At the Uchinoura Space Center in Japan, Solar-B is mounted to the third-stage motor of the rocket that will carry the satellite into space. The spacecraft will circle Earth at least three years, studying the solar magnetic field that fuels the sun's explosive activity. NASA helped in the development, funding and assembly of the spacecraft's three science instruments. Led by the Japan Aerospace Exploration Agency, Solar-B is collaboration among the space agencies of Japan, the United States, United Kingdom and Europe.
