Ancak bu sadece ba\u015flang\u0131\u00e7. \u00c7\u00fcnk\u00fc nihai projede yer alacak uydular, 54 metre geni\u015fli\u011finde dev aynalara sahip olacak. <\/strong>Bu aynalar, ayn\u0131 Starlink uydular\u0131 gibi al\u00e7ak D\u00fcnya y\u00f6r\u00fcngesinde konumland\u0131r\u0131lacak. Bu kadar b\u00fcy\u00fck ve bu kadar al\u00e7ak bir y\u00f6r\u00fcngede d\u00f6nen y\u00fczlerce ayna, g\u00f6ky\u00fcz\u00fcnde ola\u011fan\u00fcst\u00fc parlak izler b\u0131rakaca\u011f\u0131ndan, bilim insanlar\u0131na g\u00f6re teleskoplardan \u00e7\u0131plak g\u00f6ze kadar her seviyede g\u00f6zlem \u00fczerinde ka\u00e7\u0131n\u0131lmaz bir etki yaratacak. Bilim d\u00fcnyas\u0131n\u0131n bu projeye y\u00f6nelik ele\u015ftirilerin arkas\u0131nda da temelde bu yat\u0131yor.\u00a0Royal Astronomical Society\u2019den Robert Massey<\/strong>, projenin temel amac\u0131n\u0131n geceyi ayd\u0131nlatmak oldu\u011funu hat\u0131rlatarak, \u201cBu astronomi a\u00e7\u0131s\u0131ndan neredeyse felaket tan\u0131m\u0131na girer\u201d a\u00e7\u0131klamas\u0131n\u0131 yapt\u0131.<\/p>\n

Bu da astronomi \u00e7al\u0131\u015fmalar\u0131na a\u011f\u0131r bir darbe vuracak.<\/p>\n

Ele\u015ftiriler sadece astronomiyle s\u0131n\u0131rl\u0131 de\u011fil.

Fakat g\u00f6kbilimciler bu a\u00e7\u0131klamay\u0131 ikna edici bulmuyor. \u00c7\u00fcnk\u00fc ge\u00e7mi\u015fte Starlink gibi \u00e7ok daha s\u00f6n\u00fck uydular i\u00e7in bile yap\u0131lan \u201cka\u00e7\u0131nma\u201d stratejileri pratikte etkili olmad\u0131.<\/p>\n

FCC’ye yap\u0131lan ba\u015fvuruda da buna vurgu yap\u0131l\u0131yor. E\u011fer izin \u00e7\u0131karsa, insanl\u0131k tarihinde ilk kez, g\u00f6ky\u00fcz\u00fc ticari ayd\u0131nlatma i\u00e7in planl\u0131 olarak \u201cyeniden tasarlanm\u0131\u015f\u201d olacak.
