Usawoti we-sulfate utholakale emadwaleni e-sedimentary akhiwe phakathi kuka-3,3 no-3,7 weminyaka eyizigidigidi edlule. Ilukuluku lahlaziya amanye amadwala amadala ku-Mars futhi alitholanga nelilodwa kulawa kasawoti.
Abacwaningi bakholelwa ukuthi usawoti we-sulfate uwubufakazi bokuhwamuka kwechibi le-crater endaweni eyomile ye-Red Planet, futhi bakholelwa ukuthi izinsalela ezakheka kamuva zinganikeza ukukhanya okwengeziwe kokuthi i-Martian surface yaqedwa kanjani esikhathini esizayo.
