The first mission of the ExoMars programme, scheduled to arrive at Mars in October 2016, consists of a Trace Gas Orbiter (TGO) plus an Entry, Descent and Landing Demonstrator Module (EDM) named Schiaparelli. The Orbiter and Schiaparelli were launched on 14th March 2016 on a Proton rocket. The main scientific objectives of this mission are to search for evidence of methane and other trace atmospheric gases that could be signatures of active biological or geological processes and to test key technologies in preparation for ESA's contribution to subsequent missions to Mars. Another important objective is the demonstration of a successful Entry, Descent and Landing on Mars. Gathering scientific data during these flight phases is a further key element and would provide very important data for future missions. This data could for example be used for an optimization of the heat shield, as the design of the back cover heat shield was carried out with relatively high safety margins. This is due to the fact that the prediction of the aerothermal and radiative loads on the back cover, using existing experimental and numerical tools, still has big uncertainties. In order to close this gap, DLR developed the EDM back cover instrumentation package COMARS+ consisting of three combined aerothermal sensors, one broadband radiometer sensor and an electronic box. The aerothermal sensors combine four discrete sensors measuring static pressure, total heat flux, temperature and radiative heat flux at two specific spectral bands. The infrared radiation in a broadband spectral range is measured by the separate broadband radiometer sensor. The electrical interface between sensors and EDM data handling system is provided by the payload electronic box. After passing extensive qualification and acceptance test campaigns including strict bioburden and planetary protection requirements the COMARS+ payload is now on its way to Mars on-board the ExoMars Schiaparelli capsule.
