- Storage Module 2 -
- Multi-Purpose Logistics Module (Leonardo) -
STS-224 delivered the second of three storage modules to the station, and also carried additional supplies for the station. Unlike other MPLM missions, STS-224 did not function as a utilization mission, instead acting solely for supply, and therefore only stayed 7 days. A utilization style mission was instead performed on the following mission, STS-225.
