ExoMars RSI


The 2020 ExoMars Mission is a broad cooperative programme between the European Space Agency (ESA) and the Russian Roscosmos State Enterprse (ROS). The ExoMars mission will deliver a European rover and a Russian surface platform to the surface of Mars. The ExoMars Rover will travel across the Martian surface during its planned 6-month life in search for signs of life. It will collect samples from within surface rocks and from underground to a depth of 2 meters using a drill, and analyse them with next-generation instruments. ExoMars mission will be the first mission to combine the capability to move across the surface and to study Mars at depth, which makes it unique. As software is hard to trust, and with high costs at stake, the Rover cannot be left without any backup. A need to have a mean to keep the mission alive even in case when the software nominally running on the Rover fails has opened the door to SSF as a known provider of highly critical software: The Recovery Software Image (known as RSI) is the ultimate back up software which provides basic functionality to the ground to investigate and maintain the Rover Software. The RSI cannot be “fixed” after launch, yet it has to provide such recover functionality for the Rover Software with greatest reliance. And now, after customer test campaign has been confirmed completed with no RSI problems reported, SSF is proud to declare the project successful. Even though there have been many challenges along the way, they are also great lessons learned for future missions to come and will be gratefully remembered when eventually Rover starts living its life – short for a human – but big and significant for humanity. SSF is happy to be part of this adventure.
