His professional life in space science reached a "high point" during the space mission Atlas-1.

1992 mission with experiments for understanding the interaction between the sun and the Earth's atmosphere. Belgian astronaut Dirk Frimout flew along.
For most measurements of atmospheric ingredients, the same technique is used: the DOAS method.

The science payload of ExoMars TGO consists of four instruments measuring atmospheric gases on Mars.

To take a product, process, or material and test it in order to prove that it will withstand the environment of space flight.
Board with circuits that connect electronic components together. Used in computers and other electronic devices.

Electro-Magnetic Compatibility is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment.

A filter that selects different optical wavelengths in an incoming light beam by applying a radio-frequency signal.

Surface-Mount Technology (SMT) is a method in which the electrical components are mounted directly onto the surface of a Printed Circuit Board (PCB).
A 3D printing process builds a three-dimensional object from a Computer-Aided Design (CAD) model, by successively adding material layer by layer.

For the design, the manufacturing and the usage of atmosphere measuring devices one needs electronics, mechanics, software, computing and technical skills.
