In the Vehicle Assembly Building at NASA's Kennedy Space Center, a crane lifts a frustum high above the transfer aisle. The solid rocket booster segment is being moved into a high bay where it will be added to the stack being prepared for space shuttle mission STS-122, targeted for launch in December. On this mission, Atlantis will carry the Columbus Laboratory, the European Space Agency's largest contribution to the International Space Station. Columbus is a multifunctional, pressurized laboratory that will be permanently attached to U.S. Node 2, also called Harmony, to carry out experiments in materials science, fluid physics and biosciences, as well as to support a number of technological applications.
