KENNEDY SPACE CENTER, FLA. - In the Vehicle Assembly Building at NASA's Kennedy Space Center, a solid rocket booster segment is lifted off its transporter below. The segment is being lifted up into high bay 3 and will be placed on mobile launcher platform No. 2 for use on mission STS-115. The mission will deliver a truss and other key components to the International Space Station. Launch is currently scheduled for late August. Photo credit: NASA/Charisse Nahser
