Rocket Launch Center
The Brazilian Space Agency maintains a launch site in Alcântara.
The Alcântara Launch Center is located in the historic city of Alcântara, close to city of Sao Luis, capital of the State of Maranhão. The geographic coordinates are 2°18′S and 44°22′W.
The Launch Center comprises the Cyclone-4 Launch Site, under the responsibility of ACS, and a set of facilities under the responsibility of the Brazilian Air Force (FAB), and the Brazilian Space Agency (AEB), which include general infrastructure and dedicated complexes for the launching of the Brazilian Satellite Launch Vehicle (SLV).
The overall infrastructure consists of an airport with a 2,600 meter-long runway, a Command and Control Sector equipped with telemetry, communication, meteorology, radar and electricity supply systems, and an Administrative center with hotels, a hospital and administrative buildings.
The general infrastructure also includes roads, and a project for a seaport which is currently underway.
Technical Complex
The main components of the Cyclone-4 launch site are the Technical Complex and the Launch Complex. The Satellite Assembly Integration and Testing Building is located in the Technical Complex. This building has clean rooms for receiving, testing, fuelling and satellite integration to the launch vehicle payload unit. This building is connected to the Launch Vehicle Assembly, Integration and Testing Building, where the launch vehicle parts are received and tested, and the entire vehicle assembled. The integration of the payload unit, already with the satellite, to the launch vehicle is performed in this building.
The Launch Complex receives the Cyclone-4 launch vehicle horizontally by a railway that connects the launch complex to the technical complex. The launch vehicle is tilted to the vertical position, and the final tests are performed automatically. The launch complex is designed so that the launch vehicle fuelling and launching are performed automatically, thus allowing a safe and reliable operation.
On August 22, 2003, an accident occurred when a VLS-1 rocket accidentally exploded, killing 21 Brazilian technicians.
