When the International Space Station (ISS) was redesigned again in 1993, NASA & the Italian Space Agency decided to expand the original Mini-Pressurized Logistics Module design. The new MultiPurpose Logistics Module is twice as long and an carry up to 9000kg of cargo to ISS. The European Space Agency also became a partner, since Alenia Spazio would use the same pressurized module and some thermal subsystems in the Columbus Orbiting Facility as well. In return, ESA provided three environmental control & life-support system units for use in the Multipurpose Logistics Module.

Inside the MPLM. The module carries up to sixteen refrigerator-sized (203 x 105cm) payload racks, five of which may contain refrigerators/freezers. Other so-called "Express Racks" (visible on top of the picture) can be outfitted with lockers for small experiments. Additional cargo can be carried in center aisle stowage containers.

Italy delivered the first “Leonardo” Multi-Purpose Logistics Module to NASA in July 1998. Two more module -- “Rafaelo” and “Donatello” -- will also be delivered under the $300-million contract. Italian astronauts will receive greater use of the Station as well as crew training for two more ASI astronauts in return for the MPLM.
