Dissolution of the Soviet Union

The Soviet Union was formally dissolved and ceased to exist as a sovereign state and subject of international law on December 26, 1991. It also brought an end to the Soviet Union's federal government and to Soviet leader Mikhail Gorbachev's efforts to reform the Soviet political and economic system in an attempt to stop a period of political and economic stagnation.

  • 1984: Space Shuttle Discovery Space Shuttle Discovery is a retired American Space Shuttle orbiter. The spaceplane was one of the orbiters from NASA's Space Shuttle program and the third of five fully operational orbiters to be built. Its first mission, STS-41-D, flew from August 30 to September 5, 1984. Over 27 years of service it launched and landed 39 times, aggregating more spaceflights than any other spacecraft as of December 2024. The Space Shuttle launch vehicle had three main components: the Space Shuttle orbiter, a single-use central fuel tank, and two reusable solid rocket boosters. Nearly 25,000 heat-resistant tiles cover the orbiter to protect it from high temperatures on re-entry.
  • 1984: STS-41-D STS-41-D was the 12th flight of NASA's Space Shuttle program, and the maiden flight of Space Shuttle Discovery. It was launched from Kennedy Space Center, Florida, on August 30, 1984, and landed at Edwards Air Force Base, California, on September 5, 1984. Three commercial communications satellites were deployed into orbit during the six-day mission, and a number of scientific experiments were conducted, including a prototype extendable solar array that would eventually form the basis of the main solar arrays on the International Space Station (ISS).
  • 1983: STS-8 STS-8 was the eighth NASA Space Shuttle mission and the third flight of the Space Shuttle Challenger. It launched on August 30, 1983, and landed on September 5, 1983, conducting the first night launch and night landing of the Space Shuttle program. It also carried the first African-American astronaut to go into space, Guion Bluford. The mission successfully achieved all of its planned research objectives, but was marred by the subsequent discovery that a solid-fuel rocket booster had almost malfunctioned catastrophically during the launch.
  • 1967: Thurgood Marshall Thoroughgood "Thurgood" Marshall was an American lawyer who served as an associate justice of the Supreme Court of the United States from 1967 until 1991. He was the Supreme Court's first African-American justice. Before his judicial service, he was an attorney who fought for civil rights, leading the NAACP Legal Defense and Educational Fund. Marshall was a prominent figure in the movement to end racial segregation in American public schools. He won 29 of the 32 civil rights cases he argued before the Supreme Court, culminating in the Court's landmark 1954 decision in Brown v. Board of Education, which rejected the separate but equal doctrine and held segregation in public education to be unconstitutional. President Lyndon B. Johnson appointed Marshall to the Supreme Court in 1967. A staunch liberal, he frequently dissented as the Court became increasingly conservative.
  • 1590: Tokugawa Ieyasu Tokugawa Ieyasu was a Japanese samurai, daimyo and the founder and first shogun of the Tokugawa shogunate of Japan, which ruled from 1603 until the Meiji Restoration in 1868. He was the third of the three "Great Unifiers" of Japan, along with his former lord Oda Nobunaga and fellow Oda subordinate Toyotomi Hideyoshi. The son of a minor daimyo, Ieyasu once lived as a hostage under daimyo Imagawa Yoshimoto on behalf of his father. He later succeeded as daimyo after his father's death, serving as ally, vassal, and general of the Oda clan, and building up his strength under Oda Nobunaga.
  • 1909: Burgess Shale The Burgess Shale is a fossil-bearing deposit exposed in the Canadian Rockies of British Columbia, Canada. It is famous for the exceptional preservation of the soft parts of its fossils. At c.505 million years old, it is one of the earliest fossil beds containing soft-part imprints.
