Was There Ever Life on Mars? New Evidence Points Closer Than We Think
Poinews.com – Was there ever life on Mars? For decades, the Red Planet has been viewed as a harsh, barren world seemingly unfit for living organisms — despite being the celestial body in our solar system most similar to Earth. However, groundbreaking new research, supported by the latest findings from NASA’s Perseverance rover, suggests that Mars may once have harbored conditions suitable for life. This remains one of the most compelling open questions in modern astronomy and was a central topic at COSPAR, the world’s premier space research conference organized by Italy’s National Institute for Astrophysics (INAF) and currently taking place in Florence.
“The combination of several lines of evidence, such as the discovery by NASA’s Perseverance rover of minerals that on Earth are produced by micro-organisms, and of complex organic matter, is increasing the likelihood that Mars may have been inhabited, at least in the past,” explained Teresa Fornaro, a researcher at the INAF Arcetri Observatory and professor of astrobiology in Florence who collaborates on the Perseverance mission.
Fornaro noted that any life on Mars would most likely have taken the form of micro-organisms living underground, shielded from the intense radiation bombarding the planet’s surface and drawing energy directly from the rocks themselves. “So far, we’ve only gathered indirect evidence,” she added. The organic matter discovered so far has a heavily altered structure, making it difficult to trace back to its original source. “We’ll only have a definitive answer once we can analyse the samples here on Earth,” she continued, emphasizing why results from upcoming missions to the Red Planet could prove especially significant.
ExoMars: The Next Frontier in Martian Exploration
Chief among these upcoming missions, according to Fornaro, is ExoMars, run by the European Space Agency (ESA), with its Rosalind Franklin rover taking centre stage. Launch is scheduled for 2028, with touchdown on the Martian surface expected in 2030. The mission is already under way: an initial probe, the Trace Gas Orbiter, was sent in 2016 to study the Martian atmosphere and search for trace gases that could indicate biological activity.
The rover itself will follow in 2028, aiming to gather direct evidence to answer one central question — has life ever existed on Mars? “Until now, rovers have only been able to explore the surface. Rosalind Franklin will be able to drill up to two metres into the ground, carrying the most advanced instruments ever sent to Mars,” Fornaro said, highlighting the mission’s innovative scope and potential to revolutionize our understanding of the Red Planet.
Meanwhile, NASA’s Perseverance rover, which began exploring the Martian surface in 2021 in search of traces of ancient organic life, is still active on the planet. The Mars 2020 mission was originally designed to last one Martian year — around 687 Earth days — but has been extended indefinitely. The rover remains fully operational and its ongoing collection of rock and regolith samples continues to drive major advances in space research.
A sample collected in the summer of 2024 — the same one referenced by Fornaro — contained potential biological traces. Though these still require further analysis to confirm, NASA administrator Sean Duffy described the find as “the moment when we have come closer than ever to life on Mars.” This discovery has reignited scientific enthusiasm and underscored the importance of sample return missions.
Frequently Asked Questions About Life on Mars
What is the strongest evidence for past life on Mars? The discovery of minerals on Earth that are produced by micro-organisms, along with complex organic matter found by the Perseverance rover, represents the strongest current evidence.
When will we know for sure if life existed on Mars? Scientists expect a definitive answer once samples collected by Perseverance and future missions are returned to Earth for detailed laboratory analysis, potentially within the next decade.
What makes the Rosalind Franklin rover special? Unlike previous rovers that only explored the surface, Rosalind Franklin will drill up to two metres underground, accessing protected environments where microbial life may have survived.
