一:人类首次登月 The human race has always been fascinated by the stars and the vast expanse of space. One of the most significant milestones in space exploration was the first manned landing on the Moon. On July 20, 1969, astronauts Neil Armstrong and Buzz Aldrin stepped onto the lunar surface, while Michael Collins remained in orbit around the Moon in the command module. The Apollo 11 mission was a monumental achievement for humanity. It was not just a technological triumph but also a symbol of human curiosity and determination. The spacecraft used for this mission, the Saturn V rocket, was one of the most powerful rockets ever built.
