What event does Vincent train for throughout GATTACA?

In "GATTACA," Vincent trains specifically for a space mission to Titan, one of Saturn's moons. His aspiration to go beyond Earth is central to his character and showcases his determination to overcome the genetic discrimination that society imposes on those who are considered "invalids"—people conceived without genetic enhancement. Titan represents not only a goal but also a symbol of hope and the fulfilment of Vincent’s dreams, contrasting with the limitations society tries to impose on him due to his genetic background. This mission drives the plot forward and highlights themes of identity, ambition, and the pursuit of one’s dreams in a society that values genetic perfection over individual merit.
