I'm at the California Science Center, where one of the 4 retired Space Shuttles is on display.

  This one is the Endeavour. Its last mission was STS-134, in May 2011:

  2. Space Shuttle Endeavour
    
    Space Shuttle Endeavour (Orbiter Vehicle Designation: OV-105) is a retired orbiter from NASA's Space Shuttle program and the fifth and final operational Shuttle built. It embarked on its first mission, STS-49, in May 1992 and its 25th and final mission, STS-134, in May 2011. STS-134 was expected to be the final mission of the Space Shuttle program, but with the authorization of STS-135, Atlantis became the last shuttle to fly. The United States Congress approved the construction of Endeavour in 1987 to replace the Space Shuttle Challenger, which was destroyed in 1986. NASA chose, on cost grounds, to build much of Endeavour from spare parts rather than refitting the Space Shuttle Enterprise, and used structural spares built during the construction of Discovery and Atlantis in its assembly. History Following the loss of Challenger, in 1986 NASA was authorized to begin the procurement process for a replacement orbiter. Again, a major refit of the prototype orbiter Enterprise was looked at and rejected on cost grounds, with instead...

  The Endeavour was the newest orbiter of the small STS fleet. It flew to space and back 25 times from 1992 to 2011:

  2. List of Space Shuttle missions
    
    The Space Shuttle was a partially reusable low Earth orbital spacecraft system operated by NASA (the National Aeronautics and Space Administration). Its official program name was Space Transportation System (STS), taken from a 1969 plan for a system of reusable spacecraft of which it was the only item funded for development. Operational missions launched numerous satellites, conducted science experiments in orbit, and participated in construction and servicing of the International Space Station (ISS). The first of four orbital test flights occurred in 1981, leading to operational flights beginning in 1982. From 1981 to 2011 a total of 135 missions were flown, all launched from Kennedy Space Center (KSC) in Florida. During that time period the fleet logged 1,322 days, 19 hours, 21 minutes and 23 seconds of flight time. The longest orbital flight of the Shuttle was STS-80 at 17 days 15 hours, while the shortest flight was STS-51-L at one minute 13 seconds when the Space Shuttle Challenger broke apart during launch. The cold morning shrunk the O-Ring on the right Solid Rocket Booster causing the external fuel tank to explode. The shuttles...

  Details of the heat shield tiles and two hatches that connected the orbiter to the external fuel tank, feeding the 3 main engines during ascent.
  After being depleted, the tank would disconnect and burn in the atmosphere.

  The hydrogen engines of the Space Shuttle were among the most efficient ever created, but required extensive refurbishing after every flight.

  The interior of the nozzle contained thousands of tiny channels in which the cryogenic propellent circulates to exchange heat and prevent the metal from melting.
  In the center you can see the holes of the injector that sprays oxygen and hydrogen into the combustion chamber. Essentially, a shower head spitting fire 🔥

  This one was used for a rendezvous with a Soyuz in 1975.
  Even in the middle the cold war, Russians and Americans found peaceful ways to collaborate on space exploration.

  1. Apollo–Soyuz
    
    Apollo–Soyuz was the first crewed international space mission, carried out jointly by the United States and the Soviet Union in July 1975. Millions of people around the world watched on television as a United States Apollo spacecraft docked with a Soviet Union Soyuz capsule. The project, and its memorable handshake in space, was a symbol of détente between the two superpowers during the Cold War, and it is generally considered to mark the end of the Space Race, which had begun in 1957 with the Soviet Union's launch of Sputnik 1.The mission was officially known as the Apollo–Soyuz Test Project (ASTP; Russian: Экспериментальный полёт «Союз» – «Аполлон» (ЭПАС), romanized: Eksperimentalniy polyot Soyuz–Apollon (EPAS), lit. 'Experimental flight Soyuz-Apollo', and commonly referred to in the Soviet Union as Soyuz–Apollo; the Soviets officially designated the mission as Soyuz 19). The unnumbered American vehicle was left over from the canceled Apollo missions, and was the last Apollo module...
