MPLMs VS ATVs
NASA rejects non-Shuttle answers to stranded ISS instrument, Flight Global
“To make room for AMS in the orbiter’s payload bay the ISS cargo rescheduling idea was to move equipment from the bay’s interior into a Multi Purpose Logistics Module (MPLM), which is transported by Shuttle, or ESA’s ATV.”
Editor’s note: MPLMs are only carried to/from ISS by Space Shuttles. Portions of the ATV’s cargo section structure are based on MPLM designs – but they are not MPLMs.
