Nostalgia for a generation who has grown up with news of space shuttle Discovery.
The USspaceshuttle blasted off for the last time on a mission that marks the beginning of the end of the shuttle era, reports guardian.co.uk.
Around 40,000 guests gathered at Kennedy Space Centre to watch the launch of the historic mission, carrying six astronauts and the first humanoid robot into space.
"For those watching, get ready to witness the majesty and the power of Discovery as she lifts off one final time," the mission commander Steven Lindsey radioed just before the launch at 21.53 GMT.
