Vital link between Earth and orbit
The Multi-purpose Pressurised Logistics Module (MPLM) will provide a crucial link between Earth and the Space Station.
Derived from Spacelab, Europe's space laboratory which flew on 22 Shuttle missions between 1983 and 1988, the MPLM is the only logistics module capable of transporting and returning complete scientific payload racks to and from the Space Station, enabling the conduction of science activities.
Each MPLM can hold up to 16 payload racks and carry a total of 20 000 pounds of cargo; five of the racks can be refrigerator/freezers. Once the module is released from the Shuttle's cargo bay and berthed to the Station, the astronauts can work inside, transferring scientific payloads and other supplies and materials freely between the MPLM and the Station's other research and living areas.
The ESA-supplied Environmental Control and Life Support System (ECLS) is a key element of the MPLM - a sophisticated subsystem that provides comfortable working conditions for the astronauts.
Its main functions include the distribution of fresh air throughout the MPLM, temperature, monitoring, pressure control, fire detection and suppression, and support to contamination monitoring.

Raffaello is one of three MPLM flight units. Leonardo made its debut trip to the Space Station on an earlier mission in March to deliver the first major laboratory experiments as well as key equipment and crew supplies. The Donatello module is due for its first trip in July. Each module is designed to perform 25 missions during their 10-year operational life spans.
The modules have been developed through an agreement between NASA and the Italian Space Agency, Agenzia Spaziale Italiana (ASI). Prime contractor, Alenia Spazio, is also responsible for the development of ESA’s Columbus primary structure derived from the main MPLM structure. Astrium Dornier is working alongside ESA on the ECLS.
