From the teaser it seems one of the underlying themes in season 5 will be Freedom.. Freedom on Mars.
For All Mankind is exploring the idea of never ending space race if Soviets would have beaten US in the race for the Moon and the intention of the show is each season to jump about a decade further into the increasingly diverging reality of the show: in season 1, depicting alternate 1969 to 1974, both Soviets and US start building their separate bases near the lunar South pole; in season 2 (1983) both bases have been expanded and the superpowers compete for resources on the Lunar surface; in season 3 (1992 to 1995), Soviets and US are joined by a private company Helios and North Korea for a four way race to be first on Mars; in season 4 (2003) there is a sprawling international human base on Mars and an unexpected side enters the race to get hold on a large, lithium-rich asteroid for mining. Season 5 will start airing on March 27 on Apple TV

Mars cycler is a specialized orbital trajectory designed to shuttle spacecraft between Earth and Mars on a regular, repeating schedule. First proposed by astronaut Buzz Aldrin in the mid-1980s, a cycler orbit intersects both planets’ paths repeatedly, allowing a dedicated transport vehicle - the "cycler" - to swing by Earth, pick up crew or cargo, then cruise through interplanetary space before encountering Mars again. Because the cycler itself never needs to slow down or perform large propulsive maneuvers to match planetary velocities, only small “taxi” vehicles are required to ferry astronauts between the cycler and each planet. This minimizes the delta‑V (fuel) requirements for the main habitat, making long-term habitation modules, radiation shelters, or artificial‑gravity setups more economical and sustainable across multiple missions.
From 2017 onward, SpaceX steadily refined their vision for the 1st human colony on Mars - from the debut of early visuals of an ambitious Mars City during the BFR (Big Falcon Rocket) unveiling, to increasingly detailed illustrations by 2019 showcasing the gleaming stainless‑steel Starship touching down and launching from this base. The 2022 update introduced animations emphasizing mission sequence - transports arriving, crewed modules landing, and a functioning spaceport. By April 2024, the concept had matured into a recognizable, modular Mars habitat design centered around a robust Starship fleet. Finally, in May 2025, the latest rendering unveiled a full-fledged Martian city with partially underground habitats to shield against radiation and Tesla Optimus robots constructing the city, marking the culmination of conceptual evolution from isolated landing pads to a thriving, self‑sustaining urban landscape on Mars.
