The yellow framework at center is the lifting fixture nicknamed the "Birdcage" that will have the ability to lift the Crew Module, or CM, and Launch Abort System, or LAS, assembly for the Ares I-X rocket and to stack and de-stack the assembly from the Service Module/Spacecraft Adapter assembly. It will also have the ability to lift and to stack and de-stack Stack-5 (all of the above components) from the Ares I-X flight test vehicle in the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. Ares I-X is the test flight for the Ares I. The I-X flight will provide NASA an early opportunity to test and prove hardware, facilities and ground operations associated with Ares I. The launch of the 321-foot-tall, full-scale Ares I-X, targeted for July 2009, will be the first in a series of unpiloted rocket launches from Kennedy. When fully developed, the 16-foot diameter crew module will furnish living space and reentry protection for the astronauts, while their launch abort system will provide safe evacuation if a launch vehicle failure occurs.
