Gas management: Innovative solutions for separating Martian molecules and de-orbiting satellites

Our expertise has led us to take part in exploration projects and the search for life on planet Mars. Indeed, we worked on the Curiosity rover's gas phase chromatograph, as well as that of the ExoMars exploration robot, in order to separate the compounds found on Mars before analysis. We manufactured several of this device's components (helium tanks, valves, etc.), as well as assembling the chromatograph's capillary tubes with high-precision brazing.  

And that's not all. Our gas management expertise has allowed us to be involved in other projects. The law now requires defunct satellites to re-enter Earth's atmosphere to be disintegrated. For the Microscope satellite, which has been in space since 2016, we designed a system that ejects nitrogen gas to empty the satellite's tanks and inflate the IDEAS structure's two large masts, which accelerates Microscope's re-entry.

But before this, the innovative gas propulsion system guides the ultra-sensitive accelerometer on board the Microscope satellite, with the aim of explaining Newton’s law of universal gravitation.
