The mission is named for Professor Giuseppe (Bepi) Colombo (1920-1984), an Italian mathematician and engineer.
Professor Colombo suggested to NASA how to use a gravity-assist swing-by of Venus to place the Mariner 10 spacecraft in a solar orbit that would allow it to fly by Mercury three times in 1974-5.
It will take two Russian Soyuz-Fregat rockets to launch all the spacecraft.
