NASA is examining photos of Space Shuttle Endeavour after discovering what appears to be damage to a critical heat protection tile. Ice is believed to have broken off the external fuel tank during lift-off and struck the shuttle.
  NASA wants to study the problem before choosing a course of action. Photos taken of Endeavour’s belly by the crew of the International Space Station shows a three-inch-by-three-inch gouge in at least one black heat tile under the shuttle’s right-hand wing near one of the main landing gear doors. NASA’s John Shannon says if the damage is life-threatening and too extensive to repair, a rescue shuttle could be sent to save the astronauts.
  NASA runs such analysis every single flight. Up to now, Space Shuttle Endeavour has at least 68 days of consumables to support ten crew members and NASA can get a shuttle ready by October 5th.
  Repair options include a heat resistant paint, a protective plate that could be screwed into the gouge place or a thick compound that can be squirted.
