 Using the shuttle robotic arm and the Orbiter Boom Sensor System (OBSS), the crew went through a detailed inspection of the orbiter's thermal protection system (TPS) tile and Reinforced carbon-carbon (RCC) surfaces.During the inspection, engineers on the ground noticed a small area of tile on the forward area of the shuttle's right wing that appeared to have suffered some damage during ascent.Mission managers called up to the crew to alert them of the find, advising Altman ("Scooter") that one of the orbiter's wing leading edge sensors recorded a debris event during ascent, around 104 – 106 seconds following liftoff, which may have been the cause of the damage seen in that area.
