ESA's BepiColombo Mission

General Overview with a Special Focus on ESA's Mercury Planetary Orbiter

On Things to Come Webinars

Dr Johannes Benkhoff
European Space Agency, ESA

24 February 2021
9 am CET -- 4 pm GMT+8



BepiColombo was launched on 20 October 2018 the BepiColombo from the European spaceport in French Guyana and is now on route to Mercury to unveil Mercurys secrets. BepiColombo with its state of the art and very comprehensive payload will perform measurements to increase our knowledge on the fundamental questions about Mercurys evolution, composition, interior, magnetosphere, and exosphere. BepiColombo is a joint project between the European Space Agency (ESA) and the Japanese Aerospace Exploration Agency (JAXA) and consists of two orbiters, the Mercury Planetary Orbiter (MPO) and the Mercury Magnetospheric Orbiter (Mio).  

The BepiColombo will perform nine planetary flybys during its 7-year long journey to the innermost terrestrial planet. During this cruise phase BepiColombo is in a so called stacked configuration where the two spacecraft are sitting on top of a transfer spacecraft. Only in late 2025, this configuration is abandoned and the individual elements spacecraft are brought in to their final Mercury orbit: 480x1500km for MPO, and 590x11640km for Mio. The mission has been named in honor of Giuseppe (Bepi) Colombo (19201984), who was a brilliant Italian mathematician, who made many significant contributions to planetary research and celestial mechanics.

On its way BepiColombo has several opportunities for scientific observations - during the cruise into the inner solar system and during nine flybys (one at Earth, two at Venus and six at Mercury). However, since the spacecraft is in a stacked configuration during the flybys only some of the   instruments on both spacecraft will perform scientific observations.  

A status of the mission and its instruments with special emphasis on the MPO (since further talks on Mio and dedicated instruments will follow in the weeks after) will be given.


About Johannes Benkhoff

Johannes Benkhoff is planetary physicist working in the field of computational modeling of surface - interior interactions of small bodies in the Solar System for more than 30 years. He got his PhD in 1992 at University of Münster and obtained a scholarship from the German Science Foundation (DFG) to work as a post-doc for three years at the SwRI institute in Texas, USA. After that he became a research scientist at the German Aerospace Centre, DLR, before he moved to ESA in 2004. Since 2006 he is the project scientist of the joint ESA - JAXA BepiColombo mission. 

Research Areas:
· Stability of convection in the Earth mantle
· computational modeling of the physics and chemistry of sublimation processes of porous, dusty, multi-component ices in the Solar System
· Comet nucleus modeling, Spectroscopy
· Stability of ice investigations in polar craters on Mercury and in near surface layers of Mars
· Planet Mercury in general

Co-Investigator:
VIRTIS (Rosetta Orbiter Instrument), MUPUS (Rosetta Lander Instrument), CONTOUR (NASA Discovery mission to study the variety of comets), VIRTIS (Venus Express), and MERTIS and SIMBIO-SYS (both BepiColombo) and Project Scientist of BepiColombo

Awards:
Postdoc scholarship from the German science foundation for two years of studies at the SwRI in San Antonio, Texas, USA. Asteroid, 1998 SM58, was named “13332 Benkhoff”
