NASA's basic goal in the U.S. stratospheric research program was to determine the normal makeup of the upper atmosphere with emphasis on understanding the dynamic processes occurring and the perturbations caused by natural and man-made events, Dr. James C. Fletcher, NASA Administrator, said at a hearing before the Senate Committee on Aeronautical and Space Sciences. NASA's current high altitude program was being carried out by conventional and special purpose aircraft such as the U-2, instrumented packages placed on commercial aircraft, instrumented balloons, sounding rockets, and computer modeling techniques. Satellites still provided the best potential for continuing repetitive global observations of the upper atmosphere. The Nimbus satellites had measured properties affecting the ozone and had made vertical profiles of the upper atmosphere. Atmospheric Explorer (AE) satellites had made coordinated investigations of photochemical processes in the upper atmosphere caused by solar ultraviolet radiation.
Dr. Fletcher said that NASA would continue these efforts and had plans for new atmospheric studies. In addition to payloads planned for launch on the Space Shuttle, NASA would use instrumented aircraft, balloons, and sounding rockets to study the effects of chlorofluoromethanes, or Freon, on atmospheric ozone.

Reduction-in-force and reduction-in-grade notices were sent to 213 Civil Service employees at Marshall Space Flight Center as a result of the reduction in the end-of-FY 1975 personnel ceiling. In addition to the 93 persons separated and the 120 persons reduced in grade, 191 MSFC employees received reassignments as part of a reclassification survey conducted during the summer of 1974.
