On the way into the airlock, the cosmonauts attempted to retrieve Vinoslivost, a materials-exposure experiment installed outside the Poisk module in February 2012. However, the 18 x 12-in. aluminum experiment panel slipped away from Vinogradov. Mission Control reports the 6.5-lb. panel moved away from the station on a retrograde trajectory and is not expected to pose a collision threat to the station.
