Astronaut Michael J. Massimino, mission specialist, waves to crewmates on the other side of the aft flight deck windows on Columbia, while equipped with his extravehicular mobility unit (EMU) space suit and attached to the end of the Remote Manipulator System (RMS) arm in the shuttle's cargo bay. This day's space walk went on to see astronauts James H. Newman and Massimino replace the port flexible solar array on the Hubble Space Telescope (HST), partially visible in the background. On the previous day, astronauts John M. Grunsfeld and Richard M. Linnehan had replaced the starboard solar array on the giant telescope.
