Bu durum, Hubble Uzay Teleskobu <\/strong>gibi kritik g\u00f6zlem ara\u00e7lar\u0131n\u0131n elde etti\u011fi karelerde bozulmalar yarat\u0131yor ve ara\u015ft\u0131rmac\u0131lar\u0131n uzak y\u0131ld\u0131zlar\u0131, gezegenleri veya potansiyel tehlikeli asteroitleri tespit etmesini zorla\u015ft\u0131r\u0131yor. \u00c7al\u0131\u015fmada, uydu izlerinin \u00f6n\u00fcm\u00fczdeki on y\u0131l <\/strong>i\u00e7inde Hubble g\u00f6r\u00fcnt\u00fclerinin yakla\u015f\u0131k y\u00fczde 40\u2019\u0131n\u0131<\/strong>, di\u011fer \u00fc\u00e7 teleskobun <\/strong>ise y\u00fczde 96\u2019s\u0131n\u0131 bozabilece\u011fi<\/strong> hesaplan\u0131yor.<\/p>\n

Ara\u015ft\u0131rma ekibinin d\u00f6rt farkl\u0131 teleskop i\u00e7in yapt\u0131\u011f\u0131 sim\u00fclasyonlar, gelecekteki manzaran\u0131n ne kadar \u00e7arp\u0131c\u0131 olaca\u011f\u0131n\u0131 g\u00f6steriyor. Hubble, dar g\u00f6r\u00fc\u015f alan\u0131 sayesinde ortalama 2,14 uydu izine maruz kalacak olsa da gelecek y\u0131l f\u0131rlat\u0131lmas\u0131 planlanan \u00c7in\u2019in Uzay \u0130stasyonu Teleskobu Xuntian her pozda ortalama 92 uydu g\u00f6rebilir. Buna kar\u015f\u0131l\u0131k James Webb Uzay Teleskobu, D\u00fcnya\u2019dan daha uzak konumland\u0131\u011f\u0131 i\u00e7in bu \u0131\u015f\u0131k kirlili\u011finden b\u00fcy\u00fck \u00f6l\u00e7\u00fcde etkilenmiyor.<\/p>\n

Sorunun b\u00fcy\u00fckl\u00fc\u011f\u00fc, son y\u0131llarda h\u0131zla d\u00fc\u015fen f\u0131rlatma maliyetleri ve Starlink benzeri dev haberle\u015fme uydu tak\u0131mlar\u0131n\u0131n \u00e7o\u011falmas\u0131yla daha g\u00f6r\u00fcn\u00fcr hale geldi. ESA verilerine g\u00f6re, 2019\u2019da 5 bin<\/strong> civar\u0131nda olan aktif uydu say\u0131s\u0131 bug\u00fcn 15.800\u2019\u00fc<\/strong> a\u015fm\u0131\u015f durumda.

Uydu izlerinin olu\u015fturdu\u011fu sorun yaln\u0131zca karelerin i\u00e7ine birka\u00e7 parlak \u00e7izgi eklenmesiyle s\u0131n\u0131rl\u0131 de\u011fil. Bu ara\u00e7lar, G\u00fcne\u015f\u2019ten, Ay\u2019dan veya D\u00fcnya\u2019dan yans\u0131tt\u0131klar\u0131 \u0131\u015f\u0131kla g\u00f6r\u00fcnt\u00fcdeki ince parlakl\u0131k de\u011fi\u015fimlerini maskeleyebiliyor. Bu durum, bir y\u0131ld\u0131z\u0131n \u0131\u015f\u0131\u011f\u0131nda meydana gelen k\u00fc\u00e7\u00fck bir d\u00fc\u015f\u00fc\u015f\u00fc alg\u0131lamay\u0131 (yani potansiyel bir \u00f6tegezegenin varl\u0131\u011f\u0131n\u0131 tespit etmeyi) imkans\u0131z hale getirebilir.<\/p>\n

Bilim insanlar\u0131, sorun daha da b\u00fcy\u00fcmeden \u00e7\u00f6z\u00fcm \u00fcretilmesi gerekti\u011fi konusunda hemfikir. Uydu y\u00fczeylerini daha az yans\u0131tacak \u015fekilde karartma \u00e7abalar\u0131, cihazlar\u0131n \u0131s\u0131nmas\u0131na ve daha fazla k\u0131z\u0131l\u00f6tesi \u0131\u015f\u0131k yaymas\u0131na yol a\u00e7t\u0131\u011f\u0131 i\u00e7in teknik engeller de bulunuyor. Ayr\u0131ca teleskoplar\u0131n uydu trafi\u011finin en az oldu\u011fu zamanlarda g\u00f6r\u00fcnt\u00fc almas\u0131n\u0131 planlamak da, y\u00f6r\u00fcngedeki yo\u011funluk artt\u0131k\u00e7a giderek zorla\u015f\u0131yor. Uzmanlar, \u015firketler ve h\u00fck\u00fcmetlerle daha s\u0131k\u0131 koordinasyon kurularak uydular\u0131n teleskoplar\u0131n g\u00f6r\u00fc\u015f hatlar\u0131n\u0131 engellemeyecek y\u00f6r\u00fcngelere yerle\u015ftirilmesi veya belirli y\u00fcksekliklerin d\u00fczenlenmesi gerekti\u011fini belirtiyor.<\/p>\n\n
