Acil durumda haz\u0131r bir savunma arac\u0131 bulunmuyor<\/b><\/p>\n

2022\u2019de ger\u00e7ekle\u015ftirilen Double Asteroid Redirection Test (DART) <\/strong>g\u00f6revi, bir asteroitin y\u00f6r\u00fcngesinin kinetik \u00e7arpma y\u00f6ntemiyle de\u011fi\u015ftirilebilece\u011fini kan\u0131tlad\u0131.
