ESA - Robotic Exploration of Mars - ExoMars 2016 Trace Gas Orbiter core module during integration at Thales Alenia Space, Cannes

Pictured here is the ExoMars 2016 Trace Gas Orbiter (TGO) core module during integration of its electrical subsystems at Thales Alenia Space, Cannes, France in November 2014. The central cylinder is the core of the mechanical structure; one of its functions is to transmit the forces and stresses experienced during launch evenly throughout the rest of the spacecraft. The cylinder extends to the top of the core module, where the Schiaparelli entry, descent and landing demonstrator module (also known as the EDM) – the other major element of the ExoMars 2016 mission – will be mounted during launch and transfer to Mars.
