Astronauts in Tin follows adults who cosplay as astronauts to step outside the roles attached to adult life. Cosplay is seen not as escape, but as a space where identity can be tested. Through costume, participants move between daily life and imagination, between who they are and who they might become. Their astronaut suits create distance from ordinary expectations. In that distance, play becomes serious. Identity is not fixed, but performed, adjusted, and reimagined. For these adults, cosplay becomes a quiet act of freedom: a way to make room for imagination, self-definition, and change.

In the chrome suit, the fantasy of becoming an astronaut is never separate from reality. Its surface reflects the world back into the image, making imagination and the outside world meet. This overlap is central: it asks what reality is, how identity is shaped, and how both can seem to blend.
