NASA has released a new image showing both morning and afternoon on Mars<\/a> at a site called \u2018Marker Band Valley\u2019, captured by the Curiosity rover<\/a> as it left the region behind.<\/p>\n

The rover has been exploring a feature called Mount Sharp, which stretches 5km high within Gale Crater, where the Curiosity has been since landing there in 2012.<\/p>\n

In this new image, Curiosity is looking backwards relative to its direction of travel, capturing its own tracks and, in the distance, Marker Band Valley.<\/p>\n

This winding area is likely the site of an ancient lake, unexpectedly discovered by the rover.<\/p>\n

Perhaps what\u2019s most stunning about this new image is the inclusion of both morning and afternoon within the same scene, providing a glimpse of what it\u2019s like to witness the day draw in on Mars.<\/p>\n

The image was composed using two black-and-white panoramas captured by Curiosity, with colour added by the NASA team at a later stage.<\/p>\n

Blue has been added to sections showing the morning scene, and yellow to parts taken in the afternoon.<\/p>\n

The two images were captured on 8 April 2023 at 09:20 and 15:40, local Mars time.<\/p>\n

Each panorama took 7.5 minutes to capture, and each consists of 5 individual images stitched together.<\/p>\n

And while it may have been springtime here on Earth in the northern hemisphere, on Mars it was actually winter when these images were taken.<\/p>\n

\u201cAnyone who\u2019s been to a national park knows the scene looks different in the morning than it does in the afternoon,\u201d says Curiosity engineer Doug Ellison of NASA\u2019s Jet Propulsion Laboratory in Southern California, who planned and processed the images.<\/p>\n

\u201cCapturing 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 \u2013 but instead of stage lights, we\u2019re relying on the Sun.\u201d<\/p>\n
