The forward assembly, which is affectionately known around here as the “snow cone,” was rolled out of the Assembly Refurbishment Facility this morning on its way to the Vehicle Assembly Building. Employees and media came out to get a peek at the hardware.
The assembly was rolled into the transfer aisle of the Vehicle Assembly Building, where it will wait to be lifted by crane into the high bay where the upper stage of the rocket is being assembled into its five super stacks. When these stacking operations begin later this month, it will be the first time a new vehicle has been stacked on NASA’s Mobile Launch Platform in more than 25 years!
The forward assembly connects the first stage motor segments to the upper stage simulator. Weighing more than 40,000 pounds, the assembly houses three newly designed descent parachutes for first stage recovery.
With 300 employees looking on, the Ares I-X aft skirt rolled out of the Assembly Refurbishment Facility. Senior management including Kennedy Center Director Bob Cabana, Mission Manager Bob Ess, ATK Program Manager Joe Oliva and United Space Alliance Associate Program Manager Roger Elliot spoke at the “pep rally” type event.
The aft skirt is on its way to the Rotation Processing and Surge Facility where it will be attached to the aft motor segment later this week, forming the aft assembly. Although this was an aft skirt for the shuttle program, the team made many modifications for this new vehicle. Some modifications include adding deceleration and tumble motors, avionics and a controller for the auxiliary power unit.
Once the aft assembly is complete, it will be moved to the Vehicle Assembly Building to begin stacking operations in late June.
The Ares I-X team was very excited on Friday when the frustum rolled into the Assembly Refurbishment Facility at Kennedy Space Center, making it the final newly manufactured segment to arrive for this summer’s Ares I-X launch.
The frustum is the segment between the Forward Skirt Extension and the upper stage of the Ares IX launch vehicle. As you can see, it looks a lot like a giant funnel. Its main function is to transition the flight loads from the thicker upper stage to the thinner first stage. It weighs in at approximately 13,000 pounds, and is 10 feet long. It’s composed of two machined, aluminum-forged rings that are attached to a conic section. The large diameter of the cone is 18 feet, while the small diameter is 12 feet. The thickness of the cone is only 1 ¼ inches! Kind of amazing.
Now that the frustum is at Kennedy, technicians will begin the final processing and it will be integrated to the forward skirt and forward skirt extension to make the forward assembly. The completed forward assembly will be moved over to the Vehicle Assembly Building for stacking operations scheduled to begin in April.
With the arrival of the frustum, the team now waits for the final rocket components to arrive — the motors. The rocket motors, manufactured by ATK in Utah and shipped via rail to Kennedy, are scheduled to arrive next month.
