00:00:07.000 --> 00:00:16.000
After a rain delay imposed by Tropical Storm Alberto, the seven-member crew of STS-121 flew into Kennedy Space Center

00:00:16.000 --> 00:00:22.000
for three final days of training in preparation for a July liftoff.

00:00:22.000 --> 00:00:27.000
The crew's first full day in Florida began at Launch Pad 39B.

00:00:27.000 --> 00:00:35.000
In the shadow of Discovery, Commander Steven Lindsey and the rest of his team took questions from the media.

00:00:35.000 --> 00:00:38.000
The crew's attention then turned to safety.

00:00:38.000 --> 00:00:44.000
Suited up with all of their flight gear, the astronauts practiced firefighting techniques and escaping

00:00:44.000 --> 00:00:48.000
from the shuttle in the event of an emergency.

00:00:48.000 --> 00:00:54.000
The second day of the event featured a full dress rehearsal for an actual launch.

00:00:54.000 --> 00:01:01.000
Once again emblazoned with their signature orange suits, the STS-121 crew boarded Discovery and worked with launch

00:01:01.000 --> 00:01:06.000
controllers through a simulated countdown

00:01:06.000 --> 00:01:12.000
Training wrapped up on day three after the crew carefully inspected the Leonardo module secured inside Discovery's

00:01:12.000 --> 00:01:15.000
payload bay.

00:01:15.000 --> 00:01:20.000
The traditional "once over" allows the astronauts to ensure the cargo is free of any hazards that could cause

00:01:20.000 --> 00:01:24.000
problems during the mission.

00:01:24.000 --> 00:01:30.000
Seeing that the shuttle, payload and launch team are ready for flight, the STS-121 crew members returned to their

00:01:30.000 --> 00:01:41.000
home base in Houston, Texas confident that everything is shipshape and ready for liftoff.

00:01:41.000 --> 00:01:46.000
