Launch Pad & Location
Space Launch Complex 8
Vandenberg SFB, CA, USA
The Space Launch Complex 8 launch pad has hosted 9 rocket launches, including 9 orbital launch attempts. The Vandenberg SFB, CA, USA launch site has been the location for 862 total rocket launches.
Vandenberg Space Force Base is a United States Space Force Base in Santa Barbara County, California. Established in 1941, Vandenberg Space Force Base is a space launch base, launching spacecraft from the Western Range, and also performs missile testing. The United States Space Force's Space Launch Delta 30 serves as the host delta for the base, equivalent to an Air Force air base wing. In addition to its military space launch mission, Vandenberg Space Force Base also hosts space launches for civil and commercial space entities, such as NASA and SpaceX.
Orbital Sciences Corporation Minotaur I Rocket
The Minotaur I launch system is derived from converted Minuteman II ICBMs and is used to launch small satellites for the US Government. The first and second stages, taken directly from decommissioned Minuteman missiles, are mated to the Orion third and fourth stages taken from the Pegasus XL air-launched rocket family. An optional hydrazine-powered fifth stage called HAPS can be used.The Minotaur I launch system is derived from converted Minuteman II ICBMs and is used to launch small satellites for the US Government.
