NASA Stuns the World with Rare Side View of Massive Mars Volcano Towering Over Alien Clouds
NASA’s Mars Odyssey snaps unprecedented horizon shot of Arsia Mons, revealing new secrets about Martian clouds and volcanic giants.
- 12 miles: Height of Arsia Mons, nearly double Hawaii’s Mauna Loa.
- 4th side-view image: Only since 2023 has Odyssey captured the Martian horizon.
- 24+ years: NASA’s Odyssey has orbited Mars since 2001, the longest running mission.
- 1100 miles: Length of the rare Arsia Mons Elongated Cloud over southern Mars.
A NASA spacecraft has delivered one of the most breathtaking glimpses yet of the Red Planet’s mysterious morning. In a move never before achieved, the Mars Odyssey orbiter snapped a dramatic side view of Arsia Mons — a long-extinct volcano rising more than 12 miles above the Martian surface.
As dawn crept over Mars on May 2, Odyssey’s camera caught Arsia Mons erupting through a glowing emerald haze in the upper atmosphere, its summit looming above swirling fog. This colossal Martian peak dwarfs Earth’s mightiest volcanoes and stands as a stone guardian to the planet’s ancient past.
The image isn’t just a pretty picture; it unlocks new insights about Mars’ unique weather and monster volcanoes. Odyssey had to twist 90 degrees from its usual mapping position, gazing toward the Martian horizon for a perspective once thought impossible.
What Makes This Image So Revolutionary?
Mars Odyssey has typically photographed Mars by pointing straight downward from its 250-mile-high orbit. But in the last two years, scientists began tilting the spacecraft sideways—a maneuver that now reveals the Martian horizon, much like astronauts see Earth’s curved edge from NASA’s International Space Station. This fresh angle lets researchers peek at dramatic cloud decks, seasonal fog, and elusive atmospheric events once missed by previous missions.
Why Is Arsia Mons So Special?
Arsia Mons, part of the three-peak Tharsis Montes formation, dominates the Martian skyline alongside its even taller neighbors. Unconstrained by the tectonic activity that keeps Earth’s volcanoes in check, Mars’s volcanoes have grown to record heights. The Tharsis region is home to the largest volcanic mountains in the solar system, as confirmed by ongoing research on NASA’s Mars mission site and volcanology studies.
But there’s more: Arsia Mons is famously the cloudiest of its trio. Scientists are now unraveling the secrets of the “Arsia Mons Elongated Cloud”—a temporary, water-ice formation stretching more than 1,100 miles across the planet’s surface each spring, only to vanish within a few hours. The latest Odyssey image shows this rare weather event in stunning detail, helping NASA trace the evolution of Mars’ aphelion cloud belt—a massive, equatorial cloud system that appears when Mars is farthest from the sun.
Q&A: What Did Scientists Learn from This Side View?
Q: How does this help us understand Mars’ atmosphere?
A: The horizon images reveal how Martian clouds—both water ice and carbon dioxide—shift with the planet’s seasons, offering new clues about climate cycles and atmospheric change.
Q: Is this technique new for Mars Odyssey?
A: Absolutely—the sideways camera angle has only been used four times since 2023, delivering unique scientific data that was never part of Odyssey’s original mission plan.
Q: Could these images help with future Mars missions?
A: Yes. By studying atmospheric behavior and cloud formations, NASA can better predict weather hazards and surface conditions for future landers, rovers, and even potential human explorers.
