【分析】本题是围绕“太空探索”话题的英语语法填空题，需结合时态、语态、固定搭配等知识点，根据句子主语的动作执行者/承受者、语境的时间提示（如“已”）、固定短语用法，逐空分析判断正确形式。
【解析】1. 句子主语Humans是动作“发射”的执行者，结合语境“已”用现在完成时，结构为have+过去分词，send的过去分词是sent，故填have sent；2. 主语Space probes是动作“送”的承受者，结合“已”用现在完成时的被动语态，结构为have been+过去分词，后接不定式表目的to，故填have been sent to；3. 主语My dream后用be to do结构表“计划、打算”，“成为宇航员”是be an astronaut，主语单数be动词用is，故填is to be an astronaut；4. 固定搭配hope to do sth，“工作”对应work，故填to work；5. 固定搭配inspire sb to do sth，故填inspire to；6. 结合话题“太空探索”，对应短语space exploration，故填space exploration；7. 固定搭配be full of，主语The universe单数be动词用is，故填is full of。
【答案】1. have sent 2. have been sent to 3. is to be an astronaut 4. to work 5. inspire to 6. space exploration 7. is full of
