On July 16, 1969, astronaut Armstrong flew to the moon on the "Apollo-11" spacecraft. On July 20, Armstrong controlled the "Eagle" lunar module to land on the lunar surface. At about 10 p.m. U.S. time that day, he stepped out of the lunar module and set foot on the moon. Armstrong took the lead in setting foot on the desolate and silent land of the moon, becoming the first person to land on the moon and walk on the moon. At that time, he said a famous saying that has been often quoted on countless occasions since then: This is a small step for a man, but a giant step for mankind.
