Innovative Satellite Technology Demonstration-2

KOSEN-1 is a technology demonstration satellite that will test the deployment of an antenna for observing radio waves emitted from the planet Jupiter.^[1] It is a 2U CubeSat, and carries a 7 m (23 ft) antenna. The CubeSat was jointly developed by the National Institute of Technologies in Japan.^[1] National Institute of Technologies is known as 'kosen' in Japanese. KOSEN-1 was launched on 9 November 2021 by an Epsilon launch vehicle, as part of the Innovative Satellite Technology Demonstration-2 mission.^[2]^[3]
