Atlantis has been in space 32 times since 1985, and orbited the earth 4,648 times, but she's about to make her last journey.
The famed space shuttle is scheduled for an 11:26 am liftoff, weather permitting. After days of unrelenting rain, the skies cleared Friday morning and forecasters are optimistic that Atlantis will launch on time.
Hundreds of thousands of people have flocked to Florida's Space Coast to view the last U.S. shuttle depart from Kennedy Space Center. Atlantis will take 12 days to carry 8,000 lbs. of supplies to the international space station before returning to Earth for good.
