ما زال الإنسان عاجزاً رغم التقدم الهائل الذي حظي به، عاجزاً عن سبر أغوار المحيطات والعوالم البعيدة عنه في الفضاء الممتد الواسع. فبعد أن تمكن الإنسان من الهبوط على سطح القمر واكتشاف ما فيه، أخذ يتطلع إلى اكتشاف ما حول القمر وما وراءه من كواكب. ومها قيل عن محدودية هذه المحاولات. إلا أن الواقع ينبئنا أن إحدى النتائج الهامة لإطلاق الصواريخ والمركبات الفضائية، هي زيادة معرفتنا بعالمنا زيادة كبيرة.
في هذا الكتاب يقدم أحد مؤلفي الكتب العلمية في هذا العصر دراسة وافية شاملة عن بعض ما اكتشفه الإنسان عن الأرض وكذلك عن القمر. كما يتحدث عن تركيب الأرض وما يحيط بها من أغلفة غازية، والكواكب الأقرب إلى الأرض والجاذبية وأبعاد الفضاء. والكتاب مزود بملحق يحتوي معلومات عن الأرض وآخر يحوي معلومات عن القمر، إضافة إلى جدول بالتواريخ لأهم المكتشفات العلمية المتعلقة بالموضوع.
