Mars May Have Had a Vast Ancient Ocean, Traced by Canyon Deltas

Researchers using data from ESA's ExoMars Trace Gas Orbiter, Mars Express, and NASA's Mars Reconnaissance Orbiter modeled a former sea level in Coprates Chasma (within Valles Marineris) and identified delta-like structures matching Earth river mouths, suggesting a large ancient Martian ocean at least as big as Earth's Arctic Ocean during a period of abundant surface water; this supports the idea of a once-habitable Mars, though implications for life remain uncertain.

Ancient Martian Ocean Spanned Half the Planet, New Imagery Hints

New high-resolution orbital imagery around Mars reveals delta-like structures near Valles Marineris that researchers say mark an ancient coastline, suggesting an ocean across the northern hemisphere that may have been as large as Earth's Arctic Ocean and existed about 3.37 billion years ago, supporting the idea of a historically “blue” Mars.

Ancient Shorelines Hint Mars Once Hosted a Global Ocean

New high-resolution imagery from Mars orbiters shows delta-like, fan-shaped deposits at the Coprates Chasma end of Valles Marineris, suggesting Mars once supported a vast, Earth-sized ocean in its northern hemisphere, implying long-lasting surface water and potentially connected water systems in the planet’s past.

Scientists Discover Potential New Mineral on Mars

Scientists have potentially discovered a new mineral on Mars, a ferric hydroxysulfate compound found near Valles Marineris, which may have formed through volcanic activity in the presence of oxygen and water at high temperatures. This discovery could provide insights into Mars' geological history and past water activity, and further research is needed to confirm its status as a new mineral on Earth.

"The Martian Mystery: Unraveling the Grand Canyon of Mars"

Valles Marineris on Mars, the grandest canyon in the Solar System, likely formed from a combination of processes including a giant impact that created Mars's moons, volcanic activity, and tectonic forces. The canyon, spanning 4000 kilometers across and up to 7 kilometers deep, was likely widened and deepened by erosion, landslides, and subsequent impacts. Mars's unique geological history, including the formation and destruction of a transient moon, contributed to the creation of this impressive feature, showcasing the planet's fascinating past and geological diversity.

"Jaw-Dropping Flyover of Mars' 'Labyrinth of Night' Takes You on an Epic Journey"

The European Space Agency has released a stunning video showcasing the vastness of Mars' Valles Marineris, the Red Planet's equivalent of Earth's Grand Canyon. The video provides breathtaking views of the canyon's Noctis Labyrinthus, a labyrinth of night spanning 740 miles. The footage was created using detailed stereo images taken by ESA's Mars Express orbiter and existing topographic data. The canyon's valleys measure up to 18.6 miles across and 3.7 miles deep, making it larger than the Grand Canyon. Scientists believe the canyon was formed by tectonic fractures and possibly influenced by water billions of years ago.

Mars Express unveils the enigmatic crinkly valley in stunning flyover video

The European Space Agency's Mars Express mission has released a flyover video showcasing Noctis Labyrinthus, a massive valley system on Mars that spans the length of Italy. The video reveals landslides, dune fields, and lowered regions of crust known as graben, indicating the planet's volcanic past. Mars Express has been operating since 2003 and, along with other spacecraft, continues to study Mars' weather and gather insights into its complex history. The thin atmosphere and high radiation on the surface make it challenging for organisms to survive, suggesting that life may exist underground.

Exploring Mars's Enigmatic Nighttime Maze with Mars Express

The European Space Agency's Mars Express has released a video showcasing a flight over the eastern part of Noctis Labyrinthus, a vast system of deep valleys on Mars. The video reveals distinctive features called "graben," which are parts of the crust that have subsided in relation to their surroundings. These formations were caused by intense volcanism in the nearby Tharsis region. The video also highlights intersecting canyons, valleys, landslides, and dune fields, providing a fascinating glimpse into the martian landscape. Mars Express has been orbiting Mars since 2003, studying its surface, atmosphere, and geological phenomena.

The True Colors of Mars: Debunking the Red Planet Myth.

The European Space Agency has released a new mosaic image of Mars, captured by the High Resolution Stereo Camera on Mars Express, revealing a more complex and accurate view of the planet than previously possible. The image shows veins of contrasting colors, including blue, gray, and black, indicating areas of volcanic activity and water-worn minerals. The mosaic also captures immense detail in Valles Marineris, the biggest canyon in the solar system. The obsessive search for past water on Mars is a quest to prove the Red Planet was once wet, warm, and more Earth-like, and could have supported primitive Martian life.
