NASA's Odyssey spacecraft, the longest-running mission at Mars, circled the Red Planet for the 100,000th time today, the mission team announced in a statement.
To celebrate the milestone, the space agency released an intricate panorama of Olympus Mons, the tallest volcano in the solar system; Odyssey captured the view in March. The volcano's base sprawls 373 miles (600 kilometers) near the Martian equator while it soars 17 miles (27 kilometers) into the planet's thin air. Earlier this month, astronomers discovered ephemeral morning frost coating the volcano's top for a few hours every day, offering fresh insights into how ice from the poles circulates throughout the parched world.
