The Space Shuttle Atlantis launched on mission STS-110, a pivotal flight in the assembly of the International Space Station (ISS), carrying the S0 truss, which is a vital structural component of the station. The shuttle lifted off from Kennedy Space Center in Florida, solidifying its role in NASA's ongoing efforts to create a permanently inhabited space station. The mission began on April 8, 2002, and lasted for 11 days, demonstrating the complexity and coordination required for international space collaboration.

The S0 truss, which was delivered during this mission, served as the foundational support for future modules and solar arrays on the ISS. This addition enhanced the station's ability to harness solar power and expanded the living and working space for astronauts. The mission included an array of experiments focusing on various scientific disciplines, underlining the importance of the ISS as a multi-national hub for research in microgravity.

Additionally, STS-110 marked a significant milestone in human spaceflight, as Astronaut Jerry L. Ross became the first individual to participate in seven space missions. This achievement highlighted the capabilities of NASA's astronaut corps and the advancements in technology that allowed for more frequent and longer-duration missions in low Earth orbit. The mission was not just a testament to human ingenuity and perseverance but also a celebration of international cooperation in space exploration.
