ExoMars Trace Gas Orbiter prior to thermal tests
The ExoMars Trace Gas Orbiter (TGO) pictured prior to the start of thermal tests in the ESP500 Thermal Vacuum Chamber at the Thales Alenia Space premises in Cannes, France.
These tests measure the thermal performance of the spacecraft module under space conditions. In particular, they verify how the module behaves as the temperature changes in high vacuum (space-like) conditions, and how the module reaches thermal equilibrium.
