The CM-LAS and the Birdcage

Posted on by .

Ares I-X hardware has the best nicknames.

These images show the Stack-5 Ground Support Equipment Lifting Fixture or as it is known to the I-X team, the “birdcage” being lowered over the Crew Module/Launch Abort System (CM/LAS) for a fit check. The birdcage is a metal framework that was collaboratively built and designed at the Langley Research Center in Langley, Virginia and Kennedy Space Center in Florida. It fits over the CM/LAS in order for it to be moved and stacked creating super stack 5.

The “birdcage” is bolted to the bottom of the crew module portion of the CM/LAS and then lifted into place (by one of the 325 ton overhead cranes in the VAB) and placed on top of the service module, which is already stacked on top of the Ares I-X rocket.  Technicians can then remove the bolts — from inside the CM — and the “birdcage” is removed.

NASA Langley Ares I-X Rocket Elements Arrive at NASA Kennedy Space Center

It takes a mighty big airplane to transport a 43-foot-long piece of hardware, not to mention a 16 foot wide, 7 foot tall simulation of the crew module that will take our astronauts to the moon.


The Ares I-X launch abort system (LAS) simulator rolled off an Air Force C-5 transport Jan. 28 after landing on the NASA Kennedy Space Shuttle runway.  The LAS simulator, which represents the tip of the Ares I-X rocket, was designed and built at NASA Langley Research Center. 

The Ares I-X crew module, in blue, and supporting hardware were unloaded after the two-hour flight from Langley to Kennedy.

The crew module and launch abort system simulators, wrapped in blue, took their place among other Ares I-X hardware in the Vehicle Assembly Building at NASA Kennedy.
