Multi-Purpose Logistics Module
Multi-Purpose Logistics Module, which was built by the Italian Space
Agency (ASI), is the first of three such pressurized modules that
will serve as the International Space Station's "moving vans,"
carrying laboratory racks filled with equipment, experiments and
supplies to and from the station aboard the space shuttle.
reusable logistics modules function as both a cargo carrier and
a space station module when they are flown. Mounted in the space
shuttle's cargo bay for launch and landing, they are berthed to
the station using the shuttle's robotic arm after the shuttle has
docked. While berthed to the station, racks of equipment are unloaded
from the module and then old racks and equipment may be reloaded
to be taken back to Earth.
Leonardo will be filled with equipment and supplies to outfit the
U.S. Destiny Laboratory Module, which was delivered by STS-98. The
MPLM is a pressurized module that carries to orbit six U.S. Laboratory
System Racks, Resupply Stowage Platforms (RSP), Resupply Stowage
Racks and a Human Research Facility (HRF) rack. The racks and RSPs
contain crew rotation hardware, avionics hardware, spare hardware,
stowage items, Crew Health Care System (Checs) items, the ISS ergometer,
Mobile Servicing System (MSS) Robotic Workstation (RWS) equipment
and HRF experiment unique equipment.
The Integrated Cargo Carrier, or ICC, is an externally mounted, unpressurized,
aluminum flatbed pallet, coupled with a keel-yoke assembly, that
expands the shuttle's capability to transport cargo.
the ICC is the carrier which transports the Early Ammonia Servicer,
the Rigid Umbilical, The Lab Cradle Assembly with the Module to
Truss Structure Attach System -A, the Pump Flow Control Assembly
and the External Stowage Platform.
DTO 700-14 -
Single String Global Positioning System
The purpose of the Single String Global Positioning System DTO is to evaluate
the performance of a Global Positioning System, or GPS, receiver
being developed for operational use by the shuttle. The Miniaturized
Airborne GPS Receiver was designed and manufactured by Rockwell
Collins for military aircraft. It has been modified to work in the
space environment, and communicate with the shuttle's computers.
GPS data will be downlinked during all mission phases. When development,
flight test and certification activities are complete, two more
GPS receivers may be added to provide a fully redundant replacement
for existing Tactical Air Navigation systems, and improve orbiter
capabilities for orbit and entry navigation.
