At 3:25 p.m. EST space shuttle robotic arm operators Leland Melvin and Randy Bresnik handed off the Express Logistics Carrier -1 (ELC) to space station robotic arm operators Jeff Williams and Barry E. Wilmore.
The ELC is a platform that supports external payloads mounted to the space station’s trusses and weighs almost 14,000 pounds. The ELC carries a number of spare parts that will sustain station operations after shuttles are retired.
