Space flight operations for world development.

Mission objectives, hardware development efforts, and aspects of international cooperation are covered in an outline of space flight programs planned by the United States for the forthcoming decade. Scientific experiments envisioned for the Apollo 17 mission and for the Skylab program are discussed along with the current status of the joint Apollo/Soyuz test project specified by the U.S.-USSR space agreement of May 1972. The Space Shuttle, Space Tug, and Sortie Laboratory projects are outlined with emphasis on the use of experience and hardware gained in earlier phases of this space program.
