A Multi-Purpose Logistics Module (MPLM) is a large pressurized container that was used on Space Shuttle missions to transfer cargo to and from the International Space Station (ISS). Two MPLMs made a dozen trips in the Shuttle cargo bay and initially berthed to the Unity and later the Harmony module on the ISS. Once attached, supplies were offloaded, and finished experiments and waste were reloaded. The MPLM was then transferred back into the Shuttle’s cargo bay for return to Earth. Three modules were built by Alenia Aeronautica for the Italian Space Agency (ASI). They were named Leonardo , Raffaello, and Donatello. [1]
The Leonardo module was modified in 2010 to turn it into the Permanent Multipurpose Module (PMM) and was permanently attached to the ISS during the STS-133 mission in March 2011. In July 2011, the Raffaello module was the primary payload on the final Space Shuttle mission. It returned with the Shuttle and was stored at the Kennedy Space Center. The Donatello module never launched. MPLMs were flown on 12 of the 37 Space Shuttle missions to the ISS.
The basic design of the MPLM was later used as the basis for two cargo spacecraft, the European Automated Transfer Vehicle and the American Cygnus.
The modules were provided to NASA under contract by the Italian Space Agency (ASI). Three MPLMs were built and delivered to NASA and have names chosen by the ASI to denote some of the great talents in Italian history: Leonardo da Vinci, Raffaello and Donatello. Although built by ASI, the modules are owned by NASA. In exchange for building the MPLMs, ASI receives access to U.S. research time on the ISS. [1]
The MPLMs have a heritage that goes back to Spacelab. [2] In addition, ESA's Columbus module, the Harmony and Tranquility ISS modules and the ATV and Cygnus resupply craft all trace their origins to the MPLMs. [2] The MPLM concept was originally created for Space Station Freedom. Initially, they were to be built by Boeing, but in 1992, the Italians announced that they would build a "Mini-Pressurized Logistics Module", able to carry 4,500 kilograms (4.5 t) of cargo. After the 1993 redesign of Freedom, the length was doubled and it was renamed the "Multi-Purpose Logistics Module". Each empty MPLM is approximately 21 feet (6.4 m) long, 15 feet (4.6 m) in diameter, weighs 4,400 kilograms (9,700 lb), and can deliver up to nine metric tons of cargo to the ISS. [1]
Donatello was a more capable module than its two siblings, as it was designed to carry payloads that required continuous power from construction through to installation on the ISS. However, Donatello was never used and some of its parts were cannibalized to convert Leonardo into the PMM. [3]
With the end of the Space Shuttle program in 2011, the Raffaello and Leonardo modules were flown a combined total of 12 times.
An MPLM is a large cylinder equipped with a common berthing mechanism at one end, and grapple fixtures to allow the Canadarm-2 to move it from the shuttle bay to a berthing port on the US Orbital Segment of the ISS.
In order to provide power to equipment and experiments inside the MPLM during launch, the MPLM could be connected to the Shuttle's power supply by means of the Remotely Operated Electrical Umbilical (ROEU). The umbilical was mounted on the starboard side payload bay sidewall longeron, and was a folding arm umbilical that connected to the MPLM while it was in the payload bay. The arm was disconnected and retracted prior to the MPLM being removed for placement on the ISS and then reconnected once the MPLM was placed back inside the payload bay.
Since the module names are also the names of three of the four Teenage Mutant Ninja Turtles, the NASA MPLM Group approached Mirage Studios artist A.C. Farley to design a logo featuring Raphael in an astronaut flight suit. [4] There were cloisonné pins produced, as well as stickers and embroidered patches. Because the Ninja Turtles were created by Mirage Studios and owned by them at the time (now owned by Paramount Global, formerly ViacomCBS, via Nickelodeon), NASA gave Mirage the copyright to the logo in exchange for the use of the studio's character on it.

The following are the specifications of the MPLM:
The Donatello MPLM has been converted by Lockheed Martin into a Habitat Ground Test Article (HGTA) Lunar habitat prototype [7] which is located at NASA KSC. Leonardo is permanently attached to the ISS as PMM and should reenter in the atmosphere with it. Raffaello is located at an Axiom Space facility near Houston, in preparation to undergo work to become an element for the Axiom Commercial Space Station. [8] [9]
Spacelab was a reusable laboratory developed by European Space Agency (ESA) and used on certain spaceflights flown by the Space Shuttle. The laboratory comprised multiple components, including a pressurized module, an unpressurized carrier, and other related hardware housed in the Shuttle's cargo bay. The components were arranged in various configurations to meet the needs of each spaceflight.
Columbus is a science laboratory that is part of the International Space Station (ISS) and is the largest single contribution to the ISS made by the European Space Agency (ESA).
STS-100 was a Space Shuttle mission to the International Space Station (ISS) flown by Space Shuttle Endeavour. STS-100 launch on 19 April 2001, and installed the ISS Canadarm2 robotic arm.
STS-105 was a mission of the Space Shuttle Discovery to the International Space Station, launched from Kennedy Space Center, Florida, 10 August 2001. This mission was Discovery's final mission until STS-114, because Discovery was grounded for a refit, and then all Shuttles were grounded in the wake of the Columbia disaster. The refit included an update of the flight deck to the glass cockpit layout, which was already installed on Atlantis and Columbia.
STS-108 was a Space Shuttle mission to the International Space Station (ISS) flown by Space Shuttle Endeavour. Its primary objective was to deliver supplies to and help maintain the ISS.
STS-121 was a 2006 NASA Space Shuttle mission to the International Space Station (ISS) flown by Space ShuttleDiscovery. The main purposes of the mission were to test new safety and repair techniques introduced following the Columbia disaster of February 2003 as well as to deliver supplies, equipment and German European Space Agency (ESA) astronaut Thomas Reiter to the ISS.
The Unity connecting module, also known as Node 1, is the first U.S.-built component of the International Space Station (ISS). It connects the Russian and United States segments of the station, and is where crew eat meals together.
Harmony, also known as Node 2, is the "utility hub" of the International Space Station. It connects the laboratory modules of the United States, Europe and Japan, as well as providing electrical power and electronic data. Sleeping cabins for four of the crew are housed here.
Tranquility, also known as Node 3, is a module of the International Space Station (ISS). It contains environmental control systems, life support systems, a toilet, exercise equipment, and an observation cupola.
Expedition 11 (2005) was the 11th expedition to the International Space Station, using the Soyuz TMA-6, which stayed during the expedition for emergency evacuation.
STS-133 was the 133rd mission in NASA's Space Shuttle program; during the mission, Space Shuttle Discovery docked with the International Space Station. It was Discovery's 39th and final mission. The mission launched on February 24, 2011, and landed on March 9, 2011. The crew consisted of six American astronauts, all of whom had been on prior spaceflights, headed by Commander Steven Lindsey. The crew joined the long-duration six person crew of Expedition 26, who were already aboard the space station. About a month before lift-off, one of the original crew members, Tim Kopra, was injured in a bicycle accident. He was replaced by Stephen Bowen.
STS-128 was a NASA Space Shuttle mission to the International Space Station (ISS) that launched on August 28, 2009. Space ShuttleDiscovery carried the Multi-Purpose Logistics Module Leonardo as its primary payload. Leonardo contained a collection of experiments for studying the physics and chemistry of microgravity. Three spacewalks were carried out during the mission, which removed and replaced a materials processing experiment outside ESA's Columbus module, and returned an empty ammonia tank assembly.
STS-131 was a NASA Space Shuttle mission to the International Space Station (ISS). Space ShuttleDiscovery launched on April 5, 2010, at 6:21 am from LC-39A, and landed at 9:08 am on April 20, 2010, on runway 33 at the Kennedy Space Center's Shuttle Landing Facility. The mission marked the longest flight for Space Shuttle Discovery.
The Raffaello MPLM, also known as MPLM-2, was one of three Multi-Purpose Logistics Modules which were operated by NASA to transfer supplies and equipment to and from the International Space Station. Raffaello was used for four of twelve MPLM flights to the space station, with Leonardo being used for the remainder. It was first launched on 19 April 2001, aboard the STS-100 mission flown by Space ShuttleEndeavour, and made its third flight in July 2005, aboard Discovery on STS-114. Raffaello's final flight was aboard Space ShuttleAtlantis on the STS-135 mission, the last flight of the Space Shuttle.
The Space Systems Processing Facility (SSPF), originally the Space Station Processing Facility, is a three-story industrial building at Kennedy Space Center for the manufacture and processing of flight hardware, modules, structural components and solar arrays of the International Space Station, and future space stations and commercial spacecraft. It was built in 1992 at the space complex's industrial area, just east of the Operations and Checkout Building.
Cygnus is an expendable American cargo spacecraft used for International Space Station (ISS) logistics missions. Cygnus was developed by Orbital Sciences Corporation, partially funded by NASA under the agency's Commercial Orbital Transportation Services (COTS) program. To create Cygnus, Orbital paired the Multi-Purpose Logistics Module, built by Thales Alenia Space and previously used by the Space Shuttle for ISS logistics, with a service module based on Orbital's GEOStar, a satellite bus. After a successful demonstration flight in 2013, Orbital was chosen to receive a Commercial Resupply Services (CRS) contract. A larger Enhanced Cygnus was introduced in 2015. Orbital Sciences was renamed Orbital ATK in 2015 and Northrop Grumman purchased Orbital in 2018 and has continued to operate Cygnus missions.
STS-135 was the 135th and final mission of the American Space Shuttle program. It used the orbiter Atlantis and hardware originally processed for the STS-335 contingency mission, which was not flown. STS-135 launched on July 8, 2011, and landed on July 21, 2011, following a one-day mission extension. The four-person crew was the smallest of any shuttle mission since STS-6 in April 1983. The mission's primary cargo was the Multi-Purpose Logistics Module (MPLM) Raffaello and a Lightweight Multi-Purpose Carrier (LMC), which were delivered to the International Space Station (ISS). The flight of Raffaello marked the only time that Atlantis carried an MPLM.
Kounotori 2, also known as HTV-2, was launched in January 2011 and was the second flight of the Japanese H-II Transfer Vehicle to resupply the International Space Station (ISS). It was launched by the H-IIB Launch Vehicle No. 2 manufactured by Mitsubishi Heavy Industries (MHI) and JAXA. After the supplies were unloaded, Kounotori 2 was loaded with waste material from ISS, including used experiment equipment and used clothes. Kounotori 2 was then unberthed and separated from the ISS and burned up upon reentering the atmosphere on 30 March 2011.
The Leonardo Permanent Multipurpose Module (PMM) is a module of the International Space Station. It was flown into space aboard the Space Shuttle Discovery on STS-133 on 24 February 2011 and installed on 1 March. Leonardo is primarily used for storage of spares, supplies and waste on the ISS, which was until then stored in many different places within the space station. It is also the personal hygiene area for the astronauts who live in the US Orbital Segment. The Leonardo PMM was a Multi-Purpose Logistics Module (MPLM) before 2011, then was modified into its current configuration. It was formerly one of two MPLM used for bringing cargo to and from the ISS with the Space Shuttle. The module was named for Italian polymath Leonardo da Vinci.
The US Orbital Segment (USOS) is the name given to the components of the International Space Station (ISS) constructed and operated by the United States National Aeronautics and Space Administration (NASA), European Space Agency (ESA), Canadian Space Agency (CSA) and Japan Aerospace Exploration Agency (JAXA). The segment consists of eleven pressurized components and various external elements, almost all of which were delivered by the Space Shuttle.
