At 3 hours before liftoff, or
T minus 3 hours, 7 astronauts
finish dressing in orange NASA
spacesuits at the Kennedy Space
Center in Florida. They step into a
bus that takes them to the shuttle
launch pad. As they exit the bus,
the astronauts seem small
compared to the 122-foot-tall
orbiter that will be their
home for the next two weeks.
