Space Shuttle Atlantis Launches
Space shuttle Atlantis soared into orbit from Launch Pad 39A at NASA’s Kennedy Space Center in Florida on the STS-132 mission to the International Space Station at 2:20 p.m. EDT on May 14. This was the last planned launch for Atlantis. There are only two more space shuttle launches left before the fleet is retired.
