NASA’s Curiosity Rover Captures Dawn Over Wind-Carved Cliffs in Gale Crater
Curiosity captured dawn over wind-carved yardangs in Gale Crater at 8:30 a.m. Mars time. The image is a six-photo Mastcam panorama showing blue foreground tones and distant yardangs.
19 outlets told this the same way.
Curiosity dawn image
NASA released an image of dawn on the Martian surface taken by its Curiosity rover, showing sunlight bathing jagged crags formed billions of years ago.
Curiosity snapped the scene with its Mastcam camera about an hour after the sun rose above a landscape featuring wind-carved cliffs in the distance, and the image was taken on Aug. 11, 2026.
Curiosity landed in 2012 in Gale Crater near the Martian equator, and since 2014 it has been climbing Mount Sharp, a 5-kilometre-tall mountain rising from the crater floor.
Ashwin Vasavada of NASA's Jet Propulsion Laboratory said, "The bright craggy peaks in the distance are a rock layer that is quite different in appearance from all the layers the rover has driven through so far."
Yardangs and timing
Curiosity’s new panorama highlights distant features called yardangs, and NASA said the yardang layer most likely formed about 3 billion years ago. Vasavada said the yardang layer spans about 16 kilometres across the northwestern reaches of Mount Sharp, and he added that the yardang layer does not appear to be part of the continuous stack of layers that make up the layer-cake of Mount Sharp.
Vasavada described the yardang layer as being "above what geologists call an unconformity: a gap in time where previous layers eroded down before new layers were deposited on top." NASA also said Curiosity has gained upwards of 0.6 miles (1 km) in elevation on its gradual ascent, the most ever climbed on Mars, and it framed the yardang layer as the stack’s end point in the area where the rover is climbing.
Next steps in 2027
NASA said it hopes Curiosity will reach the yardang layer in 2027 or 2028, at which time it will use its instruments to scrutinize the geology there. NASA’s Science Mission Directorate said Curiosity’s Mastcam panorama was made up of six individual images stitched together after being sent back to Earth, and it said the panorama was processed without the usual white balancing to preserve the early morning appearance.
Vasavada said scientists think the bright peaks once were wind-blown sediment, "maybe sand or maybe even ash that blew into the crater from nearby volcanic activity." NASA said Curiosity is one of two NASA rovers operating on Mars, and it noted that the Perseverance rover is currently traversing the margins of Jezero Crater in the northern hemisphere.
