Opportunity's Devilish View from on High

From its perch high on a ridge, NASA's Mars Exploration Rover Opportunity recorded this image of a Martian dust devil twisting through the valley below. The view looks back at the rover's tracks leading up the north-facing slope of "Knudsen Ridge," which forms part of the southern edge of "Marathon Valley."

Opportunity took the image using its navigation camera (Navcam) on March 31, 2016, during the 4,332nd Martian day, or sol, of the rover's work on Mars.

Dust devils were a common sight for Opportunity's twin rover, Spirit, in its outpost at Gusev Crater. Dust devils have been an uncommon sight for Opportunity though.

Just as on Earth, a dust devil is created by a rising, rotating column of hot air. When the column whirls fast enough, it picks up tiny grains of dust from the ground, making the vortex visible.

During the uphill drive to reach the top of Knudsen Ridge, Opportunity's tilt reached 32 degrees, the steepest ever for any rover on Mars.

NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Exploration Rover Project for NASA's Science Mission Directorate, Washington.
