Over the course of 12 hours, the Curiosity rover operated by the National Aeronautics and Space Administration (NASA) took two animated pictures of the Martian landscape, one of which featured its own shadow in the foreground.
The rover shared the pictures on Thursday, showcasing the beauty of Mars beyond our atmosphere and the six-wheeled vehicle’s view of a typical Martian day from sunrise to sunset.
The pictures were uploaded to X, formerly known as Twitter, by the official Curiosity account, with the caption, “Hey look, I’m a sundial! Well, not quite, but I did manage to get a sol to take in my surroundings. I observed the Martian weather and dust with my hazard cameras during solar conjunction.”
On November 8, from 5:30 a.m. to 5:30 p.m. local time, Curiosity used its Hazard-Avoidance Cameras, which aid in identifying obstacles and terrain, to take breathtaking pictures of the planet.
According to NASA, the photos were shot prior to the Mars solar conjunction, which occurs every two years and causes communication problems between Earth and Mars for two weeks.
Although the Nasa scientists were unable to photograph any Martian clouds or dust devils, the stitched clips offer an amazing depiction of a day on Mars and Curiosity’s presence during it.
“The shadow of the rover’s 7-foot (2-meter) robotic arm moves to the left, and Curiosity’s front wheels emerge from the darkness on either side of the frame,” the NASA blog post states as the sky brightens during sunrise. A circular calibration target that is fixed on the robotic arm’s shoulder also starts to show up on the left.

“The goal is to evaluate the precision of the Alpha Particle X-ray Spectrometer, a device that finds chemical components on the surface of Mars, by engineers.
The front Hazcam’s autoexposure algorithm chooses exposure times of about one-third of a second during the middle of the day. When dusk falls, that exposure duration extends to over a minute, resulting in the common sensor noise called “hot pixels” that splatters the finished image in white snow.
After eleven years of living on Mars, the spots on the cameras appear to be dust, which is unavoidable.
