ESA komeedijahtija Rosetta suundub pimekohtingule asteroidi Lutetia juurde. Nagu paljudel esimestel kohtingutel, kohtub Rosetta Lutetia\u2019ga laup\u00e4eva \u00f5htul. Siiski ei tea veel keegi, kuidas Lutetia l\u00e4hedalt v\u00e4lja n\u00e4eb. On t\u00f5en\u00e4oline, et Lutetia pind on v\u00e4ga iidne ja kraatritega kaetud, kuna asteroidid on planeetide tekkimisel j\u00e4rele j\u00e4\u00e4nud kivikillud.<\/p>\n<\/div>\n

Selle salap\u00e4rase peamise asteroidi v\u00f6\u00f6 liikme kohta, mis tiirleb P\u00e4ikese \u00fcmber Marsi ja Jupiteri vahel, on teada v\u00e4he. Siiski on Lutetia kindlasti suurim asteroid, mida kosmoselaev on seni k\u00fclastanud. Esialgu arvatati, et selle l\u00e4bim\u00f5\u00f5t on umbes 95 km, kuid see on vaid veidi elliptiline (munakujuline). Hiljutisemad hinnangud viitavad sellele, et see v\u00f5ib olla palju piklikum ja kuni 134 km lai. Selle heleduse pidevad muutused n\u00e4itavad selgelt, et Lutetia p\u00f6\u00f6rleb ja selle pind on ebatasane.<\/p>\n

Teine m\u00f5istatus puudutab asteroidi koostist. Enamik m\u00f5\u00f5tmisi viitab sellele, et tegemist on \u2018C-t\u00fc\u00fcpi\u2019 asteroidiga, mis sisaldab s\u00fcsiniku\u00fchendeid. M\u00f5ned uuringud viitavad aga sellele, et tegemist v\u00f5ib olla metallirikka \u2018M-t\u00fc\u00fcpi\u2019 asteroidiga.<\/p>\n

Vastused k\u00f5igile neile k\u00fcsimustele saame siis, kui Rosetta 10. juulil l\u00e4heneb kosmosekivile 3 200 km kaugusele. Maapealsed juhtijad t\u00e4psustavad hoolikalt kosmoselaeva trajektoori, et see suudaks saata tagasi umbes kaks tundi \u00fcksikasjalikke pilte. Kosmoselaev hakkab andmeid kohe Maale edastama ja esimesed pildid avaldatakse sama \u00f5htu hiljem. Seej\u00e4rel suundub Rosetta j\u00e4rgmise kohtumise poole \u2013 seekord komeediga T\u0161urjumov-Gerasimenko \u2013, mille p\u00f5nev kohtumine on oodata 2014. aastal.<\/p>","protected":false},"excerpt":{"rendered":"
