Even in its non-functional state, NASA's Curiosity Rover has managed to serve as a fascinating Martian sundial, providing captivating timelapse videos showcasing a day on the red planet.
In preparation for the Mars solar conjunction, a phase where the Sun aligns between Earth and Mars, the rover was tasked with recording videos. During this celestial alignment, commands to the spacecraft were temporarily halted to avoid potential interference caused by solar plasma affecting radio communications.
Typically, Curiosity relies on its Hazcams to identify rocks, slopes, and potential hazards. However, with most other activities on hold during the conjunction, the team creatively repurposed the Hazcams to capture 12 hours of snapshots for the first time, aiming to glean additional insights into Mars.
While the footage didn't reveal any noteworthy weather events, the pair of 25-frame videos beautifully document the passage of time, spanning from 5:30 AM to 5:30 PM local time on Mars. The videos showcase the rover's silhouette gracefully shifting across the Martian surface as day transitions from morning to afternoon and eventually to night.
During sunrise, the shadow of Curiosity's 2-meter robotic arm subtly moves to the left, accompanied by the emergence of the rover's front wheels from the darkness on either side of the frame. A circular calibration target mounted on the robotic arm's shoulder becomes visible on the left.
The second video provides a unique perspective from the rear Hazcam, offering a view down the slopes of Mount Sharp to the floor of Gale Crater. This perspective captures the rover's right wheel, along with the shadow cast by its power system. A minor black artifact, appearing around the 17th frame, results from a cosmic ray hitting the camera sensor, adding an intriguing cosmic touch to the Martian timelapse.
