Apple TV has announced a sixth and final season of "For All Mankind", turning the series into a long-term franchise play with a spinoff. The decision to renew the show is seen as a controlled conclusion rather than a late-stage cancellation. The sixth season will be the last, but there is a companion series called Star City set to release on May 29. The spinoff will explore political control and infrastructure, shifting the story from exploration to governance. The move aligns with the evolution of a Mars colony and the struggle between Earth governments trying to impose authority.
