An artist’s impression of the ESA/JAXA BepiColombo spacecraft in cruise configuration, with Mercury in the background. On its 7.2 year journey to the innermost planet, BepiColombo will fly by Earth once, Venus twice and Mercury six times before entering into orbit. The MTM module is shown with ion thrusters firing, and with its solar wings extended, spanning about 100 feet (30 m) from tip-to-tip. The 24.6-foot (7.5 m) long solar array of the MPO orbiter in the middle is seen extending to the top. The Mio orbiter is hidden inside the sunshield in this orientation.
