h3>\n

Sonda Lucy bola pomenovan\u00e1 pod\u013ea objavu<\/strong> 3,2 mili\u00f3na rokov starej skamenenej kostry predka \u010dloveka<\/strong> Lucy v\u00a0Eti\u00f3pii v\u00a0roku 1974. Tento objav poskytol k\u013e\u00fa\u010dov\u00e9 poznatky o\u00a0evol\u00facii \u010dloveka. Podobne aj teraz vedci v NASA d\u00fafaj\u00fa, \u017ee sa im pomocou sondy Lucy podar\u00ed z\u00edska\u0165 nov\u00e9 inform\u00e1cie a\u00a0objasni\u0165 vznik na\u0161ej slne\u010dnej s\u00fastavy. Lucy je u\u017e 13. misiou v\u00a0programe NASA Discovery<\/strong>.<\/p>\n

NASA by po poslednom prelete mohla povoli\u0165 pred\u013a\u017eenie misie a\u00a0pomocou sondy \u010falej sk\u00fama\u0165 \u010fal\u0161ie asteroidy alebo nebesk\u00e9 teles\u00e1. To v\u0161ak bude z\u00e1visie\u0165 od technick\u00e9ho stavu sondy.<\/p>\n
