Welcome to the Mars Exploration Rovers Portal to Observations, Resources, and Tools to Advance Legacy Science (MER PORTAL)! The goal of the MER PORTAL is to ensure that people who have no connection to the mission have what they need to analyze MER data: User Guides that enable data analysis, links to existing tools and websites relevant to the MER mission and scientific analysis, data quality indicators, contextual information, visualization and time conversion tools, and an intuitive science-based search with the capability of downloading selected data from the PDS.
