"BepiColombo" is a joint mission of the
European Space Agency and
JAXA to the planet
Mercury. The mission comprises two satellites to be launched together: the "
Mercury Planetary Orbiter" and the "
Mercury Magnetospheric Orbiter" . The mission will perform a comprehensive study on Mercury, including its magnetic field, magnetosphere, interior structure and surface. It is scheduled to launch in
January 2017. The mission was approved in
February 2007 as part of the
Cosmic Vision programme.
BepiColombo is named after
Giuseppe Colombo , scientist, mathematician and engineer at the
University of Padua,
Italy, who first implemented the interplanetary gravity-assist maneuver during the
1974 "
Mariner 10" mission, a technique now commonly used by planetary probes.
The mission involves three components:
The prime contractor for
ESA is
EADS Astrium. ESA is responsible for the overall mission, the design, development assembly and test of the propulsion and
MPO modules, and the launch. The two orbiters are planned to be launched together on an
Ariane 5 launch vehicle in January 2017. The spacecraft will have a six-year interplanetary cruise to Mercury using solar-electric propulsion and gravity assists from
Earth,
Venus and eventual gravity capture at Mercury. ESA's
Cebreros 35-metre ground station is planned to be the primary ground facility for communications during all mission phases.
Arriving in Mercury orbit in 1
January 2024,
MMO and MPO satellites will then separate and observe Mercury in collaboration for 1 year, with a possible 1-year extension. The orbiters will be equipped with scientific instruments provided by various
European countries and
Japan. It will characterise the huge liquid iron core and will complete gravity and magnetic field mappings.
Russia will provide a gamma ray and neutron spectrometers to verify the existence of water ice in polar craters that are permanently in shadow from the Sun's rays.
