These are two composite images of space shuttle Columbia during ascent on STS-107. The images are both derived from an average of 17 video fields totaling about one-quarter of a second of video. The left space shuttle Columbia image is taken from video before a debris strike recorded by other cameras. The one on the right is taken from video after a debris strike recorded by other cameras. The imagery from video was of too low resolution, however, to be significant for use in an engineering analysis that was performed during space shuttle Columbia's flight regarding the debris strike.
