NASA Abandons Rigid Overwrap For Patching RCC Holes

After encountering "significant technical challenges," NASA is abandoning attempts to develop a rigid overwrap to patch large holes in the space shuttle's reinforced carbon-carbon (RCC) panels in the event of damage during flight, and instead is pursuing other methods that probably won't be ready in time for the shuttle's return to flight, according to agency officials.

The shuttle program plans to fly again in March or April of next year. The Columbia Accident Investigation Board (CAIB) specified that NASA must develop methods of on-orbit thermal protection system (TPS) inspection and repair for the shuttle before that flight. Columbia was lost after foam debris from its external tank punched a large hole in one of the orbiter's RCC leading edge panels.
