International Space Station (ISS)

The main objective of the STS-100 mission, the sixth International Space Station (ISS) assembly flight, was the delivery and installation of the Canadian-built Space Station Remote Manipulator System (SSRMS), or Canadarm2. In this photograph, astronaut Scott E. Parazynski, mission specialist, works with cables associated with the robotic arm during one of two days of extravehicular activity (EVA). Both space walks were shared with Chris A. Hadfield, mission specialist representing the Canadian Space Agency (CSA), who is visible in the helmet visor of Parazynski. STS-100 launched April 19, 2001 aboard the Space Shuttle Orbiter Endeavour for an 11 day mission.
