Commercial space launch sites are facilities that support the processing, integration and launch of vertical or horizontal launch vehicles. Traditional vertical launch vehicles typically take off under rocket power from a fixed launch pad. Additional vertical launch infrastructure such service structures, lightning protection, propellant loading systems, vehicle processing facilities, etc. are often provided to support launch activities. Horizontal reusable launch vehicles are launch systems that can take off and land horizontally on conventional runways. Commercial space launch sites also provide necessary support services for launch operations, including utilities, security and firefighting capabilities.

Both the horizontal and vertical launch sites proposed by MLI will encompass a minimal footprint. Existing structures at each site will be repurposed to the extent possible, and additional structures will be constructed in accordance with existing zoning laws. As currently envisioned, renewable energy, solar and wind technologies will be used to provide electrical power. As MLI is only proposing the launch of small lift class vehicles, the vertical launch site footprint will be significantly smaller than those currently utilized at launch site facilities in Florida or California.
