When Was Olympus Mons Discovered on Mars?
The true story of Olympus Mons'' discovery: the difference between sighting a feature through a telescope and scientifically confirming a planetary giant.
Olympus Mons, volcano on the planet Mars, the highest point on the planet and the largest known volcano in the solar system. Centered at 19° N, 133° W, Olympus Mons consists of a central edifice 22 km (14 miles) high and 700 km (435 miles) across.

Its immense size caused Mars' crust and mantle to shift approximately 20 degrees. Olympus Mons is a shield volcano, growing slowly due to Mars' lack of plate tectonics.
Named after the mythical home of the Greek gods, Olympus Mons was first observed in the late 1800s, but its true enormity was only revealed in the 1970s when NASA's Mariner 9 space probe provided detailed images.
The formation of Olympus Mons began around 3.5 to 4 billion years ago during the Hesperian epoch, a period marked by extensive volcanic and tectonic activity on Mars. Like Earth's Hawaiian volcanoes, Olympus Mons is a shield volcano, formed by successive eruptions of low-viscosity basaltic lava.

Olympus Mons is the largest volcano in the solar system, located in the Tharsis Montes region of Mars. It was first spotted from Earth in the 19th
Olympus Mons is a massive shield volcano located on Mars and is recognized as the tallest mountain in the solar system. Standing at approximately 84,400 feet (25,750 meters) high, it is nearly three times
Olympus Mons, volcano on the planet Mars, the highest point on the planet and the largest known volcano in the solar system. It consists of a central edifice 22 km (14 miles) high and
Found in the Tharsis Montes region near the Martian equator, Olympus Mons is one of a dozen large volcanoes, many of which are ten to a hundred times taller than their terrestrial
Astronomers first recognized Olympus Mons as a bright albedo patch called Nix Olympica in 19th‑century telescopic maps, but its true size and nature — a 600–700 km wide shield volcano
Olympus Mons reaches an astonishing height of about 16 miles (26 kilometers), or around three times as tall as Mount Everest.
Olympus Mons is composed primarily of basaltic lava, similar to the material found in shield volcanoes on Earth. Basalt is a low-viscosity, low-silica rock that allows lava to flow easily over great distances.
Olympus Mons is not only the largest volcano in the Solar System but also one of the most fascinating geological features. Standing at nearly 72,000 feet (22 km; 13.6 mi)—almost 2.5
Lying in the Tharsis Montes region of the Martian landscape, Olympus Mons is a sprawling giant of a volcano, towering 22km above the surrounding region, and a total of 27km above the
