In preparation for the Return to Flight mission, STS-114, the Space Shuttle Discovery crew spent three days at NASA's Kennedy Space Center in Florida the first week of May participating in the Terminal Countdown Demonstration Test. This milestone, highlighted by a countdown dress rehearsal on Wednesday morning, marked the first time astronauts boarded a Shuttle on the launch pad in more than two years.
