百束 泰俊
Yasutoshi Hyakusoku
When I was a child, I saw the film Apollo 13 and was fascinated by the ingenuity and spirit of challenge of people working in space, so I became a JAXA engineer. Through the development of several Earth observation satellites, I came to realize that Earth observation data (space big data) should be more useful to society, but that it is not yet being utilized to its full potential.
Just as my own feelings have gradually changed from "space as a dream" to "space as useful to society", it can be said that space big data has now become a driver for solving social problems and evolving human life.
As a bridge between technology and society, I would like to work with various people to create an exciting future.
