Welcome to the Mars Exploration Rovers Portal to Observations, Resources, and Tools to Advance Legacy Science (MER PORTAL)!

What would you like to do?

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 and contextual information
  • Visualization and time conversion tools
  • An intuitive science-based search with the capability of downloading selected data from the PDS

Developing this PORTAL is a huge undertaking. We’re currently working on Phase I of the project (2022-2026). By the end of 2026, the PORTAL should have:

  • Instrument Descriptions, aimed at graduate students and upper-level undergrads
  • Data Analysis User Guides, aimed at experienced researchers who are new to MER data analysis
  • The Guide to Mars through the eyes of Spirit and Opportunity, to teach everyone how to identify geologic and atmospheric phenomena in MER images
  • Undergraduate-level lesson plans based on the Guide to Mars through the eyes of Spirit and Opportunity
  • Links to existing tools and websites relevant to the MER mission and scientific analysis

We’re also doing the behind-the-scenes development necessary for our science-based data search function, which we’re hoping to produce in Phase 2 of the project.
