ESA unveils third mission to Mercury to investigate water ice and volcanoes

The BepiColombo spacecraft, which will become the third probe to visit Mercury, has been unveiled ahead of a mission that will tackle some of the deepest mysteries of our solar system.

The spacecraft, scheduled to launch in October 2018, will investigate the existence of water ice at Mercury’s poles and its volcanoes, and attempt to explain the surprising discovery that the solar system’s smallest planet appears to be shrinking. Mercury remains the most elusive of the solar system’s inner planets.

BepiColombo is a joint venture between ESA and the Japanese space agency, Jaxa, and comprises a pair of spacecrafts (one per agency) that will be bolted together in a 6.4-metre-high stack before its launch from Kourou in French Guiana.
