In a groundbreaking discovery, scientists have uncovered evidence that liquid water flowed on Mars as recently as 742 million years ago—a mere blink in geological time. The revelation comes from a Martian meteor revocationite that crash-landed on Earth, which had been quietly stored in a drawer at Purdue University until researchers recognized its cosmic significance. This unassuming rock has now rewritten our understanding of the Red Planet’s history, suggesting Mars was far from the barren, dusty wasteland we see today.
The meteorite, analyzed by a team of planetary scientists, contains mineral signatures indicating it interacted with flowing water millions of years ago. Researchers believe this water may have originated from underground ice reserves, potentially melted by volcanic activity beneath the Martian surface. Such conditions could have created habitable environments, raising tantalizing questions about the planet’s past potential to support life.

“Mars wasn’t always the dry desert we picture,” said Dr. Emily Carter, a lead researcher on the study. “This discovery shows liquid water persisted much later than we previously thought, transforming our view of the planet’s geological and possibly biological history.”
While the findings don’t confirm extraterrestrial life—aliens remain firmly in the “to be determined” category—the presence of water suggests Mars once had the right conditions to host microbial organisms. The study, published in the journal Planetary Science Advances, has sparked renewed excitement in the scientific community, with experts calling the meteorite a “cosmic treasure” that unlocks new clues about Mars’ wetter, more dynamic past.
As NASA and other space agencies plan future missions to explore the Red Planet, this discovery underscores the importance of searching for signs of ancient water—and perhaps life—beneath Mars’ surface. For now, the meteorite stands as a testament to a time when Mars was vibrant, wet, and full of possibility.
Key Points:
- Recent Discovery: Scientists confirmed liquid water flowed on Mars 742 million years ago, a relatively recent event in geological terms.
- Martian Meteorite: Evidence comes from a meteorite that landed on Earth, stored at Purdue University until its significance was recognized.
- Water Source: Water likely originated from underground ice melted by volcanic heat, indicating dynamic geological activity.
- Mars’ Past: Findings suggest Mars was not always a dry, barren planet but had conditions potentially suitable for life.
- No Alien Confirmation: While the discovery fuels speculation about life, no evidence of extraterrestrial organisms has been found.
- Scientific Impact: Published in Planetary Science Advances, the study reshapes understanding of Mars’ history and guides future exploration.
