Oma 10-aastase teekonna jooksul s\u00fcgavas kosmoses k\u00fclastab Rosetta kaks korda peamist asteroidi v\u00f6\u00f6d, mis asub Marsi ja Jupiteri vahel. Selle esimene ajalooline kohtumine asteroidiga toimub 5. septembril kell 20:58 CEST (Kesk-Euroopa suveaeg).<\/p>\n<\/div>\n<p>Alates 2004. aasta m\u00e4rtsis toimunud stardist on Rosetta l\u00e4binud umbes 3 700 miljonit km. Praegu asub ta P\u00e4ikesest rohkem kui kaks korda nii kaugel kui Maa. Kosmoselaev on juba kaks korda m\u00f6\u00f6dunud Maast ja Marsist, kuid m\u00f6\u00f6dalend v\u00e4ikesest kivist asteroidist nimega Steins pakub esimest t\u00f5elist v\u00f5imalust kasutada selle teaduslikke instrumente.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1323\" data-credit=\"ESA, image by C.Carreau\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2008\/09\/Artist_s_impression_of_asteroid_2867_Steins2\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2008\/09\/artist_s_impression_of_asteroid_2867_steins2\/17884620-2-eng-GB\/Artist_s_impression_of_asteroid_2867_Steins.jpg\" alt=\"Artist\u2019s impression of asteroid (2867) Steins\"><figcaption>Kunstniku kujutis asteroidist (2867) Steins<\/figcaption><\/figure>\n<p>Rosetta lendab Steinsist m\u00f6\u00f6da kiirusega umbes 31 000 km tunnis. Alates augusti algusest on selle kaameratega tehtud pilte kasutatud Steinsi j\u00e4lgimiseks ja selle asukoha t\u00e4pseks m\u00e4\u00e4ramiseks. See v\u00f5imaldab kosmoselaeval m\u00f6\u00f6duda sihtm\u00e4rgist vaid 800 km kauguselt. Kahjuks peavad ESA Euroopa kosmosekeskuse (European Space Operations Centre) juhtijad Darmstadtis, Saksamaal, ootama kuni kella 22.23 Kesk-Euroopa suveaja j\u00e4rgi, et saada esimene side Rosettaga ja kinnitus m\u00f6\u00f6dalennu \u00f5nnestumise kohta.<\/p>\n<p>Steins avastati 1969. aastal ja selle l\u00e4bim\u00f5\u00f5t on vaid m\u00f5ni kilomeeter. Selle heleduse korrap\u00e4rased muutused n\u00e4itavad, et see p\u00f6\u00f6rleb umbes kord iga 6 tunni j\u00e4rel. Teadlased soovivad selle v\u00e4ikese maailma kohta rohkem teada saada, sest tegemist on suhteliselt haruldase t\u00fc\u00fcpi asteroidiga. Steinsi-t\u00fc\u00fcpi objektid on planeetide s\u00fcnni j\u00e4\u00e4gid, mis p\u00e4rinevad 4,5 miljardit aastat tagasi. Neid uurides saame rohkem teada Maa ja teiste P\u00e4ikeses\u00fcsteemi planeetide tekkimise kohta.<\/p>","protected":false},"excerpt":{"rendered":"<p>ESA\u2019s Rosetta spacecraft is on its way to a rendezvous with a comet in 2014.
