The Nano-Japan Astrometry Satellite Mission for Infrared Exploration (Nano-JASMINE) is an astrometric microsatellite developed by the National Astronomical Observatory of Japan, with contributions by the University of Tokyo Intelligent Space Systems Laboratory. , the satellite was planned for launch together with CHEOPS (Characterising Exoplanets Satellite) in 2019. However, this launch took place (in December 2019) without Nano-JASMINE as one of the three piggyback payloads. Some sources name 2021 as the launch year of the satellite.
