11 Ekim 2018’de iki astronotu Uluslararas\u0131 Uzay \u0130stasyonu’na (ISS) ta\u015f\u0131yan bir Rus Soyuz roketi, f\u0131rlatmadan k\u0131sa bir s\u00fcre sonra bir ar\u0131za ya\u015fad\u0131. NASA astronotu Nick Hague ve Rus kozmonot Aleksey Ov\u00e7inin’den olu\u015fan m\u00fcrettebat, g\u00f6revi iptal etmek ve Kazakistan’a acil ini\u015f yapmak zorunda kald\u0131.<\/p>\n\n
F\u0131rlatma, Kazakistan’daki Baykonur Uzay \u00dcss\u00fc’nden TS\u0130 04.40’ta planland\u0131\u011f\u0131 gibi ger\u00e7ekle\u015fti. Ancak u\u00e7u\u015fun \u00fczerinden yaln\u0131zca alt\u0131 dakika ge\u00e7tikten sonra Rusya’n\u0131n uzay ajans\u0131 Roscosmos, itici g\u00fc\u00e7te bir sorun oldu\u011funu bildirdi. F\u0131rlatmadan on bir dakika sonra NASA, m\u00fcrettebat\u0131n balistik ini\u015f modunda D\u00fcnya’ya d\u00f6nd\u00fc\u011f\u00fcn\u00fc duyurdu; bu, uzay arac\u0131n\u0131n herhangi bir iti\u015f g\u00fcc\u00fc olmadan D\u00fcnya’ya d\u00fc\u015fece\u011fi anlam\u0131na geliyordu.<\/p>\n\n
Balistik yeniden giri\u015f prosed\u00fcr\u00fc, uzay arac\u0131n\u0131 h\u0131zla yava\u015flatmak ve astronotlar\u0131 yere geri getirmek i\u00e7in tasarlanm\u0131\u015f, normalden daha dik bir ini\u015f a\u00e7\u0131s\u0131 i\u00e7eriyor. Bu t\u00fcr bir ini\u015f, astronotlar\u0131 ola\u011fan yer\u00e7ekiminin sekiz kat\u0131na kadar a\u015f\u0131r\u0131 yer\u00e7ekimi kuvvetlerine maruz b\u0131rakabilir.<\/p>\n\n
2008 y\u0131l\u0131nda yakla\u015f\u0131k 8G’de balistik yeniden giri\u015fi sa\u011f salim atlatan Amerikal\u0131 astronot Peggy Whitson, deneyimi bir araban\u0131n devrilmesine benzetti. Y\u00fcz\u00fcn\u00fcn geriye do\u011fru \u00e7ekildi\u011fini, nefes almada g\u00fc\u00e7l\u00fck \u00e7ekti\u011fini ve g\u00f6\u011fs\u00fcn\u00fc geni\u015fletmek yerine diyafram\u0131n\u0131 kullanarak nefes almak zorunda kald\u0131\u011f\u0131n\u0131 belirtti.<\/p>\n\n
Yak\u0131n zamanda ger\u00e7ekle\u015fen Soyuz acil ini\u015fi durumunda, yer\u00e7ekimi kuvvetleri 6,7G’ye ula\u015ft\u0131 ve bu da normal kontroll\u00fc ini\u015f s\u0131ras\u0131nda ya\u015fanan 4G’den \u00f6nemli \u00f6l\u00e7\u00fcde y\u00fcksekti.<\/p>\n\n
Olay\u0131n ard\u0131ndan Roscosmos, ar\u0131zan\u0131n nedenini ara\u015ft\u0131rmak i\u00e7in bir “devlet komisyonu” kurdu. NASA da “kapsaml\u0131 bir ara\u015ft\u0131rma” yap\u0131laca\u011f\u0131n\u0131 duyurdu.<\/p>\n\n
\u0130lk raporlar, ar\u0131zan\u0131n u\u00e7u\u015ftan yakla\u015f\u0131k iki dakika sonra, muhtemelen ikinci a\u015fama ayr\u0131lmas\u0131 s\u0131ras\u0131nda meydana geldi\u011fini \u00f6ne s\u00fcrd\u00fc. Ancak sorunun tam niteli\u011fi hen\u00fcz bilinmiyor.<\/p>\n\n
F\u0131rlatma ar\u0131zas\u0131, ISS’yi Alman astronot Alexander Gerst komutas\u0131nda sadece \u00fc\u00e7 m\u00fcrettebat \u00fcyesiyle b\u0131rakt\u0131. ISS m\u00fcrettebat\u0131n\u0131n ba\u015flang\u0131\u00e7ta 13 Aral\u0131k’ta d\u00f6nmesi planlan\u0131yordu, ancak gerekirse y\u00f6r\u00fcngede daha uzun s\u00fcre kalma olana\u011f\u0131na sahipler.<\/p>\n\n
Kazayla birlikte, son y\u0131llarda baz\u0131 sorunlar ya\u015fayan Rusya’n\u0131n Soyuz f\u0131rlatma sisteminin devam eden g\u00fcvenilirli\u011fiyle ilgili sorular g\u00fcndeme geldi. Hem NASA hem de Roscosmos, ISS’nin s\u00fcrekli \u00e7al\u0131\u015fmas\u0131n\u0131 sa\u011flamak i\u00e7in sorunu h\u0131zla \u00e7\u00f6zme y\u00f6n\u00fcnde bask\u0131yla kar\u015f\u0131 kar\u015f\u0131ya.<\/p>\n\n
Ar\u0131zaya ve acil ini\u015fin a\u015f\u0131r\u0131 ko\u015fullar\u0131na ra\u011fmen, astronotlar acil ka\u00e7\u0131\u015f prosed\u00fcr\u00fcn\u00fcn etkinli\u011fi sayesinde hayatta kald\u0131lar. Bu olay, uzay u\u00e7u\u015fu operasyonlar\u0131nda g\u00fcvenlik \u00f6nlemlerinin ve acil durum planlar\u0131n\u0131n \u00f6nemini vurgulamaktad\u0131r.<\/p>\n\n
Soyuz roketindeki ar\u0131zan\u0131n soru\u015fturmas\u0131 devam ediyor ve bulgular, ar\u0131zan\u0131n nedenini belirlemek ve gelecekte benzer olaylar\u0131n ya\u015fanmas\u0131n\u0131 \u00f6nlemek i\u00e7in \u00f6nlemler uygulamada \u00e7ok \u00f6nemli olacak. Soru\u015fturman\u0131n sonucu, uzay ara\u015ft\u0131rmalar\u0131n\u0131n gelece\u011fi ve NASA ile Roscosmos aras\u0131ndaki s\u00fcrekli i\u015f birli\u011fi \u00fczerinde de etkili olacakt\u0131r.<\/p>","protected":false},"excerpt":{"rendered":"
