Engineering concepts for Space Aeronomy explained Space qualification of satellite instrument componentsTo take a product, process, or material and test it in order to prove that it will withstand the environment of space flight. DOAS method used for measurement of atmospheric gasesFor most measurements of atmospheric ingredients, the same technique is used: the DOAS method. 3D printers build complex objects layer by layerA 3D printer builds a three-dimensional object from a Computer-Aided Design (CAD) model, usually by successively adding material layer by layer, which is why it is also called additive manufacturing. Printed circuit board (PCB) in computers and electronic devicesBoard with with circuits that connect electronic components together. Used in computers and other electronic devices. Electromagnetic compatibility, for correct operation of equipmentThe ability of electrical equipment and systems to function acceptably in their electromagnetic environment, by limiting unintentional electromagnetic energy. Acousto-Optical Tunable Filter (AOTF), what is it exactly?A filter that selects different optical wavelengths in an incoming light beam by applying a radio-frequency signal. Surface mounting in computers and electronic devicesMethod in which electrical components are mounted directly onto the surface of a printed circuit board (PCB). Historical missions: 4 space instruments aboard the ExoMars Trace Gas OrbiterThe science payload of ExoMars TGO consists of four instruments measuring atmospheric gases on Mars. Atlas-1, atmosphere lab on board of space shuttle Atlantis1992 mission with experiments for understanding the interaction between the sun and the Earth's atmosphere. Belgian astronaut Dirk Frimout flew along. Dirk Frimout, from atmospheric scientist to first Belgian astronautHis professional life in space science reached a "high point" during the space mission Atlas-1.
