ISS038-E-022882 (27 Dec. 2013) --- Russian cosmonauts Oleg Kotov (right), Expedition 38 commander; and Sergey Ryazanskiy, flight engineer, attired in Russian Orlan spacesuits, participate in a session of extravehicular activity (EVA) in support of assembly and maintenance on the International Space Station. During the eight-hour, seven-minute spacewalk, Kotov and Ryazanskiy worked with two high-fidelity cameras, removed the Vsplesk experiment package and jettisoned it and replaced it with hardware for a more sophisticated earthquake-monitoring experiment, Seismoprognoz, which they attached to a Zvezda handrail.
