The Exosat mission was approved in 1973, when the intention was to take very simple readings of X-ray sources-at that time a relavively small number of positions were known. Designed to observe and detect high-energy sources, Exosat was the first ESA mission to study the Universe at X-ray wavelengths, and one of the first unmanned satellites to feature an on-board computer. 1, record 1, English, - Exosat%20mission

The extraction system consists of 3 grids: the plasma grid on high positive voltage (60 kV, 93 kV or 100 kV, respectively), the decel grid on low negative voltage (-1.5 kV), and the grounded grid. The decel voltage is generated by autobiasing, i.e. by the extracted current and prevents secondary electrons generated in the grid system entering the plasma source. 2, record 2, English, - plasma%20grid
