The Space Shuttle program marked a major advancement in human space exploration, and a series of space vehicles were produced within the scope of NASA's Space Shuttle Program. One of these vehicles was the Space Shuttle Endeavour. First launched in 1991, Endeavour contributed to space research and was used in various scientific missions.

History of the Endeavour Space Shuttle

Endeavour (OV-105) was produced due to the need for a new space shuttle following the Challenger disaster in 1986. Production began in 1987, and the shuttle was completed in 1991, making its first flight on May 7, 1992. Named after the HMS Endeavour ship used by the famous 18th-century explorer James Cook, Endeavour was the fifth and final shuttle to serve in NASA's Space Shuttle Program.

Technical Specifications and Structural Design

Endeavour was developed based on experiences gained from the Columbia and Challenger shuttles and features a lighter and more efficient design. Its technical specifications can be summarized as follows:

• Length: 37.2 meters
• Wingspan: 23.8 meters
• Height: 17.3 meters
• Launch Weight: 109,000 kg
• Maximum Orbital Speed: 28,000 km/h
• Maximum Crew Capacity: 7 people

Scientific Missions and Contributions

Endeavour played critical roles in scientific research and international cooperation. It contributed to the following missions in particular:

• Hubble Space Telescope Servicing Mission: During the STS-61 mission, Endeavour carried essential equipment for the repair of the Hubble Space Telescope and hosted the astronauts performing the work.
• International Space Station Missions: It played a significant role in the construction and maintenance of the ISS, transporting modules and equipment.
• Education and Experiments in Space: Enabled biological, physical, and engineering experiments in a microgravity environment.

Final Flight and Retirement

Endeavour completed its final flight on November 26, 2011, and was retired following the end of NASA's Space Shuttle Program. Today, it is exhibited at the California Science Center in Los Angeles, California, where it continues to serve the mission of promoting public awareness of the history and importance of space exploration.
