Space shuttle Atlantis has launched from the US Kennedy Space Center in Florida, the first shuttle mission of 2007.
The countdown to the launch went smoothly, to the delight of many spectators.
And the weather was kind too, as the shuttle took off in near perfect conditions.
In less than nine minutes it reached orbit, before heading for the International Space Station, on an 11-day mission.
Spectators had gathered to watch the awe-inspiring sight.
As the shuttle disappeared from sight, it left behind a magnificent view.
Once they reach the space station, the seven astronauts will continue installation work, including a new pair of solar panels.
