An on-board video camera captured the crucial moment the Mars Curiosity Rover shed its heat shield and descended to the surface of Mars, one of the most perilous steps in an already high-risk mission.
The success of the $2.5 billion (£1.5 billion) mission hinged on the rover safely making it down, having slammed into the Martian atmosphere at 13,200mph before an array of devices slowed its final descent.
As the rover nears the ground, audio recordings from inside the the jet propulsion laboratory (JPL), Nasa’s planetary science headquarters, reveal an atmosphere of tense excitement, before engineer Allen Chen announces "touchdown confirmed" to huge cheers and screams from the assembled scientists.
