Spacewalks
On 18 August 2005 19:02 UTC (3:02 p.m. EDT) the crew started a 4 hour, 58 minute spacewalk. They removed and brought inside the station a Russian Biorisk experiment container housing bacteria from the outside of Pirs; an MPAC (a micrometeoroid and orbital debris collector) and SEED (a materials exposure array) panel from the Zvezda Service Module; and the Matroska experiment, (radiation dosimeters in human-tissue-equivalent material). They installed a television camera on Zvezda, and checked a Korma contamination-exposure experiment tablet, and removed and replaced a materials exposure experiment container.
