Final answer:
The mission that landed Neil Armstrong and Buzz Aldrin on the moon, where they collected moon rocks for study, was called Apollo 11.
Step-by-step explanation:
The name of the mission where Neil Armstrong and Buzz Aldrin became the first scientists to take steps on the moon's surface is Apollo 11. This mission marked a significant achievement in human space exploration and was a part of the United States' Apollo program, which conducted a total of nine manned missions to the moon between 1968 and 1972.
On July 20, 1969, Apollo 11 successfully landed on the lunar surface, and the astronauts collected nearly 400 kilograms of samples for detailed laboratory analysis on Earth. These samples have provided invaluable insights into the moon's history and composition.
