![]() ![]() The search for evidence of habitability, taphonomy (related to fossils), and organic compounds on Mars is now a primary objective for space agencies. įollowing the confirmation of the past existence of surface liquid water, the Curiosity, Perseverance and Opportunity rovers started searching for evidence of past life, including a past biosphere based on autotrophic, chemotrophic, or chemolithoautotrophic microorganisms, as well as ancient water, including fluvio-lacustrine environments ( plains related to ancient rivers or lakes) that may have been habitable. At least two-thirds of Mars's surface is more than 3.5 billion years old, and it could have been habitable since 4.48 billions of years ago, 500 million years before the earliest known Earth lifeforms Mars may thus hold the best record of the prebiotic conditions leading to life, even if life does not or has never existed there. This is especially true since Mars has a cold climate and lacks plate tectonics or continental drift, so it has remained almost unchanged since the end of the Hesperian period. Mars is of particular interest for the study of the origins of life because of its similarity to the early Earth. Scientific searches for evidence of life began in the 19th century and continue today via telescopic investigations and deployed probes, searching for water, chemical biosignatures in the soil and rocks at the planet's surface, and biomarker gases in the atmosphere. Cumulative evidence suggests that during the ancient Noachian time period, the surface environment of Mars had liquid water and may have been habitable for microorganisms, but habitable conditions do not necessarily indicate life. To date, no proof of past or present life has been found on Mars.
