A tracking camera on Launch Pad 39B captures the flames of Space Shuttle Atlantis' three main engines as Altantis hurtles into space on mission STS-112. The shoreline of the Atlantic Ocean is visible in the background. Liftoff occurred at 3:46 p.m. EDT. Atlantis carries the S1 Integrated Truss Structure and the Crew and Equipment Translation Aid (CETA) Cart A. The CETA is the first of two human-powered carts that will ride along the ISS railway, providing mobile work platforms for future spacewalking astronauts. On the 11-day mission, three spacewalks are planned to attach the S1 truss.
