Tutkijat uskovat, ett\u00e4 Jupiterin kuiden j\u00e4isen pinnan alla saattaa olla valtavia valtameri\u00e4. ESA:n JUICE-luotainlennon tarkoituksena on selvitt\u00e4\u00e4, voisiko niiden valtameriss\u00e4 olla el\u00e4m\u00e4\u00e4 ja voisiko Jupiterin kaltaisten kaasuj\u00e4ttil\u00e4isten ymp\u00e4rill\u00e4 olla elinkelpoisia maailmoja. ESA on valinnut 11 tieteellist\u00e4 kokeilua, joilla tutkitaan j\u00e4ttil\u00e4isplaneettaa ja sen kuita.<\/p>\n<\/div>\n

JUpiter ICy moons Explorer -luotain on tarkoitus laukaista vuonna 2022, ja sen matka aurinkokunnan suurimpaan planeettaan, Jupiteriin, kest\u00e4\u00e4 8 vuotta. Sen j\u00e4lkeen se viett\u00e4\u00e4 v\u00e4hint\u00e4\u00e4n kolme vuotta tarkkailemalla planeettaa ja kolmea sen suurinta j\u00e4\u00e4kuuta: Ganymedesia, Callistoa ja Europaa.<\/p>\n

Jupiterille l\u00e4hetett\u00e4v\u00e4t laitteet sis\u00e4lt\u00e4v\u00e4t kameroita ja spektrometrej\u00e4 (valon mittaamiseen), laseraltimetrin (korkeuden mittaamiseen) sek\u00e4 j\u00e4\u00e4t\u00e4 l\u00e4p\u00e4isev\u00e4n tutkan. Lennolla on mukana my\u00f6s magnetometri (magneettikenttien mittaamiseen). N\u00e4m\u00e4 laitteet kehitet\u00e4\u00e4n 15:n Euroopan maan sek\u00e4 Yhdysvaltojen ja Japanin tutkijaryhmien yhteisty\u00f6n\u00e4.<\/p>\n

Avaruusluotain lent\u00e4\u00e4 yli kaksitoista kertaa Calliston, aurinkokunnan kraatterisimman taivaankappaleen, ohi. Se lent\u00e4\u00e4 my\u00f6s kahdesti Europan ohi, jotta se voi mitata sen j\u00e4\u00e4kuoren paksuuden. JUICE p\u00e4\u00e4tyy kiertoradalle Ganymede-nimisen kuun ymp\u00e4rille, jossa se tutkii sen j\u00e4ist\u00e4 pintaa ja sis\u00e4ist\u00e4 rakennetta, mukaan lukien pinnan alla sijaitsevan meren. Ganymede on aurinkokunnan suurin kuu ja ainoa, jonka tiedet\u00e4\u00e4n tuottavan omaa magneettikentt\u00e4\u00e4.<\/p>\n

\u201cJupiter ja sen j\u00e4iset kuut muodostavat er\u00e4\u00e4nlaisen oman pienimuotoisen aurinkokuntansa, joka tarjoaa eurooppalaisille tutkijoille ja kansainv\u00e4lisille kumppaneillemme mahdollisuuden oppia lis\u00e4\u00e4 muiden t\u00e4htien ymp\u00e4rill\u00e4 olevien, mahdollisesti elinkelpoisten maailmojen muodostumisesta\u201d, sanoo Dmitrij Titov, ESA:n JUICE-tutkimuksen tutkija.<\/p>","protected":false},"excerpt":{"rendered":"
