This Astrobiology journal article proposes that life- closely related the halophiles of Earth- might exist on Mars. It introduces extreme environments on Earth, supports the evidence for water on Mars, and analyzes current halophile research. Based on recent findings, the author speculates that even if present-day life is not present on Mars ancient bacteria preserved in salt deposits could be retrieved from an era when the climate of Mars was more conducive to life.
