NASA's rover Curiosity has checked-in on Mars - using the mobile application Foursquare.
The rover is the first to check-in on another planet, allowing users of the app to follow the rover's whereabouts and see photos taken while it explores the Red Planet.
David Weaver, associate administrator for communications at NASA Headquarters in Washington, said the use of Foursquare will "help to involve the public with the mission and give them a sense of the rover's travels through Gale Crater".
NASA hoped Curiosity's use of Foursquare would "generate an interest in science, technology, engineering and mathematics".

Curiosity landed in Gale Crater last month and is now making its way towards the 5km-tall Mount Sharp, as part of its 23-month exploration of Mars.
