The lifting fixture nicknamed the "Birdcage" is lifted by a crane to test the load capability. The Birdcage will be used 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 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.
