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's Intelligent Space Systems Laboratory (ISSL).

[2] Its exterior is covered with Gallium arsenide (GaAs) solar cells providing approximately 20 watts of power.

[8] Nano-JASMINE is Japan's first and the world's third astrometric survey spacecraft, following Hipparcos (1989) and Gaia (2013), both launched by the European Space Agency (ESA).

Given the time difference between these missions, combining the data sets of Nano-JASMINE and Hipparcos will constrain the positions of stars whose current positions are poorly known owing to uncertainty in their motion since being measured by Hipparcos, and should provide an order-of-magnitude increase in the accuracy of proper motion measurements (approximately 0.1 mas/year; 0.2 mas/year for stars brighter than 9 magnitude).

The launch was originally contracted for August 2011,[11] but was delayed to the November 2013 to March 2014 time frame.
