The L-band synthetic aperture radar (SAR) satellite, ALOS-2 (Daichi-2), has a capability for educational purposes. The radar aboard ALOS-2, named PALSAR-2, has a wavelength of 24 cm, compatible with a makeable reflector size for children. In addition, as the spatial resolution of the radar is approximately 3 m, children can easily draw a letter in the radar image by deploying their own reflectors in the schoolyard. We have developed a sufficiently reflective corner reflector (CR) that can be easily built by children. In experiments, we clarified that ALOS-2 can detect reflected waves from a CR with a side length of three times the radar wavelength. We also developed free software that enables children and their educators to analyze most earth observation satellite data including ALOS-2 PALSAR-2 data. In 2014, we established an educational program called “Let's expose ourselves on Daichi-2 data” with the YAC-J (Young Astronauts Club Japan) and EORC (Earth Observation Research Center), JAXA. We have also held seminars for educators in various places in Japan. As a result, more than 20 groups have implemented the program. We conclude that this program enables children and their educators to feel a connection to space and fosters their interest in their native environments.
