Olympus Mons — 111 Places in Space That You Must Not Miss

Olympus Mons — 111 Places in Space That You Must Not Miss
Olympus Mons — 111 Places in Space That You Must Not Miss Described in 111 Places in Space That You Must Not Miss, Olympus Mons is a mountain of true superlatives. Rising 21 km above the plains of Mars, this colossal shield volcano was built over billions of years above a fixed hotspot—and aided by Mars’ lower gravity. Dormant, not extinct, its most recent lava flows may be as young as 2 million years, a geologic heartbeat ago. Mars Express / ESA, DLR, FU Berlin, HRSC / image processing Andrea Luck, CC BY-2.0
