Yes, it is true that Apollo 11, the first manned mission of the United States' Apollo space program, successfully landed on the moon on July 20, 1969. The crew of Apollo 11 consisted of three astronauts: Neil Armstrong, Buzz Aldrin, and Michael Collins. Neil Armstrong and Buzz Aldrin descended to the lunar surface in the lunar module named Eagle while Michael Collins orbited the moon in the command module named Columbia. Neil Armstrong became the first person to set foot on the moon, famously saying, "That's one small step for man, one giant leap for mankind." Buzz Aldrin joined him shortly afterward. They conducted experiments, collected samples, and planted the American flag before returning safely to Earth. The Apollo 11 mission is considered a significant milestone in human space exploration.
