Tsukuba-shi, Ibaraki Tsukuba Space Center

JAXA’s Tsukuba Space Center (TKSC), located in Tsukuba Science City, opened its doors in 1972. The TKSC, which sits on a 530,000 square-meter site, with beautiful natural surroundings, is a consolidated operations facility with world-class equipment and testing facilities.
As the center of Japan’s space network, the TKSC plays an important role in the research and development of spacecraft, such as satellites and rockets, and also controls and tracks launched satellites. As part of the International Space Station project, the Japanese Experiment Module (JEM) "KIBO" is developed and tested at TKSC. Astronaut training is also in progress at the center.
Space Technology Directorate I, the Human Spaceflight Technology Directorate, and part of the Institute of Space and Astronautical Science are located at the TKSC which implement latest research, development, and testing in the space field. It is a pivotal center for Japanese space development.

Main Facilities

13mΦSpace Chamber

(Spacecraft Integration and Test Building)
Satellites and rockets are disassembled, and their parts and systems are tested to ensure their endurance in a vacuum and in the thermal environment of space.

Large Scale Vibration Test Facility (Spacecraft Integration and Test Building)

In this building, satellites or launch vehicles undergo vibration tests by separating them into each unit or system.

Kibo engineering model
Protoflight model assembly test facility

(Space Station Test Building)
Prior to the launching of the Japanese Experiment Module "Kibo", the Space Station Test Building will be the site of such activities as functional testing of the various sub-elements of Kibo and overall system testing of the integrated elements, and interface testing with the International Space Station (ISS).

Ultrahigh Vacuum Surface Properties Test Facility
(Research and Development Building)

In this building, the impact of long-term exposure in an ultra-high vacuum environment is evaluated including clarifying the deterioration mechanism of the surface material’s characteristics, impact evaluation due to micro gas contents, and evaluating abrasion resistance of solid lubricant in the vacuum environment.
