NASA's Curiosity rover has captured an image showing dawn over wind-carved cliffs on Mars. The picture was taken at 8:30 am local Mars time and features sunlight illuminating jagged crags formed billions of years ago. These crags, known as yardangs, are rock layers that scientists believe were once sediment hardened by wind erosion into ridges. Curiosity, which landed in Gale Crater in 2012, is currently climbing Mount Sharp and aims to reach the base of these cliffs around 2027 or 2028 for further study.

Story summary
Nasa released a striking image of dawn on Mars captured by its Curiosity rover, which shows sunlight illuminating jagged crags near Mount Sharp in Gale Crater. The car-sized rover, about the size of a Mini Cooper, landed on Mars in 2012 and has been climbing Mount Sharp since 2014. Planetary scientist Ashwin Vasavada from Nasa's Jet Propulsion Laboratory explained that the distant craggy peaks are a rock layer distinct from others explored by Curiosity; these rocks were once wind-blown sediment, possibly sand or ash from nearby volcanic activity, now carved into ridges called yardangs. The image was taken about an hour after sunrise in August by Curiosity's Mastcam camera. Scientists hope to reach the base of these formations sometime around 2027.

In short:
A new image from Mars has been released, showing a dawn over wind-carved cliffs.
asserted
image → release → cliffs
The scene was snapped by NASA's Curiosity rover at 8:30 am local Mars time.
What's next?
Scientists hope Curiosity will reach the base of the crags, known as yardangs, sometime in 2027.
asserted
Curiosity → snap → 2027
NASA has released a striking image of dawn on the Martian surface taken by its Curiosity rover, showing sunlight bathing jagged crags formed billions of years ago.

NASA → release → years
Curiosity, which is about the size of a Mini Cooper, landed in 2012 in Gale Crater near the Martian equator, and since 2014 has been climbing Mount Sharp, a 5 kilometre-tall mountain rising from the crater floor.
asserted
which → land → floor
The image was taken by the six-wheeled rover's Mastcam camera about an hour after the sun rose above a landscape featuring wind-carved cliffs in the distance, in August.
asserted
sun → take → August
"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," said planetary scientist Ashwin Vasavada of NASA's Jet Propulsion Laboratory in California.
asserted
Vasavada → drive → California
"We think it once was wind-blown sediment, maybe sand or maybe even ash that blew into the crater from nearby volcanic activity.
asserted
that → think → activity
"After the sediment hardened into rock, eons of wind carved up the rock layer into ridges called yardangs," the Curiosity project scientist said.
asserted
scientist → harden → ridges
The yardang layer most likely formed about 3 billion years ago, around the same time as the rest of the mountain, according to Mr Vasavada.
uncertain
layer → form → Vasavada
This layer spans about 16 kilometres across the north-western reaches of Mount Sharp.
asserted
layer → span → Sharp
"However, the yardang layer doesn't appear to be part of the continuous stack of layers that make up the layer-cake of Mount Sharp.
asserted
that → appear → Sharp
It was added on a little later.
asserted
It → add → ?
It's above what geologists call an unconformity: a gap in time where previous layers eroded down before new layers were deposited on top," Mr Vasavada said.
asserted
Vasavada → call → top
'You can almost feel the silence'
asserted
You → feel → silence
The rover on its gradual ascent up the mountain has gained upwards of 1km in elevation, the most ever climbed on Mars, according to NASA.
uncertain
rover → gain → NASA
Mount Sharp is built of layers, each recording a period of the planet's geological past.
asserted
Sharp → build → past
In studying these layers, scientists have learned more about bodies of water — lakes and streams — that long ago covered this region, at a time when Mars was wetter and warmer than the cold and desolate place it is today.
asserted
it → study → place
Mr Vasavada said NASA hopes Curiosity will reach the yardang layer in 2027 or 2028, at which time it will use its instruments to scrutinise the geology there.
asserted
it → say → geology
Curiosity has been studying the geology and climate of Mars and examining whether it once bore conditions conducive to harbouring microbial life.
asserted
it → study → life
It is one of two NASA rovers operating on Mars.
asserted
It → operate → Mars
The Perseverance rover is currently traversing the margins of Jezero Crater in the northern hemisphere.
asserted
rover → traverse → hemisphere
"This scene has a wildness that reminds me of a road trip through Monument Valley, Arizona," Mr Vasavada said.
asserted
Vasavada → have → Valley
"You can almost feel the silence and the endless open space under the sky.
asserted
You → feel → sky
But as familiar as that sounds, the sky is orange and the sunrise has shades of blue.
asserted
sunrise → sound → blue
