Crater Launch Site
The Crater Launch Site was introduced in 1.12. It is located on the east side of the rebound peak in the Kerbin Crater. The coordinates of the crater Launch Site are Lat: 8.385973 Long: -179.697715
Like other 1.12 launch sites, it consists of a pad and limited support buildings. The steep slope shows up in the outbuilding arrangement, and that the launch pad's ramp runs into the hillside and is unavailable.
Unsurprisingly, the Crater Rim tracking station is the nearest part of the communications network (if available)
