Space Shuttle Discovery lifts off

As the ground fills with smoke and steam, Space Shuttle Discovery creates its own fireworks display, fitting for the first ever launch to be made on US Independence Day. It was the third launch attempt in four days, the others were scrubbed due to weather concerns. Liftoff for mission STS-121 was at 14:38 EDT. During the 12-day mission, the STS-121 crew of seven tested new equipment and procedures to improve Shuttle safety, as well as deliver supplies and make repairs to the International Space Station. Landing was 17 July 17 at Kennedy's Shuttle Landing Facility, USA.
