Uzay yar\u0131\u015f\u0131n\u0131n yeni bedeli: Atmosferdeki g\u00f6r\u00fcnmeyen hasarlar<\/b><\/p>\n

1980\u2019lerde kloroflorokarbon (CFC)<\/strong> kaynakl\u0131 ozon delikleri d\u00fcnya \u00e7ap\u0131nda bir \u00e7evre krizi yaratm\u0131\u015ft\u0131. Bu d\u00f6nemin sonunda imzalanan 1987 Montreal Protokol\u00fc, zararl\u0131 kimyasallar\u0131n \u00fcretimini neredeyse tamamen durdurdu ve atmosferde yava\u015f bir iyile\u015fme s\u00fcreci ba\u015flatt\u0131. Ancak ETH Z\u00fcrih ve Canterbury \u00dcniversitesi\u2019nden yeni ara\u015ft\u0131rmalar, bu iyile\u015fmenin modern uzay \u00e7a\u011f\u0131nda yeniden tehlikeye girebilece\u011fini g\u00f6steriyor.<\/p>\n

ETH Z\u00fcrih\u2019ten atmosfer bilimci Sandro Vattioni\u2019nin ekibi, mevcut etkinin s\u0131n\u0131rl\u0131 kald\u0131\u011f\u0131n\u0131 ancak ozonun, CFC\u2019ler \u00f6ncesine k\u0131yasla h\u00e2l\u00e2 yakla\u015f\u0131k %2 oran\u0131nda daha ince<\/strong> oldu\u011funu tespit etti. Bu veriler, Montreal Protokol\u00fc ile sa\u011flanan ilerlemenin tamamlanmad\u0131\u011f\u0131n\u0131, hatta yeni tehditler alt\u0131nda oldu\u011funu g\u00f6steriyor.<\/p>\n

Roket f\u0131rlatmalar\u0131 s\u0131ras\u0131nda ortaya \u00e7\u0131kan egzoz gazlar\u0131, klor, metal partik\u00fclleri ve karbon isi, stratosferin \u00fcst katmanlar\u0131na ula\u015f\u0131yor. Bu bile\u015fenler yaln\u0131zca \u0131s\u0131y\u0131 hapsetmekle kalm\u0131yor, ayn\u0131 zamanda ozon molek\u00fcllerini par\u00e7alayarak koruyucu tabakan\u0131n dengesini bozuyor. Bilim insanlar\u0131, \u00f6zellikle kat\u0131 yak\u0131tl\u0131 roket motorlar\u0131nda bulunan klorun, ozon kayb\u0131nda belirleyici bir rol oynad\u0131\u011f\u0131n\u0131 vurguluyor.<\/p>\n

Canterbury \u00dcniversitesi\u2019nden Laura Revell liderli\u011findeki bir di\u011fer ara\u015ft\u0131rma ekibi, gelece\u011fe y\u00f6nelik farkl\u0131 senaryolar\u0131 modelledi. Orta d\u00fczeydeki bir b\u00fcy\u00fcme senaryosunda (y\u0131lda yakla\u015f\u0131k 884 f\u0131rlatma), 2030\u2019a kadar ozon tabakas\u0131nda k\u00fcresel \u00f6l\u00e7ekte %0,17 oran\u0131nda incelme \u00f6ng\u00f6r\u00fcl\u00fcyor. Y\u00fcksek b\u00fcy\u00fcme senaryosunda ise (y\u0131lda 2.000\u2019den fazla f\u0131rlatma) bu kayb\u0131n %0,29\u2019a, Antarktika \u00fczerinde ise %4\u2019e ula\u015fabilece\u011fi tahmin ediliyor.<\/p>\n

Bilim insanlar\u0131, sorunun \u00e7\u00f6z\u00fcm\u00fcn\u00fcn ke\u015ffi yava\u015flatmak de\u011fil, daha temiz itici g\u00fc\u00e7 teknolojilerine<\/strong> y\u00f6nelmek oldu\u011funu belirtiyor. Oksijen-hidrojen kar\u0131\u015f\u0131m\u0131yla \u00e7al\u0131\u015fan kriyojenik motorlar, \u00e7evresel etkileri en d\u00fc\u015f\u00fck se\u00e7enekler aras\u0131nda yer alsa da karma\u015f\u0131k yap\u0131lar\u0131 nedeniyle \u015fu anda f\u0131rlatmalar\u0131n yaln\u0131zca k\u00fc\u00e7\u00fck bir k\u0131sm\u0131nda kullan\u0131l\u0131yor.<\/p>\n\n
