Supersize Me!

Posted on by .



The Super Stack 1 assembly is now complete with the mating (stacking) of the forward assembly to the fifth segment simulator. Stack one is made up of eight individual pieces: interstages 1 and 2, the frustum, the forward skirt extension, the forward skirt and the aft, center and forward segments of the fifth segment simulator. It also includes two internal elements, the roll control system and the first stage avionics module.

All five super stack assemblies are now complete in High Bay 4 of the VAB and are ready for stacking on the mobile launcher platform in High Bay 3 later this month.

Just so you know, the reason the rocket is separated into these super stacks has to do with the height and weight of each piece for crane loads during lifting operations.

The CM-LAS and the Birdcage

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.
