SDO Spacecraft Is Lowered Onto Its Propulsion Module

Integration and Testing - A technician monitors as the SDO spacecraft is lowered onto its propulsion module. The delicate operation took place in the clean room at NASA's Goddard Space Flight Center in Greenbelt, Md. In a relatively short amount of time (30 minutes) engineers and technicians lowered the spacecraft onto the propulsion module with surgical precision. Credit: NASA/Barbara Lambert
