EXPRESS is the acronym
for EXpedite The PRocessing of Experiments to Space Station. The
EXPRESS program consists of two separate systems: the EXPRESS rack
for pressurized payloads and the EXPRESS pallet for attached payloads.
EXPRESS pallet for attached payloads is provided by Brazil
as a participant through a bilateral arrangement with the United
States and the Brazilian Space Agency, which is also known as AEB.
Attached Payloads are located
outside of the pressurized volume of the space station on the truss
or the Japanese Experiment Module Exposed Facility, or JEM EF. The
EXPRESS Pallet can be located at any site on the truss segment and
has six robotically replaceable adapters for payloads or payload
Attached payloads may use
the station power, command and data handling system and video. The
crew will interface using robotics for installation and removal
of the attached payloads, with no nominal extravehicular activity
