Kibo's Extravehicular Activity procedure development test No. 5 (OPS #5)
Kibo's Extravehicular Activity (EVA) procedure development test No. 5 (OPS #5) was conducted in the Weightless Environment Test Building (WET) at Tsukuba Space Center (TKSC) from November 17 to 22, 2003.
The purpose of the OPS #5 is to perform the procedure development*1 and design validation*2 of Kibo, the Japanese Experiment Module, and of H-II Transfer Vehicle (HTV), which is now being developed by Japan for transporting cargo to the ISS.
*1: In procedure development, procedures are developed
in advance for on-orbit assembly and maintenance of the ISS.
What is OPS #5?
Kibo's elements will be launched to orbit in the years 2006 and 2007 in three Space Shuttle flights and will be assembled using the manipulator and EVA.
This test is conducted to establish more efficient Kibo assembly EVA procedures by confirming the details, such as assembly order and how the EVA astronauts move, and the time needed for these operations.
The purposes of this test are to develop the procedures related to Kibo Experiment Logistics Module Exposed Section (ELM-ES) and its onboard Exposed Facility payloads, and to establish EVA on-orbit assembly procedures after the launch of the ELM-ES. It also seeks to confirm the validity of EVA procedures for the Un-pressurized Logistic Carrier (ULC) of the H-II Transfer Vehicle (HTV).
In this test, astronauts in underwater space suits* confirm and validate assembly procedures using a full-scale mockup of Kibo and related tools located in the water pool in the Weightless Environment Test building (WET) in TKSC.
*An underwater space suit is a normal space suit remodeled for underwater use.
Description of OPS #5
OPS #5 will be conducted to validate EVA procedures related to Kibo's ELM-ES and Un-pressurized Logistics Carrier (ULC) of the HTV. JAXA astronaut Wakata and NASA astronauts Leroy Chiao and David Wolf will participate as test subjects.
Astronauts work in the pool for three to four hours each day.
The primary verification procedures are as follows.
The primary validation procedures are as follows.
The testing was opened to the press on November 19, 2003, with astronaut Wakata in the underwater space suit conducting the test and astronaut Hoshide providing an explanation.
