NASA's Curiosity Rover Captures a Martian Day

In a first for the mission, the rover used its Hazard-Avoidance Cameras to record a 12-hour sequence of its shadow moving across the Martian surface.

NASA's Curiosity rover captured a 12-hour sequence of its shadow moving across the Martian surface during a communication-limited period known as Mars' solar conjunction.
The rover used its Hazard-Avoidance Cameras (Hazcams) to record the time-lapse videos, a first for the mission.
Although the team hoped to capture clouds or dust devils that could reveal more about Mars' weather, no significant weather events were noted in the footage.
The videos show the rover's silhouette shifting as the day moves from morning to afternoon to evening, effectively serving as a rudimentary sundial.
The rover is now back to its regular activities, including taking images of regions called Crescent Meadow and Sawtooth Peak and looking for clouds and dust in the air.
