Mercury Transfer Module separation confirmed! 📡 ✅
Signal acquired via our Cebreros deep-space antenna confirms the spacecraft is healthy and operating as expected.
The MPO and Mio spacecrafts are now on their way to Mercury orbit insertion on 21 November.
Farewell, MTM. Mercury awaits. ☀️🛰️

The #BepiColombo MTM separation sequence has now started on-board, taking care of all that is needed for separation to take place. 🛰️
We'll only see this on ground about 11 min later. ⏱️
Mission teams are closely tracking system status ahead of this key milestone. 📈

BepiColombo has switched off its solar electric propulsion as the trio Bepi, Mio and MTM draw closer to Mercury.
Meanwhile, on the ground, teams across ESA, JAXA and industry are rehearsing the next critical step for these space adventurers: arriving at Mercury.
