Matt Damon wants to go to Mars.

The 44-year-old actor has four daughters with his Argentine wife Luciana Barroso - stepdaughter Alexia, 17, and Isabella, nine, Gia, six, and five-year-old Stella - and has revealed he craves the opportunity to escape the everyday stresses of family life by travelling into space.

Matt - who stars in the new Ridley Scott-directed sci-fi movie 'The Martian', in which he plays an astronaut - joked: ''It's funny because in my life I'm rarely by myself. With four kids I could use some time alone on Mars.''

Despite being among the most bankable stars in Hollywood, Matt said his stable family life means he finds it easy to escape the attention of the paparazzi cameras and fans.

The Oscar-winning star - who's previously dated the likes of Minnie Driver and Winona Ryder - told The Daily Telegraph newspaper: ''I'm a married man with kids and there's no scandal about me.

''So long as the photographers get an updated picture every six months, they're OK.

''A picture of us isn't as valuable as a picture of somebody who may cause some scandal and I don't think I've done anything to create any mystique around myself.''
