During a 5 hour 30 minute spacewalk, astronauts Wolf and Kopra installed the Japanese Exposed Facility to the KIBO science module. Great use was made of several robotic arms on the shuttle Endeavor and the ISS. The JEF will allow experiments to be placed outside the station, tended by the robotic arms, to expose materials to the effects of space vacuum and environmental conditions.
NASA engineers have also reached the conclusion that no significant damage was done to the shuttle tiles and no further inspection will be necessary. The next spacewalk will be Monday.
