A Mars-kutat\u00e1s \u00faj fejezete hamarosan megny\u00edlik. Hossz\u00fa k\u00e9sedelem ut\u00e1n az ESA Mars Express szond\u00e1j\u00e1n tal\u00e1lhat\u00f3 MARSIS radar m\u0171szer hamarosan m\u0171k\u00f6d\u00e9sbe l\u00e9p.<\/p>\n<\/div>\n

A MARSIS az els\u0151 olyan m\u0171szer, amelyet arra terveztek, hogy a Mars narancss\u00e1rg\u00e1s-v\u00f6r\u00f6s felsz\u00edne al\u00e1 l\u00e1sson. M\u0171k\u00f6d\u00e9se sor\u00e1n alacsony frekvenci\u00e1j\u00fa r\u00e1di\u00f3jeleket sug\u00e1roz lefel\u00e9.<\/p>\n

Ezek k\u00f6z\u00fcl sok azonnal visszaver\u0151dik a felsz\u00ednr\u0151l. N\u00e9h\u00e1ny jel azonban \u00e1thatol a talajon, \u00e9s a felsz\u00edn alatti r\u00e9tegekb\u0151l ver\u0151dik vissza.<\/p>\n

Ezeknek a visszhangoknak az elemz\u00e9s\u00e9vel a tud\u00f3sok rem\u00e9lik, hogy felfedeznek f\u00f6ld alatti j\u00e9g- vagy v\u00edztartal\u00e9kokat. Ez az\u00e9rt fontos, mert az \u00e9let \u00e1ltal\u00e1ban a v\u00edz jelenl\u00e9t\u00e9hez k\u00f6t\u0151dik.<\/p>\n

A MARSIS emellett t\u00f6bb kilom\u00e9ter m\u00e9lys\u00e9gig k\u00e9pes felismerni a k\u0151zetr\u00e9tegeket, valamint megm\u00e9rni a hegyek \u00e9s v\u00f6lgyek magass\u00e1g\u00e1t.<\/p>\n

Miel\u0151tt ez megt\u00f6rt\u00e9nhetne, a radar h\u00e1rom r\u00fadszer\u0171 karj\u00e1t ki kell hajtani. Ezeket eredetileg 2004 \u00e1prilis\u00e1ban kellett volna kiengedni, de felmer\u00fclt az aggodalom, hogy beragadhatnak, vagy visszapattanhatnak, \u00e9s k\u00e1ros\u00edthatj\u00e1k az \u0171reszk\u00f6zt.<\/p>\n

\u201cAz ilyen telep\u00edt\u00e9seket a F\u00f6ld\u00f6n nem lehet bemutatni\u201d \u2013 magyar\u00e1zta John Reddy, az ESA munkat\u00e1rsa. \u201cEz\u00e9rt \u2013 hacsak nem lehet \u0151ket az \u0171rben tesztelni \u2013 sz\u00e1m\u00edt\u00f3g\u00e9pes szimul\u00e1ci\u00f3kra kell t\u00e1maszkodnunk.\u201d<\/p>\n

A kock\u00e1zatok alapos elemz\u00e9se ut\u00e1n az ESA \u00fagy d\u00f6nt\u00f6tt, hogy folytatja a k\u00eds\u00e9rletet. El\u0151sz\u00f6r a k\u00e9t 20 m\u00e9ter hossz\u00fa kiny\u00fal\u00e1st helyezik el, majd n\u00e9h\u00e1ny nappal k\u00e9s\u0151bb a 7 m\u00e9teres kiny\u00fal\u00e1st. Ez v\u00e1rhat\u00f3an m\u00e1jus 2. \u00e9s 12. k\u00f6z\u00f6tt fog megt\u00f6rt\u00e9nni.<\/p>\n

A telep\u00edt\u00e9s befejez\u00e9se ut\u00e1n a MARSIS-t h\u00e1rom h\u00e9ten \u00e1t tesztelik. Ezut\u00e1n kezd\u0151dik az izgalmas radaros felder\u00edt\u00e9s.<\/p>","protected":false},"excerpt":{"rendered":"
