Kibo's Extravehicular Activity procedure development test No.2(OPS#2)

OPS#2 TEST
Kibo's Extravehicular Activity (EVA) procedure development test No. 2 (OPS #2) was conducted at Tsukuba Space Center from the end of November 2000 to March 6, 2001.


What is OPS#2?
Japanese Experiment Module Kibo will be launched in three separate flights from 2006 through 2007 and will be assembled by using a Space Shuttle robot arm and by EVAs.

NASDA will prepare Kibo assembly EVA procedures, and NASA will brush them up with NASDA's cooperation. The procedures will include operation procedures such as how to transfer EVA tools, how to remove the thermal insulation covers used for launching Kibo, and EVA crew translation procedures and time needed for them.

This test was conducted for assembling Kibo's Experiment Logistics Module-Pressurized Section (ELM-PS) and Pressurized Module (PM) to confirm and establish more effective procedures that will be submitted to NASA.

A life-size mockup of Kibo was installed in the water tank of the Weightless Environment Test Building, and astronauts and engineers wearing underwater space suits conducted the test.

Kibo's EVA procedure development test No. 1 (OPS #1) was conducted from January through February 2000, and EVA tools transfer procedures, installation of a portable foot restraint on Kibo, and an assembly simulation were performed.


Test activities
Astronaut Noguchi
During this test, Japanese astronaut Noguchi, together with NASA astronauts and engineers, performed the tests below following procedures similar to the assembly operations in space.
The underwater operation cycle takes up to three hours.
  • Confirm how to bring EVA tools to EVA locations.
  • Confirm the astronauts' translation route and time needed for each movement.
  • Confirm the location of handrails and handholds that are used to support astronauts' movement.
  • Evaluate the visibility at EVA locations.
  • Evaluate the usage of EVA tools.
  • Confirm temporary stowage location of tools.
  • Confirm coordinated operation with the crew inside.
  • Confirm where to wait for the next procedure.
  • Confirm time needed for EVA tasks.
Engineers from various fields.
The underwater test is conducted by one astronaut who wears an underwater space suit. Many engineers from various fields are participating in this test. Support divers help the underwater astronaut. They help astronauts to move in the water, adjust neutral buoyancy, and take records of the test. Nearly ten divers work under water simultaneously.

Various engineers such as a test conductor who controls whole the test and gives instructions to the astronaut once in a while, a medical crew that manages the health of astronauts and divers, technicians who adjust and maintain the underwater space suit, weightless environment facility engineers who manage water quality and water temperature and operate the air compressor that provides air to the space suit, engineers who prepare and confirm EVA procedures support the test, and EVA procedures are established through their cooperation.

Know how of various fields obtained through the tests will be accumulated and utilized in actually operating Kibo in several years to come.


Future schedule
The EVA procedures developed through this test will be utilized in Kibo related EVA training procedures that will be held in the Neutral Buoyancy Laboratory (NBL) in Johnson Space Center.

The third test will be held early next year. Preparations for the launch of Kibo are being promoted continuously.
