This animation shows the scale differences between Mars and Earth, as well as the staggering contrast between Mauna Loa and Olympus Mons.

When measured from the ocean floor, Mauna Loa reaches around 10 kilometers in height, while Olympus Mons soars to a staggering 23 kilometers. 🌋 Animation: NASA/Goddard Space Flight Center Scientific Visualization Studio, and Virginia Butcher (SSAI) | The Planetary Soci
