Mars Experienced Catastrophic Flooding 3.5 Billion Years Ago, Reshaping Planet's Surface
The new images highlight how dramatically different Mars' climate and geology were during its early history.

Why Mars Dried Up: Scientists Uncover The 'Missing Link' To Its Lost Oceans
A regional dust storm on Mars may have played a significant role in the planet's water loss, pushing water vapor high into the atmosphere.

Study Reveals Mars Has A Much Stronger Influence On Earth's Climate
Previous research on deep-sea sediments had suggested that Mars might influence Earth's climate, but the magnitude of this influence had not been clearly established.

European Space Agency Shares Details Of Martian Ice Age
The Martian ice age left behind striking features, revealing the planet's climatic past, ESA said.

AI-Assisted Study Finds No Evidence of Liquid Water in Mars’ Seasonal Dark Streaks
A large-scale AI analysis of more than two million Mars orbiter images shows that the planet’s dark slope streaks form through seasonal dust avalanches, not flowing briny water. The results settle a long-running debate, revealing that wind-driven dust activity shapes Mars’ surface and offering new insights into the planet’s climate past and e...

NASA’s ESCAPADE Mission Will Send Twin Probes to Uncover Mars’s Atmospheric Secrets
NASA’s ESCAPADE mission will launch twin mini-satellites, Blue and Gold, to Mars aboard Blue Origin’s New Glenn. The probes will study how solar wind stripped away Mars’s atmosphere and water, helping scientists understand the Red Planet’s lost climate and its transformation into the dry world we see today.

NASA’s Perseverance Rover Spots Megaripples, Proof Mars' Soil Is Still Shifting
NASA’s Perseverance rover has discovered striking megaripples — giant Martian sand waves — at a site called Kerrlaguna in Jezero Crater. These formations, about a meter tall, are larger than Earth’s beach ripples but smaller than the biggest dunes. Scientists say they formed when Mars had a thicker atmosphere and stronger winds, and many no...

ESA’s Mars Express Discovers Deep Valleys and Frozen Features Hinting at Mars’ Icy Past
In July 2025, the European Space Agency’s Mars Express orbiter captured a high-resolution image of Acheron Fossae, a region marked by deep chasms and ridges on Mars’s surface. These features, created by ancient crustal stretching, split the terrain into raised horsts and sunken grabens. Valley floors reveal smooth surfaces carved by slow-moving...

New Study Reveals Mars Faced Heavy Rains: Possible Clue to Ancient Life
The revelation that Mars once had Earth-like rainfall reshapes our understanding of planetary evolution. The insights support the theory that early Mars was far more hospitable than previously believed, possibly housing primitive life forms. The findings could guide future missions like NASA’s Perseverance in locating signs of fossilised organism...

Trump NASA Budget Prioritises Moon, Mars Missions Over Research
Donald Trump's proposed NASA budget released puts crewed missions to the Moon and Mars front and center -- slashing science and climate programs.

Water on Ancient Mars? New Study Challenges the Cold Planet Theory
Scientists have uncovered compelling evidence suggesting that early Mars was surprisingly wet, featuring extensive networks of lakes and river basins shaped by rainfall and snowfall. This challenges long-held views of a predominantly cold and icy ancient Mars. Despite current climate models struggling to explain sustained liquid water on the Red Pl...

New Research Reveals Mars’ Red Colour Linked to Ancient Water Presence
A recent study suggests that Mars’ red hue originates from ferrihydrite, an iron oxide that forms in water-rich environments. Scientists recreated Martian dust in labs and found that the mineral remained stable despite the planet’s dry conditions. Data from orbiting spacecraft and rovers confirm this discovery, reshaping theories about Mars’ ...

Curiosity Rover Finds Evidence of Liquid Water on Mars, Expanding Habitability Timeline
Reports from NASA’s Curiosity rover reveal evidence of ancient liquid water on Mars, challenging previous models. Images from Gale Crater show wave-like ripples, similar to Earth’s lakebeds. Scientists suggest the findings indicate Mars once had a denser atmosphere, which allowed liquid water to exist longer than previously believed. This disco...

Curiosity Rover Observes Iridescent Clouds on Mars, Offering New Insights
NASA’s Curiosity rover has captured rare iridescent clouds drifting across the Martian sky, observed at high altitudes in twilight conditions. These carbon dioxide ice clouds were seen forming between 60 and 80 kilometres above the surface before evaporating as they descended. Scientists believe their presence hints at unknown cooling mechanisms ...

New Research Suggests Mars Experienced Warm and Cold Periods Affecting Liquid Water
New research from Harvard University suggests that Mars experienced alternating warm and cold periods billions of years ago, affecting its climate and ability to sustain liquid water. These fluctuations, which lasted up to 100,000 years, may have influenced the planet’s potential for life. The study highlights the role of hydrogen in trapping hea...
