解析
【分析】
本题是结合时事的英语语法填空题，需通读全文理解大意后，针对每个空格，结合语法规则（时态、词性转换、被动语态等）、固定搭配、上下文逻辑来确定答案。解题思路为：先分析空格处的句子成分、所需词性/形式，再结合提示词或语境推导正确答案。
【解析】
1. 由助动词has可知，此处为现在完成时，结构为“has+过去分词”，提示词show的过去分词是shown，故填shown。
2. 此处表示“第一面飞到月球背面的国旗”，需用序数词，one的序数词是first，故填first。
3. 修饰名词material，结合破折号后“玄武岩”可知是“不寻常的”材料，usual的反义词为unusual，故填unusual。
4. 主语rock与动词find是被动关系，情态动词can后接“be+过去分词”，find的过去分词是found，故填be found。
5. 此处特指前文提到的玄武岩，需用定冠词the，故填the。
6. a number of后接可数名词复数，challenge的复数形式是challenges，故填challenges。
7. 由than可知，此处需用形容词比较级，thin的比较级是thinner，故填thinner。
8. 固定搭配about the size of表示“大约……的尺寸”，符合语境，故填about。
9. 前后句为因果关系，后句说明原因，需用连词because，故填because。
10. 由时间状语for a long time及语境可知，此处表示“将被人们记住”，用一般将来时的被动语态，结构为“will be+过去分词”，remember的过去分词是remembered，故填will be remembered。
【答案】
1. shown 2. first 3. unusual 4. be found 5. the 6. challenges 7. thinner 8. about 9. because 10. will be remembered
