What do you study? http://rockettube.fun/ rokettube  Some of the layers near the base of Mount Sharpe show evidence of hydrated minerals, suggesting that there was some aqueous process in the Gale Crater. Maybe there was a lake, but how big was it and how much water was in it? It's not clear yet, but looking at the minerology, you start to unravel the history of Mars.
