MPLM: flexibility in pressurized cargo transportation

Abstract

The Mini Pressurized Logistics Module (MPLM) will support the International Space Station (ISS) programme by providing accommodation for pressurized cargo necessary to accomplish both the assembly and the utilisation phase. The design and development of the MPLM is based on payload accommodation “flexibility” and minimal on-ground reconfiguration. One of the most important tasks of the MPLM design activity is to implement the interface requirements between the MPLM and the payloads while still satisfying the functional interfaces with the Space Station and the NSTS. The three MPLM units to be delivered to NASA will be able to support the necessary functions for assisting active payloads, together with storage for passive payloads. Today, the MPLM programme is undergoing the test campaign, while the design can be considered 90% completed and baselined. The paper will describe the MPLM design peculiarities in providing accommodation “flexibility” and the ability to support active missions in the NSTS as well as at the Space Station. In addition, the present status of the MPLM programme is summarised at two years from the delivery of the first unit scheduled for March 1998.
