Inside the Vehicle Assembly Building, or VAB, at NASA's Kennedy Space Center in Florida, a crane is being used to lower the 175-ton crane from Level 16 down to the transfer aisle floor. Upgrades to the crane's 45-year-old controls will be performed in order to improve reliability, precision and safety.

The Ground Systems Development and Operations Program is overseeing upgrades and modifications to the VAB. The crane will be upgraded so that it can support lifting needs for NASA and other exploration vehicles, including the agency's Space Launch System and Orion spacecraft.
