NASA is investigating another mishap at the Kennedy Space Center, this time an accident involving the remodeled fuel tank to be used for the next shuttle mission, the agency said on Wednesday.
Technicians were replacing a vent valve near the top of the 154-foot (47-meter) tall tank on Tuesday when a Halogen work lamp fell and hit the tank's foam insulation.
Preliminary inspections show the impact left five small indentations, with the largest about the size of a stick of gum, and one 6-inch (15-centimeter) to 7-inch (17-centimeter) long scratch, said Marion LaNasa, spokesman for tank manufacturer Lockheed Martin Corp.
A detailed inspection of the area was under way, LaNasa said, but the incident was not expected to affect the shuttle's targeted July 1 liftoff.
