Press release BepiColombo

Mar. 10th, 2020 - Mar. 10th, 2020

On 10 March 2020 ESA / JAXA BepiColombo ( and took advantage of Earth's gravitational field and sped up its journey towards Mercury, its destination. The BepiColombo consists of three modules: the Mercury Transfer Module (MTM), the Mercury Planetary Orbiter (MPO) engineered in ESA, and the JAXA Mercury Magnetospheric Orbiter (MMO). One of several experimental MPO modules is Mercury Gamma-Ray and Neutron Spectrometer (MGNS) ( The main task of MGNS is to determine the elemental composition of the interesting areas of Mercury's surface. The main component of MGNS is Gamma-Ray Spectrometer based on LaBr3 crystal. This spectrometer was tested and calibrated by IEAP CTU in Prague ( within the ESA ESTEC project 4000103891/11 / NL / CBi. Portable Calibration Gamma-Ray Station (PCGRS) was developed for this project ( The PCGRS device is designed to calibrate gamma radiation detectors over a wide energy range. Calibration in a wide energyrange is very important, the characteristic radiation of the elements is distributed in the order of keV to MeV.
