The Structural and Thermal Models of the BepiColombo Mercury Planetary Orbiter and Mercury Transfer Module were mated for the first time on 11 April 2012. The mating was performed to accurately position the inter-module hardware on the transfer module.
The protoflight models of the two Basic Angle Monitor (BAM) Opto-Mechanical Assembly (OMA) bars have been delivered to the spacecraft Prime Contractor and are being prepared for integration into the Payload Module (PM).
