F\u0131rlat\u0131lmas\u0131ndan yakla\u015f\u0131k bir hafta sonra, mikrodalga f\u0131r\u0131n boyutundaki uydu, D\u00fcnya y\u00fczeyinin yakla\u015f\u0131k 966 kilometre \u00fczerinde yer alan G\u00fcne\u015f’e senkronize y\u00f6r\u00fcngesinden yer kontrol\u00fc ile ileti\u015fime ge\u00e7ti. \u0130lk a\u015famalarda her \u015fey yolunda giderken, NASA yelkeni a\u00e7ma operasyonlar\u0131na ba\u015flad\u0131\u011f\u0131nda sorunlar ya\u015fanmaya ba\u015flad\u0131.<\/p>\n

<\/span> G\u00fcne\u015f yelkenleri, G\u00fcne\u015f’ten gelen fotonlar sayesinde<\/strong> hareket eder; \u0131\u015f\u0131k taraf\u0131ndan \u00fcretilen enerjiyi kullanarak uzay arac\u0131n\u0131 ileriye do\u011fru iter.

E\u011fer ba\u015far\u0131yla a\u00e7\u0131labilirse, g\u00fcne\u015f yelkeni her bir kenar\u0131 9 metre<\/strong> olacak \u015fekilde geni\u015fleyecek. Yelken, yeterli itme kuvveti \u00fcretmek i\u00e7in yeterince b\u00fcy\u00fck olmal\u0131 ve atmosferik s\u00fcr\u00fcklenmeyi a\u015farak y\u00fckseklik kazanabilmek i\u00e7in yeterince y\u00fcksek bir y\u00f6r\u00fcngede bulunmal\u0131. NASA’ya g\u00f6re, G\u00fcne\u015f \u0131\u015f\u0131\u011f\u0131n\u0131n yelken \u00fczerindeki kuvveti, avucunuzda duran bir ata\u015f\u0131n a\u011f\u0131rl\u0131\u011f\u0131na e\u015fde\u011fer<\/strong>.

Bu arada e\u011fer yelkenler a\u00e7\u0131labilirse g\u00f6revin ilk u\u00e7u\u015f a\u015famas\u0131 yakla\u015f\u0131k iki ay s\u00fcrecek ve sadece g\u00fcne\u015f \u0131\u015f\u0131\u011f\u0131n\u0131n yelken \u00fczerindeki bask\u0131s\u0131 kullan\u0131larak y\u00f6r\u00fcngenin y\u00fckseltilmesi ve al\u00e7alt\u0131lmas\u0131 gibi bir dizi y\u00f6nlendirme manevras\u0131n\u0131 i\u00e7erecek.
