Multi-Purpose Logistics Module
The Muscle Atrophy Research and Exercise System (MARES), part of the Human Research Facility (HRF), was launched on 5 April 2010 (STS-131) in a stowed position inside the HRF MARES Rack, integrated into a Multi-Purpose Logistics Module (MPLM) and transported to the International Space Station. When deployed, MARES was attached to the seat tracks of an International Standard Payload Rack (ISPR) located in the Columbus Laboratory.
