Multi-Purpose Logistics Module
Ferguson made his third and last flight as a NASA astronaut, Commanding STS-135, the final mission of the Space Shuttle. 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. He returned to Earth after 12 days in space.
