RUAG technology going to Mars

The European Mars satellite ExoMars Trace Gas Orbiter is ready for launch. On 14 March, the satellite will begin its roughly seven-month journey to the Red Planet from the Russian cosmodrome in Baikonur. Products built by RUAG Space are on board.
ExoMars is a joint programme by the European Space Agency (ESA) and the Russian space agency Roscosmos to explore Mars and its environment. The main goal is to investigate whether life has ever existed on the Red Planet - and even whether it might still exist. The ExoMars programme is divided into two parts. The first mission consists of a Mars orbiter - the Trace Gas Orbiter (TGO) - and a landing module called Schiaparelli. The second mission, which is scheduled to launch in 2018, will place a European Mars rover and a fixed Russian platform on Mars. The space technology company Thales Alenia Space is the prime contractor for this first mission.

In Switzerland, RUAG Space developed and manufactured the swivelling telescope for Cassis, a high-resolution camera that the orbiter will use to produce exact images of the Red Planet's surface on the search for methane sources and a suitable landing place for the future Mars rover.

During its six-year mission, the Mars orbiter will be shielded by a protective covering. The thermal insulation comprises several layers of very thin metallised plastic film and is designed by RUAG Space to meet the specific insulation requirements and individually adapted to fit the satellite's complex surface shape. In order to radiate off the heat generated by the scientific instruments, individual surface sections are covered with optical solar reflectors (OSRs) mounted on panels by RUAG Space.

The orbiter's central control computer, the slip rings for the pivoted solar panels also come from RUAG Space as does the separation mechanism for detaching the Schiaparelli landing module from the Mars orbiter.
