Because the spacewalk is behind the original timeline, managers shuffled the tasks. They decided to defer a planned chore calling for Clay Anderson to retrieve a light-weight adapter plate assembly from the Columbus laboratory. Instead they asked him to perform two tasks required for space shuttle Atlantis’ STS-132/ULF-4 mission next month, relocating a portable foot restraint and preparing cables on the Zenith 1 truss for a spare Space to Ground Ku-Band antenna.
Rick Mastracchio carried a grapple bar from the old Ammonia Tank Assembly to the new one, where he is bolting it in place. He also will perform bolt re-tightening of the Port 1 radiator grapple fixture stowage beam.
