The lab uses lasers and balloons to test the theory of gravity with high precision.
AboutAbout the lab
Testing the laws of physics on the front lines of space science.
The Kokubun Lab is the lab of Prof. Kokubun, who is an Associate Professor at the Institute of Space and Astronautical Science (ISAS), JAXA, and also a Specially Appointed Associate Professor in the Department of Physics at Institute of Science Tokyo.
The lab's research takes place at JAXA's Institute of Space and Astronautical Science in Sagamihara, Kanagawa Prefecture.
The lab has long been involved in developing X-ray and gamma-ray observation instruments that capture high-energy phenomena in the universe, and recently it has been working on experiments that use lasers and balloons to test general relativity with high precision.
