The Apollo 11 mission was primarily a feat of engineering and piloting, not scientific research. While there were scientists involved in the program, there weren't "main scientists" on the Apollo 11 crew itself.

Here's a breakdown:

* The Crew: The astronauts who landed on the moon were Neil Armstrong, Buzz Aldrin, and Michael Collins. They were trained as pilots and astronauts, not scientists.

* Mission Control: There were scientists working at Mission Control in Houston, monitoring the mission and analyzing data. These scientists were experts in fields like geology, astronomy, and engineering.

* Supporting Scientists: Numerous scientists were involved in the broader Apollo program, designing the experiments, analyzing the samples, and developing the technology for the mission.

So, to answer your question directly: The Apollo 11 mission did not have "main scientists" in the sense of having scientists as part of the crew. The astronauts were the primary figures, but their success relied on the work of many scientists and engineers across various fields.
