Spacecraft such as satellites that pursue various missions in space are launched by a launch vehicle after “designed”, “manufactured”, and “tested”. They go through extremely severe environments during launch and in space. To help them perform successfully even in such severe environments, it is imperative to verify their endurance, functions, and performances in environmental tests on ground. And it is our responsibility at the Environmental Test Technology Unit to support the successes of those “tests”.

Environmental Test Technology Unit is in charge of some of the largest facilities in Japan for conducting various environmental tests, and maintains and manages these test facilities so that they can be provided to users in the best possible condition. Furthermore, we are conducting research and development of testing technologies based on the knowledge we have accumulated through past tests, and are examining new evaluation methods and environmental prediction methods, while also working to develop more effective and efficient testing facilities and methods.
Through these testing technologies, the Environmental Test Technology Unit will support the success of various increasingly sophisticated spacecraft missions, contribute to the development of the space industry throughout Japan, and meet people's expectations by creating new value.

Operations and Management of Environmental Test Facilities

To support the success of JAXA’s diverse spacecraft missions, we are steadily conducting environmental tests using environmental test facilities. In addition, we are systematically planning upgrades and functional enhancements to these facilities.
We are promoting the shared use and broader utilization of test facilities beyond the aerospace sector by leveraging private sector resources.

Research and Development

To support increasingly sophisticated spacecraft missions, we are engaged in R&D aimed at enhancing the fundamental technologies and functions of environmental test facilities. In addition, we are working to apply and expand the technologies cultivated through the R&D of environmental test facilities to other industries beyond aerospace, thereby creating new value.
