NASA internal slide discusses foam penetration risk to shuttle tiles

NASA internal slide discusses foam penetration risk to shuttle tiles The passage provides technical details about foam penetration tests and a NASA internal slide, but it does not identify any high‑ranking officials, financial transactions, or misconduct. It offers limited investigative value beyond confirming known shuttle safety concerns, which are already public. Key insights: SOFI (foam) can penetrate shuttle tile coating at high velocity and mass.; Test data shows over‑prediction of penetration in prior models.; Flight conditions involve foam impact speeds far exceeding test parameters.
