STS070-309-026 (13-22 JULY 1995) --- A close-up view of the space shuttle Discovery?s window number 6, on the forward starboard side, nearest the pilot?s station. A small impact in the window, about 1/16 inch in size, is clearly seen in the corner. Crew members told a August 11, 1995, gathering of Johnson Space Center (JSC) employees that a small piece of debris apparently struck the window during Discovery?s wing velocity vector mode. It was noticed when the astronauts awoke from their sleep period. Though watched closely during the remainder of the mission, the impact never caused a major concern.
