Mallama\u2019ya g\u00f6re Vera C. Rubin G\u00f6zlemevi<\/strong> gibi yer tabanl\u0131 b\u00fcy\u00fck teleskoplar, bu t\u00fcr parlak uydu ge\u00e7i\u015flerinden do\u011frudan etkileniyor.

Mallama ve ekibi daha \u00f6nce SpaceX\u2019in Starlink a\u011f\u0131 ba\u015fta olmak \u00fczere farkl\u0131 uydu tak\u0131mlar\u0131n\u0131 da incelemi\u015fti. \u00d6zellikle AST SpaceMobile taraf\u0131ndan i\u015fletilen BlueBird uydular\u0131, devasa antenleri sayesinde bug\u00fcne kadar gece g\u00f6ky\u00fcz\u00fcndeki en parlak yapay nesneler aras\u0131nda yer al\u0131yor. Mevcut BlueBird antenleri 64 metrekarelik bir alana sahipken yeni nesil uydularda bu alan\u0131n 223 metrekareye kadar \u00e7\u0131kmas\u0131 bekleniyor.<\/p>\n

Amazon\u2019un LEO uydular\u0131, eski ad\u0131yla Project Kuiper olarak bilinen a\u011f\u0131n bir par\u00e7as\u0131. Mallama\u2019ya g\u00f6re bu uydular, BlueBird sistemlerine k\u0131yasla belirgin \u015fekilde daha s\u00f6n\u00fck, Starlink uydular\u0131ndan ise biraz daha d\u00fc\u015f\u00fck parlakl\u0131\u011fa sahip. Ancak burada kritik bir fark bulunuyor. Starlink uydular\u0131 yakla\u015f\u0131k 480 kilometre irtifada dolan\u0131rken Amazon uydular\u0131 630 kilometre y\u00fckseklikte konumlan\u0131yor. Starlink\u2019in avantaj\u0131 ise y\u00f6r\u00fcngesinin b\u00fcy\u00fck b\u00f6l\u00fcm\u00fcnde D\u00fcnya\u2019n\u0131n g\u00f6lgesinde kalmas\u0131, bu da g\u00f6r\u00fcn\u00fcrl\u00fc\u011f\u00fc azalt\u0131yor.<\/p>\n

Olumsuzluklar olsa da ara\u015ft\u0131rmac\u0131lar, Amazon\u2019un soruna \u00f6zen g\u00f6sterdi\u011fini ve baz\u0131 \u00f6nlemler almaya ba\u015flad\u0131\u011f\u0131n\u0131 s\u00f6yl\u00fcyor. \u015eirket, yeni uydular\u0131nda g\u00fcne\u015f yans\u0131malar\u0131n\u0131 uzaya yans\u0131tacak \u00e7\u00f6z\u00fcmler \u00fczerinde \u00e7al\u0131\u015f\u0131yor. 2023\u2019te f\u0131rlat\u0131lan ilk test uydular\u0131ndan bu yana Amazon m\u00fchendislerinin, uydular\u0131n D\u00fcnya\u2019ya yans\u0131tt\u0131\u011f\u0131 \u0131\u015f\u0131k miktar\u0131n\u0131 belirgin bi\u00e7imde azaltt\u0131\u011f\u0131 bildiriliyor.<\/p>\n
