Aksakl\u0131klara ra\u011fmen NASA, sorunu \u00e7\u00f6zmek i\u00e7in SCOPE’u kurdu. Ekip verileri analiz etti, \u00e7\u00f6z\u00fcmler \u00fczerinde beyin f\u0131rt\u0131nas\u0131 yapt\u0131 ve ar\u0131zalar\u0131n temel nedenlerini belirlemek i\u00e7in eski para\u015f\u00fct test g\u00f6r\u00fcnt\u00fclerini izledi. \u0130lk LDSD testinin keyfi bir tasar\u0131mdan ve yetersiz konu\u015fland\u0131rma tekniklerinden muzdarip oldu\u011fu sonucuna vard\u0131lar.<\/p>\n\n
