Russian instrument on Board the “Bepicolombo” registered gamma radiation from the Earth

Scientific instruments and PHEBUS MGNS developed with the participation ofn scientists and installed on European-Japanese interplanetary station “Bepicolombo”, successfully held a monitoring geocoronal Land and registered gamma radiation from our planet during a gravity assist. It was necessary to calibrate the devices, which will continue to explore the mercury, reported on the website IKI.

Start the “Bepicolombo” was held on 20 October 2018, when the space went two scientific orbital probe: the European MPO (Mercury Planetary Orbiter) and the Japanese MMO (Mercury Magnetospheric Orbiter) and a migrating module, which will deliver the probes to mercury. Arrival to the nearest to the Sun planet is scheduled for December 2025, after which the probes will be released on different polar orbit and begin the scientific program, designed for at least a year.

10 April 2020″, and Bepicolombo” successfully made his first of nine (and only near Earth) gravity-assist maneuver, flying at a minimum distance of 12,700 kilometers from the planet. It is possible to reduce his speed about five kilometers per second and transferred the station to a lower heliocentric orbit is not wasting fuel driving along this orbit, the spacecraft will reach Venus and then to mercury.

During the maneuver the camera and most of the scientific instruments on Board the probes were enabled and collected data, which are then used for their calibration.n gamma and neutron spectrometer MGNS, which is designed to search for deposits of water ice and studies of the chemical composition of the surface of mercury, was able to register gamma radiation from the Ground. “Failure” in the data indicates a temporary disconnection of sensors during the reversal station, the shallow peak corresponds to the moment of closest approach to the planet, and the second, more acute burst of radiation speaks about the intersection of apparatus the radiation belts of the earth magnetosphere.
