Raffaello was the primary cargo of STS-135.
Space Shuttle Atlantis carried the Multi-Purpose Logistics Module Raffaello on STS-135, the final mission of the Space Shuttle program. Launched on July 8, 2011, the flight delivered supplies and equipment to the International Space Station. Raffaello was removed from Atlantis’s payload bay with the station’s Canadarm2 and berthed to the Harmony node for cargo transfers.
Raffaello carried 16 resupply racks, including platforms and storage racks filled with station provisions. After the cargo was unloaded, astronauts packed the module with unneeded equipment and waste for return to Earth. Raffaello had previously flown several times, but STS-135 was the only mission on which Atlantis carried an MPLM. Donatello and Leonardo were the other MPLMs; Leonardo was later permanently installed on the ISS as a storage module.
