10 hossz\u00fa \u00e9vnyi utaz\u00e1s ut\u00e1n, amely sor\u00e1n a Naprendszer hossz\u00e1nak t\u00f6bb mint fel\u00e9t tette meg \u00e9s \u00f6tsz\u00f6r ker\u00fclte meg a Napot, a Rosetta \u0171rszonda v\u00e9gre meg\u00e9rkezett c\u00e9lj\u00e1hoz: a 67P\/Cs\u00fcrj\u00fcmov\u2013Gerasimenko \u00fcst\u00f6k\u00f6shez!<\/p>\n<\/div>\n

A Rosetta jelenleg 100 km-es magass\u00e1gban kering a \u00fcst\u00f6k\u00f6s felsz\u00edne felett, \u00e9s r\u00e9szletes adatokat k\u00fcld vissza a F\u00f6ldre \u00faj bar\u00e1tj\u00e1r\u00f3l. Az elk\u00f6vetkez\u0151 n\u00e9h\u00e1ny h\u00e9tben a Rosetta f\u0151 feladata az, hogy megtal\u00e1lja a t\u00f6k\u00e9letes lesz\u00e1ll\u00f3helyet a fed\u00e9lzet\u00e9n l\u00e9v\u0151, Philae (kiejt\u00e9se: FEE-lay) nev\u0171 szond\u00e1nak.<\/p>\n

Ha minden j\u00f3l alakul, alig n\u00e9h\u00e1ny h\u00f3nap m\u00falva a Philae lesz az els\u0151 szonda, amelyet valaha is egy \u00fcst\u00f6k\u00f6s felsz\u00edn\u00e9re engedtek le!<\/p>\n

De a Rosetta \u00fatja ezzel m\u00e9g nem \u00e9r v\u00e9get: a kis \u0171reszk\u00f6z m\u00e9g h\u00f3napokig a \u00fcst\u00f6k\u00f6s mellett fog haladni, mik\u00f6zben az a Nap k\u00f6r\u00fcl kering, majd ism\u00e9t a Jupiter fel\u00e9 veszi az ir\u00e1nyt.<\/p>\n

Egy \u00e9v m\u00falva a kett\u0151s a Naprendszer k\u00f6r\u00fcli \u00fatja sor\u00e1n el\u00e9ri a Naphoz legk\u00f6zelebb es\u0151 pontot \u2013 ekkor fog a \u00fcst\u00f6k\u00f6s igaz\u00e1n ragyogni.<\/p>\n

A \u00fcst\u00f6k\u00f6s\u00f6k kozmikus j\u00e9gb\u0151l \u00e9s k\u0151zetb\u0151l \u00e1ll\u00f3 csom\u00f3k, ami azt jelenti, hogy ahogy a 67P \u00fcst\u00f6k\u00f6s egyre k\u00f6zelebb ker\u00fcl a Naphoz, elkezdi megolvadni. Az \u00fcst\u00f6k\u00f6sb\u0151l elp\u00e1rolg\u00f3 j\u00e9g egy csod\u00e1latos cs\u00f3v\u00e1t hoz l\u00e9tre, olyan cs\u00f3v\u00e1t, amilyet n\u00e9ha szerencs\u00e9nk van l\u00e1tni, ahogy \u00e1thalad az \u00e9gen.<\/p>\n

Sajnos a 67P \u00fcst\u00f6k\u00f6s \u2013 m\u00e9g ragyog\u00f3 cs\u00f3v\u00e1ja ellen\u00e9re sem \u2013 nem lesz l\u00e1that\u00f3 az \u00e9jszakai \u00e9gbolton er\u0151s t\u00e1vcs\u00f6vek n\u00e9lk\u00fcl. Ehelyett a Rosetta valami jobbat k\u00edn\u00e1l nek\u00fcnk: k\u00f6zelr\u0151l megfigyelhetj\u00fck, hogyan v\u00e1ltozik az \u00fcst\u00f6k\u00f6s a Nap vak\u00edt\u00f3 f\u00e9ny\u00e9ben!<\/p>\n

\u00c9rdekes t\u00e9ny<\/h2>\n

A misszi\u00f3 nev\u00e9t a Rosetta-k\u0151r\u0151l kapta, egy \u0151si k\u0151t\u00e1bl\u00e1r\u00f3l, amely lehet\u0151v\u00e9 tette az \u00f3kori egyiptomi hieroglif\u00e1k megfejt\u00e9s\u00e9t.
