The payload bay will carry two large ExPRESSLogistics 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. This will be the first flight of an ExPRESS Logistics Carrier. The completion of this mission will leave five space shuttle flights remaining until the end of the program.
