二戰(zhàn)結(jié)束后，航空航天技術(shù)也進(jìn)入了高速發(fā)展期，人類從未停止過探索外太空的步伐。這次新聞的主人公是發(fā)現(xiàn)號(hào)航天飛機(jī)，讓我們一起來聽聽它有什么新的發(fā)現(xiàn)吧！ Hints: space shuttle Discovery 發(fā)現(xiàn)號(hào)航天飛機(jī) sonic boom 聲震 前面的考試說明不用聽寫出來
The space shuttle Discovery made a rare night landing at the Kennedy Space Centre early on Thursday. The night landing, the 11th in the Centre's 94 shuttle missions,endded a 10-day mission to outfit the orbiting International Space Station. Although the spacecraft created a sonic boom that could be heard along much of Florida's eastern seaboard, witness on the ground could not see the orbiter until it was directly over the runway lights. Scattered showers off the Florida coast had threatened to postpone the shuttle's return, but forecasters gave the green light when they decided no rain would fall within 48 kilometres of the space centre.
