Mars colony for 5000 people in "For All Mankind" season 5

In season 5 of the alternate-history sci-fi series For All Mankind, set in an alternate 2012 where tensions between Martian colonists and their former home, Earth, reach boiling point, the international Happy Valley colony on Mars has grown into a settlement of more than five thousand residents. Happy Valley Base, located in Melas Chasma within the Valles Marineris system, was founded by NASA in 1995 during season 3. By season 4 (alternate 2003), it housed around 200 people.

In the nine years since, Happy Valley, governed by the Mars-6 Alliance (US, USSR, ESA, India, Japan, and the Coalition of Communist Countries for Spaceflight), has expanded far beyond simple growth. The colony now supports a genuine multi-generational population and features a far larger and more interconnected complex: expanded power, communications, fuel, and regolith processing facilities, multiple large agrodomes (several already operational with more under construction), a developed spaceport, and the distinctive radiation shield tower system. The central hub includes arrival halls with rover airlocks, control and laboratory modules, warehouses, and living quarters. A noticeable addition is the emergence of civilian commercial and social spaces alongside the industrial backbone. Helios and its Soviet competitor Kuragin both maintain offices on Mars; Kuragin is actively building a space elevator.

For All Mankind runs on the premise of a never-ending space race in a timeline where the Soviets reached the Moon first. Each season leaps roughly a decade into an increasingly divergent reality: season 1 (1969–1974) sees rival lunar South Pole bases; season 2 (1983) escalates resource competition on the Moon; season 3 (1992–1995) brings Helios and North Korea into a four-way race to Mars; season 4 (2003) features Happy Valley workers redirecting the lithium-rich asteroid Goldilocks into Mars orbit after "stealing" it from the M-7 Alliance.

Here we have collected high-resolution screenshots from season 5 (sourced from 4K UHD and optimized for web). They show the colony's exteriors and interiors without major plot reveals. There are separate galleries for Happy Valley agrodomes, spaceport and the Helios' office.
