At its Houston Product Support Center located near NASA's Johnson Space Center, Boeing revealed its first full-scale model of the CST-100, a gumdrop-shaped spacecraft that can seat up to seven crew members.

On Monday (July 22), two NASA astronauts were strapped into the capsule mockup to undergo flight suit evaluations aimed at validating the CST-100's interior design. [Photos: Boeing's CST-100 Space Capsule]
