HOUSTON - ENDEAVOUR'S seven astronauts entered their last full day in space Saturday awaiting word if mission managers had cleared the space shuttle for a return to Earth.
Astronauts used a laser-tipped boom on Friday to conduct a final inspection of Endeavour's protective heat shield to make sure the shuttle is free of any damage from space-junk hits which could imperil the astronauts during the fiery re-entry into Earth's atmosphere.
