What is Kibo's total system test? |
|
overall view (components are combined
through cables and lines.) |
Kibo's total system test checks functions and performance of the entire
Kibo with all components (Pressurized Module (PM), Exposed Facility (EF),
Experiment Logistics Module-Exposed Section (ELM-ES), Remote Manipulator
System (JEMRMS) and Inter-orbit Communication System (ICS)) connected. These
components were manufactured and evaluated in individual element tests by
each contractor. The total system test has been conducted since PM arrived
at Tsukuba Space Center

Several tasks in Kibo's total system test are shown below.
|
|
Preparation and confirmation before the test |
Kibo's components were first checked to ensure they were not damaged during
transport from factories and then connected. System racks were installed
in the PM, and the JEMRMS was attached to the outside of the PM. Other components
were connected only through cables since they cannot sustain mechanical
stress on Earth. Coolant lines were also connected between PM and EF. The
functional connection of all components was then confirmed.
|
|
International verification test |
Electrical, audio and data interfaces between Kibo and the NASA module of
the International Space Station were verified. In this test, NASA equipment
was used to simulate the NASA module.
|
|
Interface test |
Command, telemetry, thermal control, and power supply were verified through
components of Kibo; control equipment inside the PM actually operated mechanical
parts of EF and ELM-ES.
|
|
ICS-EF compatibility test |
ICS-EF was evaluated to ensure proper electrical and structural connection
to ELM-ES.

Environment (ventilation) test |
In this test, Kibo was evaluated to determine if it provides an adequate
environment for manned activities (evaluated ventilation performance inside
Kibo).
|
|
Others |
ELM-PS was measured during this test.
| Future
Plans |
The total system test is almost completed. Evaluation of data acquired in
the test, separating components and uninstalling of racks have begun. After
completing this test, checks will be made for air leaks and tests combining
the operation system and payloads will be conducted. Around 2003, Kibo will
be shipped to NASA Kennedy Space Center, connected to ISS modules, and tested.
