A former director at the European Space Agency says the landing of the Philae probe on a comet was like watching a "birth".

David Southwood, former ESA director of space and robotic exploration, became involved with the project 20 years ago.

He said the landing was a "big step" for the world and an "incredible achievement" for everyone involved.

"It's like having a baby born... You've been waiting and suddenly everything is there in front of you. This is discovery."
