Marca 1986 se je vesoljsko plovilo Giotto agencije ESA pribli\u017ealo jedru Halleyjevega kometa na razdaljo 600 km. Poslalo je prve bli\u017enje posnetke ledenega jedra kometa. Sedaj je na poti k kometu \u0161e ena vesoljska sonda ESA, imenovana Rosetta. Rosetta je najbolj zapletena vesoljska misija, ki jo je Evropa kdaj izvedla.<\/p>\n<\/div>\n

3-tonsko vesoljsko plovilo preva\u017ea 11 eksperimentov in sondo za pristanek, na kateri je \u0161e 9 eksperimentov. Energijo \u010drpa iz dveh ogromnih son\u010dnih panelov, vsak dolg 14 metrov.<\/p>\n

Sonda Rosetta, ki je bila izstreljena 2. marca 2004, bo potrebovala 10 let, da dose\u017ee komet \u010curjumov-Gerasimenko. Njena ovinkasta pot vklju\u010duje tri prelete mimo Zemlje in enega mimo Marsa. Rosetta se bo tudi ve\u010dkrat pribli\u017eala glavnemu asteroidnemu pasu med Marsom in Jupitrom ter se od njega oddaljila. To ji bo omogo\u010dilo, da posname bli\u017einske posnetke dveh asteroidov, Steinsa in Lutetije.<\/p>\n

Ob prihodu v bli\u017eino kometa bo sonda Rosetta upo\u010dasnila hitrost in spremenila svojo pot, tako da bo vstopila v orbito le nekaj kilometrov nad trdnim jedrom.<\/p>\n

Ko bo komet kartiran, bo sonda Rosetta izstrelila svoj pristajalnik (imenovan Philae). Ta se bo pritrdil na jedro kometa in poslal prve slike s povr\u0161ine kometa.<\/p>\n

V vi\u0161ini bo sonda sledila kometu, ki se hitro pribli\u017euje notranjemu delu Oson\u010dja. Med tem 18-mese\u010dnim zasledovanjem se bo zamrznjen led na kometu spremenil v plin, pri \u010demer bodo v vesolje \u0161vigali curki snovi. Rosetta nam bo prvi\u010d prikazala dramati\u010dne spremembe, ki se dogajajo, ko Sonce segreva ta vesoljski ledenik.<\/p>","protected":false},"excerpt":{"rendered":"
