Inland Kerbal Space Center
From Kerbal Space Program Wiki
On Kerbin, there are two space centers. The first one is, obviously, the one you control and shoot rockets/planes from. But, there's a second, unfunctional one elsewhere on Kerbin! This second space center is located in an H-shaped valley, North-West of the Main Space Center. The best way to reach the second center is to fly there by plane,
