51I-35-075 (30 Aug 1985) --- Typhoon Pat was photographed on the morning of August 30th at a position of approximately 25 degrees N, 131 degrees E. Stereoscopically-overlapping photographs taken by the 51I crew provide much more detail of the three-dimensional structure of tropical cyclones than can be determined from data returned from meteorological satellites. The 51I shuttle mission was launched on August 27 and landed September 3. The mission was flown in the space shuttle orbiter Discovery.
