The Leonardo Permanent Multipurpose Module (PMM) is primarily used for storage of spares, supplies and waste on the ISS, which is currently stored in many different places within the space station. The Leonardo PMM was a Multi-Purpose Logistics Module (MPLM) before 2011, but was modified into its current configuration. It was formerly one of three MPLM used for bringing cargo to and from the ISS with the Space Shuttle. The module was named after Italian polymath Leonardo da Vinci.
