Endeavour performed a series of burns that allowed the shuttle to close in on the Hubble Space Telescope at a rate of per 95-minute orbit. The crew made a detailed inspection of the payload and checked out both the robot arm (Canadarm) and the spacesuits. All of Endeavours systems functioned well as the crew got a full day's sleep in preparation for the evening's rendezvous. At the end of Flight Day 2, Endeavour was behind HST and closing.
