Multi-Element Integration Test-III (MEIT-III) was conducted at Kennedy
Space Center in Florida, for the Kibo Pressurized Module (PM), and
Node 2 (the connection module of the ISS main body), and the US Laboratory
Check Points and Results Confirmed in MEIT-III
||Primary Check Points
Verify that stable electric power can be supplied
from the electric equipment of Node 2 to the PM.
- Electric power was supplied normally.
- Electrical source characteristics (noise and
impedance) were measured and found to be normal.
Verify the ability to establish communications
between the central computer of the U.S. module and the PM via
- Communications was established
between the system computers. Commands and telemetry were transmitted
normally through the activation test and full test period.
Verify that the initial start-up computer, control
computer, cooling system, and environmental control system of the
PM can be activated properly from Node 2 and Destiny during Kibo's
assembly on orbit.
- Following the activation procedure (routine
procedure and backup procedure) during the on-orbit assembly,
start-up computer, control computer, and onboard equipment of
each subsystem was activated and performed properly.
- The two cooling
water circulation systems, low-temperature loop
(4.5 degrees C) and
moderate-temperature loop (17.2 degrees C) were confirmed to be functional.
control system (temperature and humidity adjustment and air circulation)
activated and performed normally.
- A software error was found in the operation
terminal when activated, but it
activated normally after rebooting.
Verify that caution and warning signals for unusual
situations such as fire and rapid decompression that may threaten
the life of the crew can be exchanged in a short time among the
Kibo PM and other modules.
- Caution and warning function tests were conducted
and confirmed that the signals were transmitted normally.
Verify that the camera image used for the Kibo's
remote manipulator system operation to be processed in the Destiny
via Node2, and transmitted to the PM.
- Video signal interface test was conducted and
confirmed that the camera image was processed and transmitted normally.
Verify that the experimental data
from Kibo's laboratory equipment can be transmitted to Destiny
via Node 2 using the large-capacity optic fiber transmission system.
- High-rate data (optic fiber) transmission
test was conducted and confirmed that the data was transmitted
- Medium rate data (Ethernet) transmission test
was conducted and confirmed that the data was transmitted normally.
- Low rate
data transmission system (1553B data bus) was confirmed to
Verify that the wire and fluid ducts
that connect Node 2 and the PM can be connected without interference.
- The wire and fluid ducts of the
actual flight module were used to confirm that the ducts could
be connected by a NASA astronaut.
The Kibo functional checks and tests will be conducted through March
of 2004 in KSC before Kibo is stored until preparation for its installation
on the Space Shuttle begins a year before the launch.
