The BepiColombo mission, a joint European and Japanese effort, is expected to enter orbit around Mercury in November.[^2] The composite spacecraft launched on October 20, 2018, carrying the Mercury Planetary Orbiter, the Mercury Magnetospheric Orbiter, and the Mercury Transfer Module.[^1]

Once in orbit, the two science orbiters will separate and begin mapping the planet from different altitudes. NASA's Messenger spacecraft, which orbited Mercury from 2011 to 2015, provided earlier measurements that researchers are using to prepare for BepiColombo's observations.[^3]
