Space Shuttle more vulnerable than suspected.(Aerospace)
Advanced Composites Bulletin, March, 2005
Tests performed by the US National Aeronautics and Space Administration (NASA) on reinforced carbon-carbon components (RCCs) used to protect the Space Shuttle have shown that even small pieces of insulating foam can cause potentially catastrophic cracks and damage to the heat resistant panels.
The testing showed that a piece of insulating foam weighing just 10.48 g (0.37 of an ounce), falling off the top of the external fuel tank during take-off and striking a sensitive area of the spacecraft's wing could cause enough structural damage to an RCC panel to lead to the destruction of the spacecraft when it re-enters the Earth's atmosphere.
The RCC system (including all panels, supporting structure and attaching hardware) is an essential component of the...
