NASA's Curiosity rover recently snapped a stunningly detailed "postcard" of the Martian landscape, showing the sunlight shifting between morning and afternoon. The wandering robot beamed the picturesque scene back to Earth shortly after waking up from a "brain boosting nap."

The rover captured the memento April 8, or Sol 3,794 (Martian days) of its mission, shortly before leaving the Marker Band Valley, a region where it discovered signs of an ancient lake in 2022. The photoshoot was one of the first actions Curiosity completed after hibernating for a software update between April 3 and April 7, which included 180 individual upgrades — the most important of which will allow the rover to process images of its surroundings faster and reduce wear on its tires, which will help it to move much quicker across the Martian landscape, Live Science's sister site Space.com reported.

The new panorama is a composite of two images, one taken in the morning and the other in the afternoon. Combining the light of the sun from two different angles creates an image with much greater detail than a standard photograph, NASA representatives wrote in a statement.

"Anyone who's been to a national park knows the scene looks different in the morning than it does in the afternoon," Doug Ellison, an engineer at NASA's Jet Propulsion Laboratory in Southern California who runs Curiosity's camera team, said in the statement. "Capturing two times of day provides dark shadows because the lighting is coming in from the left and the right, like you might have on a stage – but instead of stage lights, we're relying on the Sun."

The original image is actually black and white, but color has been added to highlight the rock formations and to mimic the color of the sky during morning and afternoon.

This is the second time that Curiosity has captured an image in this way. The rover also snapped a similar split-time photo in November 2021. However, the latest postcard is much more detailed than its first attempt, likely because the photo was snapped during Mars' winter when there is less atmospheric dust, Ellison said. (The rover rarely takes images like this because the rover would need to remain in one place all day, which limits how much data it can collect.)

The new postcard is not the only spectacular scene that Curiosity has recently snapped. In February, the rover captured one of the clearest-ever images of "sun rays," a phenomenon caused by the sun's rays shining through clouds while the sun is below the horizon, on the Red Planet.

In addition to grand landscape shots, the rover has also turned its camera downward to shoot some up-close shots of interesting mineral formations. In February 2022, the rover caught a glimpse of a flower-like mineral and, on April 15 this year, it spied a tiny rock in the shape of a book.
