參考譯文

哈勃望遠(yuǎn)鏡于1990年4月20日由國(guó)家航空航天局放射升空，耗資10多億美元。從最開(kāi)頭哈勃望遠(yuǎn)鏡就有問(wèn)題。它傳送給我們的圖像很令人絕望，由于它的主要鏡子有誤差。國(guó)家航天局預(yù)備訂正這一錯(cuò)誤，為此將把4名宇航員送入太空修復(fù)望遠(yuǎn)鏡?！皧^進(jìn)”號(hào)航天飛機(jī)將把宇航員送上哈勃。當(dāng)宇航員進(jìn)展必要的修復(fù)工作時(shí)，“奮進(jìn)”號(hào)上的一只機(jī)器手將抓住望遠(yuǎn)鏡并托住它。固然，哈勃位于地球的大氣層之外，因此，它很快就會(huì)給我們傳送我們
