STS-129 (ISS assembly flight ULF3) was a NASA Space Shuttle mission to the International Space Station (ISS). Atlantis was launched on November 16, 2009, at 14:28 EST, and landed at 09:44 EST on November 27, 2009, on runway 33 at the Kennedy Space Center's Shuttle Landing Facility. It was also the last Shuttle mission of the 2000s. 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. The completion of this mission left six Space Shuttle flights remaining until the end of the Space Shuttle program, after STS-135 was approved in February 2011. Crew Crew seat assignments Mission payload ExPRESS Logistics Carriers 1 and 2 The primary payload of STS-129 was the ExPRESS (Expedite the Processing of Experiments to the Space Station) Logistics Carrier (ELC-1) and the ELC-2. Each steel framework has a mass capacity of , with a volume of 30 m³ (total with spares, ELC-1: and ELC-2: ). The Goddard Space Flight Center served as the overall integrator for ELC-1 and ELC-2, with the addition of components manufactured by the Brazilian Space Agency. The spare hardware stored on ELC-1 includes an Ammonia Tank Assembly, a Battery Charger Discharge Unit, a station robotic arm Latching End Effector, a Control Moment Gyroscope, a Nitrogen Tank Assembly, a Pump Module, a Plasma Contactor Unit and two empty Passive Flight Releasable Attachment Mechanisms. ELC-2 was launched with an oxygen-filled High Pressure Gas Tank (HPGT), a Cargo Transport Container (CTC-1), a Mobile Transporter Trailing Umbilical System Reel Assembly (MT TUS-RA), a Control Moment Gyroscope, a Nitrogen Tank Assembly, a Pump Module, MISSE attach hardware and one empty site for future payloads. ELC-1 was installed on the Unpressurized Cargo Carrier Attachment System #2 (UCCAS 2) on the P3 (port side) segment of the main truss. ELC-2 was installed on the Upper Outboard Payload Attach System on the S3 (Starboard Segment 3) of the main truss. Materials on International Space Station Experiment (MISSE) carrier ELC2 also carried MISSE-7, an experiment that will expose a variety of materials and coatings being considered for
