After a seven-month journey of more than 500 million kilometres, Nasa's Mars InSight probe has finally reached its destination and touched down on Mars. The probe aims to study Mars' deep interior, and make it the only planet - apart from Earth - that has been examined in this way. Newsday's James Copnall spoke to Professor Tom Pike, he's part of the science team behind the mission. James began by asking about the probe's complicated landing.
