mars’ Jezero Crater: Ancient Volcano Hints at Past Life?
Pasadena, CA – Could the Jezero Crater on Mars have once harbored life? New findings suggest the presence of a lake, a volcano, and the essential components for life over three billion years ago. Analysis from the Rover Perseverance and orbital probes indicates that Jezero Mons, a mountain bordering the crater, is likely an ancient stratovolcano, igniting further interest in the search for Martian biosignatures.
Perseverance Rover Uncovers Clues in Jezero Crater
Since its arrival in March 2021, the Rover Perseverance has been meticulously exploring the Jezero Crater to unravel the red planet’s history and identify potential signs of ancient Martian life. The crater was strategically chosen due to prior studies indicating that this vast basin,formed by a meteor impact approximately 3.7 billion years ago, once held a lake fed by a river.
Perseverance swiftly confirmed the hydrological history of the Jezero Crater, notably through the examination of deltaic sedimentary formations. These findings strongly suggest that life could have potentially thrived in this ancient lake, even though definitive proof remains elusive.
The Mystery of Jezero Mons: An Ancient Volcano
A new discovery is bolstering scientists’ hopes regarding the Jezero Crater’s potential to have once hosted rudimentary Martian life. Researchers have determined that the small mountain bordering the crater is, actually, an ancient volcano. This revelation opens exciting new perspectives on the habitability of Mars over three billion years ago.
This Mont first caught scientists’ attention in 2007. However, it wasn’t until Perseverance landed in 2021 that the hypothesis of it being an ancient volcano gained traction, thanks to data analysis from probes such as Mars Odyssey Orbiter, Mars Reconnaissance Orbiter, and Exomars Trace Gas Orbiter.
Comparing jezero Mons to Other Volcanoes
Researchers compared Jezero Mons’s characteristics to those of other identified Martian volcanoes and terrestrial volcanoes. Data collected by the Rover Perseverance revealed that certain rocks at the bottom of the crater were of volcanic origin, though the source of this volcanism was initially unclear.
Did You Know? Stratovolcanoes are known for their layered structure, formed by successive eruptions of lava and ash. this type of volcano is common on Earth and now potentially identified on Mars.

The Search for Life Beyond Earth: why Mars?
Mars has long been a focal point in the search for extraterrestrial life due to several factors. Its proximity to Earth, geological history, and the presence of water ice make it a promising candidate. The discovery of potential biosignatures in Jezero Crater further intensifies this interest.
Implications for Future Mars Missions
The ongoing exploration of Mars, including sample return missions, is crucial for understanding the planet’s past and assessing the possibility of past or present life. future missions may focus on drilling deeper into Martian soil and analyzing samples with advanced technology to detect definitive biosignatures.
