CAPE CANAVERAL — NASA is taking a close look at two new problems on space shuttle Endeavour.
A round ceramic spacer near one of the cockpit windows is sticking out. And a thermal tile repair made before the flight has failed, and the original crack is back, right over the cockpit.
Mission management team leader LeRoy Cain said Wednesday that neither problem appears to be serious. But he said everyone wants to be “very vigilant and take a closer look” in case spacewalking repairs are needed.
