English: This is one of a series of digital still images showing astronaut Tom Marshburn performing his first spacewalk and the Endeavour crew's second of the scheduled five overall in a little more than a week to continue work on the International Space Station. Astronauts Marshburn and Dave Wolf (out of frame), both mission specialists, 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.
