it home reported on september 3rd that according to a report by japan's kyodo news, the european space agency and the japan aerospace exploration agency announced yesterday that the time for the probe of the eu-japan joint mercury exploration project "bepicolombo" to enter orbit around mercury will be delayed.

due to problems with the propulsion module (mtm) power supply system, it was unable to start the electric propulsion engine at maximum output, and the orbital entry time was postponed from the originally planned december 2025 to november 2026.

in 2018, the bepicolombo mercury probe jointly developed by the european space agency and the japan aerospace exploration agency was successfully launched. it was expected to reach mercury in 2025 and will help people understand the structural and magnetic field characteristics of mercury.

in 2021, bepicolombo sent back the first image of the surface of mercury. because mercury is too close to the sun, it is difficult to survey, so our current knowledge of mercury is quite limited.

it home note: mercury is the smallest and closest planet to the sun in the solar system. it was called chenxing in ancient china. its aphelion is 69,817,900 kilometers, perihelion is 46,001,200 kilometers, semi-major axis is 57,909,100 kilometers, and its orbital period is 87.9691 days.
