Mars: Nasa lands InSight robot to study planet's interior

The US space agency Nasa has landed a new robot on Mars after a dramatic seven-minute plunge to the surface of the Red Planet. The InSight probe aims to study the world's deep interior, and make it the only planet - apart from Earth - that has been examined in this way. Confirmation of touchdown came through on cue at 19:53 GMT. It ended an anxious wait in which the robot radioed home a series of updates on its descent. Nasa's mission control at California's Jet Propulsion Laboratory (JPL) erupted into cheers when it became clear InSight was safe on the ground.
