The geology at the Curiosity Mars rover landing site has turned out to be everything the mission team wanted, says Nasa project scientist John Grotzinger.

The vehicle touched down inside a deep depression called Gale Crater, which has a 5.5km-high mountain at its centre.

Prof Grotzinger spoke to our correspondent Jonathan Amos about his first impressions of the touchdown location.
