Mars InSight Lander, robotick\u00fd pr\u016fzkumn\u00edk vyslan\u00fd na Mars agenturou NASA, poskytl v\u011bdc\u016fm neoceniteln\u00e9 poznatky o vnit\u0159n\u00ed struktu\u0159e planety. Jeho mise spo\u010d\u00edv\u00e1 ve studiu k\u016fry, pl\u00e1\u0161t\u011b a j\u00e1dra Marsu, zn\u00e1m\u00fdch jako jeho \u201evnit\u0159n\u00ed prostor\u201c.<\/p>\n\n
Seismick\u00e1 data InSight odhalila, \u017ee k\u016fra Marsu m\u00e1 t\u0159i odli\u0161n\u00e9 vrstvy. Tento objev p\u0159edstavuje prvn\u00ed p\u0159\u00edpad, kdy v\u011bdci nahl\u00e9dli dovnit\u0159 jin\u00e9 planety ne\u017e Zem\u011b. T\u00fdm pou\u017eil seismometry k detekci vibrac\u00ed, kter\u00e9 se \u0161\u00ed\u0159ily k\u016frou, co\u017e jim umo\u017enilo ur\u010dit tlou\u0161\u0165ku a slo\u017een\u00ed ka\u017ed\u00e9 vrstvy.<\/p>\n\n
Odhaduje se, \u017ee k\u016fra je siln\u00e1 mezi 12,4 a 23 m\u00edlemi, co\u017e je v\u00fdrazn\u011b m\u00e9n\u011b ne\u017e k\u016fra Zem\u011b, kter\u00e1 m\u016f\u017ee dos\u00e1hnout tlou\u0161\u0165ky a\u017e 25 mil.

V\u011bdci se naopak domn\u00edvaj\u00ed, \u017ee Mars m\u016f\u017ee recyklovat star\u0161\u00ed k\u016frov\u00fd materi\u00e1l, m\u00edsto toho, aby hromadil nov\u00e9 vrstvy na vrcholu. Tento proces by mohl b\u00fdt poh\u00e1n\u011bn vulkanickou aktivitou, proto\u017ee Mars byl kdysi pokryt sopkami, kter\u00e9 umo\u017enily magmatu dos\u00e1hnout povrchu.<\/p>\n\n
InSight tak\u00e9 detekoval t\u00e9m\u011b\u0159 500 mal\u00fdch \u201emarsot\u0159es\u016f\u201c, ale pouze n\u011bkolik s magnitudou v\u011bt\u0161\u00ed ne\u017e 4,5. V\u011bt\u0161\u00ed ot\u0159esy by vyvolaly hlub\u0161\u00ed dun\u011bn\u00ed, kter\u00e9 by mohlo pomoci ur\u010dit jejich p\u016fvod v j\u00e1dru a pl\u00e1\u0161ti Marsu. Nedostatek velk\u00fdch marsot\u0159es\u016f v\u0161ak zt\u011b\u017euje detailn\u00ed studium t\u011bchto hlub\u0161\u00edch vrstev.<\/p>\n\n

V\u011bdci se domn\u00edvaj\u00ed, \u017ee vnit\u0159n\u00ed teplo Marsu mohlo b\u00fdt nedostate\u010dn\u00e9 k vyvol\u00e1n\u00ed dostate\u010dn\u00e9 vulkanick\u00e9 aktivity pro vytvo\u0159en\u00ed siln\u00e9 k\u016fry. M\u00edsto toho mohla planeta recyklovat sv\u016fj k\u016frov\u00fd materi\u00e1l, co\u017e vedlo k jej\u00ed sou\u010dasn\u00e9 tenk\u00e9 a vrstven\u00e9 struktu\u0159e.<\/p>\n\n
