Japan Space Systems
The Institute for Unmanned Space Experiment Free Flyer (USEF) (財団法人無人宇宙実験システム研究開発機構, Zaidanhōjin mujin uchū jikken shisutemu kenkyū kaihatsu kikō) was a Japanese space agency, which was founded by the Ministry of International Trade and Industry in 1986. Unlike NASDA, ISAS, and NAL, it was not included in the JAXA organization, which was founded in 2003. The chairperson is Ichiro Taniguchi.
In 2012, USEF merged two other organizations—Earth Remote Sensing Data Analysis Center (ERSDAC) and Japan Resources Observation System Organization (JAROS)—to form a new organization Japan Space Systems (J-spacesystems).
