Shuttle crew confident about fix

Mission managers decided Monday to remove two gap fillers that are protruding from areas between heat-shielding tiles on the Discovery's underbelly. During the spacewalk, Mission Specialist Steve Robinson will venture under the Shuttle on the tip of the International Space Station's robotic arm, locate the protrusions and gently tug until they come out. If that does not work, Robinson will have tools to cut off the protrusions.
"This is going to be a very delicate task," Robinson said, "but as I say a simple one."
