Alcântara Space Center

The Alcântara Space Center (Centro Espacial de Alcântara, CEA), former known as Alcântara Launch Center (Centro de Lançamento de Alcântara, ) is a space center and launching facility of the Brazilian Space Agency in the city of Alcântara, located on Brazil's northern Atlantic coast, in the state of Maranhão. It is operated by the Brazilian Air Force (Comando da Aeronáutica). The CEA is the closest launching base to the equator. This gives the launch site a significant advantage in launching geosynchronous satellites, an attribute shared by the Guiana Space Centre.

Construction of the base began in 1982. The first launch occurred on February 21, 1990, when the sounding rocket Sonda 2 XV-53 was launched. On August 22, 2003, the explosion of the third VLS-1 (XV-03) killed 21 people.

The facility is in a strong position for launching satellites into geosynchronous orbits, according to British astrophysicist, Jonathan McDowell. As such, there are plans to launch several international rockets from Alcântara. In 2003 contracts were signed to launch Ukrainian Tsyklon-4 and Israeli Shavit rockets, thought these may have later been launched from their home countries in Ukraine and Israel. In addition there are further plans to launch the Russian Proton rocket.

In the beginning of 2018, Brazilian government offered the possibility to use the spaceport to several U.S. companies. The company Virgin Orbit, was selected to fly their LauncherOne rocket from Alcântara in the first half of 2023.

Construction
Construction of the Alcântara Space Center began in 1982, as the Brazilian Space Agency's existing rocket range at Barreira do Inferno Launch Center was being overtaxed by growing demand for launch capacity. In 2020, the government of Brazil announced their plan to expand the base by more than 12,000 hectares.

Controversies
The construction of the space center was controversial, as the site for the center was located on several quilombos, settlements inhabited largely by descendants of escaped slaves in Brazil. In 1980, Brazil's military government forcibly relocated more than 300 families to inland villages away from the coast to make way for the center. This heavily disrupted their traditional livelihood of fishing and led to multiple cases of malnutrition among the residents.

Human rights concerns over the displacement of locals were reported on during the center's planned expansions in 2001 and 2021, with residents and activists lobbying the government to halt expansions to prevent more communities from being displaced. In 2023, the Brazilian government issued a public apology to the quilombolas and offered reparations. 

Public-private partnership
Companies based in Alcântara as of 2021, with the objective of orbital and sub-orbital launches, for commercial purposes or in partnership with the Brazilian government:


 * 🇨🇦C6 Launch
 * 🇺🇸 Hyperion Rocket Systems
 * 🇺🇸 OrionAST
 * 🇺🇸 Virgin Orbit
 * 🇰🇷 Innospace

As of August 2021, the Brazilian government established Ordinance No. 698, a regulation that follows the FAA 14 CFR part 450 standard, which deals with launch and re-entry licenses in order to follow the world standard in space activities.

Agreement between Brazil and the U.S.
In 2019, Brazil and the U.S. signed an agreement, with the objective of preventing unauthorized access or transfer of U.S. technologies related to the launches from Alcântara.
