Module 5 The Conquest of the UniversePart Two Teaching ResourcesSection 1 Background readings 1. About Apollo 11Seven months after Apollo 8’s flight, on July 16th in 1969, Apollo 11 lifted off for the moon from Cape Kennedy(肯尼迪) and four days later, on Sunday, July 20th, the computer guided the lunar module(登月舱 ) to touchdown(降落). It was afternoon in America, evening in Europe and morning in Japan. As the module moved towards the surface of the moon, Armstrong and Aldrin suddenly realized that the spot they were programmed to land on was a huge hole filled with boulders(巨石). Quickly Armstrong took control and moved the Eagle to a flat area where he made a perfect landing in the Sea of Tranquility( 宁 静 之 海 ). To the watching world he sent the message: Houston, Tranquility Base here. The Eagle has landed. They made ready for the next amazing experience-walking on the moon! They pulled on their nice layered(被分层的) protective suits and depressurized(减压) the crew compartment(分隔间) before Armstrong climbed down the ladder to become the first person to stand on lunar soil. His never-to-be-forgotten words to the world were,“That’s one small step for a man, one giant step for mankind.” The two men spent more than two hours on the moon. They unveiled (揭开)a plague(天灾) on the landing gear( 工具，用具 ), took photographs, set up various scientific experiments, and collected samples of rocks and sand. When they returned to the mother ship, it was repressurized(加压) before they removed their suits and took off to rejoin Collins in the orbiting command module Columbia, which was waiting to carry them and their precious cargo back to Earth.2.
