Mission to Mars: The Curiosity Rover

Launched by NASA in November 2011, the Curiosity rover reached the surface of Mars on 6th August 2012. It landed in the Gale Crater near a mountain named Aeolis Mons.

Around the size of a small car, Curiosity is roaming the Martian landscape and taking readings that will help NASA scientists learn more about the climate and rocks on Mars.

Scientists selected the Gale Crater as the landing site because it has layers of different types of rock that are exposed and able to be sampled.

Each sample can be tested to find out if any of them show signs that microbes could have been present in the past.

Curiosity is also sending back data that will show if water exists or ever existed on Mars.

After analysing data sent from Curiosity for one year, scientists have discovered that Mars could have supported simple life forms, or microbes, in the ancient past.
