A heavy-lift crane lifts the second half of the C-level work platforms, C north, for NASA’s Space Launch System (SLS) rocket, high up from the transfer aisle of the Vehicle Assembly Building (VAB) at NASA's Kennedy Space Center in Florida. The C platform will be moved into High Bay 3 for installation on the north side of High Bay 3. The C platforms are the eighth of 10 levels of work platforms that will surround and provide access to the SLS rocket and Orion spacecraft for Exploration Mission 1. The Ground Systems Development and Operations Program is overseeing upgrades and modifications to VAB High Bay 3, including installation of the new work platforms, to prepare for NASA’s Journey to Mars.

Inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, the second half of the C-level work platforms, C north, for NASA’s Space Launch System (SLS) rocket, is lowered into position for installation on the north side of High Bay 3. In view below are the seven levels of previously installed platforms. The C platforms are the eighth of 10 levels of work platforms that will surround and provide access to the SLS rocket and Orion spacecraft for Exploration Mission 1. The Ground Systems Development and Operations Program is overseeing upgrades and modifications to VAB High Bay 3, including installation of the new work platforms, to prepare for NASA’s Journey to Mars.

High up in the Vehicle Assembly Building (VAB) at NASA's Kennedy Space Center in Florida, a crane lowers the final work platform, A north, for installation in High Bay 3. The platform will be installed and secured on its rail beam high up on the north wall of the high bay. The installation of the final topmost level completes the 10 levels of work platforms, 20 platform halves altogether, that will surround NASA's Space Launch System rocket and the Orion spacecraft and allow access during processing for missions, including the first uncrewed flight test of Orion atop the SLS rocket in 2018. The A-level platforms will provide access to the Orion spacecraft's Launch Abort System for Orion lifting sling removal and installation of the closeout panels. The Ground Systems Development and Operations Program, with support from the center's Engineering Directorate, is overseeing upgrades and modifications to the VAB, including installation of the new work platforms.

A heavy-lift crane lifts the second half of the C-level work platforms, C north, for NASA’s Space Launch System (SLS) rocket, up from the transfer aisle floor of the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida. Large Tandemloc bars have been attached to the platform to keep it level during lifting and installation. The C platform will be installed on the north side of High Bay 3. The C platforms are the eighth of 10 levels of work platforms that will surround and provide access to the SLS rocket and Orion spacecraft for Exploration Mission 1. The Ground Systems Development and Operations Program is overseeing upgrades and modifications to VAB High Bay 3, including installation of the new work platforms, to prepare for NASA’s Journey to Mars.
