Nasa's Mars InSight mission to dig into red planet to answer its deepest mysteries

Nasa is about to launch a rover to dig deep into Mars. The engineers behind the mission hope that it could find life and the answer to other mysteries about how the planet was formed. The InSight mission will set off six years after Nasa last sent one of its robot travellers to investigate the Red Planet. And it will continue the same work, digging into the planet to try and learn more about what is hidden down there. It will take the first measurements of "Marsquakes", for instance, and will look into why it seems to wobble a little as it spins around.
