Spacewalkers Mike Foreman and Randy Bresnik deployed the inboard Payload Attach System (PAS) on the space-facing side of the Starboard 3 truss. The PAS is a cargo attachment point, and this is the location where the Alpha Magnetic Spectrometer will be installed during STS-134 next year. Foreman and Bresnik also installed a wireless video system that allows spacewalkers to transmit video to the station and relay it to Earth.
The astronauts continue to be well ahead of schedule. Next, they will deploy the final PAS, the attach system on the Earth-facing side of the Starboard 3 truss section. This is where the Express Logistics Carrier 4 will be installed next year. This task had been planned for the third spacewalk.
