replay of the Columbia accident.As a pair of spacewalking astronauts installed a new beam to the international space station on Saturday [link widoczny dla zalogowanych], engineers back on Earth scrutinized images of the gouge [link widoczny dla zalogowanych], believed to be the result of a strike by ice at launch.The ice, which would have come from the external fuel tank [link widoczny dla zalogowanych], is denser than the tank's insulating foam and even a small piece could cause major damage to the shuttle's thermal covering.In a scene eerily reminiscent of the foam smack to Columbia four years ago, radar showed a whitish spray or streak emanating from Endeavour's right side 58 seconds after Wednesday evening's liftoff. The chairman of NASA's mission management team was quick to point out that the spray looked much smaller than the one during Columbia's launch.Nonetheless, the similarities immediately grabbed the attention of mission managers. The 1986 Challenger launch explosion already was at the forefront of everyone's minds, given the presence of teacher-astronaut Barbara Morgan — Christa McAuliffe's backup — aboard Endeavour.Mission managers promptly ordered a focused inspection of the gouged area Sunday, using Endeavour's 100-foot, laser-tipped robot arm and inspection boom. They also had engineers and other experts poring over the radar launchyilai：
