Mars Odyssey Captures First Horizon Panorama of Arsia Mons
- NASA's Mars Odyssey orbiter captured a unique image of Arsia Mons poking through morning clouds on May 2, 2025, at Mars.
- The orbiter, launched in 2001 and the longest-running spacecraft around another planet, began this horizon imaging work in 2023 to study Martian clouds.
- Arsia Mons, a 12-mile-high ancient volcano twice Earth's Mauna Loa height, is part of Tharsis Montes and often cloaked in early morning water ice clouds at aphelion.
- Operations lead Jonathon Hill remarked that they chose to image Arsia Mons with the expectation that its peak would rise above the early morning cloud cover, a hope that was fulfilled. Meanwhile, scientist Michael D. Smith highlighted that the photographs show clear seasonal variations, providing valuable insights into the changing Martian atmosphere.
- This image offers new insights into Mars's atmospheric evolution by showing cloud patterns and seasonal changes, important for weather models and future human exploration.

Arsia Mons, which dwarfs Earth’s tallest volcanoes, and its two neighboring volcanoes are often surrounded by water ice clouds, especially in the early morning. The image released Friday marks the first time one of the volcanoes has been imaged on the planet’s horizon, NASA said. Odysse…
