NASA's twin rover project, consisting of the Spirit and Opportunity rovers, had two primary goals: to search for evidence of past water activity on Mars and to assess the planet's geological history. These objectives aimed to determine if Mars had conditions suitable for microbial life in its past. Additionally, the rovers were tasked with analyzing the Martian surface and atmosphere to further our understanding of the planet's environment.
