Nasa Launches Mars Seismic Probe

Nasa's latest mission to Mars has blasted off from California, carrying a lander that will investigate the interior of the Red Planet. So how long before humans follow the robots?

Also in the programme: a number of strong earthquakes have hit Hawaii's Big Island, a day after the eruption of the Kilauea volcano; and memories of the student protests in Paris in May 1968.
