مع تصاعد الاهتمام من قبل وكالات الفضاء الكبرى في العالم بدراسة كوكب المريخ، وفحص جميع المعلومات المتعلقة به وببيئته، التي تستهدف جميعها في النهاية...

تُظهر نتائج البحث مدى أهمية إدراج الإنسان في التخطيط لأي مهمة بشرية في الفضاء. يمكن لعدد قليل يصل إلى 22 شخصا الحفاظ على مستعمرة من الرواد لفترة كافية، لتأسيس وجود بشري على كوكب المريخ. هذا هو الاستنتاج الذي توصلت إليه دراسة جديدة أجراها فريق من الباحثين في الولايات المتحدة. استخدموا خلالها النمذجة والمحاكاة لتحديد الحد الأدنى لحجم السكان الأولي لمستعمرة ناجحة على المريخ، تستمر في الازدهار. وهذا أقل بكثير من التقدير السابق البالغ 110 أشخاص.
