Prin urmare, oamenii de \u0219tiin\u021b\u0103 au decis s\u0103 exploreze subsolul mar\u021bian! Pentru a face acest lucru, au folosit instrumentul MARSIS de la Mars Express, un radar mar\u021bian avansat care permite sondarea subsolului \u0219i a ionosferei Planetei Ro\u0219ii. MARSIS este un \u00abradar de penetrare a solului\u00bb, ceea ce \u00eenseamn\u0103 c\u0103 poate transmite impulsuri radar din orbit\u0103 c\u0103tre suprafa\u021ba lui Marte.

Este destul de ingenios!<\/p>\n<p>Un studiu bazat pe datele colectate de MARSIS a permis realizarea unei descoperiri a\u0219teptate de mult\u0103 vreme. Calota polar\u0103 sudic\u0103 a planetei Marte cuprinde numeroase straturi de ghea\u021b\u0103 \u0219i praf, cu o ad\u00e2ncime de 1,5 km, pe o zon\u0103 de aproximativ 200 km lungime. O reflexie radar deosebit de str\u0103lucitoare, pe o distan\u021b\u0103 de aproximativ 20 km, a atras aten\u021bia oamenilor de \u0219tiin\u021b\u0103 sub aceste straturi de depozite.
