NASA's Curiosity rover captures dawn on Mars

Key points

• NASA's Curiosity rover has captured a striking image of dawn on Mars, showing sunlight bathing jagged crags formed billions of years ago. The rover, which landed in 2012, has been climbing Mount Sharp, a 5-kilometre-tall mountain in Gale Crater.
• The image, taken in August, reveals a rock layer that scientists believe was once wind-blown sediment, possibly from nearby volcanic activity.
• Curiosity has been studying the geology and climate of Mars and examining whether it once harboured conditions conducive to microbial life.
