Wilson "Don't drop it!", Parazynski then moved on and installed handrails onto Harmony, while Tani went to inspect some items requested by the managers, including handrails on a Crew and Equipment Translation Aid (CETA) cart, that was considered as a possible cause of Rick Mastracchio's glove tear on STS-118. Tani noted the handrail appeared to be intact, with no obvious sharp edges. Tani then moved on to the Solar Alpha Rotary Joint (SARJ) that has had an intermittent vibration for over a month. After removing the cover from the joint, Tani called down to the team to let them know he saw some metal shavings, and some wear patterns and discoloration on one of the rings inside the joint. "It's like the result that you get with the metal, iron filings and you put a magnet under it and they stand straight up." Tani collected some of the shavings onto some tape, which returned to Earth with the shuttle for further analysis. Managers decided to add a task to Tuesday's EVA, having Parazynski inspect the port (left side) SARJ, using photography and video to compare it to the starboard SARJ inspected by Tani. October 29 (Flight day 7) The two crews used the morning to move the P6 truss from its overnight position on the station's robotic arm, over to the shuttle's robotic arm. The crew then moved the station's arm along the mobile transporter to an outboard work site that allows attachment of the P6 truss to its new location on the P5 truss on Tuesday. Managers on the ground had Whitson perform an experiment on the shavings Tani collected from the SARJ on Sunday's EVA, putting a magnet under a slip of paper, and testing to see if the shavings collected on the paper, to ascertain if they were metal. The test confirmed the particles collected by Tani were ferrous. This information allowed the managers on the ground to rule out some possibilities of the origin of the particles, such as the thermal covers, which are made of aluminized mylar. The Mission Management Team discussed the SARJ issues with the ISS team, and decided to add an extra docked day to the mission, between flight days 11 and 12. The new plan changed the objectives of EVA four from the heat shield repair materials testing, to a more thorough inspection of the starboard SARJ. With the new flight
