Europe and Japan at Mercury
BepiColombo is a joint ESA/JAXA mission comprising two orbiters: ESA's Mercury Planetary Orbiter and JAXA's Mercury Magnetospheric Orbiter. Together they will conduct the most comprehensive study of Mercury ever attempted.
Getting There Is the Hard Part
Reaching Mercury requires enormous speed changes. BepiColombo uses nine gravity assists — one at Earth, two at Venus, and six at Mercury itself — combined with ion propulsion to gradually slow down over seven years.
