The second half of a new work platform was lifted and installed March 7 in High Bay 3 inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida. The newly installed platform is the first of 10 new work platform levels that will provide access to NASA’s Space Launch System (SLS) rocket and Orion spacecraft for Exploration Mission-1.

During the installation process, an overhead crane that can hold as much as 250 tons was used to lift the second half of the K-level work platforms up from High Bay 4, move across the transfer aisle, and lower it into High Bay 3. The platform was secured into position, about 86 feet above the VAB floor, or nearly nine stories high. The K-level platforms will provide access to the SLS core stage and solid rocket boosters during processing and stacking operations on the mobile launcher.

A total of 10 levels of new platforms – 20 platform halves altogether – will surround the SLS rocket and Orion spacecraft and provide access for testing and processing. The giant steel platforms, each measuring 38 feet long and 62 feet wide, will be attached to rail beams that will provide structural support and contain the drive mechanisms to move them in and out or up and down as needed.

The Ground Systems Development and Operations Program is overseeing upgrades and modifications to the VAB, including installation of new work platforms, to prepare for NASA’s journey to Mars.
