Liftoff of space shuttle Atlantis! Mission STS-132 is officially under way as the shuttle and its all-veteran crew of astronauts rise up and away from NASA’s Kennedy Space Center in Florida following an on-time launch at 2:20 p.m. EDT. In approximately two minutes, Atlantis’ twin white solid rocket boosters will burn out and separate, eventually falling back to the Atlantic Ocean. The shuttle’s trio of main engines will propel the vehicle on the rest of its eight-and-a-half-minute climb to orbit, assisted by the two orbital maneuvering system engines.
