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.

Every time NASA launches a space shuttle we see a lot of reporters and media representatives descend on the press site at Kennedy Space Center. Last week as we got ready to launch STS-119 we thought it would be an excellent opportunity to take some of the reporters around to see the Ares I-X hardware. Right now, most of the pieces of the rocket are at KSC in various stages of processing and preparation, so there was plenty to see.
About 30 media reps joined us for a quick presentation and a Q&A session with Ares I-X Mission Manager, Bob Ess and Deputy Mission Manager, Jon Cowart. Afterward, everyone jumped on a bus and headed out on a tour of the processing facilities. We all got an up-close view of the hardware, the facilities and the people of the Ares I-X mission.
First, we stopped at Launch Pad 39B — the one Ares I-X will use — were we got a quick explanation of work being done to prepare the pad for launch. The reporters snapped shots of the new, 600-foot lightning towers surrounding the pad.
Then we went to the Assembly Refurbishment Facility, or ARF (yeah, I know), where we saw pieces of the first stage, including the aft skirt, forward skirt extension, forward skirt and frustum. Jon showed us all around and explained how each of the pieces will fit together to make the complete first stage.
The tour ended in the Vehicle Assembly Building — where the rocket will be stacked prior to being rolled out to the launch pad — where media took a peek at the pieces of hardware — remember the tuna cans? — that make up the upper stage simulator, as well as the simulated crew module and launch abort system that will top off the 327-foot vehicle for the test flight.
Take a look at this photo:
That’s definitely hardware, but it’s not a space shuttle! It is an Ares vehicle being stacked in the Vehicle Assembly Building at Kennedy Space Center. The Constellation Program is on the move towards the Ares I-X launch and things are moving along pretty well. More and more flight hardware is pouring into KSC and the Ares I-X team is now starting to put the rocket together.
In the center of the photo, the ballast is being lowered into one of the upper stage simulator segments. The ballasts mimic the weight of the solid rocket fuel that will be needed to launch the Ares I — a total of weight of about 160,000 pounds. It’s important that Ares I-X carry these ballasts so it can to gather important data that will help engineers build the Ares I. The upper stage simulator segments are nicknamed the “tuna cans” because they look like…well tuna cans. They simulate what will be the upper stage rocket on the Ares I.
