NASA’n\u0131n Parker G\u00fcne\u015f Sondas\u0131 (Parker Solar Probe ) bilim tarihinde \u00e7ok \u00f6nemli bir olay\u0131 ger\u00e7ekle\u015ftirerek, G\u00fcne\u015f\u2019in en d\u0131\u015ftaki asmosferi olan korona (ta\u00e7k\u00fcre) tabakas\u0131na girdi ve buradan \u00f6rnekler toplad\u0131. Yani bir ba\u015fka deyi\u015fle bir y\u0131ld\u0131za dokunan ilk uzay arac\u0131 oldu. <\/strong><\/strong><\/p>\n\n\n\n

1,4 milyar dolara mal olan Parker, D\u00fcnya\u2019ya yakla\u015f\u0131k olarak 150 milyon kilometre uzakl\u0131ktaki G\u00fcne\u015f\u2019e, 6,4 milyon kilometre yakla\u015farak bize hayat veren y\u0131ld\u0131z\u0131m\u0131z\u0131n atmosferi ve G\u00fcne\u015f r\u00fczgar\u0131 konusunda veriler toplamaya ba\u015flad\u0131.<\/p>\n\n\n\n

 
Bir otomobil b\u00fcy\u00fckl\u00fc\u011f\u00fcndeki Parker, G\u00fcne\u015f\u2019e yakla\u015ft\u0131\u011f\u0131nda, G\u00fcne\u015f\u2019in \u00e7ok b\u00fcy\u00fck k\u00fctle\u00e7ekim etkisiyle,  uzayda insan taraf\u0131ndan yap\u0131lm\u0131\u015f en h\u0131zl\u0131 cisim olacak ve saniyede 200 km h\u0131za ula\u015facak. Yani bu uzay arac\u0131, \u0130stanbul – Ankara aras\u0131n\u0131 yakla\u015f\u0131k 2 saniyede alabilecek h\u0131za sahip olacak.<\/p>\n\n\n\n

Sondan\u0131n elde edece\u011fi sonu\u00e7lar G\u00fcne\u015f\u2019in nas\u0131l olu\u015ftu\u011fu konusunda da \u00f6nemli bilgiler verecek. Parker uzay arac\u0131n\u0131n, \u00f6zellikle korona tabakas\u0131 konusunda yeni bilgiler vermesi ve G\u00fcne\u015f r\u00fczgar\u0131n\u0131n   k\u00f6keni  konusunda \u00f6nemli ke\u015fifler yapmas\u0131 bekleniyor. Bunun yan\u0131nda G\u00fcne\u015f ile D\u00fcnyam\u0131z aras\u0131nda kalan ve \u201cUzay Havas\u0131\u201d olarak tan\u0131mlanan b\u00f6lge i\u00e7in de \u00e7ok \u00f6nemli verilere ula\u015f\u0131laca\u011f\u0131 d\u00fc\u015f\u00fcn\u00fcl\u00fcyor. Bu bilgiler D\u00fcnya\u2019daki ya\u015fam\u0131, uzay ve uydu teknolojisini olumsuz etkileyen ko\u015fullar\u0131 tahmin etmemizi de sa\u011flayacakt\u0131r.<\/p>\n\n\n\n

G\u00fcne\u015f\u2019e en yak\u0131n olaca\u011f\u0131 6 milyon km uzakl\u0131kta uzay arac\u0131n\u0131n d\u0131\u015f y\u00fczeyinin s\u0131cakl\u0131\u011f\u0131 1380o  <\/sup>C kadar olaca\u011f\u0131ndan, ara\u00e7 \u00e7ok kal\u0131n bir karbon kompozit kalkan ile korunmakta.<\/p>\n\n\n\n

Parker G\u00fcne\u015f Sondas\u0131 12 A\u011fustos 2018 tarihinde Cape Canaveral Uzay \u00dcss\u00fcnden f\u0131rlat\u0131ld\u0131. F\u0131rlat\u0131ld\u0131ktan 3 y\u0131l sonra da G\u00fcne\u015f\u2019e dokundu. Sondan\u0131n 2025 y\u0131l\u0131na kadar hizmet vermesi bekleniyor.<\/em><\/p>\n\n\n\n

Bilindi\u011fi gibi, G\u00fcne\u015f’in kat\u0131 bir y\u00fczeyi yoktur. Ancak \u00e7ok kuvvetli manyetik alan ve k\u00fctle\u00e7ekimi sayesinde, kendisini \u00e7evreleyen \u00e7ok s\u0131cak bir atmosferi bulunuyor. Bu y\u00fcksek s\u0131cakl\u0131k ve bas\u0131nc\u0131n etkisiyle,  y\u00fckl\u00fc par\u00e7ac\u0131klar i\u00e7eren G\u00fcne\u015f f\u0131rt\u0131nas\u0131 dedi\u011fimiz olay ger\u00e7ekle\u015fir. D\u00fcnya\u2019ya ula\u015fan bu y\u00fckl\u00fc par\u00e7ac\u0131klar atmosferimizin manyetosfer tabakas\u0131 taraf\u0131ndan kutuplara y\u00f6nlendirilir. B\u00f6ylece kutup b\u00f6lgelerinde kutup \u0131\u015f\u0131klar\u0131 (Aurora) denen g\u00fczel g\u00f6rsel g\u00f6r\u00fcn\u00fcmler olu\u015fur.<\/p>\n\n\n\n

Parker uzay arac\u0131 \u015fimdiye kadar birka\u00e7 kez koronan\u0131n i\u00e7ine kadar girdi. Sonda G\u00fcne\u015f etraf\u0131nda giderek daha yak\u0131n y\u00f6r\u00fcngede dolanarak G\u00fcne\u015f’e yakla\u015fmaya devam edecek ve sonunda y\u00fczeyden yakla\u015f\u0131k 6 milyon km uzakl\u0131kta olacak.<\/p>\n\n\n\n

Yerden yap\u0131lan G\u00fcne\u015f yar\u0131\u00e7ap\u0131n\u0131n de\u011fi\u015fimi ve G\u00fcne\u015f leke g\u00f6zlemleri, G\u00fcne\u015f\u2019in yar\u0131\u00e7ap\u0131 ile G\u00fcne\u015f aktivitesi aras\u0131nda bir ili\u015fki oldu\u011funu ortaya koymu\u015ftu. G\u00fcne\u015f’in 11 y\u0131ll\u0131k leke \u00e7evrimi incelendi\u011finde, etkin G\u00fcne\u015f durumunda G\u00fcne\u015f\u2019in \u00e7ap\u0131n\u0131n artt\u0131\u011f\u0131 g\u00f6zlenmi\u015ftir. Parker Sondas\u0131n\u0131n bu konuda da yeni bilgiler vermesi beklenmektedir.<\/p>\n\n\n\n

Bu ara\u015ft\u0131rmalar neden \u00f6nemli:<\/strong><\/p>\n\n\n\n

G\u00fcne\u015f bize en yak\u0131n y\u0131ld\u0131zd\u0131r ve yakla\u015f\u0131k olarak 150 milyon km uzakl\u0131ktad\u0131r. Ondan sonra en yak\u0131n y\u0131ld\u0131z olan Proxima Centauri yakla\u015f\u0131k 40 trilyon km uzakl\u0131ktad\u0131r. G\u00fcne\u015f\u2019i inceleyerek, di\u011fer y\u0131ld\u0131zlar\u0131n da olu\u015fumu, ya\u015fam \u00e7izgisi ve \u00f6m\u00fcrleri konusunda bilgi edinebiliriz. Ayn\u0131 zamanda D\u00fcnya\u2019da ya\u015fam\u0131n nas\u0131l ba\u015flad\u0131\u011f\u0131 konusunda da daha mant\u0131kl\u0131 teoriler geli\u015ftirebiliriz.<\/p>\n\n\n\n

G\u00fcne\u015f f\u0131rt\u0131nas\u0131 da incelenmesi gereken \u00e7ok \u00f6nemli bir konu olarak kar\u015f\u0131m\u0131za \u00e7\u0131kmaktad\u0131r. \u00c7\u00fcnk\u00fc saniyede 500 km h\u0131zla D\u00fcnya\u2019ya gelen bu y\u00fckl\u00fc par\u00e7ac\u0131klar, hem D\u00fcnya\u2019daki hem de yak\u0131n uzaydaki hayat\u0131 tehdit etmektedir.<\/p>\n\n\n\n
