Extravehicular Activity procedure development test No. 3 (OPS #3)||
Kibo's Extravehicular Activity procedure development test No. 3 (OPS #3)
was conducted in the Weightless Environment Test Facility at Tsukuba Space Center
from November 5 to 26, 2001. When the test was opened to the press on November
12, astronaut Koichi Wakata participated in the test wearing an underwater space
suit, and astronaut Naoko Sumino gave a description to the press.
Kibo's Extravehicular Activity procedure development test No. 3 (OPS #3)?|
the Japanese Experiment Module, will be launched to orbit from 2006 through 2007
in three flights and will be assembled using Space Shuttle robot arm and extravehicular
Logistics Module Pressurized -Sectioin mockup

NASDA will develop EVA procedures for Kibo assembly, and NASA
will brush them up with NASDA's support. The procedures will include details of
Kibo assembly, such as how to carry EVA tools, how to remove the thermal insulation
that covers Kibo during launch phase, how the EVA astronauts move, and the time
needed for these operations.
This test is conducted to confirm the procedures that will be submitted
to NASA and to establish better assembly procedures.
Kibo's life-size mockup was located in the water pool in the weightless environment
test facility, and astronauts in underwater space suits conducted the test. The
previous test, OPS #2, was conducted from early February through early March 2001,
assuming EVAs for the Pressurized Module and Exposed Facility assembly. OPS #3
was conducted to confirm the EVA procedures for assembly of the Experiment Logistics
Module-Pressurized Section, Experiment Logistics Module-Exposed Section, Exposed
Facility, and Experiment Payloads.
This test was also conducted to confirm
the design validity of equipment that will be assembled or maintained by EVA.
NASDA astronauts Wakata, Furukawa,
Hoshide, Sumino, and NASA astronaut Joseph Tanner confirmed the subjects below
following assembly procedures similar to those in space.
OPS #3 was conducted |
One maximum three-hour dive was conducted each day.
Subjects for Procedures Confirmation
- Assembly sequence
- Astronaut translation path and time
and handhold Locations
- Tool locations
- Validity of tool selection
operation for a pair of astronauts
- Operation time
for Design Confirmation
- Handrail and handhold Locations
ORUs carrying methods
- Accessibility to EVA interfaces including bolts,
thermal insulation straps, connectors, and cable clamps.
- Visibility of
labels and indicators.
Data collected through OPS #3 will be reflected in
JEM EVA training procedures that will be conducted in the Neutral Buoyancy Laboratory
at Johnson Space Center.
Kibo's preparation is thus steadily proceeding toward
