Inside the mission to Mars

 

We've only recently been able to get an up-close look at the infamously red surface of Mars, but detailed images of the planet brought back by the Mars Curiosity Rover are giving people an entirely different perspective.

For two years, writer Marc Kaufman embedded with the scientists behind the mission, and he documents the experience in his new book, Mars Up Close.
The book also includes some incredible - and unexpected - photographs of the Martian terrain.
Kaufman spoke to the BBC's Katty Kay about exploring the red planet.
