On the spacecraft, sent to explore mercury, the first test devices

In mid-October 2019 started the mission BepiColombo, in which the spacecraft with research equipment on Board went to mercury to study the planet. The launch was successful and the spacecraft sent the first pictures shot during the flight what we reported earlier. And recently, last check of the instruments of the ship. This became known details about the hardware that carries a research space ship.

Recall that the composition of the BepiColombo includes a research module 3: transport module the MTM (Mercury Transfer Module), responsible for the delivery of two Mercury Planetary Orbiter (MPO) and Mercury Magnetospheric Orbiter (MMO), which will study the planet’s surface and its magnetosphere. The mission is to study composition of the planet is supposed to start in 2025, when the probe is expected to reach the first planet in our Solar system.

As for research equipment, which is installed on Board, it was reported that this 2 instrument PHEBUS and MSASI. PHEBUS (the joint project of France, Italy, Japan and Russia) is an ultraviolet spectrometer to study the composition and ecosphere planet. The wavelength range of the device is 50-330 nm and thus it can detect the presence of hydrogen, oxygen, potassium, calcium, helium, xenon and argon. MSASI (created by Russian and Japanese engineers) is necessary to obtain data on the distribution of sodium atoms in space and their temperature.

For the first time the device was tested on October 22. Then they turned for 25 minutes and unblocked the guidance system PHEBUS, and 3 Dec have already been tested and the system restore PHEBUS, and also open the camera cover one of the sensors operating in the extreme ultraviolet range. It is worth noting that during the interplanetary flight, all devices protected by a heat screen MOSIF, so interoperability is quite limited, but available data indicate that all devices are working without any problems.
