Space Elevator

"That’s why you’re sent to that planet. You [have] to build this thing, you construct this giant space elevator and you funnel resources into it in a few stages. You can finish [Satisfactory] and get to the end and press the ‘I Win’ button."

- Oscar Jilsén

The space elevator is a large structure related to the game-end objective, "Project Assembly". It must be constructed and then used to send resources into orbit. Upgrades unlock higher tiers of milestones. It has a size of 7 x 7 foundations.

Food court
According to Jace and Sofi, there is supposedly a food court at the top of the space elevator, but they are very likely trolling. No fish is served there.
