KENNEDY SPACE CENTER, FLA. - Japanese astronaut Koichi Wakata gestures as he examines the spar installation (behind him) on the wing of the orbiter Atlantis. Reinforced Carbon Carbon (RCC) panels are mechanically attached to the wing via the spars - a series of floating joints - to reduce loading on the panels caused by wing deflections. The aluminum and the metallic attachments are protected from exceeding temperature limits by internal insulation.
