|Installed the Obstanovka plasma waves and ionosphere experiment to the exterior of the Zvezda service module. Also replaced a faulty retro-reflector device used as navigational aids for the Automatic Transfer Vehicle and retrieved the Biorisk microbe exposure experiment. An attempt to retrieve the Vinoslivost materials sample experiment failed when it was accidentally dropped while being taken back to the Pirs module airlock.{{cite web|url=http://www.nasaspaceflight.com/2013/04/cosmonauts-russian-spacewalk-iss-rs32/|title=Cosmonauts successfully conclude Russian spacewalk|author=Pete Harding|date=2013-04-19|access-date=2013-04-19}}{{cite web|url=http://www.nasa.gov/mission_pages/station/expeditions/expedition35/eva_041913.html|title=Spacewalkers Deploy Plasma Experiment, Install Navigational Aid|author=NASA|date=2013-04-19|access-date=2013-04-19}}

|Took the Olympic torch for the 2014 Winter Olympic Games to the outside of ISS. They also continued work on an extravehicular activity workstation and biaxial pointing platform by removing launch brackets and bolts, as well as retrieving an experimental package. The planned installation of a foot restraint on the mounting seat of the workstation was deferred to a future spacewalk after the spacewalkers noticed some issues with its alignment.{{cite web|url=http://www.nasaspaceflight.com/2013/11/russian-eva-olympic-torch-relay-space/|title=Troublesome ISS EVA conducts Olympic torch relay in space|author=Chris Bergin|date=2013-11-09|access-date=2013-11-11}}{{cite web|url=http://www.nasa.gov/content/olympic-torch-highlights-station-spacewalk/|title=Olympic Torch Highlights Station Spacewalk|author=NASA|date=2013-11-09|access-date=2013-11-11}}
