Mission Payloads
STS-122 was the ISS Assembly Flight 1E, which delivered the European Columbus laboratory module to the station, along with the Biolab, Fluid Science Laboratory (FSL), European Drawer Rack (EDR), and European Physiology Modules (EPM) payloads.
STS-122 also carried the Solar Monitoring Observatory (SOLAR), the European Technology Exposure Facility (EuTEF), and a new Nitrogen Tank Assembly, mounted in the cargo bay of an ICC-Lite payload rack, as well as a spare Drive Lock Assembly (DLA) sent to orbit in support of possible repairs to the starboard Solar Alpha Rotary Joint (SARJ) which is malfunctioning.
Several items were returned with Atlantis: A malfunctioning Control Moment Gyroscope (CMG) that was swapped out with a new one during STS-118, and the empty Nitrogen Tank Assembly will be placed in the orbiter's payload bay, along with a trundle bearing from the Starboard SARJ that was removed during an EVA performed by Expedition 16.

Famous quotes containing the word mission:
“I cannot be a materialist—but Oh, how is it possible that a God who speaks to all hearts can let Belgravia go laughing to a vicious luxury, and Whitechapel cursing to a filthy debauchery—such suffering, such dreadful suffering—and shall the short years of Christ’s mission atone for it all?”
—D.H. (David Herbert)
