STS-122 was a NASA Space Shuttle mission to the International Space Station (ISS), flown by the Space Shuttle Atlantis. STS-122 marked the 24th shuttle mission to the ISS, and the 121st space shuttle flight overall. The mission was also referred to as ISS-1E by the ISS program. The primary objective of STS-122 was to deliver the European Columbus science laboratory, built by the European Space Agency (ESA), to the station. It also returned Expedition 16 Flight Engineer Daniel M. Tani to Earth. Tani was replaced on Expedition 16 by LÃ©opold Eyharts, a French Flight Engineer representing ESA. After Atlantis' landing, the orbiter was prepared for STS-125, the final servicing mission for the Hubble Space Telescope.Low Earth Orbit
STS-129 (ISS assembly flight ULF3) was a NASA Space Shuttle mission to the International Space Station (ISS) flown by Atlantis. STS-129 focused on staging spare components outside the station. The 11-day flight included three spacewalks. The payload bay carried two large ExPRESS Logistics Carriers holding two spare gyroscopes, two nitrogen tank assemblies, two pump modules, an ammonia tank assembly, a spare latching end effector for the station's robotic arm, a spare trailing umbilical system for the Mobile Transporter, and a high-pressure gas tank. STS-129 was the first flight of an ExPRESS Logistics Carrier.Low Earth Orbit
The National Aeronautics and Space Administration is an independent agency of the executive branch of the United States federal government responsible for the civilian space program, as well as aeronautics and aerospace research. NASA have many launch facilities but most are inactive. The most commonly used pad will be LC-39B at Kennedy Space Center in Florida.
