NASA's Curiosity rover takes striking image of dawn on Mars
Curiosity landed in 2012 in Gale Crater near the Martian equator
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 as the car-sized vehicle continues to explore Earth's planetary neighbour.
asserted
vehicle → take → neighbour
Curiosity landed in 2012 in Gale Crater near the Martian equator, and since 2014 has been climbing Mount Sharp, a five-kilometre-tall mountain rising from the crater floor.
asserted
Curiosity → 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.
asserted
sun → take → distance
"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, the Curiosity project scientist.
asserted
Vasavada → drive → California
NASA believes that some kind of wind-blown sediment landed in the crater from nearby volcanic activity.
asserted
kind → believe → activity
Once it hardened into rock, "eons of wind carved up the rock layer into ridges called yardangs," Vasvada said.
asserted
Vasvada → harden → ridges
The yardang layer most likely formed about three billion years ago, around the same time as the rest of the mountain, according to Vasavada.
uncertain
layer → form → Vasavada
This layer spans about 16 kilometres across the northwestern reaches of Mount Sharp.
asserted
layer → span → Sharp
But the layers appears to have been added on later, he said.
asserted
he → appear → ?
"It's above what geologists call an unconformity: a gap in time where previous layers eroded down before new layers were deposited on top.
asserted
layers → call → top
"
Rover making gradual ascent up mountain
The rover on its gradual ascent up the mountain has gained upwards of nearly a kilometre in elevation, the most ever climbed on Mars, according to NASA.
uncertain
rover → make → NASA
Mount Sharp is built of layers, each recording a period of the planet's geological past.
asserted
each → 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

Vasavada said NASA hopes Curiosity will reach the yardang layer in 2027 or 2028, at which time it will use its instruments to scrutinize the geology there.
asserted
it → add → geology
Curiosity has been studying the geology and climate of Mars and examining whether it once bore conditions conducive to harboring 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.
asserted
that → have → Valley
You can almost feel the silence and the endless open space under the sky," Vasavada said.
asserted
Vasavada → feel → sky
"But as familiar as that sounds, the sky is orange and the sunrise has shades of blue.
asserted
sunrise → sound → blue
