NASA’s Odyssey spacecraft, orbiting Mars since 2001, has reached a remarkable milestone by completing its 100,000th orbit around the Red Planet. To mark the occasion, the mission team has released a detailed panorama of Olympus Mons, the tallest volcano in the solar system. The exceptional image, captured in March, offers a new perspective on the Martian giant and reveals fascinating details about the Red Planet’s atmosphere and surface.
Olympus Mons: the Martian giant
Olympus Mons is an iconic feature of Mars that is known for being the most imposing volcano in the solar system. Rising to 27 kilometers above the Martian surface, it far exceeds all terrestrial volcanoes. Its base stretches over 600 kilometers near the Martian equator, forming a massive structure that dominates the surrounding landscape. This volcano is not only a geological landmark, but also a crucial subject of study for understanding volcanic processes and the geological evolution of Mars. In addition to its impressive size, Olympus Mons exhibits intriguing atmospheric phenomena. Recently, astronomers have notably discovered an ephemeral morning frost covering the summit of the volcano for a few hours each day. This discovery offers new insights into the circulation of ice from the poles across the arid world of Mars. Studying these phenomena could help us understand Martian water cycles and their impact on the climate and geology of the planet.
An image captured by Odyssey
For celebrate the cape of 100,000 orbitsscientists used the Odyssey spacecraft to capture a panorama of the enormous structure. The unique image was obtained by ordering the spacecraft to slowly rotate so that its camera pointed toward the Martian horizon. This technique, similar to that used by astronauts on the International Space Station to photograph Earth, revealed the grandeur of Olympus Mons in a single view.

Above this band, a thin layer of purple suggests a mix of atmospheric dust and bluish water ice clouds. The blue-green layer at the top of the image marks where the water ice clouds rise about 30 miles (48 kilometers) into the Martian sky. These details provide valuable information about the Martian atmosphere and its interactions with the planet’s surface. As for Odyssey, the 100,000 orbit milestone means that the probe has traveled more than 2.2 billion kilometers around Mars. Although it is not equipped with a fuel gauge, engineers estimate that the ship has enough fuel left about 4 kilograms of propellantwhich is enough to extend the mission until the end of 2025 and continue to provide high-quality scientific data.
