Welcome to the LPI Early Mars topical website. 


The influx of new data received from recent spacecraft missions to Mars, the study of the SNC meteorites, recent progress in early climate modeling, the growing evidence of the role of water in the planet's evolution, and the rapid pace of new discoveries about the origin and diversity of life on Earth have reinvigorated interest in both the conditions that prevailed on Mars during its first billion years of geologic history and their implications for the development of life.


These issues were addressed at the First International Conference on Early Mars, which was held in Houston, Texas, in April 1997; at the Second Conference, which was held in Jackson Hole, Wyoming, in October 2004; and, finally, at the Third Conference, that was held at Lake Tahoe, Nevada in May 2012.


The purpose of this website is to provide one-stop access to news about the latest Early Mars research; the 1st-3rd International Conferences on Early Mars (and related meetings), including programs, abstracts, conference summaries, key questions, field trip guides, photos, journal special issues, and announcements of future meetings; educational resources and student research opportunities; a searchable database of Early Mars peer-reviewed publications; and a variety of other web-based resources.
