What did Yuri gagarin do in space?

Yuri Gagarin's first mission was also his last. He was launched, made almost but not quite

one single earth orbit, landed 1 hour and 48 minutes after launch, and never flew again.

His duties during that time consisted of looking out the window, describing what he saw

and how he felt, and uttering various other phrases, exclamations, and sound bites for

the benefit of the politicians and reporters with whom he was in radio contact. He had

no control over the flight, and performed no scientific experiments.
