Step 1 : Introduction to the question "Which of these astronauts did NOT walk on the Moon?"
...Although Michael Collins was a key member of the historic Apollo 11 crew, he never set foot on the lunar surface. While Neil Armstrong and Buzz Aldrin became the first humans to walk on the Moon, Collins remained in lunar orbit aboard the Command Module Columbia, performing critical navigation, communication, and spacecraft maintenance tasks. His role was essential to the mission’s success—without his steady command, Armstrong and Aldrin wouldn’t have had a ride home. Despite never walking on the Moon, Collins is celebrated as one of NASA’s most accomplished and respected astronauts.
