What did Neil Armstrong do after he came back from the moon?

Answer 1

The first thing they did was go into a 3 week quarantine, which started the day they left the moon. During that time, the crew was debriefed extensively on their mission by NASA scientists and those who designed the experiments the astronauts left on the moon. After their quarantine ended, the crew was honored in parades in New York City, Chicago, and Los Angeles along with numerous speaches. Following the parades, the crew departed on a world tour in which they presented flags and pieces of moon rocks to various world leaders.

Armstrong retired from NASA the following year and accepted a position as a professor of aerospace engineering at the University of Cincinnati. He also sat on numerous boards and did a few commercials for Chrysler cars. He was also a part of the commission that investigated the Challenger explosion.
