Launch pad
A launch pad is where rockets and spacecraft are placed until they are ready to blast off. NASA has its own launch pads for its spacecraft.[1] Launch pads are often made out of steel reinforced concrete. Launch pads for larger spacecraft will often have towers to support it during its launch.
