BepiColombo will be ESA's first mission to Mercury. Due for launch in 2018, the mission will take approximately 6 years to arrive at Mercury, after which it will endure temperatures as high as 350 degrees during its 1 year nominal mission and possible 1 year extension. BepiColombo consists of two separate spacecraft that will orbit the planet. ESA is building the Mercury Planetary Orbiter (MPO), and the Japanese space agency ISAS/JAXA will contribute the Mercury Magnetospheric Orbiter (MMO). The MPO will study the surface and internal composition of the planet, while MMO will study Mercury's magnetosphere.

Plasma Wave Instrument

PWI will provide remote-sensing observations of electric fields, plasma waves, and radio waves in the Hermean magnetosphere and exosphere. The PWI consists of three sets of receivers (Electric Waveform Onboard, EWO, Spectroscopie Ondes Radio & Bruit Electrostatique Thermique, SORBET, and Active Measurement of Mercury's Plasma, AM2P), connected to two sets of electric field sensors (Mercury Electric Diled In-Situ Tool, MEFISTO and Wire-Probe anTenna, WPT) and two kinds of magnetic field sensors (Low Frequency Search Coils, LF-SC and Dual-Band Search Coil, DB-SC).
