NASA's 2001 Mars Odyssey orbiter captured this incredible image of the giant shield volcano Arsia Mons, poking through the cloud tops at Martian dawn. Arsia and the other megavolcanoes on Mars are so tall they're often surrounded by water ice clouds in the early morning. Odyssey is normally staring straight down, so to capture this unique angle, it had to rotate 90 degrees while in orbit so that it could capture a side perspective view of the volcano.

The 2001 Odyssey spacecraft captured a first-of-its-kind look at Arsia Mons, which dwarfs Earth’s tallest volcanoes.
