Who was the first person of African descent to go into space?

Arnaldo Tamayo Méndez (born January 29, 1942) is a Cuban military officer, legislator, and former cosmonaut and the first person of African heritage in space. In 1980, as a member of the crew of Soyuz 38, he became the first Cuban citizen, the first Latin American, the first person of African descent, and the first person from a country in the Western Hemisphere other than the United States to travel into Earth's orbit.

Tamayo was selected as part of the Soviet Union's seventh Intercosmos program on March 1, 1978. His backup in the Intercosmos program was fellow Cuban José López Falcón. Tamayo would spend the next two and a half years in training for the mission.

Tamayo, along with Soviet cosmonaut Yuri Romanenko, was launched into space aboard Soyuz 38 from Baikonur Cosmodrome on September 18, 1980, at 19:11 UTC. After docking with Salyut 6, Tamayo and Romanenko conducted experiments in an attempt to find what caused space adaptation syndrome (SAS), and perhaps even find a cure, and on the crystallisation of sucrose in microgravity, for the benefit of Cuba's sugar industry.

Upon his return to Earth he was decorated with the Hero of the Republic of Cuba medal, the first person to be so honored. In Moscow he received the Order of Lenin and was also named a Hero of the Soviet Union.
