The octagonal spacecraft is seen here at ESA’s test centre in the Netherlands, where it is being tested alongside the other elements of this dual-spacecraft mission. During cruise, it will sit above ESA’s Mercury Planetary Orbiter at the top of the BepiColombo stack, to be launched in April 2018. The Mercury Transfer Module will deliver them to Mercury using highly efficient electric propulsion. While ESA’s craft will go into a 480 x 1500 km mapping orbit around Mercury, Japan’s will enter a highly elliptical 590 x 11 640 km orbit to study the planet’s environment and its magnetic field.
