Japan Plans Space-Based Infrared Test in 2020

On June 12, Japanese Ministry of Defense officials confirmed plans to study a space-based early missile warning system by testing an experimental infrared sensor in 2020. According to Sankei Shimbun, Tokyo will mount the two-color sensor on the Japan Aerospace Exploration Agency (JAXA)’s Advanced Optical Satellite-3 (ALOS-3), an imaging satellite. Japan began research on two-color infrared sensors in 2015 and is expected to make a decision on deploying a dedicated satellite by 2024.
