In this one of a series of digital still images, astronaut Dave Wolf performs his second spacewalk, which is also the second of five scheduled spacewalks for the STS-127 mission. Astronauts Wolf and Tom Marshburn (out of frame) successfully transferred a spare KU-band antenna to long-term storage on the space station, along with a backup coolant system pump module and a spare drive motor for the station's robot arm transporter. Installation of a television camera on the Japanese Exposed Facility experiment platform was deferred to a later spacewalk.
