ExoMars is the Mars exploration programme established by the  European Space Agency in partnership with the Russian Federal Space Agency

The  primary  goal  of  the  ExoMars  programme  is  to  address the question of whether life has ever existed on Mars.  The  programme  comprises  two  missions:  the  first  one,  launched  in  March  2016,  consists  of  the  Trace Gas  Orbiter  (TGO)  and  Schiaparelli,  an  entry,  descent  and  landing  demonstrator  module  (EDM).  The second  is  planned  for  launch  in  2020  and  comprises  a  rover  and  surface  science  platform.

Deimos  has been participating in the project since 2004, playing a pivotal role in both Phase E (operational phase) of the first mission and Phase C (detailed design and implementation phase) of the second mission. Within the framework of the ExoMars programme Elecnor Deimos has been chiefly involved in the end-to-end mission design and analysis. This comprises the optimum design of the trajectory from launch to landing  on  Mars,  including  events  such  as  the  interplanetary  transfer,  the  separation  of  the  TGO  and EDM  and  the  landing  on  a  prescribed  area  of  the  surface  of  Mars.

End-to-end mission analysis and design: from launch to landing on Mars

During  the  interplanetary  transfer phase, Elecnor Deimos was involved in the design and analysis of the flight and navigation architecture. The company was also responsible for the design and analysis of features of the EDM from its separation from the TGO to the surface of Mars.  Deimos will also play a key role in the next ExoMars mission, for which it is responsible for verifying the design  and  features  of  the  atmospheric  phase  and  independent  verification  of  the  algorithms  of  the GNC/AOCS subsystem. Deimos’ involvement throughout the ExoMars programme extends the range of applications for flight technologies essential for future exploration missions such as a return mission to Mars.
