The Apollo moon missions were a series of spaceflights conducted by NASA between 1961 and 1972, aimed at landing humans on the Moon and bringing them safely back to Earth. The most famous mission, Apollo 11, successfully landed astronauts Neil Armstrong and Buzz Aldrin on the lunar surface in July 1969, making them the first humans to walk on the Moon. In total, there were six successful lunar landing missions, with Apollo 12, Apollo 14, Apollo 15, Apollo 16, and Apollo 17 following Apollo 11. These missions provided valuable scientific data, including lunar samples, and advanced our understanding of the Moon's geology and environment.
