Mission to Mercury launches successfully

A joint Japanese–European mission that is set to be the second ever to enter Mercury’s orbit launched successfully on 19 October from Kourou, French Guiana.

The €1.6-billion (US$1.8-billion) mission, called BepiColombo, will insert two probes into the planet’s orbit in 2025, after several fly-bys of Earth, Venus and Mercury itself.

One probe, built mainly by the European Space Agency (ESA), will study Mercury’s surface and its inner structure.

The other, built by the Japan Aerospace Exploration Agency, will focus on the planet’s magnetic field and its interaction with the solar wind.

Hours after launch, BepiColombo successfully deployed its antennas and two 15-metre-long “solar wings”, ESA said. The craft also took several “space selfies” using three on-board monitoring cameras.
