Ekip, Cerberus Fossae b\u00f6lgesinde olu\u015fan 21.5 metrelik yeni bir krateri ayr\u0131nt\u0131l\u0131 olarak inceledi. Bu b\u00f6lge, Mars\u2019\u0131n en etkin sismik alanlar\u0131ndan biri olarak biliniyordu. Lakin yap\u0131lan tahliller, buradaki kimi y\u00fcksek frekansl\u0131 sismik olaylar\u0131n asl\u0131nda i\u00e7sel zelzeleler de\u011fil, g\u00f6kta\u015f\u0131 \u00e7arpmalar\u0131n\u0131n tesiriyle olu\u015ftu\u011funu g\u00f6sterdi.<\/p>\n
