Components fabricated in the LPS workshop on their way to Mercury

The BepiColombo mission, a European and Japanese (ESA, JAXA) project to study Mercury, has been launched from Kourou in the evening of October 20th 2018. The LPS workshop has fabricated some of the elements of one of the two probes of this mission.

The cases of the electronics module for the instrument SIMBIO-SYS, carried inside the MPO probe (Mercury Planetary Orbiter), were fabricated in the LPS workshop by Ismaël Nimaga. This project has required 6 years of tests, from the development of various test models to the final flight model. It was made through a collaboration with the IAS (Institut d’ Astrophysique Spatiale), in the context of the programme for pooling CNC tools. The success of this project shows the know-how of our workshop. To date, they are the most complex parts made on the CNC milling machine at the LPS.

The SYMBIO-SYS instrument
SIMBIO-SYS will map various surface properties of Mercury (geology, composition, topography…). It contains three instruments :

  • HRIC, a High Spatial Resolution Imaging Channel that will characterize at high spatial sampling (down to 5 meters) the geology of the surface.
  • STC (STereo Channel), a stereoscopic imaging channel that will map the whole planet in relief at a 50 m / pixel.
  • VIHI, a Visible Infrared Hyperspectral Imager that will obtain images of the planet in more than 250 spectral wavelengths. This spectral information will be used to identify the composition of the surface.
