HIBARI (satellite)
Japanese microsatellite
HIBARI is a space mission by Japan for a microsatellite that would test a new attitude control (orientation) method to achieve high accuracy pointing for its small telescope, and was launched on 9 November 2021 by an Epsilon launch vehicle as part of the Innovative Satellite Technology Demonstration Program-2 mission.[1] The key technology to be tested on HIBARI is called "Variable Shape Attitude Control" (VSAC), and it is based on reaction torque by rotating its four solar array paddles.
