ocr: O Or VIKING 1AND2 At telescopic shovel makes it possible to collect LANDER EQUIPEMENTO samples of the Martian soil. Samples are introduced into funnels for tests by various detection devices: The X-Ray Florescence Spectrometer (XRFS) determines the composition of the Martian soil by irradiating a soil sample with iron-55. and cacimium-109. The X-rays produced are then analyzed. This device weighs less than two kilos and has an average energy consumption of 3.5 watts. The Gas Chromatograph. Mass Spectrometer (GCMS) which studies the structure of large molecules. The sample is placed in an oven ...
