Inside the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, a construction worker continues with refurbishment and upgrades to the 175-ton crane on the ground floor of the transfer aisle. The crane's 45-year-old controls are being upgraded to improve reliability, precision and safety. The Ground Systems Development and Operations Program is overseeing upgrades and modifications to the crane so that it can support lifting needs for NASA and other exploration vehicles, including the agency's Space Launch System and Orion spacecraft.
