Discovery's payload bay doors are open to reveal the Multi-Purpose Logistics Module Leonardo which has returned.

In the Orbiter Processing Facility bay 2, Discovery’s payload bay doors are open to reveal the Multi-Purpose Logistics Module Leonardo, which has just returned from its first round trip to the International Space Station on mission STS-102. Behind it to the left is the integrated cargo carrier. Attached to the length of the payload bay, in front of Leonardo, is the robotic arm that was used to remove and position Leonardo on the ISS. Leonardo will be lifted from the payload bay and transferred to the SSPF to prepare it for future missions. The MPLM serves as a cargo van, carrying equipment and supplies to the Space Station
