Misyonun liderli\u011fini yapan Arizona \u00dcniversitesinden Dante Lauretta \u00f6rneklere e\u015flik edecek.<\/p>\n
Lauretta, ini\u015f \u00f6ncesinde yapt\u0131\u011f\u0131 a\u00e7\u0131klamada, Houston\u2019da kaps\u00fcl\u00fcn a\u00e7\u0131lmas\u0131n\u0131n i\u00e7indeki miktar konusundaki belirsizlik nedeniyle, “as\u0131l \u00f6nemli an” olaca\u011f\u0131n\u0131 s\u00f6yledi.<\/p>\n
