The European Space Agency and JAXA held an online press briefing on August 31, 2026, to discuss the latest developments of the BepiColombo mission. [^2]

The separation of the Mercury Transfer Module marks the start of BepiColombo's Mercury arrival phase. [^3]

For the first time, a mission will place two orbiters, Europe's MPO and Japan's Mio, simultaneously into different orbits around Mercury, with Mio studying the magnetosphere and charged particles from a distant orbit and MPO studying the surface and interior from close range. [^4]

The BepiColombo mission schedule includes 16 braking maneuvers beginning 2026-11-21, separation of the Mio orbiter on 2026-12-09, MPO reaching its final orbit in March 2027, and scientific exploration starting in April 2027. [^5]

Mercury orbit insertion is scheduled to take place in November 2026. [^6]

Austria's participation in BepiColombo, involving planning and the company Terma Technologies, spans over 20 years, with €36 million in industrial participation and €2.5 million for scientific instrument development, making it Austria's most financially extensive participation in an ESA mission.
