Casa de Cultura Aeroespacial, founded in 2003 and maintained by Brazil’s Air Force, is the public aerospace museum in Alcântara’s historic center and the town gateway to Brazil’s space-launch heritage. Its displays include models, panels, historical documents, launch-related material and a full-scale Sonda IV rocket replica, interpreting the nearby Centro de Lançamento de Alcântara and Brazil’s aerospace programme through guided and educational activities. The federal museum registry lists the museum as open and free; it reports no published accessibility infrastructure, so confirm current exhibits, hours and visitor assistance before travel. This town museum is separate from the operational launch base, whose entry remains restricted. Visitor address: Praça Nossa Senhora do Rosário, s/n, Centro, Alcântara, Maranhão 65250-000, Brazil.
