The Space Shuttle is a retired, partially reusable low Earth orbital spacecraft system operated from 1981 to 2011 by the U.S. National Aeronautics and Space Administration (NASA) as part of the Space Shuttle program. Its official program name was the Space Transportation System (STS), taken from the 1969 plan led by U.S. vice president Spiro Agnew for a system of reusable spacecraft where it was the only item funded for development. The first (STS-1) of four orbital test flights occurred in 1981, leading to operational flights (STS-5) beginning in 1982. Five complete Space Shuttle orbiter vehicles were built and flown on a total of 135 missions from 1981 to 2011. They launched from the Kennedy Space Center (KSC) in Florida. Operational missions launched numerous satellites, interplanetary probes, and the Hubble Space Telescope (HST), conducted science experiments in orbit, participated in the Shuttle-Mir program with Russia, and participated in the construction and servicing of the International Space Station (ISS). The Space Shuttle fleet's total mission time was 1,323 days. Space Shuttle components include the Orbiter Vehicle (OV) with three clustered Rocketdyne RS-25 main engines, a pair of recoverable solid rocket boosters (SRBs), and the expendable external tank (ET) containing liquid hydrogen and liquid oxygen. The Space Shuttle was launched vertically, like a conventional rocket, with the two SRBs operating in parallel with the orbiter's three RS-25 main engines, which were fueled from the ET. The SRBs were jettisoned before the vehicle reached orbit, while the main engines continued to operate, and the ET was jettisoned after main engine cutoff and just before orbit insertion, which used the orbiter's two Orbital Maneuvering System (OMS) engines. At the conclusion of the mission, the orbiter fired its OMS to deorbit and reenter the atmosphere. The orbiter was protected during reentry by its thermal protection system tiles, and it glided as a spaceplane to a runway landing, usually to the Shuttle Landing Facility at KSC, Florida, or to Rogers Dry Lake in Edwards Air Force Base, California. If the landing occurred at Edwards, the orbiter was flown back to the KSC atop the Shuttle Carrier Aircraft (SCA), a specially modified Boeing 747 designed to carry the shuttle above it. The first orbiter, Enterprise, was built in 1976 and used in Approach and Landing Tests (ALT), but had no orbital capability. Four fully operational orbiters were initially built: Columbia, Challenger, Discovery, and Atlantis. Of these, two were lost in mission accidents: Challenger in 1986 and Columbia in 2003, with a total of 14 astronauts killed. A fifth operational (and sixth in total) orbiter, Endeavour, was built in 1991 to replace Challenger. The three surviving operational vehicles were retired from service following Atlantis's final flight on July 21, 2011. The U.S. relied on the Russian Soyuz spacecraft to transport astronauts to the ISS from the last Shuttle flight until the launch of the Crew Dragon Demo-2 mission in May 2020.

Kefalonia or Cephalonia (Greek: Κεφαλονιά [kefaloˈɲa]), formerly also known as Kefallinia or Kephallenia (Κεφαλληνία), is the largest of the Ionian Islands in western Greece and the sixth-largest island in Greece after Crete, Euboea, Lesbos, Rhodes and Chios. It is also a separate regional unit of the Ionian Islands region. It was a former Latin Catholic diocese Kefalonia–Zakynthos (Cefalonia–Zante) and short-lived titular see as just Kefalonia. The largest cities of Cephalonia are Argostoli and Lixouri.

The USA Basketball Men's National Team, commonly known as Team USA and the United States men's national basketball team, is the basketball team representing the United States. It is the most successful men's team in international competition, winning medals in all twenty Olympic tournaments it has entered, including seventeen golds. In the professional era, the team has won the Olympic gold medal in 1992, 1996, 2000, 2008, 2012, 2016, 2020, and 2024. Three of its gold medal-winning teams have been inducted to the Naismith Memorial Basketball Hall of Fame: the 1960 team, which featured six Hall of Famers (4 players, 2 coaches); the 1992 "Dream Team", featuring 14 Hall of Famers (11 players, 3 coaches), both inducted in August 2010; and the 2008 "Redeem Team", featuring 9 Hall of Famers (6 players, 3 coaches), which was inducted in September 2022. The team is currently ranked first in the FIBA World Rankings. Traditionally composed of amateur players, the US dominated the first decades of international basketball, winning a record seven consecutive Olympic gold medals. However, by the end of the 1980s, American amateurs faced increasing difficulty against seasoned professionals from the Soviet Union and Yugoslavia. In 1989, FIBA modified its rules and allowed USA Basketball to field teams with National Basketball Association players. The first such team, known as the "Dream Team", won the gold medal at the 1992 Summer Olympics in Barcelona, being superior in all matches. With the introduction of NBA players, the team was able to spark a second run of dominance in the 1990s. Facing increased competition, the US failed to win a medal at the 2002 FIBA World Championship, finishing sixth. The 2004 Olympic team, being depleted by a number of withdrawals, lost three games on its way to a bronze medal, a record that represented more losses in a single year than the country's Olympic teams had suffered in all previous Olympiads combined. Determined to put an end to these failures, USA Basketball initiated a long-term project aimed at creating better, more cohesive teams. The US won its first seven games at the 2006 FIBA World Championship in Japan before losing against Greece in the semi-finals; ending the competition with the bronze medal. The team won gold two years later—at the 2008 Summer Olympics—in a dominant fashion. This success was followed up at the 2010 FIBA World Championship, where despite fielding a roster featuring no players from the 2008 Olympic team, the US did not lose a single game en route to defeating host Turkey for the gold medal. The Americans continued this streak of dominance in the 2010s by going undefeated and capturing gold at the 2012 Summer Olympics and 2014 FIBA World Cup. At the 2016 Summer Olympics, the team, led by Mike Krzyzewski for a record third time, won its 15th gold medal, making him the most decorated coach in USA Basketball history. After Krzyzewski stepped down in 2016, Team USA lost to France in the quarter-finals of the 2019 FIBA World Cup, finishing seventh overall. However, Team USA would avenge this loss in the 2020 Summer Olympics, defeating France 87–82 in the final to capture the team's fourth straight gold medal and 16th overall. The team repeated as champions in the 2024 Summer Olympics in Paris, once again defeating France 98–87 in the final.

Concept

The Federal Republic of Germany is a federation and consists of sixteen partly sovereign "states" (German: Länder, sing. Land). Of the 16 states, 13 are so-called "area-states" (Flächenländer); in these, below the level of the state government, there is a division into local authorities (counties and county-level cities) that have their own administration. Two states, Berlin and Hamburg, are city-states, in which there is no separation between state government and local administration. The state of Bremen is a special case: the state consists of the cities of Bremen, for which the state government also serves as the municipal administration, and Bremerhaven, which has its own local administration separate from the state government. It is therefore a mixture of a city-state and an area-state. Three states, Bavaria, Saxony, and Thuringia, use the appellation Freistaat ("free state"); this title is merely stylistic and carries no legal or political significance (similar to the US states that call themselves a commonwealth). The Federal Republic of Germany ("West Germany") was created in 1949 through the unification of the three western zones previously under American, British, and French administration in the aftermath of World War II. Initially, the states of the Federal Republic were Baden (until 1952), Bavaria (Bayern), Bremen, Hamburg, Hesse (Hessen), Lower Saxony (Niedersachsen), North Rhine-Westphalia (Nordrhein-Westfalen), Rhineland-Palatinate (Rheinland-Pfalz), Schleswig-Holstein, Württemberg-Baden (until 1952), and Württemberg-Hohenzollern (until 1952). West Berlin, while still under occupation by the Western Allies, viewed itself as part of the Federal Republic and was largely integrated and considered a de facto state. In 1952, following a referendum, Baden, Württemberg-Baden, and Württemberg-Hohenzollern merged into Baden-Württemberg. In 1957, the Saar Protectorate joined the Federal Republic as the state of Saarland. The next major change occurred with German reunification in 1990, in which the territory of the former German Democratic Republic (East Germany) became part of the Federal Republic, by accession of the re-established eastern states of Brandenburg, Mecklenburg-West Pomerania (Mecklenburg-Vorpommern), Saxony (Sachsen), Saxony-Anhalt (Sachsen-Anhalt), and Thuringia (Thüringen), and the reunification of West and East Berlin into a city state. A referendum in 1996 to merge Berlin with surrounding Brandenburg failed to reach the necessary majority vote in Brandenburg, while a majority of Berliners voted in favour.
